PSYCH 260 EXAM SCRIPT UPDATED
COMPLETE QUESTIONS WITH ACCURATE
ANSWERS
●● synaptic pruning
Answer: elimination of extra synapses during development
●● pruning
Answer: the process of eliminating unused synapses to increase the
efficiency of neuronal transmissions
●● brain development sequence
Answer: the brain stem begins developing first, followed by the
cerebellum, the limbic system, and finally the cerebral cortex
●● neuroplasticity
Answer: ability to be modified by experience when your body/brain
undergoes something
●● two types of neuroplasticity
Answer: Experience-expectant brain development
& Experience-dependent brain development
,●● experience-expectant brain development
Answer: prewired processes in the brain
●● experience-dependent brain development
Answer: the continuing process of the creation and organization of
neuron connections that occurs as a result of a person's life experiences
●● reflex
Answer: Fixed motor action that always occurs in response to specific
stimuli in the environment - ex. knee-jerk response
●● why do many infant reflexes disappear within a few months after
birth?
Answer: gradual increase in voluntary control over behavior as cerebral
cortex develops
●● gross motor movements
Answer: movements of the large muscles of the body (ex: moving arms
and legs)
●● gross motor milestones
Answer: 1 month - support head
, 3 months - rolling over
6 months - sitting without support
7 months - crawling, standing with support
12 months - walking
●● fine motor movements
Answer: movements of the smaller muscles (ex: grabbing something and
putting it in their mouth)
●● fine motor milestones
Answer: 2 months - holds object
4 months - brings objects to mouth
5-6 months - bangs objects in midline, grabs object
7 months - pulls sting to obtain objects
8-9 months - beginning of hand preference
11 months - pincer grasp - giving them a cheerio and they can get it
12 months - put objects in containers
●● cephalocaudal pattern of development.
Answer: head to tail development - growth that tends to proceed from
the head downward to the rest of the body (GROSS MOTOR
MOVEMENTS)
