1. During the second trimester, a white, cheeselike substance called __________ emerges on the skin.

• A. lanugo
• B. corpus luteum
• C. vernix
• D. chorion

Correct answer: C

Rationale: During the second trimester of pregnancy, a white, cheeselike substance called vernix emerges on the skin of the developing fetus. Vernix is a protective layer that helps prevent the skin from becoming waterlogged during the time in the amniotic fluid. Choice A, lanugo, is incorrect as lanugo refers to the fine, soft hair that covers the body of a fetus. Choice B, corpus luteum, is incorrect as it is a temporary endocrine structure involved in the menstrual cycle. Choice D, chorion, is incorrect as it is one of the membranes that surround the embryo and later the fetus.

2. In a cross-sectional design, researchers study __________.

• A. the same group of participants repeatedly at different ages
• B. groups of participants differing in age at the same point in time
• C. groups of participants of the same age in different years
• D. participants of the same age at the same point in time

Correct answer: B

Rationale: In a cross-sectional design, researchers study groups of participants differing in age at the same point in time. This design allows researchers to compare different age groups simultaneously, providing valuable insight into age-related differences without the need to track the same group over time. Choice A is incorrect because it describes a longitudinal design where the same group is followed over time. Choice C is incorrect as it involves different groups of the same age studied at different times. Choice D is incorrect as it does not capture the essence of a cross-sectional design, which involves studying groups of different ages at the same point in time.

3. Breastfeeding for just a few weeks ________.

• A. is a rare practice among American women
• B. leads directly to later obesity
• C. is not helpful because, in the beginning, breastfeeding causes constipation
• D. offers some protection against respiratory and intestinal infections

Correct answer: D

Rationale: Breastfeeding for even a short period offers infants protection against respiratory and intestinal infections. Choice A is incorrect because breastfeeding is not a rare practice among American women. Choice B is incorrect as there is no direct link between breastfeeding for a few weeks and later obesity. Choice C is incorrect as breastfeeding does not cause constipation in infants; in fact, it can help prevent constipation.

4. G. Stanley Hall and his student, Arnold Gesell, __________.

• A. discovered that prenatal growth is strikingly similar in many species
• B. launched the normative approach
• C. constructed the first standardized intelligence test
• D. were the forefathers of psychoanalytic theory

Correct answer: B

Rationale: G. Stanley Hall and his student, Arnold Gesell, launched the normative approach. This approach involves studying large numbers of people of different ages and examining the age-related averages of behaviors to establish norms or typical development patterns. These scholars focused on the systematic observation of how and when certain behaviors appear in children. Choices A, C, and D are incorrect because they do not accurately reflect the contributions of G. Stanley Hall and Arnold Gesell in the field of developmental psychology.

5. The mother feels a natural urge to squeeze and push with her abdominal muscles during which stage of labor?

• A. first
• B. second
• C. third
• D. fourth

Correct answer: B

Rationale: The mother feels a natural urge to squeeze and push with her abdominal muscles during the second stage of labor. This stage occurs after the cervix is fully dilated and ends with the delivery of the baby. Choice A (first) is incorrect as the first stage is mainly characterized by the dilation of the cervix. Choice C (third) is incorrect as the third stage is the delivery of the placenta, and choice D (fourth) is incorrect as the fourth stage is the recovery period after childbirth.
