U9: Developmental Psychology Flashcards
normative development
the typical sequence of developmental changes for a group of people
cross-sectional method
comparing groups of people of various ages on similar tasks
longitudinal method
following a small group of people over a long portion of their lives, assessing change at set intervals
maturationists
emphasize the role of genetically programmed growth and development on the body
maturation
biological readiness
environmentalists
believe that almost all development is the direct result of learning
continuous development
gradual development
discontinuous development
development in stages
critical period
time in which a skill or ability must develop or it may never develop
collectivist culture
a culture where the needs of society are placed before the needs of the individual
individualist culture
a culture that promotes the personal needs above the needs of society
stages
patterns of behavior that occur in a fixed sequence
physical development
starts at conception, zygote –> germinal stage –> embryonic stage –> fetal stage –> neonate
sucking reflex
newborn reflex, triggered by placing something in the baby’s mouth
palmar reflex
newborn reflex, the automatic grabbing elicited by something being placed in one of the newborn’s hands
babinski reflex
newborn reflex, stroking the bottom of the foot causes the toes to splay out
head-turning reflex
newborn reflex, elicited by touching the baby’s cheek
moro reflex
newborn reflex, splaying out of limbs in response to a loss of support
orienting reflex
newborn reflex, orienting themselves to sudden changes in their surroundings
stereotyped ingestive responses
infants innate likes and dislikes; dislike of lemon but liking sugar
reflexive movement
the first step of motor development; primitive, involuntary movements
rudimentary movement
second step of motor development; first voluntary movements (walking, sitting, rolling, crawling)
fundamental movement
third step of motor development; child learns to manipulate their body (running, throwing, catching)
specialized movement
fourth step of motor development; child combines fundamental movements and applies them to specific tasks (substages: transitional substage and application substage)
third eye frog experiment
critical period test, third eye was added to a frog in early development, and it accommodated the brain’s occipital lobe (ONLY works in early development)
cognitive development
development of learning, memory, reasoning, problem-solving, and related skills
Jean Piaget
stages of cognitive development (sensorimotor, preoperational, concrete operational, formal operational), equilibration, assimilation, schema, accommodation
