8 The Remarkable Newborn Ways to Study the Abilities of Newborns
Infancy and Childhood The Remarkable Newborn Ways to Study the Abilities of Newborns 4/15/2017 Habituation The tendency for attention to a stimulus to wane over time (often used to determine whether an infant has “learned” a stimulus Recovery Following habituation to one stimulus, the tendency for a second stimulus to arouse new interest (often used to test whether infants can discriminate between stimuli) Section outline Psychology, 4/e by Saul Kassin ©2004 Prentice Hall ©2001 Prentice Hall

9 The Remarkable Newborn Reflexes
Grasping Reflex In infants, an automatic tendency to grasp an object that stimulates the palm Rooting Reflex In response to contact on the cheek, an infant’s tendency to turn toward the stimulus and open its mouth Psychology, 4/e by Saul Kassin ©2004 Prentice Hall

10 Psychology, 4/e by Saul Kassin ©2004 Prentice Hall
Infancy and Childhood 4/15/2017 The Remarkable Newborn Sensory Capacities Visual Preferences in Newborns Infants spend more time looking at patterns than solids. Infants spend the most time looking at a drawing of a human face. Is this just preference for complexity or an adaptation? Figure from: Kassin, S. (2001). Psychology, third edition.

11 Psychology, 4/e by Saul Kassin ©2004 Prentice Hall
Infancy and Childhood 4/15/2017 The Remarkable Newborn Sensory Capacities Newborn Orientation to the Face Infants were shown a blank shape, a face, or scrambled facial features. The face and scrambled face have same complexity. Infants looked more intensely at the actual face. Figure from: Kassin, S. (2001). Psychology, third edition. Upper Saddle River, NJ: Prentice Hall.

13 Psychology, 4/e by Saul Kassin ©2004 Prentice Hall
Infancy and Childhood 4/15/2017 The Remarkable Newborn Sensitivity to Number Can Infants Add and Subtract? Infants saw a sequence of events that illustrated addition or subtraction. Then they saw a correct or incorrect outcome (2-1=2, for example). The infant looked longer at outcomes that were incorrect. Figure 10.9 from: Kassin, S. (2001). Psychology, third edition.

Preconventional Level Morality judged in terms of reward and punishment Conventional Level Morality judged in terms of social order and approval Postconventional Level Morality judged in terms of abstract principles, like equality and justice Psychology, 4/e by Saul Kassin ©2004 Prentice Hall ©2001 Prentice Hall

29 Adolescence Cognitive Development Kohlberg’s Levels of Moral Reasoning
Infancy and Childhood 4/15/2017 Adolescence Cognitive Development Kohlberg’s Levels of Moral Reasoning Most 7-10 year olds are reasoning at the preconventional level. Most year olds are reasoning at the conventional level. Few participants show reasoning indicative of the postconventional level. Figure 11-6 from: Kassin, S. (2001). Psychology, third edition.

30 Adolescence Cognitive Development Criticisms of Kohlberg’s Theory
Infancy and Childhood 4/15/2017 Adolescence Cognitive Development Criticisms of Kohlberg’s Theory Cultural Bias Some cultural differences are not reflected in this theory. Gender Bias Empirical support for this claim is weak. Connection between moral reasoning and moral behavior is often indirect. Psychology, 4/e by Saul Kassin ©2004 Prentice Hall ©2001 Prentice Hall

31 Adolescence Social and Personal Development Adolescent Disengagement
Infancy and Childhood 4/15/2017 Adolescence Social and Personal Development Adolescent Disengagement The proportion of time spent with the family decreases almost 3% per year This decline was not found for time spent alone with parents Identity Crisis An adolescent’s struggle to establish a personal identity, or self-concept Figure 11-8 from: Kassin, S.

32 Adolescence Social and Personal Development
Infancy and Childhood 4/15/2017 Adolescence Social and Personal Development Patterns of Adolescent “Transformation”Within the Family Adolescents in the 7th and 8th grades felt worse while with their family. Boys feel better after 8th grade and feel the best in 9th and 10th grades. Girls continue to feel bad until the 10th grade. Figure 11-9 from: Kassin, S. (2001). Psychology, third edition.

33 Adolescence Social and Personal Development
Peer Influences Adolescent relationships are intimate. Adolescents begin to discover friendships with other-sex peers. Conformity rises steadily with age, peaks in ninth grade, and then declines. Psychology, 4/e by Saul Kassin ©2004 Prentice Hall

34 Adolescence Social and Personal Development
Sexuality Whether teens act on sexual impulses depends on social factors. Adolescents who engage in sexual behavior with others are not necessarily informed about health risks and contraception . Adolescent sexual behavior may be due to attempts to be more like an adult or as way to rebel. Psychology, 4/e by Saul Kassin ©2004 Prentice Hall

35 Adolescence Adolescence and Mental Health
Infancy and Childhood 4/15/2017 Adolescence Adolescence and Mental Health The stereotypic images of adolescents are: Mood swings, identity crises, anxiety, rebelliousness, depression, drug use, and suicide Three perceived sources of difficulty in adolescence are: Conflict with parents, risk-taking behavior, and mood disruption Conflict with parents and risk-taking do occur, but the idea that adolescents are in a state of distress is exaggerated.

37 Adulthood and Old Age Aging and Intellectual Functions
Infancy and Childhood 4/15/2017 Adulthood and Old Age Aging and Intellectual Functions Memory and Forgetting Cognitive abilities do not inevitably decline. Some elderly may show declines on free-recall tasks, however declines on tests of recognition memory are less likely. Memory declines may be due to impairments in sensory acuity and a slowing of neuronal processing. Psychology, 4/e by Saul Kassin ©2004 Prentice Hall ©2001 Prentice Hall

44 Adulthood and Old Age Social and Personal Development Self-Esteem
Infancy and Childhood 4/15/2017 Adulthood and Old Age Social and Personal Development Self-Esteem Self-esteem is highest in childhood. It drops sharply during adolescence. It increases gradually during adulthood, peaks in the sixties, and declines in old age. Figure from: Kassin, S. (2001). Psychology, third edition. Upper Saddle River, NJ: Prentice Hall.

45 Adulthood and Old Age Dying and Death
Infancy and Childhood 4/15/2017 Adulthood and Old Age Dying and Death Elisabeth Kübler-Ross proposed five stages in approaching death: Denial (“It must be a mistake.”) Anger (“It isn’t fair!”) Bargaining (“Let me live longer and I’ll be a better person.”) Depression (“ I’ve lost everything important to me.”) Acceptance (“What has to be, has to be.”) Not everyone follows this sequence through the stages and all people do not experience all stages.
