CHILD PSYCHOLOGY EXAM 2 2025
QUESTIONS AND ANSWERS
Growth patterns of infants (height and weight): - ANS Newborns lose 5-7% body weight in
first few days, then gain 5-6 oz. per week
-5 months: weight doubles... 15lbs
-1 year: weight tripples... 22 lbs
-2 years: weight quadruples... 26 to 32lbs
Grow 1 inch per month in length during the first year, then slows
-1 yr - 1.5x length; ~30 in.
-2 yrs - ~32-35 in.
principles of growth: - ANS 1. Cephalocaudal principle - "head to tail" growth
2. Proximodistal principle - growth from the center of the body outward
3. Differentiation principle - skills go from global to specific and distinct
4. Principle of the independence of systems - different body systems grow at different rates
Brain Development and neuronal communication - ANS Synaptic development - neuronal
connections form
Synaptic pruning - neurons die off due to lack of stimulation
infant sleep patters - ANS -newborns sleep 16 to 17 hours a day in two hour blocks (no
discernible sleep pattern)
-2 to 4 months sleep pattern emerges

Fine motor skills development - ANS grasp rattler (ulnar), pick up food (pincer), hold cup
Gross motor skills developement - ANS sitting up, crawling, and walking
terms and conditions related to malnutrition - ANS Malnutrition - improper amount and
balance of nutrients
FTT - failure to gain weight within normal limits
Marasmus - wasting away due to lack of nutrients
Kwashiorkor - protein-energy malnutrition
Nonorganic failure to thrive - infant stops growing due to lack of stimulation and attention
Canalization - tendency to return to genetically determined pattern of growth
