Although these changes occur throughout the lifespan, the most important changes for parents occur between birth and 18 years of age. Gross motor skills help to control the large muscles of the body. These are associated with the movement of the torso, arms and legs. Fine motor skills are the ability to move the smaller muscles of the body. These are associated with the control of the tongue and fingers. In general, gross motor skills develop before fine motor skills. One of the first and most important parts of the body the newborn must gain control of is the head. Control of the head is essential to direct attention. The eyes can only see what is within a certain range of vision, generally in front of the head. It takes the first four weeks of life for babies to learn how to control and lift their head, though some babies may take as long as five months to achieve this. A major type of behaviour that develops during infancy is reaching. At birth, infants reach without a real intention. They reach for a stimulus, and there is no coordination of reaching and grasping. As a result, infants reach for objects and fail to grasp them because they have not learned how to control or synchronize their grasping with their reaching. Between 3-5 months of age there is a type of intentional reaching that is called ballistic reaching. It is called ballistic because it seems as though the infant is throwing his/ her hand at the target. It is not very accurate, and infants often miss their target. In addition, even when the hand does reach the target, it often fails to grasp the target. Between 5-7 months of age infants improve their ability to coordinate their vision and have a control of their reaching. As a result, reaching becomes more deliberate and accurate. This type of reaching is called guided reaching. However, it is still 8 somewhat imprecise due to the persistent problem of coordination. Finally, by about 11 months of age, infants succeed in coordinating their reach and grasp, with a corresponding increase in the accuracy of reaching and grasping. Infants also appear to use both hands equally for reaching and grasping until about nine months of age. However, between 9-13 months of age, infants develop a preference for one hand over the other. By 13 months of age most infants tend to display a clear preference for their right hand. Another major type of behaviour that develops during infancy is walking. By about four months of age most babies can sit with support. They can sit and grasp by about five months, and they can sit without support by about seven months of age. By about eight months, most babies can crawl. They can also stand up if they have help. By the end of the eighth month most babies develop the ability to pull themselves up to a standing position. However, it takes them another 2-3 months to learn how to stand alone. By about 12 months, most infants have learned how to walk alone. During the next few months infants refine their walking abilities by learning how to walk sideways and backwards (between 13-18 months). They expand these abilities still more by learning how to run between 14-20 months of age, though they may not be able to run smoothly until about two years of age. Further developments, such as turning while running will take a little longer, and occur during the childhood years. Fine motor skills are the ability to use the small muscles of the body, especially the hands and fingers. Although these skills develop at the same time as gross motor skills, they tend to lag behind a bit, because the large muscles must be able to put the body in place for the small muscles to play their part. 9 Between 4-6 months of age infants become fairly successful at reaching for and grasping objects, though a few trials and errors may be common. An important milestone is reached at about nine months of age when infants develop the ability to hold small objects between the thumb and forefinger. This is called the pincer grasp. It is important because it eventually makes many other behaviours possible, such as writing or buttoning clothing. Between 10-12 months of age infants typically are able to hold a spoon in their hands and feed themselves, though their aim may still be rather poor. As the baby learns how to control his/ her eyes and head, and other muscles, it soon finds that he/she cannot always achieve his/ her goals without coordinating different parts of the body at the same time. Infants must learn how to control their eyes and head before they can intentionally grasp objects, or catch a ball. From this point of view, the development of the infant is a function of their innate physical characteristics and the relatively constant state of the physical world they inhabit, e.g., in terms of the laws of physics. In addition, the infant must learn how to control each subsystem (e.g., the eyes) before it can coordinate the activities of several sub systems (e.g., the eyes, legs, arms, and hands) to accomplish goals (e.g., catch a ball). PHYSICAL DEVELOPMENT: An infant's physical development infant begins at the head, then moves to other parts of the body (for example, sucking comes before sitting, which comes before walking). 10 Newborn - 2 months  Can lift and turn the head when lying on his or her back  Hands are fisted, the arms are flexed  Neck is unable to support the head when the infant is pulled to a sitting position  Primitive reflexes include: o Babinski reflex -- toes fan outward when sole of foot is stroked o Moro reflex (startle reflex) -- extends arms then bends and pulls them in toward body with a brief cry; often triggered by loud sounds or sudden movements o Palmar hand grasp -- infant closes hand and "grips" your finger o Placing -- leg extends when sole of foot is touched o Plantar grasp -- infant flexes the toes and forefoot o Rooting and sucking -- turns head in search of nipple when cheek is touched and begins to suck when nipple touches lips o Stepping and walking -- takes brisk steps when both feet are placed on a surface, with body supported o Tonic neck response -- left arm extends when infant gazes to the left, while right arm and leg flex inward, and vice versa 3 - 4 months  Better eye-muscle control allows the infant to track objects 11  Begins to control hand and feet actions, but these movements are not fine- tuned. The infant may begin to use both hands, working together, to accomplish tasks. The infant is still unable to coordinate the grasp, but swipes at objects to bring them closer  Increased vision allows the infant to tell objects apart from backgrounds with very little contrast (such as a button on a blouse of the same color)  Infant raises up (upper torso, shoulders, and head) with arms when lying face down (on tummy)  Neck muscles are developed enough to allow the infant to sit with support, and keep head up  Primitive reflexes have either already disappeared, or are starting to disappear 5 - 6 months  Able to sit alone, without support, for only moments at first, and then for up to 30 seconds or more  Infant begins to grasp blocks or cubes using the ulnar-palmar grasp technique (pressing the block into palm of hand while flexing or bending wrist in) but does not yet use thumb  Infant rolls from back to stomach. When on tummy, the infant can push up with arms to raise the shoulders and head and look around or reach for objects. 12  6 - 9 months  Crawling may begin  Infant can walk while holding an adult's hand  Infant is able to sit steadily, without support, for long periods of time  Infant learns to sit down from a standing position  Infant may pull into and keep a standing position while holding onto furniture 9 - 12 months  Infant begins to balance while standing alone  Infant takes steps holding a hand; may take few steps alone TODDLERS’ PHYSICAL DEVELOPMENT: Throwing and kicking a ball (12 months) Soon after his first birthday, the child shows interest in ball play -- first by throwing, then by kicking at age 2 13 Pushing and pulling (12 to 18 months) Once the child becomes a confident walker, he can discover the joy of dragging or pushing toys along. He improves his coordination while walking forward and occasionally looking back. Squatting (12 to 18 months) Till now, the baby has had to bend down to pick things up off the ground. But soon, he will attempt to squat instead. Climbing (12 to 24 months) Toddlers climb up on the kitchen table (or on the desk or the bed) for the obvious reason: Because it's there. Kids this age are trying to find a balance between risk and challenge. Climbing is an important physical milestone, though. It helps the child to develop the coordination he needs to master skills like walking up steps. Running (18 to 24 months) Some kids seem to go from crawling to sprinting in two seconds flat. Others take more time. That is because kids fall a lot when learning to run, and some are quite willing to risk it. 14 Jumping (24 to 36 months) Between 2 and 3 years, toddlers learn how to jump off low structures, and gradually how to jump from a standing position. Both these skills require bilateral coordination, or the ability to use both sides of your body to do something different. Developmental milestones include: By the 1st year  he can use his feet to push himself along on a ride-on. By 15 months  he can walk without help, though he will have his feet wide apart and his arms up to maintain balance  he can move from sitting to standing by using his hands to push himself up and stand up from sitting by using his hands By 1 half years  he can push a wheeled toy in front of himself  he has mastered the pincer grip and can now pick up small objects  he can build a tower  he can climb up onto low furniture such as chairs, coffee tables and lounges  he can scribble on paper 15  he can drink from a cup without any help By two years:  he can get up off the floor without having to use his hands  he can pull a toy by walking backwards  he can run in a direction and stop when he needs to  most toddlers can walk down stairs while holding onto a support by placing both feet on each step  he can push buttons and turn knobs MOTOR DEVELOPMENT: Gross Motor Skills Gross Motor development involves the larger, stronger muscle groups of the body. In early childhood, it is the development of these muscles that enable the baby to hold his/her head up, sit, crawl and eventually walk, run and skip. Between the ages of 12–18 months, a toddler  Starts walking independently  Attempts to run, or runs with stiff posture  Squats down to pick up something  Crawls up stairs and creeps back down  Can sit by ownself on a small chair  Pulls a toy behind himself/ herself while walking Between the ages of 18 months – 2 years, a toddler  Can walk up and down the stairs while holding someone’s hand  Can run quite well, though not very fast. 16  Jumps with feet together  Can jump down and forward  Likes to stand on tiptoe with support  Loves to throw a ball into a box  Able to kick a ball forward Between the ages of 2 – 2 ½ years, a toddler  Stands on tiptoes if demonstrated by elders  Jumps from bottom step  Begins to ride a tricycle, moving forward with feet on the floor  Catches a large ball with arms straight out Between the ages of 2 ½ - 3 years, a toddler  Can stand on one foot for some time  Walks downstairs with two feet on the same step  Loves to walk tiptoe  Starts riding a tricycle using the pedals  Can catch a ball with arms bent  Kicks a ball forward 17  PHYSICAL COGNITIVE SOCIAL NEW BORN: Uncoordinated, reflexive movements Physically explores Baby loves the the environment, comfort of mother, Repeated movements Toddlers feel safe lead to stimulation of with the mother. brain cells. 4- 5 MONTHS: Can grasp with a purpose, reach and Curious and Responds to social transfer objects from one hand to interested about the stimuli, shows another, roll over, plays with feet. environment emotions through facial expressions 9 MONTHS: Crawls, can stoop down and then Starts interacting recover, eye and hand coordination Can differentiate socially, likes to without any preference for hand between parents and play with parents others, problem and family members solving skill develops. 18 12 MONTHS: Starts walking Anxiety seeing Points at pictures strangers, likes to relating to verbal cue, play alone receptive language is better than expressive language, beginning of symbolic thinking 15 MONTHS: Development of more complex skills Attachment towards mother increases Learns through and can easily imitating complex recognize the near behaviour, can ones at home recognise known objects Parallel and symbolic play, starts imitating 2 YEARS: Can arrange toys and puzzles in order, uses Can climb up stairs first and then two word phrases down 19 20 PRE SCHOOLERS Physically active, cannot sit in one Have vivid Co operative in place for long imaginations, cannot playing, can have differentiate between imaginary play fantasy and reality mates Hopping, jumping, climbing, running, riding on big wheels and tricycles Receptive language is better than Develops fine and Improves fine motor skills with eye- expressive language gross motor skills hand coordination, can hold scissors till 4 years of age along with social and draw shapes skills Toilet trained between 3-3 half years Have an accurate memory Understands good and bad behaviour, feels bad for disobedience with Ego centric and parents illogical Curious about their own bodies and may even explore for Does not have a curiosity 21  proper understanding of time and sequence Curious and has no of events sense of privacy Vocabulary explosion Less emotional outbursts 22 PRE SCHOOLERS Skills that develop between the ages of 2 and 3 -runs forward - walks up and down stairs, alternating feet - jumps in place with both feet together - kicks a ball forward - uses one hand consistently in most activities - stacks up to 6 blocks - turns pages in a book one by one - imitates vertical, horizontal, and circular strokes Skills that develop between the ages of 3 and 4 - walks stairs without support - runs around obstacles - hops/balances on one foot for up to 5 seconds - pedals and steers a small tricycle - catches a bounced ball - holds a writing utensil between first two fingers and thumb - copies a cross and a square - uses scissors to cut on a line Skills that develop between the ages of 4 and 5 - balances on one foot for 10 seconds or more - jumps over objects 5 to 6 inches high - hops in a straight line on one foot - turns a somersault, swings, and climbs - gallops, may be able to skip - copies a triangle and other geometric shapes 23 - draws a person, prints some letters, colors within lines - cuts out simple shapes Perceptual Development While the ability to see, hear, and integrate sensory information is well established by six months of age, more complex and less obvious perceptual abilities develop throughout early childhood, for example, precision of visual concepts such as shape and size increases. Another aspect of perception often taken for granted is the ability to interpret pictorial representations of objects and people in the environment. Research shows that 3 year olds respond to depth cues like shading and the convergence of lines. Sensitivity to such cues, however, improves with age. The ability to obtain accurate information from pictures reflects children's eye movement fixation patterns. Young preschool children tend to have shorter eye movements and 24 focus their gaze to small areas near the middle or edge thus ignoring or missing much of the information available. The study of children's art provides some insight into the integration of their growing perceptual, cognitive and motor abilities. The 2.5 year old grasps a crayon in his hand and scribbles while the 4 year old can draw a recognizable human form know as the "tadpole person." The tadpole person is characterized by a big head, sticks for legs, and no body. The transition from drawing scribbles to the tadpole person usually occurs sometime between the 3rd and 4th year. Increased motor control and eye-hand coordination is one of the factors involved in this achievement. Drawing skills undergo a second transition sometime between the 4th and 5th year and the tadpole person is transformed into a complete person with a body as well as a head. Like the preschool child themselves, their art is delightfully full of life, energy, and creativity.. Drawings by youngsters of this age are characteristically colourful, balanced, rhythmic, and expressive. 25 COGNITIVE DEVELOPMENT: PARADOXES OF THE PRESCHOOL MIND According to Piaget, children's language acquisition reflects their emerging capacity for representational thought. The ways in which children think about the world are still primitive -- dreams come from street lamps, we think with our ears, clouds are alive, and the sun follows us when we move. Piaget proposed that 3, 4, and 5 year old children make errors because they are still unable to engage in true mental operations. This type of thinking therefore was termed "preoperational." According to him, the key feature of preschool thinking is that children can only focus their attention on one particular aspect at a time. This limitation is overcome at 6 or 7 years of age, when the transition to concrete operational thinking emerges. When this occurs, children are able to combine, separate, and transform information mentally in a logical manner. They know that the sun does not follow them and dreams do not come from street lamps. According to Piaget, preoperational thinking not only lacks logic but it is also egocentric. Another characteristic is known as complexive thinking, which is a chain of ideas in which each is linked to the preceding one but the whole is not organized into a unified concept. A third characteristic of preoperational thought is the capacity for deferred imitation which allows children to engage in pretend games. 26 Representation The ability to pretend is linked to the capacity for representation-the ability to think about the property of things without acting into it directly. The development of representation is the crux of all cognitive development during the preoperational period. Recent research shows that preoperational intelligence develop at two distinct levels, which are single representations that occur between the ages of 2 and 4, and the second between 4 and 6 years when children are capable of combining two or more representations (Case and Khanna, 1981; Gelman 1978; Kenny 1983). The transition from one of these levels to the next corresponds to a spurt in brain development. Observation of children in pretend play indicates that children at 2 years of age can control only one representation at a time. For example, in making a doll act as a person the child can represent the person doing only one thing at a time- a child walking, a man eating, a woman washing her hands. As the child matures single representations begin to include a set of related actions. Children combine characteristics into concrete social categories. For example, the child can make a doll perform a series of activities like putting on a saree, applying makeup on the face, and make her look like a bride. At about 4 years of age children begin to understand some relationships and complexities of social behaviour. They begin to understand other social relationships like husband-wife, mother-father, mother-child, etc. By relating various representations, the child now begins to understand relationships. This ability is reflected in the child's new attempts to influence behaviour. Strategies like "If you let 27 me play with your doll, I'll let you play with my basket," are quite common among 4 year olds. The preschool child is concerned about the people around them and how they relate to each other. Imitation Imitation is one of the most important ways children learn about the social world. During the sensorimotor period, before the capacity for representation develops, infants can imitate an action only at the moment it is observed. One result of representation skills is the capacity for deferred imitation-the process by which a child observes represented to themselves, and then at a later time called up from memory and actively imitated. Imitation also requires the ability to take another's point of view. Piaget pointed out that children often make serious mistakes by assuming that another person shares their own view of things. Everyone who has spent time with young children is aware of this egocentrism or the inability to take another's point of view. Even when preschool children are shown another person's perspective, they cannot keep it in mind and coordinate it with their own. They are not selfish but simply strongly believe in their own viewpoint. As cognitive skills increase, perspective-taking skills improve. At 2 and 3 years of age, children can take someone else's perspective only in the sense that they can understand a characteristic. By 4 and 5 years, children are able to understand the difference between another person's perspective and their own as long as they need to keep track of only one or two simple concrete factors. Thus, by 4 or 5 years of age, most children have taken a major step away from egocentrism. Memory 28 In order to understand another's perspective, the child must be able to remember. Memory is the ability to encode information, store it, and retrieve it. There are two kinds of memory, namely short-term and long-term. Short-term, also known as the working memory processes information retrieved within a few seconds or minutes of its being encoded. Preschoolers can use both short-term and long-term memory. For example when they have heard a brief list of words or seen a small group of pictures presented by an experimenter, 4-and 5-year-olds can often recall them immediately after presentation as well as older children can. Their long-term memory is amazing. Early development is characterized by changes in memory that are related to changes in cognitive development, including the increasing ability to focus attention, the ability to connect ideas with each other in a more logical way, and the ability to devise strategies for remembering. Although memory improves throughout childhood, important developmental changes take place during the preschool years. A major advance in memory abilities seem to begin at about 4 or 5 years when children start to recall items of some complexity and when they begin to monitor and manipulate their own memories. Play Preschool children love to play and they spend hours building and knocking down towers. They love to play house and act out stories with their playmates. Play in infancy consists mainly of imitations of repeated actions and sometimes with variations. In the preschool years, play becomes an important part in the child's life. Preschoolers love to play games that test and fine-tune their physical characteristics like running, climbing, swinging, throwing etc. They like to build things with mud, sand or blocks and they love to pretend. They make believe about all kinds of things everyday concerns, new things they have learned, and imagined adventure. 29 During the preschool years, children gradually play less by themselves and more with other children. At 2 years of age, solitary play is common and social interaction with other children remains simple. Parallel play is often seen among 2 year olds and becomes common by age 3. In parallel play, a child is influenced by the activities of other children but they do not actually cooperate in finishing a task. Two children may play with sand and imitate each other activities, but they will not work together to build the same castle. With an increase in thinking abilities, the complexity of children's solitary and social play also increases. At about 4 years of age cooperative play becomes the most important. In this form of play, many children create a city of blocks or play a game in which each child takes the role of a family member and together they act out the daily events. The content of play shows a new level of understanding and the child begins to play games with simple rules. At any age, children's problems are reflected in their play. Play provides a time when children can control things themselves. Piaget's view on the preschool child's development makes the child at the centre of his or her own world. Through active interaction, exploration, and observation of the environment, the child actively creates his or her own learning. Play facilitates the transition to higher levels of cognitive development. Play fosters a sense of self- esteem. That reinforces the actions of the children. As a result, in play, a child is always above his/ her daily behaviour. 30 Complex Thinking Play is mostly under the child's control and it clearly indicates some of the paradoxes in children's thinking processes. Preschool children usually have difficulty controlling or coordinating their thoughts. Even when they are capable of representational relations, they can deal with only simple, crude connections between ideas, so their thoughts tend to wander. One result of these difficulties is a thought pattern known as complexive thinking--the stringing together of ideas without a unifying concept or system. While there are connections between ideas, a single concept that ties them all together is lacking. Personification is an attribution of human characteristics to inanimate objects, which is often taken as a characteristic of children's thinking. Preschool children are not yet able to distinguish clearly between properties of objects and characteristic of people because they have recently learned to separate their own actions from those of other people. During the preschool years, many cognitive-developmental changes take place. Before this period, infants cannot differentiate between themselves and their actions in the surroundings. At about 2 years, children are able to do representation, can think about the properties of things without having to act on them directly. This shows the beginning of the first level of the preoperational period. At this level, the child can deal with only one representation, one idea or thought at a time. At the second level of the preoperational period, which begins at about 4 years, children develop the ability to deal mentally with more complex things. During the preschool years the child moves through these two levels, building increasingly complex and sophisticated schemes. The egocentric, complexive, magical thinking of infancy gradually gives way 31 to more logical thinking-perspective taking, a better memory, and an ability to separate oneself mentally from one's immediate environment. Stages of Language Development Prenatal Development Babies do not speak before they are born, yet language learning appears to begin before birth. During the last trimester of prenatal development the foetus can hear its mother’s voice as shown by changes in foetal heart rate and motor activity when the mother is speaking, and this affects its preferences for language after birth in a number of ways. Of course babies do not speak before they are born, yet language learning appears to begin before birth. Shared Attention, Gestures, and Sign Language In the first months after birth, infants focus mostly on their own bodies and on the interaction with the people in their world. At about 6 months, they begin to develop more interest in the objects and events around them. When babies look or point at what they see, adults tend to label what it is for them. Nonverbal “signs” are representations that have meaning, like words. Using signs can reduce frustration for both parent and child. One concern some people have is that babies will rely on these signs and this will delay development of spoken language, 32 but research shows that it is not true. In fact, babies who can show sign, may have a slight advantage in their early spoken language learning. Toddlers’ Development of Words and Sentences Babbling sometimes leads directly to babies’ first words. The sounds they play with while babbling may be the sounds they use for the first words they say. Through interaction, they associate words with familiar objects and people. Growth of Vocabulary At around 2 years of age, word development undergoes a drastic change. After the second year of a child’s life, the vocabulary suddenly expands and that is why it is known as naming explosion, word spurt or vocabulary burst. During this vocabulary expansion, a child learns 10 words a week. This goes on through the preschool, early school, and elementary school years. The vocabulary burst is remarkable in the sense that the children do not get help from word learning but picking up words from the environment. Bilingualism and Bilingual Education Learning to speak a language is a complex, cognitive task, so learning to speak two different languages is even more cognitively complex. Children, who learn two languages simultaneously, reach language milestones approximately as the same age as of the children who are monolingual. Young children learn a second language at a fast rate. There is evidence that target language words are more effectively learned by unknowingly acquiring it, through reading story book or conversing regularly, rather than making a deliberate effort of memorizing the words. The choice between learning new words in real life situations or making a deliberate effort to learn words makes the difference in intentional vocabulary learning or incidental vocabulary learning. Bilingual Acquisition 33 Between three to five years, all children become fully competent in at least one language. This is accepted as totally normal. Even more remarkable are those children who simultaneously acquire proficiency in two, or more languages during the preschool years. It takes the same time frame for monolingual children to learn one language as well as the bilingual children to learn two languages and become good at using them in social and personal surroundings. Bilingual children may learn their languages primarily at home, like monolingual children, or in the daycare, or neighborhood. Bilingual children's exposure to their languages can also differ greatly, as, for example, if the child is learning one language from parents, who each speaks in a different language. Their language exposure can fluctuate greatly over time. The studies and researches by Warwick Elley suggests that young language learners learn new words through interesting books than by doing vocabulary exercises. Children learn new words better in natural contexts and situations. What are the most important things for parents or early childhood educators to know about early childhood bilingualism? There are number of important things to keep in mind:  bilingual acquisition is a common and normal childhood experience  all children are capable of learning two languages in childhood 34  knowing the language of one's parents is an important and essential component of children's cultural identity and sense of belonging  bilingual acquisition is facilitated if children have sustained, rich, and varied experiences in both languages  proficiency in both languages is more likely if children have sustained exposure in the home to the language that is used less extensively in the community; the language that is used more widely will get support outside the home  parents can facilitate bilingual proficiency by using the language they know best and by using it in varied and extensive way. A dramatic accomplishment This is the period of the acquisition of language. In late infancy, children learn to say a few individual words and by paying attention to context, they can also understand some of the language used around them. At about 2 years of age, their ability to use language suddenly increases rapidly. The size of the vocabulary increases and they 35 begin to string words together in short sentences. The ability to represent objects, people and events through language, develops at about the same time as representation in children's imitation, play and other actions. While representation is not required in uttering simple individual words, it is necessary for organizing words into simple statements. The growth of children's vocabulary and their increased ability to use complex sentence structures along with the corresponding growth in their ability to engage in conversation made according to the listener's needs, requires both participation in responsive human interactions and exposure to a rich language environment (Bruner, J. 1983). Most research on language development has focused on how children acquire the rules that govern our use of language. The two types of rules that have been most investigated are pragmatics, rules for communicating in social contexts, and grammatical rules for combining words. Another device is the use of a question as an indirect request. Because of egocentric thought and social inexperience, young children do not fully understand the indirect requests. For children, the simple pragmatic functions of language are often more important than the specific meanings of sentences. When English speaking preschool children meet in small groups with preschool children who speak another language, they may play together for days without seeming to notice their language differences. An English speaking 4 years old walked up to French speaking 3 year old and spoke in English. The 3 year old answered in French and they proceeded to play, acting as if they both understood, taking turns, nodding in agreement, and so forth. This interaction emphasized the similarity of pragmatic rules between languages while the meaning of words is generally obvious from the context and from other nonverbal cues like the tone of voice. Children in the early preoperational period believe only in their own viewpoint, and they think that what interests them interests everyone. This egocentrism leads children to endless self-reporting and a strong feeling that other people know what they themselves know. They frequently conduct a conversation as though it were a 36 monologue, changing the subject without being aware of the listener's response. At about 4 years of age, children begin to master some of the more complex pragmatic rules that were so difficult when they were younger. Children must also learn grammar and the rules for forming words, phrases, and sentences. They must be able to express such states and relations as possession, negation, past action and conditional action. One of the most basic concepts is organization of words into sentences. In order to distinguish one sentence from another, each group of words in a sentence has a certain pitch, and stress, so that listeners can distinguish one sentence from the next. English speakers generally drop the pitch at the end of a statement and raise it at the end of questions. Most children recognize and can infer meaning from intonation patterns sometime in the first year of life. This enormous accomplishment reflects the special adaptation of the human species for acquiring language. Some psycho-linguistic researchers believe that we inherit species-specific strategies, or operating principles, for perceiving speech. These language operating principles are similar to the newborn's rule for visual scanning. In the same way, young children listen to the language in ways that help to discover its meaning. These strategies for perceiving speech make it easier to understand the rules of speech production. Three important operating principles have helped to explain two of the best known characteristic of children's early speech- telegraphic speech and overregulation. These operating principles include paying attention to the endings of words, paying attention to the order of words and word segments, and avoiding exceptions to language rules. Telegraphic speech refers to a child's tendency to use only the two or three most important words to express meaning. For example, a child says; "Mommy rice," rather than "Mommy, I would like to have some rice." The average length of sentences steadily increases during the period from 2 to 6 years. Telegraphic speech in different languages has many differences as well as similarities. Since telegraphic sentences are often ambiguous, interpretation often relies on contextual information. 37 The operating principle of avoiding exceptions to language rules, results in over regularization as children apply a language rule to a word or phrase that does not follow the rule. Statements such as "I goed out and throwed my ball at those gooses" are common from English speaking children at this stage of language development. Children speaking the same language seem to acquire rules in a similar order. Rules that are simple and used often are acquired first followed by an understanding of and an ability to combine more complex rules. Some grammatical forms that are not particularly difficult to understand may enter a child's speech late because they are difficult to hear. Since young children can only listen to language, they often make mistakes due to the way a word or phrase sounds. Preschool children are completely in love with language. They listen to it carefully and chatter away for hours. By the age of six or seven they have acquired and mastered most of the rules for speaking in their native language. This suggests that there is a critical time, or sensitive period for acquiring language that begins at one or two years of age, goes high in the later preschool years, and continues to some degree until 13 to 15 years of age. This special human sensitivity for learning language in the preschool years seems to correspond to certain systematic changes in the brain and in the rest of the nervous system at about this time, which are closely related to speech. The best documented of these changes are called myelogenetic cycles. Each cycle is a period in which myelin forms in a particular system within the brain. There are three myelogenetic cycles in the system that is important to language (Lecours, 1975). The first cycle, which occurs in the primitive brain (the brain stem and the limbic system) starts before birth and ends early in infancy. It seems to be associated with the development of babbling. The second cycle, which begins around birth and continues until 3.5 to 4.5 years of age, takes place in a more advanced part of the brain. This cycle appears to accompany the development of speech in infancy and the early preschool years. The third cycle takes place in the association areas of the cortex of the brain, which play a central role in intelligence. Although myelination of these areas begins at birth, it is not fully completed until age 15 or later. 38 Language develops very efficiently for the majority of children. Parents can help in getting natural language development by providing an environment full of language development opportunities. With young children, for example, one helpful style of interaction is a highly responsive one, in which the adult lets the child decide what to talk about, expands on that topic, works hard to figure out what the child means, suggests new activities, and pays more attention to what the child wants to say than whether it is being said correctly. A good language teacher imparts the role of a cooperative conversational partner rather than taking an explicitly didactic or directive role. Language teaching is most useful to young children when it is presented in the context of their own activities. Older preschool children can learn language and they no longer need to encounter each new language skill within a meaningful context. They can also learn intentionally, benefit from explicit instruction, and use models as sources of learning. At this stage simply responding to the child's interests may not be enough to stimulate optimal language development. Talking about a wide variety of topics, modeling an enriched vocabulary, engaging in talk about talk itself, discussing word meanings, challenging children to explain themselves and to justify their own thinking, setting higher standards for comprehensibility, and explicitly correcting errors: all these are important in the language development of 4, 5, and 6 year old children. Children at this age range are also expected to control certain language- related literacy skills that probably emerge from being read to, from experience in looking at books with adults, and from experience with letters, with pencils and paper, and with observation of adult literacy activities. Parents can organize the environment to provide and encourage the use of pre-literacy learning materials to foster such skills. Stages of language acquisition in children In most cases, children's language development follows a predictable sequence. However, there is a great deal of variation in the age at which children reach a given 39 milestone. Each child's development is usually characterized by gradual acquisition of particular abilities. Thus the correct use of English verbal inflection will emerge over a period of a year or more, starting from a stage where verbal inflections are always left out, and ending in a stage where they are nearly always used correctly. There are also many different ways to characterize the developmental sequence. On the production side, focusing primarily on the unfolding of lexical and syntactic knowledge, it is: Stage Typical age Description Babbling 6-8 months Repetitive CV patterns One-word stage (better one- 9-18 morpheme or one- Single open-class words or word stems months unit) or holophrastic stage 18-24 mini-sentences with simple semantic Two-word stage months relations Telegraphic stage or early multiword Telegraphic sentence structures of 24-30 stage lexical rather than functional or months (better multi- grammatical morphemes morpheme) Grammatical or functional structures Later multiword stage 30+ months start 40 Vocalizations in the first year of life At birth, the infant vocal tract is in some ways more like that of an ape than that of an adult human. In particular, the tip of the velum reaches or overlaps with the tip of the epiglottis. As the infant grows, the tract gradually reshapes itself in the adult pattern. During the first two months of life, infant vocalizations are mainly expressions of discomfort (crying and fussing), along with sounds produced as a by-product of reflexive or vegetative actions like coughing, sucking, swallowing and burping. There are some non-reflexive, non-distress sounds produced with a lowered velum and a closed or nearly closed mouth, giving the impression of a syllabic nasal or a nasalized vowel. During the period from about 2-4 months, infants begin making comfort sounds, in response to a good interaction with a parent or close one. The earliest comfort sounds may be grunts or sighs, with later ones being more vowel-like "coos". The vocal tract is held in a fixed position. Initially comfort sounds are brief and produced in isolation, but later appear in series separated by glottal stops. Laughter appears around 4 months. Between 4-7 months, infants typically engage in vocal play, manipulating pitch (to produce squeals and growls), loudness (producing yells), and also manipulating tract closures to produce friction noises, nasal murmurs. 41 At about seven months, "canonical babbling" appears, where the infants starts making extended sounds that are chopped up rhythmically by oral articulations into syllable- like sequences, opening and closing their jaws, lips and tongue. The range of sounds that are produced are heard as stop-like and glide-like. Fricatives, affricates and liquids are more rarely heard, and clusters are even rarer. Vowels tend to be low and open, at least in the beginning. Repeated sequences are often produced, like bababa or nanana, as well as "variegated" sequences in which the characteristics of the consonant-like articulations are varied. The variegated sequences are initially rare and become more common later on. Both vocal play and babbling are produced more often in interactions with the near ones, but infants also produce them when they are alone. No other animal does anything like babbling. It has often been hypothesized that vocal play and babbling have the function of "practicing" speech-like gestures, helping the infant to gain control of the motor systems involved, and to learn the acoustical consequences of different gestures. One word (holophrastic) stage At about ten months, infants start to utter recognizable words. Some word-like vocalizations that do not correlate well with words in the local language may consistently be used by particular infants to express particular emotional states: one infant is reported to have used to express pleasure, and another is said to have used to express distress or discomfort. For the maximum number of times recognizable words are used in a context that seems to involve naming: dog when the child hits a toy dog , wash while the child washes 42 clothes under running water, car while the child looks out of the window at cars moving on the street below. Perception vs. production Clever experiments have shown that most infants can understand some words at the age of 4-9 months, often even before babbling begins. In fact, the development of phonological abilities begins even earlier. Newborns can distinguish speech from non- speech, and can also distinguish among speech sounds.Within a couple of months of birth, infants can also differentiate speech in their native language from speech in other languages. Early linguistic interaction with mothers, fathers and others at home is almost certainly important in establishing these early abilities, long before the child gives any indication of language abilities. Rate of vocabulary development In the beginning, infants add active vocabulary somewhat gradually. Here are measures of active vocabulary development in two studies. The Nelson study was based on diaries kept by mothers of all of their children's utterances, while the Fenson study is based on asking mothers to check words on a list to indicate which they think their child produces. Nelson 1973 Fenson 1993 Milestone (18 children) (1,789 children) 15 months 13 months 10 words (range 13-19) (range 8-16) 20 months 17 months 50 words (range 14-24) (range 10-24) 186 words 310 words Vocabulary at 24 months (range 28-436) (range 41-668) 43 There is often a spurt of vocabulary acquisition during the second year. Early words are acquired at a rate of 1-3 per week (as measured by production diaries). In many cases, the rate may suddenly increase to 8-10 new words per week, after 40 or so words have been learned. However, some children show a steadier rate of acquisition during these early stages. The rate of vocabulary acquisition definitely does accelerate in the third year and beyond. An estimate average of 10 words a day during pre-school and elementary school years are noticeable. Perception vs. production again Benedict (1979) asked mothers to keep a diary indicating not only what words children produced, but what words they gave as an evidence of understanding. Her results indicate that at the time when children produced 10 words, they were estimated to understand 60 words; and there was an average gap of five months between the time when a child understood 50 words and the time when (s)he produced 50 words. Combining words: the emergence of syntax During the second year, word combinations begin to appear. Novel combinations (where we can be sure that the result is not being treated as a single word) appear sporadically as early as 14 months. At 18 months, 11% of parents say that their child is often combining words, and 46% say that (s) he is sometimes combining words. By 25 months, almost all children are sometimes combining words, but about 20% are still not doing so "often." Early multi-unit utterances In some cases, early multiple-unit utterances can be seen. Children tend to combine two naming words together into one and speak. However, these combinations occur in an order that is appropriate for the language being learned: 1. Doggy bark 2. Jane water (for " Jane wants to drink water”) 3. Hit cat 44 Since the earliest multi-unit utterances are almost always two morphemes long -- two being the first number after one! This period is sometimes called the "two-word stage". Quite soon, however, children begin sometimes producing utterances with more than two elements, and it is not clear that the period in which most utterances have either one or two lexical elements should really be treated as a separate stage. In the early multi-word stage, children who are asked to repeat sentences may simply leave out the determiners, modals and verbal auxiliaries, verbal inflections, etc., and often pronouns as well. Acquisition of grammatical elements and the corresponding structures At about the age of two, children first begin to use grammatical elements. In English, this includes finite auxiliaries ("is", "was"), verbal tense and agreement affixes ("-ed" and '-s'), nominative pronouns ("I", "she"), complementizers ("that", "where"), and determiners ("the", "a"). The process is usually a somewhat gradual one, in which the more telegraphic patterns alternate with adult or adult-like forms. Over a year to a year and a half, sentences get longer, grammatical elements are less often omitted and less often inserted incorrectly, and multiple-clause sentences become a very common fact. Perception vs. production again Several studies have shown that children, who regularly omit grammatical elements in their speech, nevertheless expect these elements in what they hear from adults, in the sense that their sentence comprehension suffers if the grammatical elements are missing or absent. SOCIAL AND EMOTIONAL DEVELOPMENT 45 Social development is a two-sided process in which children become increasingly integrated into the larger social community as distinct individuals. The process of acquiring the standards, values, and knowledge of communities and society is known as socialization. The way in which individual children develop a characteristic sense of themselves and a unique way to think and feel is known as personality formation (Damon, 1983). Socialization which begins as soon as a child is born is especially important during early childhood as the first understanding of the child's community is made. It is a process that requires the active participation of both adults and children. Parents set expectations for children's proper behaviour as well as the rewards or punishments for their conduct. They also select and create the social contexts within which children experience their environments and learn the rules of behaviour. Children are active participants in this process. Their learning depends on their interpretation of their environment and on what they choose to be important. Children need to understand the social categories, roles, rules and expectations of their families and communities in order to function in a social world. Effective socialization assures that if a child comes to consider herself a girl, she will acquire the appropriate behaviour for girls as defined by a particular social group. In order to understand the requirements of this role, however, she must have certain skills and abilities. The particular characteristics of personality for each child are unique because of the particular genes and personal experiences. Some elements of personality are present just after birth as when infants display a particular temperament. Personality is more than individual temperament as it includes the way people conceive of themselves and their characteristic style of interacting with others. Individual personality development and socialization are two sides of the same coin. Social development during the preschool years is closely linked to achievements in cognitive and linguistic skills. The social environment is important during the development of self. One of the most remarkable facts about social development is the extent to which children adopt as necessary the rules defined by their social 46 group. By the time children reach their 6th year, a lot has been learned about the roles they are expected to play and how to behave, how to control anger and aggressive feelings, and how to respect the rights of others. Social Identity Psychologists believe that socialization occurs through identification -- a psychological process that gives a feeling of who one is and who one wants to be. But they disagree about the process by which it is achieved. The four proposed mechanisms that help in our understanding of this basic process are differentiation, affiliation, imitation and social learning, and cognition. According to Sigmund Freud, children recognize that some objects in the external world are like themselves and they therefore "endeavour to mould the ego after one that had been taken as a model.” Identification follows a different course for males and females. Male identification requires differentiation from the mother, while female identification requires continued relation with the mother. Social learning theorists have a different view on how children identify and adopt adult roles. According to them, the process of identification is not driven by inner conflict but occurs through observation and imitation. Behaviour is shaped by the environment and children observe that male and female behaviour is different. Further, children learn that boys and girls are rewarded differently and choose to behave in sex-appropriate behaviours that will lead to rewards. 47 The belief that a child's ability to perceive the world is central to socialization is the basis of the cognitive-developmental approach to sex-role acquisition proposed by Lawrence Kohlberg (1966). In this view the crucial factor in sex-role identification is the child's developing ability to categorize themselves as "boys" or "girls." This process begins at about 2 years of age as children acquire a distinctive sense of self and the beginning of complex concepts. According to this viewpoint, children form a viewpoint about their sex and in spite of the environmental changes; they do not change their perception. There have been some conflicting theories about sex-role identification and psychologists have traced the developing relationship between the earliest signs of sex-typed behaviour and children's earliest concepts of what adults mean when the label "girl" or "boy" is applied. The existing evidence suggests that during the preschool years children gradually develop a well-articulated concept of what it means to be a boy or girl in their culture and their behaviour is shaped by this knowledge. Between 2 and 6 years children are still piecing this conceptual structure together. Both biological and social factors seem to play important roles in promoting both sex-appropriate behaviours and the development of basic sex-role categories themselves. Developmental theorists disagree about the parents’ power to shape the final results, yet, they do agree on two points concerning the children's discovery of social categories and initial mastery of behaviour considering their sex and include: (1) children conduct some kind of mental "matching" operation that allows them to isolate key features that they share with others; (2) later ideas of sex-appropriate behaviour are closely tied to children's ability to categorize, observe, and imitate. Children of 5 or 6 have acquired the idea that they are members of one sex or the other. Children use these abilities to learn other roles and about the possible roles they may need to play in future. Self Regulation 48  While making their basic sense of identity, children also learn which behaviours are considered good and which bad. They are expected not only to learn and adopt the rules of proper behaviour, but also to follow these rules without constant supervision. Piaget proposed that children's beliefs grow out of their experience of the restriction placed on them by powerful adults. From the child's perspective, older people make the rule, compel the children to do so, and decide what is right and wrong. According to Piaget, as children enter middle childhood and begin to interact with their peers other than situations that are directly controlled by adults, the morality of constraint gives way to a more autonomous morality. By the end of infancy children can plan their own actions according to the standards of the society as to which are good and bad. In order to behave according to social standards, children must acquire the capacity to control their own behaviour. Self- control includes both the ability to inhibit action and to carry through actions according to pre established rules even when one does not wish to do so. Preschoolers are popular for their lack of self-control and the necessary need for supervision. Behaviour is simply a direct response to the environment; they are being controlled "from the outside." The direct response to being hit is to be angry and hit back. Children who inhibit the impulse to hit back and seek an alternative response are displaying a degree of self-control. Children who do not understand short-term versus long-term cannot measure "short-term" versus "long-term" gain. During the preschool period, children begin to spend a lot of time interacting with their peers. Through this process children learn to be accepted by their social group. They also show their anger when their goals are challenged; at other times their personal desires will be subordinated for the good of the group. Learning to control 49 aggression and to help others is two of the central processes in preschool social development. Aggression and Prosocial Behaviour Soon after birth, children begin to display both aggression and socially constructive behaviour. The earliest signs of aggression are the angry responses of newborns when their rhythmic sucking is interfered by others. The first signs of helpful social behaviour appear just as early when newborns react to the cries of other babies and start crying themselves. It is believed that this crying is the earliest form of empathy, sharing of another's feelings which is the beginning for a number of helpful or prosocial behaviours. Aggression is a kind of behaviour that is difficult to define and it generally refers to situations where one person commits an action that hurts another. As children mature, two forms of aggression are common, like instrumental aggression and hostile aggression. Instrumental aggression is directed at attaining something desirable, like threatening or hitting another child to get a wanted object. Hostile aggression is more specifically aimed at hurting another, either for revenge or as a way of showing dominance. Observations reveal that by 2 years of age, children are concerned with their ownership rights. Possessing and the possibility of winning are new elements in their interactions. Between 3 and 6 years, the way of expressing aggression goes through several other changes. Physical charge over possessions decrease but the amount of verbal 50 aggression like threats or insults increases. During this stage, hostile aggression that is where a child attempts to hurt another also appears. Generally it is assumed that punishment suppresses children's aggressive behavior. Some child development specialists argue that parents who control children's behavior through physical punishment or threats actually create more aggressive children. Others have suggested that when punishment is used as a means of socialization, it helps to suppress aggression, only when the child identifies strongly with the person who does the punishing and when it is done quite often. If punishment is used inconsistently, it may provoke children to further aggression. Since young children use aggression to gain attention, one strategy is to ignore the aggression or to pay attention to children only when they are engaged in cooperative behaviour. Another strategy is to engage children in a rational discussion making them aware of the feelings of the aggressed. The most successful techniques for teaching self-control of aggression go beyond suppression of aggressive impulses and children are requested to stop their direct attacks and consider other ways to behave. Pro social behaviours like altruism, cooperation, and empathy are quite common among preschool children in addition to aggressive behaviour. A major stimulus for pro social behaviour is empathy, the sharing of another's emotional response. Infants are born with an ability to empathize and this capacity increases with age. Preschool children become skilled at interpreting and responding appropriately to the distress of others. Research seems to suggest that the development of empathy in the preschool period results from the child's increasing command of language and other symbols (Hoffman, 1975). Language allows children to empathize with a wider range of feelings that are more subtly expressed, as well as with people who are not present. Children love to empathize with people whom they have never met by getting information indirectly through stories and pictures. Parents become anxious to encourage pro social behaviour and eventually develop many strategies to promote this goal. Two methods that seem to be helpful include explicit modelling in which adults behave in ways they want the child to imitate, and 51 induction, where they give explanations that appeal to children's pride, their desire to grow up and their concern for others. In reality, strategies to increase pro social behaviour do not happen in keeping away from efforts to decrease aggressive behaviour. A great variety of techniques combine with each other and therefore a number of socialization patterns is created. 52
