Study Notes
Ainsworth Strange Situation
- The Ainsworth Strange Situation is a standardized procedure used to assess the quality of attachment between an infant and caregiver. It is a series of eight episodes that involve separations and reunions between the infant and caregiver.
- The four main attachment styles observed are:
- Secure attachment: Infants feel confident that their needs will be met through the caregiver.
- Insecure-avoidant attachment: Infants avoid or ignore their caregiver.
- Insecure-resistant (ambivalent) attachment: Infants are ambivalent towards their caregiver, demonstrating both clingy and resistant behaviors.
- Disorganized attachment These infants lack a consistent strategy for coping with stress.
Attachment Across Development
- Secure attachment: Infants who are securely attached tend to be more independent, have better social skills, and are more likely to form healthy relationships in adulthood. They develop a sense of trust and confidence in the world.
- Insecure attachment: Children with insecure attachments may struggle with social interactions, have difficulties forming close relationships, and experience anxiety or depression in later life. They may also develop negative self-esteem and have problems with regulating their emotions.
Social Referencing
- Social referencing is the process by which infants use the emotional cues of others to learn how to respond in uncertain situations. It is a critical skill that allows infants to learn about the world around them and to navigate social interactions effectively.
Erikson’s Trust vs. Mistrust and Evolutionary Theories
- Erikson’s theory: emphasizes the importance of parental care in establishing trust and security in infancy. He believed that a child’s earliest relationships with caregivers form the foundation for their future social and emotional development. Trust helps children explore their environment and learn to interact with others.
- Evolutionary theories: Emphasize the adaptive value of attachment, suggesting that it evolved to protect infants from danger.
- Parents and Caregivers: all theories agree that parents play a crucial role in the development of a child’s sense of security and attachment.
Normative Growth
- Children between ages 2 and 6 typically grow about 2 to 3 inches per year. They typically gain 4 to 5 pounds of weight during this time.
Overfeeding
- Adults often overfeed children because:
- Cultural norms and social pressures may encourage overfeeding.
- Parents may mistake hunger cues for other needs, such as attention or boredom.
- Overfeeding may be seen as a way to show love or affection.
Childhood Obesity
- Childhood obesity is more common today than 50 years ago due to factors like:
- Changes in food availability, with more processed and high-calorie foods being readily available.
- Increased screen time and reduced physical activity.
- Genetics and individual differences in metabolism also play a role.
Brain Growth
- Brain growth is rapid between ages 2 and 6. The brain reaches almost 90% of its adult size by age 6.
- Myelination is the process of coating neural fibers with a fatty substance called myelin, increasing the speed and efficiency of neural transmission.
- Myelination is crucial for the development of motor skills, thinking, and language proficiency.
Motor Skills
- Three factors contribute to the development of motor skills:
- Maturation of the nervous system: The brain and nervous system must develop sufficiently to control and coordinate movements.
- Practice: As children practice motor skills, they improve their coordination and efficiency.
- Environment: Children need opportunities to explore and practice their motor skills in a safe and supportive environment.
Childhood Injury
- Injury rates are high in early childhood. This is likely due to children’s impulsivity, lack of coordination, limited understanding of danger, and constant exploration.
Childhood Maltreatment
- Childhood maltreatment was often ignored in the past because it was seen as a private family issue.
- Today, it is understood that childhood maltreatment is a serious social problem with significant consequences for children’s well-being.
- Neglect is considered more harmful than abuse because it is often more pervasive and prolonged. It impacts a child’s physical, emotional, and cognitive development.
Child Maltreatment Statistics
- It is difficult to accurately determine the prevalence of child maltreatment due to:
- The secretive nature of the problem.
- Underreporting by victims and families.
- Differences in definitions and reporting procedures across locations.
Long-Term Consequences of Maltreatment
- Maltreatment in childhood can have long-lasting negative effects on a child’s development, including:
- Emotional and behavioral problems.
- Academic difficulties.
- Health issues.
- Increased risk of engaging in risky behaviors.
- Increased risk of becoming involved in the criminal justice system.
Piaget’s Stages of Cognitive Development
- Sensorimotor stage: The first stage of cognitive development, from birth to approximately 2 years. Infants learn about the world through their senses and motor skills.
- Preoperational stage: The second stage of cognitive development, from approximately 2 to 7 years. Children begin to use language and symbols but their thinking is still limited by egocentrism and a lack of conservation.
- Concrete operational stage: The third stage of cognitive development, from approximately 7 to 11 years. Children begin to understand concrete concepts like conservation and reversibility.
- Formal operational stage: The final stage of cognitive development, which typically begins around age 11 or 12. Individuals gain the ability to think abstractly and hypothetically.
Information Processing Theories
- Information processing theory focuses on the mental processes involved in acquiring, storing, and retrieving information, and how these processes change with development.
Object Permanence
- Object permanence is the understanding that objects continue to exist even when they are out of sight. This is a key milestone in cognitive development, and it develops gradually during the sensorimotor stage.
Critiques of Piaget
- Individual differences: Children may develop cognitive abilities at different rates.
- Underestimation of children’s abilities: Critics argue that Piaget’s tasks underestimated the cognitive abilities of infants and young children.
- Influence of culture: Piaget’s theory may not be universally applicable across cultures.
Visual Cliff
- The visual cliff is a classic experimental setup used to assess depth perception in infants.
- The visual cliff is a table with a clear glass surface over a drop-off.
- Infants who have developed depth perception will refuse to crawl over the glass surface, demonstrating their understanding of the potential danger.
Infant Memory
- Evidence suggests that even young infants possess some degree of memory ability. However, these early memories are often implicit and context-dependent, meaning that they are easier to recall in situations that resemble the original learning environment.
Language Development
- Language development proceeds through a series of stages in early childhood.
- The first year of life is characterized by prelinguistic vocalizations, including cooing, babbling, and the emergence of first words.
- Between 18 months and 2 years, toddlers enter the two-word stage, using simple combinations of words to express meaning.
- By age 3, children are typically able to form longer sentences and engage in basic conversations, understanding grammar and syntax.
Egocentrism and Selfishness
- Egocentrism: A cognitive limitation in which children have difficulty understanding perspectives other than their own. It is a common feature of early childhood.
- Selfishness: A personality trait characterized by a self-centered focus and lack of consideration for others.
Vygotsky and Self-Talk
- Vygotsky believed that self-talk, the process of talking to oneself, is a valuable tool for cognitive development. He saw it as a way for children to regulate their behavior and to internalize language and thought processes.
Bilingualism
- There are advantages to teaching a child two languages:
- Enhanced cognitive skills
- Better language acquisition
- Increased cultural awareness
- More opportunities for communication in a globalized world.
Preschool Education
- There are benefits to preschool education:
- Preparation for academic success
- Social and emotional development
- Higher levels of creativity and problem-solving skills
- Exposure to a stimulating and enriching environment.
Head Start
- Head Start is a federally funded preschool program designed to provide at-risk children with early childhood education and support services.
- Long-term studies demonstrate that Head Start can have positive effects on children’s academic achievement, social-emotional development, and overall well-being.
Heritability
- Heritability refers to the proportion of variation in a trait that can be attributed to genetic factors.
- For example, some physical traits, like height and eye color, have a high heritability, while others are more influenced by environmental factors.
Down Syndrome
- Down syndrome is a genetic disorder caused by an extra copy of chromosome 21.
- Individuals with Down syndrome may experience developmental delays, physical characteristics, and health challenges.
Recessive Conditions
- Recessive conditions require two copies of the recessive allele for the condition to be expressed. It is more common for individuals to be carriers, meaning they have one copy of the recessive allele but do not express the condition themselves.
Sickle Cell Disease
- Sickle cell disease is more prevalent in certain parts of Africa due to the protective effect it provides against malaria. The sickle cell trait confers resistance to malaria, making it more common in regions where malaria is endemic.
Genetic Counselor
- Genetic Counselors are healthcare professionals who provide information and support to individuals and families at risk of genetic disorders.
Prenatal Development
- Germinal Stage(Weeks 1-2): The zygote divides rapidly and implants in the uterine wall.
- Embryonic Stage (Weeks 3-8): All major organs and body systems begin to form.
- Fetal Stage (Weeks 9-40): The fetus grows rapidly in size and weight. Respiratory and digestive systems mature to prepare the fetus for life outside the womb.
Parts of the Embryo
- The neural tube, which develops into the brain and spinal cord, forms first.
Last Three Months of Pregnancy
- In the third trimester, the fetus's lungs mature, and the brain develops rapidly in preparation for birth. The fetus also gains significant weight - about 5 pounds in the last 10 weeks.
APGAR
- The APGAR is a test performed on newborns at 1 and 5 minutes after birth to assess the infant’s overall health. It measures five vital signs: Appearance, Pulse, Grimace, Activity, and Respiration.
- An APGAR score of 7 or higher indicates a healthy newborn.
Prematurity
- A premature infant (preemie) - a baby who is born before 37 weeks of gestation. Preemies can face many health challenges.
- Low birthweight- infants born weighing less than 5 ½ pounds.
- Very low birthweight are infants weighing less than 3 pounds, 5 ounces.
- Extremely low birthweight- infants who weigh under 2 pounds, 3 ounces.
Teratogens
- A teratogen is any agent that can cause birth defects or other developmental problems in a fetus.
- Behavioral teratogens are substances that can damage the developing brain and result in various behavioral and learning disabilities.
Stages of Birth
- Stage 1 (Labor): The cervix dilates and effaces, and contractions become more frequent and intense.
- Stage 2 (Delivery): The baby is pushed through the birth canal.
- Stage 3 (Placenta): The placenta is delivered.
Newborn Social Interactions
- Newborns are capable of social interaction. They demonstrate behaviors like suckling, grasping, and making eye contact, all of which facilitate bonding and social development.
Brazelton Neonatal Behavioral Assessment Scale (NBAS)
- The Brazelton Neonatal Behavioral Assessment Scale (NBAS) is a neurobehavioral assessment used to assess a newborn's reflexes, motor skills, state regulation, and social interactions.
Newborn Reflexes
- Newborn infants exhibit a variety of primitive reflexes that are automatic responses to specific stimuli:
- The rooting reflex helps them find food as they turn their head toward a touch on the cheek.
- The sucking reflex enables them to take in nourishment.
- The grasping reflex is a strong grip when something touches the palm.
- The Moro (startle) reflex is a response to sudden noise or loss of support.
Parent-Infant Bond
- The formation of the parent-infant bond involves a complex interplay of physical, emotional, and social factors.
- Early experiences of close contact and interaction between caregivers and newborns can create a strong foundation for attachment and secure relationships in later life.
Other Important Newborn Issues
- Maternal Depression: is a significant health concern that can impact the emotional well-being of both mother and infant. Signs of depression can include feelings of sadness, anxiety, fatigue, loss of interest in activities and difficulty bonding with the baby.
- Fathers: Fathers play a critical role in the newborn’s development. They provide physical and emotional support, care taking responsibilities, and contribute to the family’s overall well-being.
- Breastfeeding: Benefits for both mother and infant - including improved health outcomes, reduced risk of allergies, and increased bonding.
- Kangaroo Care: Involves skin-to-skin contact between a baby and parent promoting bonding.
Infant Growth and Development
- Infants grow rapidly during the first year of life, both physically and cognitively.
Brain Development in Infancy
- The brain undergoes significant changes during the first year of life through the process of synaptic pruning. -Experience-expectant growth involves brain development that relies on typical experiences for proper development.
- Experience-dependent growth refers to brain development that is shaped by individual experiences.
Stress and Early Development
- Stressful experiences or social deprivation can negatively impact early brain development, leading to disruptions in social, emotional, and cognitive development.
Infant Sensory Abilities
- Infant sensory abilities develop rapidly during the first year of life:
- Sight: Infants can see at birth but their visual acuity is limited. They begin to track moving objects and show a preference for faces. By 12 months, their vision is similar to an adult’s.
- Sound: Infants are highly sensitive to sounds. They show preferences for human voices and recognize familiar sounds.
- Taste: Newborns have a preference for sweet tastes, and they are able to distinguish different flavors.
- Motor Skills: Infants develop their motor skills through a sequence of developmental milestones, such as rolling over, sitting up, crawling, and walking.
Immunizations
- Immunizations protect children from serious diseases. It is crucial to ensure that infants and children receive the recommended immunizations to prevent outbreaks.
Breastfeeding
- Breastfeeding is encouraged until a child is at least one year old.
- Breast milk provides essential nutrients for optimal growth and development.
- Mothers who breastfeed typically return to their pre-pregnancy weight more quickly.
Malnutrition
- Malnutrition, a condition that occurs when the body does not receive enough nutrients to function properly.
- Malnutrition during infancy and early childhood can lead to:
- Stunting:
- Wasting
- Impaired cognitive development.
Infant Emotions
- Infants have basic emotions such as happiness, sadness, anger, and fear that are evident within the first few months of life.
- The second year of life is marked by the emergence of more complex emotions, such as embarrassment, guilt, and shame.
Fear in Infants
- Infants typically develop fears related to separation from primary caregivers, unfamiliar faces, loud noises, and objects.
- These fears are generally considered to be adaptive, as they help infants to stay safe and protect themselves from potential dangers.
Temperament
- Temperament is an individual's characteristic style of behavior that is largely influenced by genetics and early experiences.
- Temperament traits include activity level, emotional intensity, sociability, and effortful control.
- Temperament generally remains stable over time but can be influenced by environmental factors.
Synchrony
- Synchrony is a coordinated, mutual, and often reciprocal pattern of interaction between infants and caregivers.
- It is essential for nurturing healthy attachment, effective communication, and optimal emotional and social development.
Attachment
- Attachment is the emotional bond that develops between an infant and their caregiver.
- Proximity-seeking and contact-maintaining are two key behaviors that demonstrate the importance of attachment to a caregiver.
Attachment Types
- Secure attachment: Babies who are securely attached are confident that their caregiver will be there for them. This bond is fostered through consistent, responsive caregiving.
- Insecure-avoidant attachment: Babies who are insecure-avoidant seem to avoid or ignore their caregiver. This type of attachment can result from inconsistent or unresponsive caregiving.
- Insecure-resistant (ambivalent) attachment: These babies are ambivalent toward their caregiver. They may cling to them but resist their efforts to comfort them. This type of attachment is often associated with inconsistent or unpredictable caregiving.
-
Disorganized attachment: These infants exhibit inconsistent and unpredictable behaviors.
- They may appear confused, frightened, or withdrawn.
- They may engage in contradictory behavior patterns, such as simultaneously seeking and avoiding their caregiver.
Developmental Science
- Developmental science focuses on the interplay between the physical, cognitive, and psychosocial aspects of human development across the lifespan.
- It examines how individuals change and grow over time, exploring factors that influence these changes such as:
- biology
- environment
- culture
Scientific Method
- The scientific method is a systematic approach for acquiring knowledge about the world through observation, experimentation, and analysis.
- It consists of five key steps:
- Formulate a question or hypothesis.
- Gather evidence through observation or experimentation.
- Analyze the data.
- Draw conclusions.
- Communicate the findings.
- It consists of five key steps:
Nature vs. Nurture
- The nature vs. nurture debate is an enduring question in developmental science that explores the relative contributions of genetics and the environment to human development.
- Scientific consensus today is that both nature and nurture influence all aspects of development, in a dynamic and complex interplay.
Genetics and Epigenetics
- Genetics refers to the study of genes, which are the basic units of heredity.
- Epigenetics focuses on changes in gene expression that occur without altering the underlying DNA sequence.
- Epigenetic modifications can be influenced by environmental factors and can affect an individual's susceptibility to certain diseases and conditions.
Differential Susceptibility
- Differential susceptibility recognizes that individuals may vary in their sensitivity to environmental influences.
- Some individuals may be more vulnerable to negative experiences, while others are more resilient.
Continuity and Discontinuity
- Continuity: Development is gradual and cumulative, characterized by continuous, incremental changes.
- Discontinuity: Development involves distinct stages with qualitative differences.
Critical and Sensitive Periods
- Critical Period: A specific time during development when certain experiences must occur for normal development to proceed.
- Sensitive Period: A time during development when a particular experience has a strong influence but is not essential for development.
Social Contexts
- Social contexts encompass the various social and cultural environments that influence human development.
Cohorts and Age Groups
- Cohort: A group of people who are born around the same time and share similar experiences.
- Age Group: People who share similar ages.
Plasticity
- Plasticity refers to the capacity for change and adaptation throughout the lifespan.
- The brain remains malleable which allows for the acquisition of new skills and experiences, and adaptations to new environments throughout life.
Scientific Methods in Developmental Science
- Developmental scientists employ a variety of methods to study human development.
- Each method has distinct advantages and disadvantages.
- Choosing the appropriate method depends on the research question and the type of data being collected.
- Observations: Involve watching and recording behavior in a natural setting.
- Experimental Studies: Seek to establish cause-and-effect relationships by manipulating variables. A key feature is random assignment to experimental groups to control for confounding variables.
- Surveys: Involve gathering information from individuals using questionnaires or interviews.
- Cross-Sectional Research: Compares groups of individuals at different ages at a single point in time.
- Longitudinal Research: Follows the same group of individuals over time to observe developmental changes.
- Cross-Sequential Research: Combines aspects of both cross-sectional and longitudinal designs.
- Correlational Research: Examines the relationships between two or more variables.
- Quantitative Research: Collects numerical data to quantify and analyze phenomena.
- Qualitative Research: Focuses on understanding the complexities of social experiences, using methods like interviews, focus groups and observation to gather descriptive, nuanced, and rich data.
IRB
- An Institutional Review Board (IRB) is a panel of experts that reviews research proposals to ensure their ethical conduct.
- Ethical considerations in development science involve safeguarding the welfare of participants, ensuring informed consent, and protecting privacy and confidentiality.
Theories of Development
- Theories provide a framework for understanding and explaining human development and guide research in the field.
Functions of Theories
- Describe: Provide a framework for organizing and explaining observations.
- Explain: Identify causal factors that contribute to development.
- Predict: Anticipate the course of development.
Grand Theories
- Grand theories provide comprehensive perspectives on human development.
-
Psychoanalytic Theories:
- Freud: Focused on the unconscious mind, psychosexual stages (oral, anal, phallic, latency, genital).
- Erikson: Expanded upon Freud’s work, focusing on psychosocial development (trust vs mistrust, autonomy vs shame and doubt, initiative vs guilt, industry vs inferiority, identity vs role confusion).
-
Behaviorism:
- Skinner: Emphasized learning through reinforcement.
- Bandura: Developed the theory of social learning, emphasizing observational learning, modeling.
-
Cognitive Theories:
- Piaget: Proposed a series of stages of cognitive development, including sensorimotor, preoperational, concrete operational, and formal operational.
- Vygotsky: Focused on the role of culture and social interactions in cognitive development, emphasizing the zone of proximal development (ZPD).
- Information Processing: Focuses on the mental processes involved in acquiring, storing, and retrieving information.
Neuroscience
- Advances in neuroscience have provided insights into the biological mechanisms underlying development.
- Neuroscience has enabled researchers to observe brain activity and development in ways that were not possible for earlier theorists.
Newer Theories
- More recent theories are influenced by cultural diversity and multidisciplinary perspectives, aiming for broader, universal applications.
- Sociocultural Theories: Place emphasis on the role of culture, social interactions, and social and cultural beliefs in shaping development.
- Evolutionary Theories: Apply evolutionary principles to understand human behavior and development.
Criticisms of Theories
- Each grand theory has its weaknesses and limitations and is subject to critiques.
Eclectic Approach
- Most developmentalists adopt an eclectic approach to theories, meaning they integrate ideas from various theories to provide a more comprehensive understanding of development.
Chromosomes and Genes
- Humans have 46 chromosomes, organized into 23 pairs.
- Each chromosome contains thousands of genes which are units of heredity that determine characteristics and traits.
Alleles
- Alleles are alternative forms of a gene.
Microbiome
- The microbiome refers to the trillions of microorganisms that live in and on the human body, including the gut, skin, and mouth.
- The microbiome plays a role in health and development, influencing immune function, digestion, and overall well-being.
Zygote Uniqueness
- Each zygote (fertilized egg) is genetically unique due to the random assortment of chromosomes during meiosis.
- A baby’s sex is determined by the father’s sperm:
- An X chromosome from the sperm results in a girl (XX).
- A Y chromosome from the sperm results in a boy (XY).
Stem Cells
- Stem cells are undifferentiated cells that have the potential to develop into specialized cells of various types.
In Vitro Fertilization (IVF)
- IVF: Sperm and egg are combined in a laboratory dish.
- Traditional Pregnancy: The egg is fertilized naturally within the woman's body.
CRISPR
- CRISPR-Cas9 is a gene-editing technology that allows scientists to precisely alter DNA sequences.
- It is a revolutionary tool for gene editing and genetic research but its use for human embryos is controversial due to ethical concerns.
Monozygotic and Dizygotic Twins
- Monozygotic (identical) twins develop from a single fertilized egg that splits into two embryos.
- Dizygotic (fraternal) twins develop from two separate eggs that are fertilized by two different sperm cells.
Inheritance
- Additive inheritance: A trait is influenced by multiple genes.
-
Dominant-recessive Inheritance: A trait is determined by a single pair of alleles.
- The dominant allele (like brown hair) is expressed even if only one copy is present.
- The recessive allele (like blonde hair) is only expressed when two copies are present (one from each parent).
Emotional Development in Early Childhood
- As children grow, their emotions become more complex and nuanced.
- Emotion regulation is the ability to manage and control one’s emotions. It involves:
- Identifying and understanding emotions
- Expressing emotions appropriately
- Responding to emotions effectively
- Regulating the intensity and duration of emotional responses
Effortful Control
- Effortful Control is an aspect of temperament that involves the ability to inhibit impulses, regulate emotions, and focus attention.
- It is linked to the development of self-control, resilience, and social skills.
Attachment and Parents’ Roles
- Attachment: The bond between parents and children continues to evolve and deepen throughout early childhood as children develop increasingly complex emotional and social abilities.
- Parents’ Roles: Parents continue to provide a secure base of support for their children's exploration and development.
Parenting Styles
- Parenting styles refer to the patterns of behavior that parents use to raise their children.
- Baumrind described four primary parenting styles:
- Authoritative: High warmth and high structure. Warm and loving parents who provide clear boundaries and rules for behavior.
- Authoritarian: High structure and low warmth. Parents who impose strict rules and expectations, often demanding obedience without explanation.
- Permissive: High warmth and low structure. Parents who are indulgent and lenient, setting few limits on behavior.
- Uninvolved: Low warmth and low structure. Parents who are indifferent to their children’s needs.
- Baumrind's research suggests that authoritative parenting is the most effective style. It promotes cooperation and self-reliance. However, Baumrind’s research had limitations in its cultural bias.
Culture and Parenting Styles
- Parenting styles vary across cultures, and what is considered effective in one culture may not be effective in another.
Corporal Punishment
- Corporal punishment (physical punishment) is widely discouraged by child development experts as it is associated with negative consequences, including:
- Child aggression and behavioral problems.
- Mental health issues
- Abuse and neglect.
Induction
- Induction is a form of discipline in which parents explain the reasons behind rules and consequences for misbehavior.
- This can be an effective form of discipline when used in a supportive and respectful manner.
Screen Time
- Experts suggest that screen time for children should be limited, particularly in early childhood.
- Excessive screen time can be detrimental to development and can be associated with:
- Physical health issues like obesity, sleep problems, and eye strain.
- Cognitive difficulties.
- Social-emotional problems.
- Children learn by watching others and imitating their behavior. They can also learn from the content of screens.
- However, it is essential to:
- Ensure that screen time is age-appropriate,
- Encourage active play and other enriching activities.
- Promote media literacy.
Empathy and Antipathy
- Empathy is the ability to understand and share the feelings of others.
- Antipathy is a feeling of dislike or aversion toward another.
- Children develop both empathy and antipathy as they interact with their peers.
Prosocial Behavior
- Prosocial behavior is any act that is intended to benefit another person.
- Empathy is thought to play a crucial role in motivating prosocial behavior.
Childhood Health Habits
- Childhood health habits, such as diet and exercise, can have lasting effects on adult health.
- Healthy habits established in childhood contribute to a lower risk of chronic diseases in adulthood.
Obesity Risks
- Childhood obesity increases the risk of:
- Type 2 diabetes.
- Heart disease.
- Some types of cancer.
- Sleep apnea.
- Social and emotional problems.
Intelligence Tests
- Intelligence tests measure cognitive abilities, such as verbal comprehension, reasoning, and problem-solving.
- They are standardized tests that allow for comparisons of individual scores to normative data.
Flynn Effect
- The Flynn effect refers to the observed increase in IQ test scores over time, suggesting that intelligence has been increasing across generations.
- Possible explanations:
- Improvements in nutrition, healthcare, and education.
- Increased exposure to complex information and technology.
Brain Scans and Intelligence Tests
- While brain scans can provide valuable information about brain structure and function, they are not typically used as a substitute for traditional intelligence tests.
- Brain scans primarily highlight areas of the brain that are activated during cognitive tasks, but they don’t always provide a complete picture of cognitive ability.
Cognition in Middle Childhood
- Piaget described middle childhood as the concrete operational stage.
- Children develop the ability to:
- Think logically about concrete concepts.
- Understand conservation.
- Grasp reversibility.
- Perform mental operations.
Language, Memory, and School
-
Language: Children continue to refine their language skills in middle childhood, expanding their vocabulary, understanding complex grammar, and mastering advanced communication skills.
- Reading and Writing: Children are taught reading and writing, further developing their language abilities.
-
Memory: Working memory, the ability to retain information briefly and actively use it, improves significantly during middle childhood.
- Children become better at strategies for remembering information, such as rehearsal and organization.
- School: Formal schooling plays a significant role in the cognitive development of children in middle childhood.
Social Comparison
- Social comparison is the process of comparing oneself to others to assess abilities and social standing.
- It becomes more prominent in middle childhood as children develop a more refined understanding of social roles and expectations, and their sense of self-worth.
Resilience
- Resilience is the ability to adapt well in the face of adversity and stress.
- Factors contributing to resilience:
- A supportive and caring family.
- Secure attachment to caregivers
- Positive social relationships.
- Good coping skills.
- Sense of personal competence.
