DEVELOPMENT REA EXAMINATION TEST
2026 QUESTIONS WITH SOLUTIONS
VERIFIED GRADED A+
◉Which of the following statements about physical growth is true?
I. Physical growth is rapid during infancy, slows during early and
middle childhood, and then is rapid again during adolescence.
II. Physical growth is rapid from infancy to its completion in middle
childhood.
III. Physical growth is rapid during infancy, and then is slow from
early childhood through adolescence.
IV. Physical growth is a steady process from infancy through
childhood.
A. I
B. II
,C. III
D. IV
E. II and IV. Answer: (A)
Statement I is true. Physical growth is not a steady process. There
are growth spurts that occur in infancy and in adolescence.
◉Research on the growth hormone (GH) has shown that
A. children with normal thyroid function will grow to be taller than
their genotype with injections of GH
B. children who do not have GH are likely to be mentally retarded
C. children given early treatments of GH develop normally
D. children given GH treatments later can still catch up to their peers
E. vitamin C can simulate GH production in the body. Answer: (C)
,Research on the growth hormone (GH) has shown that as long as a
child who lacks GH is given injections of the hormone early on, he or
she will grow to their full height potential. If GH is given later, the
child does not catch up.
◉Researchers have studied the impact of late versus early
maturation on adolescents' adjustment. Which of the pairs below
have been shown to have the best adjustment outcomes?
A. Early maturing boys and early maturing girls
B. Early maturing boys and late maturing girls
C. Late maturing boys and early maturing girls
D. Late maturing boys and late maturing girls
E. Adolescent adjustment is in fact NOT related to the timing of
maturation.. Answer: (B)
Early maturing boys and late maturing girls have been shown to
experience better adjustment compared to their counterparts—late
maturing boys and early maturing girls. Early maturing boys may
benefit from having larger physical stature than their late maturing
, peers, and early maturing girls may have difficulty adjusting to
puberty and the concomitant physical changes in their bodies. Other
people may treat early maturing girls as if they were older than their
age. Because of this, they may be faced with higher expectations for
their behavior than they are capable of meeting.
◉One theory of biological aging suggests aging is inevitable and is
caused by
A. carcinogens
B. teratogens
C. wear and tear from normal use
D. arteriosclerosis
E. genetic mutations. Answer: (C)
The wear and tear theory of biological aging suggests that aging of
the body is inevitable because of wear and tear on it from normal
use. This theory suggests that, like a machine, over time the body
will wear out.
