FAD 3220 ACTUAL 2026 CORE EXAM TEST QUESTIONS AND
ANSWERS GRADED A+
✔✔expand on the psychophysiological methods - ✔✔- electroencephalogram (EEG):
uses electrodes to record electrical activity in brain; pictorial representation of brain
activity
- computed tomography (CT) scan: computer-generated x-rays of brain; doesn't show
activity
- functional magnetic resonance image (fMRI) scan: detailed, 3-D computer generated
image of brain activity via magnetic field in brain; most effective and intrusive
✔✔expand on experimental research - ✔✔- independent and dependent variable
- must decide on where and what
- field study: occurs in natural setting
- lab study: conducted in controlled setting
- theoretical research: designed to test some developmental explanation and expand
scientific knowledge
- applied research: meant to provide practical solutions to immediate problems
✔✔compare the research methods that measure developmental change - ✔✔-
longitudinal research: behavior of one or more participants in study is measured by age
- cross-sectional research: people of different ages are compared at same point in time
- sequential research: different age groups are observed at several points in time
✔✔chap 1 - ✔✔DONE
✔✔chap 2 - ✔✔BEGIN
✔✔zygote - ✔✔new cell formed by the process of fertilization
✔✔chromosomes - ✔✔rod-shaped portions of DNA that are organized in 23 pairs
✔✔blastocyst - ✔✔fertilized egg that begins to divide and grow in complexity; growth of
cells; during germinal stage
,✔✔germinal stage - ✔✔first and shortest stage of the prenatal period; takes place
during the first 2 weeks following conception
✔✔Embryonic stage - ✔✔the period from 2 to 8 weeks following fertilization during
which significant growth occurs in the major organs and body systems; developing child
has 3 distinct layers: ectoderm, endoderm, mesoderm
✔✔ectoderm - ✔✔outer layer of embryo; produces sense organs, skin, hair, teeth,
brain, and spinal cord
✔✔endoderm - ✔✔inner layer of embryo; produces digestive system, liver, pancreas,
and respiratory system
✔✔mesoderm - ✔✔middle layer of embryo; produces muscles, bones, blood, and
circulatory system
✔✔fetal stage - ✔✔stage that begins at about 8 weeks after conception and continues
until birth
✔✔body proportions - ✔✔fetus increases in length some 20 times; at 2 months, half the
fetus is it's head; at 5 months, head is 3/8ths total size; at birth, head is 1/4 of the body
at 4 months, fetus weighs 4 ounces
at 7 months, weighs 3 lbs
at birth, weighs about 7 lbs
(figure on pg 62)
✔✔infertility - ✔✔inability to conceive after 12 to 18 months of trying to become
pregnant
✔✔miscarriage - ✔✔spontaneous abortion; occurs when pregnancy ends before the
developing child is able to survive outside the womb; embryo detaches from wall of
uterus and is expelled
✔✔abortion - ✔✔a mother voluntarily chooses to terminate pregnancy
✔✔teratogens - ✔✔environmental factor such as a drug, chemical, virus, etc. that
produces a birth defect
✔✔Example of teratogens - ✔✔native american fetuses are more susceptible to the
effects of alcohol than european american fetuses
ex. fetal alcohol syndrome
ex. old age mothers (40-50) are likely to produce children with down syndrome than
young mothers
, ex. rubella (german measles) can cause problems before 11th week of pregnancy
ex. STI's such as gonorrhea can pass to the child
ex. drug use can cause child to have slower learning patterns and can be addicted to
drug when born
✔✔neonates - ✔✔newborns
✔✔birth - ✔✔occurs when the fetus emerges fully from the mother's body
✔✔Apgar scale - ✔✔a standard measurement system that looks for a variety of
indications of good health in newborns
✔✔episiotomy - ✔✔incision sometimes made to increase the size of the opening of the
vagina to allow the baby to pass
✔✔four principles of growth - ✔✔- cephalocaudal principle
- proximodistal principle
- principle of hierarchical integration
- principle of independence of systems
✔✔cephalocaudal principle - ✔✔the principle that growth follows a pattern that begins
with the head and upper body parts and then proceeds down to the rest of the body
✔✔proximodistal principle - ✔✔the principle that development proceeds from the center
of the body outward
✔✔principle of hierarchical integration - ✔✔states that simple skills typically develop
separately and independently but are later integrated into more complex skills
✔✔principle of the independence of systems - ✔✔suggests that different body systems
grow at different rates
✔✔neurons - ✔✔a nerve cell; the basic building block of the nervous system
✔✔synapses - ✔✔tiny gaps between dentrites and axons of different neurons
✔✔Myelin - ✔✔a fatty substance that helps insulate neurons and speeds the
transmission of nerve impulses
✔✔synaptic pruning - ✔✔the elimination of neurons as the result of non-use or lack of
stimulation
