Chapter 11 Flashcards
developmental psychology
studying a lifespan and the change and continuity across the lifespan
germinal stage
2 week period that begins at conception, brief lifetime of zygote
zygote
fertilized egg that contains chromosomes from both sper and egg
embryonic stage
period that lasts from week 2-8, looks like a nut or bean
fetal stage
period that lasts from week 9 to borth
characterized by rapid brain growth, body development and myelination
myelination
formatiob of a fatty sheath around axons begins
when can fertilization happen
1-5 days after conception
why arent humans fully neurally developed at birth
wouldnt be able to come out
humans need to adapt to a wide range of environments throughout their life and the brain must develop to meet these challenges
placenta
organ that links mother to baby, permitting material exchange
food and substances taken by the mother affects development
teratogens-definition
agents such as drugs or viruses that pass from mother and impair the development process
teratogens-examples
alcohol
tobacco
caffeine
stress
intrauterine growth restriction
limits baby from growing properly
how long does infancy last
birth to 18-24 months
when does stranger anxiety develop
after you learn how to move, development of survival instinct
what do newborns respond to the most
faces and facial features, can mimick facial features within first hour of life, can care about and respond to them
can babies learn the difference between possible and impossible events
yes
what is motor development
emergence of the ability to execute physical action such as reaching, grasping, crawling, walking
motor reflexes
specific patterns of motor response that are triggered by specific patterns of sensory stimulation (rooting and sucking)
cephalocaudal rule
develop top to bottom
proximodistal rule
develop inside to outside
approx. how many steps and falls does a 12-19 month old take in an hour
2 368 steps and 17 falls
scale errors
infants arent aware of how most physics work
ex: trying to fit into small things
cognitive development
emergence of the ability to think and understand
who suggested the 4 stages of cognitive development
