ACTUAL Questions and CORRECT
Answers
What does it mean that cortical organization is lateralized and plastic? - CORRECT ANSWER - -
refers to right and left hemisphere; some functions are lateralized
-ability of brain to change and take on other functions
List and describe the parts of a neuron, including axon, cell body, and dendrite - CORRECT
ANSWER -
How does an impulse travel from one neuron to another? - CORRECT ANSWER - When a nerve
impulse reaches the end of an axon, the axon releases chemicals called neurotransmitters.
Neurotransmitters travel across the synapse between the axon and the dendrite of the next neuron.
Neurotransmitters bind to the membrane of the dendrite.
Mylenization - CORRECT ANSWER - Development of the myelin sheath, a substance that
surrounds nerve fibers; speeds up transmission
sensitive period - CORRECT ANSWER - a point in development when organisms are particularly
susceptible to certain kinds of stimuli in their environments, but the absence of those stimuli does not
always produce irreversible consequences
experience-expectant brain growth - CORRECT ANSWER - the young brain's rapidly developing
organization, which depends on ordinary experiences
ex. development of vision
experience-dependent brain growth - CORRECT ANSWER - growth and refinement of established
brain structures as a result of specific learning experiences that vary widely across individuals and
cultures
ex. what you learn in school
, gross motor skills - CORRECT ANSWER - physical abilities involving large body movements,
such as walking and jumping
fine motor skills - CORRECT ANSWER - physical abilities involving small body movements,
especially of the hands and fingers, such as drawing and picking up a coin
dynamic systems theory - CORRECT ANSWER - the perspective on motor development that
seeks to explain how motor behaviors are assembled for perceiving and acting
locomotion - CORRECT ANSWER - the ability to move from place to place
classical conditioning - CORRECT ANSWER - a type of learning in which one learns to link two
or more stimuli and anticipate events
operant conditioning - CORRECT ANSWER - the learning of voluntary behavior through the
effects of pleasant and unpleasant consequences to responses
novelty preference - CORRECT ANSWER - infants are more likely to pay attention to new objects
or people than those they've seen before.
habituation-dishabituation paradigm - CORRECT ANSWER - a research method used to test
babies' abilities to discriminate between a novel and familiar stimulus
infant vision - CORRECT ANSWER - -20/80 by 6 months, 20/20 by 4 years
-Newborns perceive few colors
Visual Cliff Study - CORRECT ANSWER - to measure infants ability to perceive depth; most
infants older than 6 months will not crawl out over the deep side, indicating that they can perceive depth
