chapter 10: lifespan development Flashcards
cross sectional design
measure and compare ppl of different ages at given point in time
longitudinal design
follow development of same set of individuals through time
cohort effects
difference in generations (millenials, gen z)
stages
steps
continuous
slow changes
stability and change
how we change as we age
4 weeks of embryo
mid-brain, hind brain, auditory vesicle, optic vesicle
7 weeks of embryo
metencephalon (cerebellum and pons), spinal cord
11 weeks of embryo
cerebellum, medulla, spinal cord, cerebral hemisphere, optic chiasm
7 months of embryo
cerebrum, cerebellum, spinal cord
9 months of baby
cerebrum, cerebellum, spinal cord
plasticity
change activity of nervous system. nutrition, teratogens, fetal development
teratogens
druugs, toxins that impair process of development
preterm infants
born earlier than 36 weeks
25 weeks= 50% survival
30 weeks= 95% survival
NIDCAP
helps preterm
4 months before birth
gestures, brain signals from eyes to ears
7-8 months before birth
fetus can listen
smell at birth
cringe at bad odours, discriminate mom’s breastmilk
when can newborns know perception
8-12 months
synaptogenesis
form of new synaptic connections
synaptic pruning
loss of weak nerve cell connections (when nerve cells arent being used too much)
the 6 reflexes
rooting reflex: learn feeding and sucking motions
moro reflex: startle when they lose head support
grasping reflex: grasping and holding
stepping reflex: learn to take steps
sucking and swallowing: roof of mouth is stimulated
tonic neck: when head turns
sensitive periods
language fluency, perception, recognize parents, balance, identify culture
