FRHD 1010 CHAPTER 3 DEFINITIONS | HUMAN DEVELOPMENT STUDY GUIDE | PRACTICE
QUESTIONS AND ANSWERS
Deferred imitation - correct answer ✔✔sequence in which an infant first perceives something
done by someone else and then performs the same action hours or even days later
Neuron - correct answer ✔✔nerve cells in the central system, especially brain
Cortex - correct answer ✔✔outer layers of brain in humans and other mammals
Synapses - correct answer ✔✔tiny gaps are critical communication links within the brain
Axon - correct answer ✔✔fiber that extends from a neuron and transmits electrochemical
impulse from that neuron to the dendrites of other neurons
Dendrite - correct answer ✔✔fiber that extends from a neuron and receives electrochemical
impulses transmitted from other neurons via their axons
Head-sparing - correct answer ✔✔phenomenon by which the brain continue to grow even
though the body stops growing in a malnourished child
REM sleep (Rapid Eye Movement sleep) - correct answer ✔✔stage of sleep characterized by
flickering eyes behind closed lids, dreaming, and rapid brain waves
Sensation - correct answer ✔✔process by which the visual, auditory and other sensory systems
detect stimuli
Perception - correct answer ✔✔occurs when the brain tries to make sense out of a stimulus so
that the individual becomes aware of it
, Binocular vision - correct answer ✔✔ability to focus the two eyes in a coordinated manner in
order to see one image
Gross Motor - correct answer ✔✔physical abilities involving large body movements
Fine Motor - correct answer ✔✔physical abilities involving small body movements
Pincer movement - correct answer ✔✔use the thumb and forefinger to pick up objects
Stunting - correct answer ✔✔failure of children to grow to normal height for their age due to
severe and chronic malnutrition
Wasting - correct answer ✔✔tendency for children to be severely underweight for their age as a
result of malnutrition
Sensorimotor intelligence - correct answer ✔✔Piaget's term for the way infants think - by using
their senses and motor skills
Circular reaction - correct answer ✔✔sense, perceive, think
Primary circular reactions - correct answer ✔✔infant senses motion, sucking, noise and other
stimuli and tries to understand them
Secondary circular reactions - correct answer ✔✔infants respond to other people, to toys and
any other object they can touch or move
