Post-Natal Period of Development and Theories of Development

Post-Natal Period of Development and Theories of Development Basic Processes of Development Maturation Biological process of systematic physical growth Experience plays a role in specific contexts Children change dramatically from birth to adulthood

Stage Theories of Development Stages series of abrupt changes from one period to another All children must pass through in same order More qualitative than quantitative (such as child mastering physical properties of object) Stages of the Lifespan

Infancy (birth 2 weeks) Babyhood (2 weeks 2 years) Early Childhood (2 -7 years) Late Childhood (7-12 years) Puberty (10-16 years) Adolescence (12-21 years) Young Adulthood (21-35 years) Middle Adulthood (35 50 years) Late Adulthood / Old Age (50 above) 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 Born with a number of reflex behaviors Infant Reflexes Rootingturning the head and opening the mouth in the direction of a touch on the cheek Suckingsucking rhythmically in

response to oral stimulation Graspingcurling the fingers around an object Social and Personality Development Temperament--inborn predisposition to consistently behave and react in a certain way Attachment-- emotional bond between infant and caregiver Quality of Attachment Parents who are consistently warm, responsive, and sensitive to

the infants needs usually have infants who are securely attached Parents who are neglectful, inconsistent, or insensitive to infants needs usually have infants who are insecurely attached Language Development Noam Chomsky asserts that every child is born with a biological predisposition to learn language universal grammar Motherese or infant directed speech--style of speech used by adults (mostly parents) in all

cultures to talk to babies and children Language Development Infant preference for human speech over other sounds before 6 months can hear differences used in all languages after 6 months begin to hear only differences used in native language Cooingvowel sounds produced 24 months Babblingconsonant/vowel sounds between 4 to 6 months Even deaf infants coo and babble

Two-word stage Sentences Early Childhood Growth is less explosive and rapid than during infancy Lasts 2 to 7 years of age Cognitive development *Symbolic thinking, language used *egocentric thinking *imagination / experience grow Early Childhood Emotional and social development Most notable changes in peer

relationships and types of play Solitary play Parallel play Cooperative play Cooperative play Parallel play Solitary play Young Childrens Vocabulary Comprehension vocabulary-words that the infant or child understands Production vocabulary--words

that the infant or child understands and can speak Gender Role Development Gendercultural, social, and psychological meanings associated with masculinity or femininity Gender rolesvarious traits designated either masculine or feminine in a given culture Gender identityA persons psychological sense of being male or female Between ages 2-3 years, children can identify themselves and other children as boys or girls. The concept of gender or sex,

is, however, based more on outward characteristics such as clothing. Gender Differences Toddler girls tend to play more with dolls and ask for help more than boys Toddler boys tend to play more with trucks and wagons, and to play more actively After age 3 years we see consistent gender differences in preferred toys and activities Children are more rigid in sex-role stereotypes than adults Social Learning Theory

Gender roles are acquired through the basic processes of learning, including reinforcement, punishment, and modeling Gender Schema Theory Gender-role development is influenced by the formation of schemas, or mental representations, of masculinity and femininity Children actively develop mental categories of masculinity and femininity and categorize these into gender categories or schemas Trucks are for boys and dolls are for girls is an example of a gender schema Late Childhood Lasts from 7 to 12 years of age

Characterized by slow physical growth Important cognitive changes occur Conservation and reversibility Child decenters allows conservation problems to be solved; learns some matter changes shape but not volume Late Childhood Emotional and social development Child enters with close ties to parents Peer relationships become increasingly important Friendship is more important, last longer Cliques or groups formed, mostly same

sex Terms boyfriend and girlfriend have little meaning at this stage Piagets Theory of Cognitive Development Jean Piaget (18961980) Swiss psychologist who became leading theorist in 1930s Piaget believed that children are active thinkers, constantly trying to construct more advanced understandings of the world Cognitive development is a stage process Piagets Approach

Primary method was to ask children to solve problems and to question them about the reasoning behind their solutions Discovered that children think in radically different ways than adults Proposed that development occurs as a series of stages differing in how the world is understood Piagets Developmental Theory Identified 4 stages of cognitive development Sensorimotor stage infant experiences world in sensory information and motor

activities Preoperational stage children sometimes think illogically by adult standards Concrete operational stage increased abilities Formal operational stage use of full adult logic Sensorimotor Stage (birth 2) Information is gained through the senses and motor actions Child perceives and manipulates but does not reason Symbols become internalized through language development

Object permanence is acquired Object Permanence The understanding that objects exist independent of ones actions or perceptions of them Before 6 months infants act as if objects removed from sight cease to exist Can be surprised by disappearance/reappearance of a face (peek-aboo) Piaget Preoperational Stage (27 years)

Emergence of symbolic thought Egocentrism Lack of the concept of conservation Concrete Operational (712 years)

Increasingly logical thought Classification and categorization Less egocentric Conservation No abstract or hypothetical reason Formal Operational Stage (age 12 adulthood) Hypothetico-deductive reasoning Emerges gradually

Continues to develop into adulthood Summary of Piagets Cognitive Development Theory Birth to 2 Sensorimotor yrs Uses senses and motor skills, items known by use; Object permanence 2 - 7 yrs Symbolic thinking, language used; egocentric thinking, imagination/ experience grow, child de-centers

Pre-operational 7 - 12 yrs Concrete operational 12 yrs onwards Formal operational Logic applied, objective/rational interpretations; conservation, numbers, ideas, classifications Thinks abstractly, hypothetical ideas; ethics, politics, social/moral issues explored

Adolescence Transition stage between late childhood and early adulthood Sexual maturity is attained at this time Puberty--attainment of sexual maturity and ability to reproduce Health, nutrition, genetics play a role in onset and progression of puberty Social Relationships Parent-child relationship is usually positive May have some periods of friction Peers become increasingly important Peer influence may not be as bad as

most people think. Adolescents tend to have friends of similar age, race, social class, and with same religious beliefs. Adolescent Development Physical development Puberty becomes production of sex hormones Primary sex characteristics appear Females menarche: menstruation, ovulation Secondary sex characteristics appear Females breasts, pubic hair, wider hips Males testes and penis growth, facial and pubic hair, broadened shoulders

Adolescence Cognitive development Formal operations stage entered Ability to use abstract concepts Shift to stage varies among individuals; some never reach this stage, others reach it in early adulthood Piagets classic experiment with weights Piagets Balance Test - task: make the weight times the distance equal on both sides of center 4-yr-old 7-yr-old

Adolescent egocentrism Imaginary audience everyone is watching Personal fable belief that s/he is unique Hypocrisy okay for one to do it but not another Pseudostupidity use of oversimplified logic Social development Time of drifting or breaking away from family Adolescence Emotional development G. Stanley Hall time of storm and stress Most adolescents are happy, welladjusted Areas of problems

Parent-child conflicts Mood changes - self-conscious, awkward, lonely, ignored Risky behavior - aggression, unprotected sex, suicide, use of substances or alcohol Eriksons Life-Span Development Theory Development proceeds in stages Each stage is

characterized by a psychosocial challenge or crisis Stages reflect the motivation of the individual Erik Eriksons Eight Stages of Human Development 8 - Integrity vs. despair 7 - Generativity vs. stagnation 6 - Intimacy vs. isolation

Adult Development Genetics and lifestyle combine to determine course of physical changes Social development involves marriage and transition to parenthood Paths of adult social development are varied and include diversity of lifestyles Adulthood Young adulthood through older adulthood Developmental changes continue throughout adulthood: not a single phase of life Taking on adult responsibilities in work

and social relationships Challenges: love, work, play continue changing Adulthood Physical development Growth and strength in early adulthood, then slow process of decline afterwards Speed and endurance Vision and ability to see in weak lighting Hearing and detection of tones Taste intact until later in life; men tend to lose hearing and taste earlier than women Decline affected by health and lifestyles

Adulthood Cognitive development Continues throughout adulthood; some abilities improve while others decline Fluid intelligence peaks in 20s, declines therafter Crystallized intelligence improves until 30s; then declines slowly afterwards Overall, individual rates vary depending on lifestyle and health Adulthood Emotional and social development Many aspects of personality are fairly

stable over time, and changes are predictable On average, adults become less anxious and emotional, socially outgoing, and creative People become more dependable, agreeable, and accepting of lifes hardships Gender differences lessen over time Adulthood Emotional and social development Much disagreement about when and how changes occur during aging differences between stages of

infant/child development and adult development Not all adults go through every stage Order of stages can vary for individuals Timing of stages not controlled by biological maturation Stages of Adult Life Early adulthood Erikson Intimacy versus isolation (17 to 45 years) Levinson - Early adulthood has three stages Entry into early adulthood (17-28) Age 30 transition (28-33)

Culmination of early adulthood (to age 35) Challenges of career, marriage, and parenthood Middle Adulthood Erikson Generativity versus stagnation (35-60 years) Taking stock of what one has, who s/he is Some are happy, some are disappointed Generativity reaching out, not selfcentered Middle Adulthood Levinson four brief stages

Midlife transition (early 40s) Entry to middle adulthood stage (45 to 50) Age 50 transition Culmination of middle adulthood Climactic Female sexual ability to reproduce declines Not all adult development timed by social clock rather than biological clock

Late Adulthood Old age as a time of poor health, inactivity, and decline is a myth Activity theory of aginglife satisfaction is highest when people maintain level of activity they had in earlier years Later Adulthood Erikson (age 60 and onward) Integrity versus despair Looks back over life as a whole: satisfying existence or merely staying alive Levinson devotes little to later years Life expectancy dramatically

increased as have conceptions of old age many have healthy years after retirement Second careers and activism launched Causes of Aging Biological human body deteriorates Psychological Happy or unhappy aging Social activity and slowed intellectual decline or disengagement and isolation Maintain healthy or unhealthy lifestyle Optimism linked to happier, healthier, longer life Death and Dying

In general, anxiety about dying tends to decrease in late adulthood Kubler-Ross stages of dying Denial Anger Bargain Depression Acceptance Kohlbergs Theory of

Moral Development Assessed moral reasoning by posing hypothetical moral dilemmas and examining the reasoning behind peoples answers Proposed six stages, each taking into account a broader portion of the social world Levels of Moral Reasoning Preconventionalmoral reasoning is based on external rewards and punishments Conventionallaws and rules are upheld simply because they are laws

and rules Postconventionalreasoning based on personal moral standards Summary of Kohlbergs Theory of Moral Development Level I: Preconventional moral reasoning Level II: Stage 1 might makes right Stage 2 look out for number one

Stage 3 good girl, Conventional nice boy moral reasoning Stage 4 law and order Stage 5 social Level III: contract Postconventional moral reasoning Stage 6 universal ethical principles Punishment/obedience

orientation: self-interest Instrumental/relativist orientation: quid pro quo Proper behavior for the social approval Proper behavior of the dutiful citizen, obey laws Mutual benefit to all, obey societys rules Defend right/wrong, not just majority, all life is sacred (reflective) Kohlbergs Theory of Moral Development Theory into Practice Sam starts to get out of his seat to sharpen his

pencil without permission. He stops because he realizes that if he does, others might also do so and this could result in disorder in the classroom. Because of this, he understands that it is his duty to follow the rules. Q: At which of Kohlbergs stages of moral development is Sam functioning?
