    Study Notes

    Play and Development

    • Infants' play is encouraged by mothers to perform at or above their previous level, promoting further development.
    • Peers are better at sustaining attention from infants in unstructured, physically active play.
    • Mother-infant play serves a teaching function, preparing infants for future communication and stimulating their interest in objects and the environment.

    Cognitive Development

    • Play is essential for the acquisition of information and skills, creative thinking, and representational abilities.
    • Mothers' active participation in collaborative play raises the level of expression of symbolic representation in their children's play.
    • Infants use imitation to initiate pretend play with siblings, but not with mothers.

    Social Understanding

    • Play helps infants develop social understanding, including conveying their own feelings and seeking understanding of others' thoughts and feelings.
    • Secure mother-infant relationships shape social competence in children up to 9 years old.
    • Pretend play helps infants develop understanding of others' feeling states.

    Functions of Play

    • Play helps infants regulate arousal and express emotions.
    • Mothers are better at supporting infants' ability to represent and resolve conflicts and traumas through play than peers.
    • Play is associated with attention span and persistence in structured/unstructured tasks.

    Language Development

    • Mother-child play facilitates the use of more complex language than play with siblings or peers.
    • Adults continue to facilitate language development through responsive engagement with toddlers during collaborative play.

    Social Development

    • Early studies of social development demonstrate that social networks are important for infant development.
    • Wolf and Wolff's study (1947) showed that maternal absence leads to depression in infants.

    Attentional and Cognitive Development

    • William James' study (1890) showed that infants are drawn to stimuli due to interest and association (active attention).
    • Robert Fantz's study (1958, 1964) showed that infants have visual perception capabilities.

    Emotional Development

    • Darwin's study (1872) showed that infants exhibit primary emotions (happy, disgust, sad, fear, anger, surprise) and self-conscious emotions.
    • Lewis and Michalson's study (1983) demonstrated self-awareness in infants using the "rouge test".

    Research Methods

    • Naturalistic observation, standardized developmental tests, and interviews are used to study infant development.
    • Habituation, preference paradigm, and operant conditioning are used to assess different domains of development.

    Imitation and Social Functioning

    • Imitation learning is used to assess social functioning in infants.
    • Naturalistic parent-infant interactions and violation of expectation of behavior are used to study social development.

    Socio-Emotional Behavior

    • The "strange situation" paradigm is used to assess infant attachment to caregivers.
    • Social referencing is used to study how infants learn to interact with others.

    Stress Response

    • Behavioral stress reactivity and regulation are measured in infants using physiological responses (hormone levels, heart rate changes).
    • The "still-face procedure" is used to assess infant response to an unresponsive social partner.### Social Development

    "Contagious" Behaviours

    • Newborns cry when they hear another newborn's cry, demonstrating an empathetic response.
    • By 2 years, toddlers exhibit empathy and can place themselves in another person's role.

    Social Nexus

    • Infants are born into a social network of people and activities that provide for their needs.
    • This social network consists of:
      • Family members who share a genetic pool.
      • Friends and lovers who influence and are influenced by the child.
      • Cultural background that forms the environment for these interactions.

    Biological Functions through Social Interactions

    • Social interactions influence the development of biological functions, such as:
      • Sleep-wake cycles.
      • Organizational processes.

    Developmental Milestones

    • 12 weeks: Infants can discriminate between social sounds (/pa/ and /ba/).
    • 9 months: Infants have some understanding of themselves.
    • 1-3 months: Infants understand the intermodal connection between people's faces and voices.
    • 5 weeks: Infants interact differentially with familiar persons vs. strangers.
    • 7 months: Infants demonstrate discrimination of emotional expressions.
    • 3-4 months: Infants respond differently to children vs. adults.
    • 6-8 months: Infants show differential fear responses to people based on gender and age.

    People in the Infant's Life

    • Mothers:
      • Freud's psychoanalysis: the mother-infant relationship is the primary social bond.
      • Bowlby's attachment theory: the mother-infant relationship is unique and establishes a model for later social relationships.
    • Fathers:
      • Similar to mothers in terms of care and interaction patterns.
      • More likely to engage in physical playful activities.
    • Siblings:
      • Relationships involve competition, rivalry, and even hate, but also have positive aspects.
      • Siblings can affect each other's behaviors and views of themselves.
      • Older siblings tend to be more attached to younger siblings.

    The Social Matrix

    • A model to describe how multiple people and needs interact.
    • Intersects caregiving, play, protection, nurturance, education, etc. with mother, father, grandparents, siblings, and other family members.

    Attachment Styles

    • The Strange Situation: a method to understand attachment styles.
    • Secure attachment: seeking contact with mother during reunion.
    • Insecure attachment: ambivalent, avoidant, or disorganized behaviors.
    • Factors influencing attachment styles: infant temperament, sociability, and type of mother-infant interaction, as well as genetic and environmental factors.

    Visual Perception

    Basic Visual Abilities

    • Vision is the least developed sense at birth.
    • Visual acuity improves significantly by 6 months.
    • Sensitivity to variations in contrast, color vision, and depth perception develop rapidly within the first 6 months.

    An Organized Visual World

    • Size constancy is an organizing feature of perception present at birth.
    • Newborns can imitate facial expressions soon after birth.
    • Functional mirror neural system at birth.

    Eye-Head Control

    • Eye tracking shows that looking is an active motor action.
    • Looking helps infants gain a sense of agency and self.
    • Still-face experiments: infants become distressed when a mother responds to their looking and facial interactions with a still face.

    Manual Skills

    • Many fetus and infant movements are spontaneous and aimless.
    • Spontaneous arm movements persist in high frequency until 1 year.
    • Reaching is intertwined with the development of postural control.
    • Development of reaching and grasping: 4-12 months.

    The Infant's World of Objects

    • ~2 months: Infants realize that partly occluded objects are whole.
    • ~5-6 months: Infants realize that 2 objects touching are separate objects.
    • 6-8 months: Infants have learned about structural support and gravity.

    Posture and Balance

    • Development of vestibular system and kinesthetic feedback begins in the womb.

    Locomotion

    • Locomotor development is not a series of orderly stages.

    • Experience better predicts locomotive progress than age or body dimension.

    • Normal age range for walking onset: 11-15 months.

    • Locomotive experience is not forced; infants start and stop at will, and crawling and walking steps are highly variable.### Locomotion and Development

    • Infants almost never automatically or immediately learn from falling; one-trial learning increases with age

    • Locomotion is a new means-end problem-solving process

    • Infants who walk take into consideration the presence or absence of a handrail and the width of a bridge when attempting to cross it (or not cross it)

    Perception Theories

    • Early theories emphasized an empiricist view of perception, suggesting that infants perceive very poorly and experience is vital for the development of the senses
    • Research in the last 50 years has shown that the nativist view should be combined with the empiricist view, as perceptual development is present at a surprisingly early age

    Touch and Sensitivity

    • Touch is the first sense to develop in the womb
    • Even newborns can discriminate between nipple texture and detect weight change in objects

    Temperature

    • Newborns can differentiate between cold and warm temperatures through mouthing or handling objects (cold/warm nipples and water)

    Pain

    • Neural pathways for pain are present 26 weeks from conception
    • Pain can be measured in infants through facial expressions, heart rate, and crying
    • Pain can be relieved by soothing stimuli, similar to adults
    • Pain develops more strongly as the infant ages

    Taste

    • Fetuses can discriminate between sweet and noxious
    • Amniotic fluid contains different tastes and provides the fetus with this sense experience
    • Newborns can discriminate between sweet, sour, salty, and bitter, evident in their facial expressions
    • At birth, the infant has food preferences
    • Birth-3 months: infants become more active and accepting of new tastes
    • In the first year, the infant will suck any suckable object, including food
    • Hatred of foods doesn't develop until after 2 years
    • Early infancy = intrinsically hunger-driven, later infancy = replaced by extrinsic factors (meal times and appropriate foods for certain times of the day)

    Smell

    • 9-10 weeks after conception: the fetus breathes in and exhales amniotic fluid, giving the fetus experience with odors
    • At birth, the sense of smell is fully developed
    • Newborns show clear odor preferences and aversions through facial expressions
    • Infants can discriminate between subtle smells through habituation procedures

    Hearing and Auditory Abilities

    • Infants can hear low frequencies similar to the ability of adults
    • Newborns can localize sounds and turn their head in the direction of a sound even in a room of complete darkness
    • Newborn babies have preferences for their mothers' voice over a strange woman's voice
    • This preference begins in the womb
    • Newborn babies showed a preference for stories read to them when they were in the womb
    • Infants prefer baby-directed speech or motherese (baby talk)
    • Newborn babies responded more to happy speech patterns than sad or angry
    • Newborn babies preferred speech patterns in their native languages that they would've been exposed to in the womb
    • Speech and language perception begin in the womb
    • Infants are born with the ability to discriminate between sounds in all of the world's languages
    • This ability diminishes around the 1-year mark and babies become "native listeners"

    Eye and Head Control

    • Looking is an active, performatory action system that infants use to respond to and initiate changes in their environment
    • Looking helps infants gain a sense of agency, a distinct self that can affect the environment around them
    • Still-face experiments: infants become distressed when a mother responds to their looking and facial interactions with a still face
    • At first, looking is opportunistic for infants because they lack the strength to lift their heads or coordination to turn their heads with their eyes

    Manual Skills

    • Many fetus and infant "movements" are really spontaneous, aimless movements (kicking in the womb, reaching) with no intent to exert change on the environment
    • Spontaneous motor movement begins at 6 weeks gestation
    • Manual exploration begins in the womb (touching umbilical cord, uterine wall, fetus's own face)
    • Prenatal-1 year: spontaneous arm movements persist in high frequency (arm flailing, waving fingers, rotating arms)
    • Spontaneous manual activity can become goal-oriented; infants shown a slideshow moved from neutral facial expressions during arm flailing to joyful expressions during flailing
