rooting reflex
when something touches a baby’s cheek, they turn toward that touch, open their mouth, and vigorously root for a nipple.
startle reflex
when arms and legs spring out, quickly followed by fist clenching and loud crying.
grasping reflex
when a baby holds surprisingly tightly to something.
habituation
Once a stimulus becomes familiar and expected, sensitivity to it decreases. As a result, we do not respond as strongly to it as we did in the beginning.
Ex: When people watch scary movies, at first they react very strongly to the frightening scenes. However, the more they watch scary movies, the less they may respond to startling scenes; they become habituated.
maturatiom
- the orderly sequence of biological growth - decrees many of
our commonalities. - sets the basic course of development; experience (nurture) adjusts it. Genes and scenes interact.
adverse childhood experiences
such as severe deprivation or abuse, can slow development, but genetic growth patterns come “factory installed”-they are inborn.
critical period
an optimal period early in the life of an organism when exposure to certain stimuli or experiences produces normal development.
motor development
Fine motor skills (involving the small muscles of the body) and gross motor skills (involving large muscles and whole-body movement).
