  1. Infancy & Childhood Physical & Social Development

  2. The Beginnings of Life: The Newborn

  3. Infant Abilities • Infants are born with immature visual system • can detect movement and large objects • Other senses function well on day 1 • will orient to sounds • turn away from unpleasant odors • prefer sweet to sour tastes • Senses are keenly attuned to people, helping the infant quickly learn to differentiate between the mother and other humans. • Born with a number of reflex behaviors

  4. Infant Reflexes • Reflex is an automatic, unlearned response • Rooting—turning the head and opening the mouth in the direction of a touch on the cheek. Child is looking for nourishment. • Sucking—sucking rhythmically in response to oral stimulation • Grasping—curling the fingers around an object • Babinski—fanning and curling toes when foot is stroked • Moro—throwing the arms out, arching the back and bringing the arms together as if to hold onto something (in response to loud noise or sudden change in position of the head)

  5. Physical Development in Infancy and Childhood

  6. Infant, Toddler, Child • Infant: First year • Toddler: From about 1 year to 3 years of age • Child: Span between toddler and teen

  7. Infancy and Childhood: The Developing Brain

  8. Neural Development • At birth, the newborn’s brain is 25% of its adult weight; its birth weight, by contrast, is 5% of its eventual adult weight • By the end of infancy a baby’s brain will be 75% of its adult weight but their body and height will be about 20% • Newborns enter the world with an estimated 100 billion neurons. After birth, the brain continues to develop rapidly. • The number of dendrites increases dramatically during the first two years of life. • The axons of many neurons acquire myelin, the white, fatty covering that increases a neuron’s communication speed.

  9. Neural Development

  10. Pruning Synaptic Connections • By age 6, the child’s brain is about 95 percent of its adult size • Although overall brain size doesn’t change during childhood and adolescence, dramatic changes in the number of interconnections occur • Unused dendrites, synaptic connections, and neurons are discarded

  11. Infancy and Childhood: Motor Development

  12. Maturation • Biological growth processes that enable orderly changes in behavior

  13. Motor Development • Includes all physical skills and muscular coordination • The basic sequence of motor skill development during infancy is universal, but the average ages can be a little deceptive. • Each infant has his or her own genetically programmed timetable of physical maturation and developmental readiness to master different motor skills.

  14. Motor Development

  15. Social and Personality Development

  16. Temperament • A person’s characteristic emotional reactivity and intensity • A child might be: • An “easy” or “slow to warm” or “difficult” baby • Temperament shown in infancy appears to carry through a person’s life. • Temperament has a genetic and biological basis, but that environmental experiences can modify a child’s basic temperament.

  17. Temperament • Easy—adaptable, positive mood, regular habits • Slow to warm up—low activity, somewhat slow to adapt, generally withdraw from new situations • Difficult—intense emotions, irritable, cry frequently • Average—unable to classify (1/3 of all children)

  18. Infant Attachment Intense emotional bond between infant and caregiver (mother)

  19. Attachment Theory • An infant’s ability to thrive physically and psychologically depends in part on the quality of attachment. • Infants can form multiple attachments.

  20. Forms of Attachment • Securely attached—explores the room when mother is present, becomes upset and explores less when mother is not present, shows pleasure when mother returns

  21. Forms of Attachment • Insecure Attachment - become extremely distressed when the mother leaves the room and, when reunited, are hard to soothe 2 Types of Insecure Attachment: • Avoidantly attached—a form of insecure attachment in which child avoids mother and acts coldly to her • Anxious resistant attachment—a form of insecure attachment where the child remains close to mother and remains distressed despite her attempts to comfort

  22. 1913-1989 Ainsworth’s Strange Situation • Mother-child dyads were observed in a playroom under four conditions: • initial mother-child interaction • mother leaves infant alone in playroom • friendly stranger enters playroom • mother returns and greets child • Study done with infants between 1 and 2 years old

  23. Effects of Attachment • Secure attachment predicts social competence. • Deprivation of attachment is linked to negative outcome. • A responsive environment helps most infants recover from attachment disruption.

  24. Attachment

  25. Stranger Anxiety • The fear of strangers an infant displays around 8 months of age

  26. Attachment:Harry Harlow’s Monkey Experiments

  27. Attachment • An emotional tie with another person resulting in seeking closeness • Children develop strong attachments to their parents and caregivers. • Body contact, familiarity, and responsiveness all contribute to attachment.

  28. Harlow’s Study of Attachment • Infant rhesus monkeys were placed with two surrogate mothers, one made of wire and one covered with soft cloth • Milk-producing nipple was attached to either the wire or the cloth mother • Attachment was based on “contact comfort” rather than feeding

  29. 1905-1981 Harlow’s Monkeys

  30. Harry Harlow • The monkeys spent most of their time by the cloth mother.

  32. Familiarity & Imprinting in Animals

  33. Familiarity • Sense of contentment with that which is already known • Infants are familiar with their parents and caregivers.

  34. Imprinting and Critical Period • A process by which certain animals, early in life, form attachments • The imprinted behavior develops within a critical period--an optimal period when the organism’s exposure to certain stimuli produce the imprinted behavior. • Konrad Lorenz studied imprinting.

  35. Konrad Lorenz • Studied imprinted behaviors • Goslings are imprinted to follow the first large moving object they see.

  37. Raising Psychologically Healthy Children Parenting Styles

  38. Responsiveness • Responsive parents are aware of what their children are doing. • Unresponsive parents ignore their children--helping only when they want to.

  39. Baumrind’s Parenting Styles • Authoritarian—value obedience and use a high degree of power assertion • Authoritative—less concerned with obedience, greater use of induction • Permissive—most tolerant, least likely to use discipline • Neglectful—completely uninvolved

  40. Basic Parenting Styles • Parents with an authoritarian parenting style are demanding and unresponsive toward their children’s needs and wishes • Parents with a permissive parenting style may be permissive-indulgent (extremely tolerant, not demanding, and responsive to their children) or permissive-indifferent (extremely tolerant, not demanding, and not responsive to their children). • Parents with an authoritative parenting style set clear standards for their children’s behavior but are also responsive to their children’s needs and wishes

  41. Authoritarian Parenting • Low in warmth • Discipline is strict and sometimes physical. • Communication high from parent to child and low from child to parent • Maturity expectations are high.

  42. Permissive Parenting • High in warmth but rarely discipline • Communication is low from parent to child but high from child to parent. • Expectations of maturity are low.

  43. Authoritative Parenting • High in warmth with moderate discipline • High in communication and negotiating • Parents set and explain rules. • Maturity expectations are moderate.

  44. Effects on Children • Children of authoritarian parents are likely to be moody, unhappy, fearful, withdrawn, unspontaneous, and irritable; this style promotes resentment and rebellion. • Children of permissive parents tend to be more immature, impulsive, and aggressive, and they may never learn self-control • Children of authoritative parents tend to be cheerful, socially competent, energetic, and friendly. They show high levels of self-esteem, self-reliance, and self-control

  45. Suggestions for Being an Authoritative Parent • Let your children know that you love them. • Listen to your children. • Use induction to teach as you discipline. • Work with your child’s temperamental qualities. • Understand your child’s age-related cognitive abilities and limitations. • Don’t expect perfection, and learn to go with the flow.
