Studies the role played by our genes and our environment in mental ability, emotional stability, temperament, personality, interests, etc.; they look at the causes of our individual differences
Giving priority to the goals of one's group (often one's extended family or work group) and defining one's identity according to those goals
Giving priority to one's own goals over group goals and defining one's identity in terms of personal attributes rather than group identification
Fraternal twins; siblings share about half of the same genes because the develop from 2 different zygotes
Identical Twins; individuals who share all of the same genes/heredity because they develop from the same zygote
studies how natural selection favored behaviors that contributed to survival and spread of our ancestors' genes; evolutionary psychologists look at universal behaviors by all people
Child's understanding that his/her sex won't change even if s/he acts like the opposite sex
gender role stereotypes
Broad categories that reflect our impressions and beliefs about males and females
Gender Schema Theory
Mental set of what society considers appropriate behavior for each of the sexes - idea that children learn from their cultures what it means to be male and female and that they adjust their behavior accordingly
The amount of variation/difference among a group of individuals that is due to genetic causes, not environmental causes - IS NOT THE SAME THING AS INHERITED!
Usually have 3 copies of chromosome-21 in their cells, are typically cognitively impaired and poor muscle tone and coordination
Dominant gene defect that involves degeneration of the nervous system, characterized by tremors, jerky motions, blindness, and death
Recessive trait that produces progressive loss of nervous function and death in a baby
Females with only one X sex chromosome; causes some physical characteristic like shortness, webbed necks, and differences in physical sexual development
Fetal Alcohol Syndrome (FAS)
results in slow mental and physical growth in children whose mothers consumed large amounts of alcohol during pregnancy - low IQ, a small head w/ a flat face, misshapen eyes, a flat nose, & thin upper lip
An infant's natural disposition to show a particular mood at a particular intensity for a specific period
constantly seeing the world from your own viewpoint - believing that it's "all about you" (preoperational stage)
the concepts that babies believe objects continue to exist even when they are out of sight
changes in the form of an object do not alter physical properties of mass, volume, and number
observing the behavior of others in social situations to obtain information or guidance (skills develops between ages 1 & 2)
after absence of mom, baby is angry and rejects, avoids, ignores her, or behaves inconsistently
democratic style - set limits, but explain the reasons for rules with their children, and make exceptions when appropriate
tend not to set firm guidelines, if they set any at all - some let children do whatever they want, & others tend to ignore their children
conducted over a long period of time using the same subjects - allows researchers to study the effects of early experiences on later life development
cross-sectional groups who are assessed at least 2 or 3 times over a span of months or years, rather than just once. Results from one cohort are compared with other cohorts at the same age to evaluate their similarity
differences among a cohort found during a cohort sequential study - are used to identify age related changes
Continuity versus Discontinuity
another major controversy in psychology - deals with the question of whether development is a gradual, cumulative change from conception to death (continuity), or a sequence of distinct stages (discontinuity)
Stability versus Change
another big controversy in psychology - deals with the issue of whether or not personality traits present during infancy endure throughout the lifespan
a time interval during which specific stimuli have a major effect on development (stimuli do not have this dramatic effect during other times - only at this specific time)
learned knowledge & skills such as vocabulary (generally improves with age)
those abilities requiring speed or rapid learning (generally diminishes with aging)
offers the possibility of correcting genetic defects by introducing healthy cells into existing cells
(startle reflex) - loud noise or sudden drop causes neonate to automatically arch his/her back, fling his/her limbs out, and quickly retracts them
neonate's (newborn's) response of turning his or her head when touched on the cheek and then trying to put the stimulus into his or her mouth
decreasing responsiveness with repeated presentation of the same stimulus (not responding to something after you have experienced it over and over and over) classic example: the little boy who cried wolf
an example of an instinct that involves some learning - ex: many birds, such as ducklings, will follow moving objects soon after hatching...usually this is the mother. If the mother is not present the ducklings will follow other moving objects, such as a researcher
alternative idea regarding cognitive development - emphasizes continual change in the efficiency of processing information rather than a fixed sequence of stages of development
biological growth processes that bring about orderly changes in behavior, thought, or physical growth - is relatively unaffected by experience
