1. __________ supplementation early in pregnancy reduces the risk of abnormalities of the neural tube, the circulatory system, and the urinary tract.

• A. Vitamin A
• B. Folic acid
• C. Vitamin D
• D. Vitamin C

Correct answer: B

Rationale: Folic acid supplementation early in pregnancy is crucial as it reduces the risk of abnormalities in the developing fetus. It is specifically known to prevent issues related to the neural tube, circulatory system, and urinary tract. Vitamin A, Vitamin D, and Vitamin C do not play the same role as folic acid in preventing these specific birth defects, making them incorrect choices.

2. Sigmund Freud constructed his psychosexual theory __________.

• A. on the basis of his adult patients' memories of painful childhood events
• B. by conducting studies of animal behavior
• C. on the basis of interviews with institutionalized children and adolescents
• D. by carefully observing his own children

Correct answer: A

Rationale: Sigmund Freud constructed his psychosexual theory on the basis of his adult patients' memories of painful childhood events. Freud believed that events in early childhood had a significant impact on an individual's development and personality. He used his patients' recollections of childhood experiences to develop his theories on psychosexual development. Choice B is incorrect as Freud did not base his theory on studies of animal behavior. Choice C is incorrect as Freud's theory was not solely based on interviews with institutionalized children and adolescents. Choice D is incorrect as Freud did not construct his theory by observing his own children.

3. Piaget’s cognitive-developmental theory, information processing, and Vygotsky’s sociocultural theory all stress __________.

• A. nature over nurture
• B. changes in thinking
• C. unconscious motives and drives
• D. the effects of punishment and reinforcement on behavior Answer: B Page Ref: 26 Skill Level: Understand development. Topic: Comparing and Evaluating Theories Difficulty Level: Difficult

Correct answer: B

Rationale: Piaget’s cognitive-developmental theory, information processing, and Vygotsky’s sociocultural theory all stress changes in thinking. These theories focus on how cognitive abilities develop over time, emphasizing the growth and transformation of thinking processes rather than static traits or characteristics.

4. The influence of situational factors on moral judgments indicates that like Piaget's cognitive stages, Kohlberg's moral stages are __________.

• A. predictable and universal
• B. highly organized and sequential
• C. attained in a neat, stepwise fashion
• D. loosely organized and overlapping

Correct answer: D

Rationale: The correct answer is D. Kohlberg's moral stages are not strictly sequential but rather overlap and are more fluid, much like Piaget's cognitive stages. Choices A, B, and C are incorrect because Kohlberg's stages do not follow a neat, predictable, or highly organized pattern, as they can be revisited and experienced in varying orders.

5. In field experiments, researchers __________.

• A. selectively assign participants to treatment conditions in natural settings
• B. cannot use random assignment or manipulate treatment conditions
• C. randomly assign participants to treatment conditions in natural settings
• D. have stronger control over the treatment than in the laboratory

Correct answer: C

Rationale: In field experiments, researchers randomly assign participants to treatment conditions in natural settings. This method allows for a higher level of control over potential confounding variables compared to non-random assignment. Random assignment helps ensure that the groups being compared are comparable at the beginning of the study, which strengthens the internal validity of the research findings. Choice A is incorrect because selective assignment may introduce bias. Choice B is incorrect as researchers can use random assignment in field experiments. Choice D is incorrect because field experiments typically have less control over the treatment compared to laboratory experiments.
