Chapter 10 Review Flashcards
Conception to 2 weeks
Germinal stage
Zygote becomes a mass of cells that implants in the uterine wall and the placenta begins to form
Germinal stage
2 weeks to 8 weeks
Embryonic stage
Most vital organs and bodily systems begin to form (very vulnerable)
Embryonic stage
8 weeks to birth
Fetal stage
Organs continue to grow and gradually begin to function
Fetal stage
22 to 26 weeks
Age of viability
Inside uterus; protects baby against injury
Amniotic sac
Drinking fluid; keeps temp at constant 100 degrees Fahrenheit
Amniotic fluid
Connected to baby via umbilical chord; provides oxygen and nourishment
Placenta
Prime age span for childbirth
20 to 28
Higher chance for this type of problem in older men’s children
Gene problems
Most important from last 3 months of pregnancy to 2 years
Nutrition
Causes babies to be born with some degree of mental retardation and distorted face and body features
Alcohol (FAS)
Causes lighter weight babies with respiratory problems
Nicotine
Causes babies to often be born addicted
Street drugs
Causes possibility of hemorrhage during birth - dangerous for children and mother
Aspirin
Vision capacities of newborns
Near-sighted - can see less than 8 inches in front of their face
First color seen by newborns
Red
Hearing capacities of newborns
Very well-developed
Effects of high / low pitch sounds
High - keep awake
Low - put to sleep
Taste capacities of newborns
More developed at birth than at any other time in life
Smell capacities of newborns
Very acute - can tell difference between mother’s breast milk and other types
Increases newborns’ risk for birth complications and deficits
Maternal malnutrition
Can interfere with prenatal development
Maternal illness
STD’s that can be passed to newborns
Genital herpes and AIDS
Nature
Heredity
Nurture
Environment
Nature determines potential, nurture determines expression
Interactionist position
Heat to foot trend
Cephalocaudal trend
Center - outwards trend
Proximodistal trend
Follows cephalocaudal and proximodistal trends
Motor development
Attributes to early progress in motor skills
Maturation
Research suggests this is also important to early motor skill progression
Infant’s exploration
Cross-cultural research shows both these traits are influential in developing motor skills
Maturation and environment
1 group of subjects is observed repeatedly over time
Longitudinal research
Group of subjects of varied ages are observed at a single point in time
Cross-sectional research
Refers to close emotional bonds of affection that develop between infants and caregivers
Attachment
Animals that Harlow studied
Monkeys
Research by Harlow shows what is not key to attachment
Reinforcement
Bowlby argued attachment has what two bases
Biological and evolutionary
Infant-mother attachment falls into 4 catagories
Normal
Anxious
Avoidant
Disorganized
Traits of infants with relatively secure attachments
Resilient, competent, high self-esteem
Characteristic mood, activity level, and emotional reactivity
Temperament
Thomas and Chess found in a longitudinal study that temperament remains
Stable
Kagan’s research suggests inhibited and uninhibited temperament are stable over time and have what kind of basis
Genetic
Children progress through thinking through complementary processes of assimilation (borg) and accomodation
Piaget
Birth - 2 years
Sensorimotor (stage 1)
Infants know the world mostly in terms of sensory impressions and motor activities
Sensorimotor (stage 1)
2 - 7 years
Preoperational (stage 2)
Language first develops; children do not comprehend mental operations of concrete logic
Preoperational (stage 2)
Cannot see things from another’s viepoint
Egocentrism
Same amount of something exists regardless of form
Lack of conservation
7 - 11 years
Concrete operational (stage 3)
Children gain mental operations enabling them to think logically about concrete events
Concrete operational (stage 3)
11 - adult years
Formal operational (stage 4)
People thinking logically about abstract concepts
Formal operational (stage 4)
Stages are not invariable - many have underestimated preoperational children - experience may be more important than age
Criticisms of Piaget
Proposes that individuals progress through 3 levels of moral reasoning
Kohlerg’s theory of Moral Development
Acts tend to have consequences
Preconventional reasoning (Kohlberg)
Conform to social order
Conventional reasoning (Kohlberg)
Personal code of ethos
Postconventional reasoning (Kohlberg)
Proposes that individuals evolve through 8 stages over the life span
Erikson’s theory of personality development
Birth - 1 year (Erikson)
Trust vs. Mistrust
2 - 3 years - rules and self control (Erikson)
Autonomy vs. Shame and Doubt
4 - 5 years - responsibility vs. irresponsibility (Erikson)
Initiative vs. Guilt
6 years - puberty - sucess vs. failure - largely due to school (Erikson)
Industry vs. Inferiority
Adolescence - who am I? (Erikson)
Identity vs. Identity confusion
Young adulthood - will only occur if stage 5 is successful (Erikson)
Intimacy vs. Isolation
Done to assist younger generation (Erikson)
Generativity vs. Stagnation
Late adulthood - did I live a good life?
Integrity vs. Despair
2 year span preceding puberty during which secondary sex characteristics begin to devlop
Pubescence
Stage during which primary sex characteristics develop fully
Puberty
Age groups that have an increased risk for psychological and social difficulties
Girls who reach puberty early and boys who mature late
Appears to be last area of brain to fully mature - not complete until late adolescence or early adulthood
Prefrontal cortex
Attempted suicides increase during this age period - but have low success rates
Adolescents
Time of turmoil
Adolescence
Adolescents deal with identity crisis in 4 ways
James Marcia
Remains fairly stable throughout life - some experience signficant changes
Personality
Little research supporting this type of crisis
Mid-life crisis
More likely to be difficult when spouses have different expectations about their roles
Marital adjustment
Transition where children begin to grow up and leave the home
Empty Nest
Represents a major transition and disruption of routine
First child in marriage
Fairly stable through adulthood with slight decrease at age 60
General intelligence
Moderate - associated with aging
Memory loss
Premature commitment - adolescence
Foreclosure
Delay in commitment - adolescence
Moritoreum
Lack of direction - adolescence
Identity diffusion
Sense of self direction - adolescence
Identity achievement
Speed in this area of processing tends to decrease during middle adulthood
Cognitive processing
These areas of sensory domain tend to decrease
Vision and hearing
Women’s reaction to this stage of maturity vary and may not be as stressful as feared
Menopause
Decreases after age 60 but doesn’t appear to related to dementia
Brain tissue and weight
% of people over age 75 with dementia
150-020%
Exhibit profound loss of brain tissue
Alzheimer’s patients
Plaque on the brain and plaque between neurons
Alzheimer’s
