1. Dr. O'Connor wants 90-year-old Mr. Takashi to participate in a research study that involves moderate risks. Mr. Takashi is incapable of consenting. Which statement best expresses your advice regarding Mr. Takashi's participation in the study?

• A. He should not be allowed to participate in the study under any circumstances.
• B. He should be allowed to participate in the study regardless of the benefit.
• C. He should be allowed to participate in the study only if his participation will benefit others.
• D. He should be allowed to participate in the study only if it is likely to benefit him directly.

Correct answer: D

Rationale: Mr. Takashi should be allowed to participate in the study only if it is likely to benefit him directly. This decision aligns with the principle of beneficence in research ethics, which emphasizes maximizing benefits and minimizing risks for research participants. Since Mr. Takashi is incapable of giving consent, his participation should be based on the likelihood of direct benefits to him rather than solely for the benefit of others or solely for research purposes. Option A is too restrictive and does not consider potential benefits to Mr. Takashi. Option B is flawed as it disregards the need for the study to benefit Mr. Takashi. Option C focuses on benefiting others, which is not the primary consideration when the participant cannot give consent.

2. Around __________, Baby Alanna should begin to prefer a salty taste to plain water.

• A. 2 weeks
• B. 6 weeks
• C. 2 months
• D. 4 months

Correct answer: D

Rationale: At around 4 months of age, babies begin to develop a preference for salty taste over plain water. This preference is part of their sensory development and exploration of tastes. Introducing a variety of flavors, including salty tastes, at this stage helps broaden the baby's palate and acceptance of different foods later on. Choices A, B, and C are incorrect as babies typically do not develop a preference for salty tastes over plain water at 2 weeks, 6 weeks, or 2 months of age. These earlier stages are more focused on milk feeding and the introduction of solid foods usually begins around 4-6 months of age.

3. One criticism of the information-processing approach is that it __________.

• A. underestimates the individual's contribution to his or her own development
• B. ignores transformation in adulthood, concluding that no major cognitive changes occur after adolescence
• C. underestimates the competencies of infants and preschoolers, focusing on older children and adolescents
• D. is better at analyzing thinking into its components than at putting them back together into a comprehensive theory

Correct answer: B

Rationale: The criticism that the information-processing approach ignores transformation in adulthood, concluding that no major cognitive changes occur after adolescence, suggests a limitation of the theory in not fully acknowledging that cognitive development continues throughout the lifespan. This criticism highlights a potential drawback of the approach in terms of its understanding of cognitive changes beyond adolescence. Choice A is incorrect because the criticism is not about underestimating the individual's contribution. Choice C is also incorrect as the criticism is not related to age-specific competencies. Choice D is incorrect as it focuses on a different aspect of the information-processing approach.

4. To avoid exposure to toxoplasmosis, Kaye should ask other family members to __________.

• A. stop smoking
• B. pick up after the dog
• C. change the litter box
• D. feed the fish

Correct answer: C

Rationale: To avoid exposure to toxoplasmosis, Kaye should ask other family members to change the litter box. Toxoplasmosis is a parasitic infection that can be transmitted through cat feces, so it is important for pregnant women to avoid handling cat litter to reduce the risk of infection. Choices A, B, and D are incorrect because they are not directly related to preventing toxoplasmosis. Smoking cessation is important for overall health but not specifically to prevent toxoplasmosis. Picking up after the dog and feeding the fish are not relevant to preventing toxoplasmosis, as the infection is primarily associated with cat feces.

5. A __________ is a means of building schemes in which an infant who has stumbled onto a new experience caused by his or her own motor activity tries to repeat the event again and again.

• A. sensorimotor reflex
• B. circular reaction
• C. mental representation
• D. goal-directed behavior

Correct answer: B

Rationale: A circular reaction is a process where an infant repeats a specific action to explore and learn about the environment through their own motor activity. This repetition helps the infant to understand the consequences of their actions and build cognitive schemes. Sensorimotor reflex (choice A) refers to automatic responses to stimuli, not a purposeful repetition of actions to learn. Mental representation (choice C) involves internal cognitive structures to represent objects or events in the mind, which is different from the repetitive behavior described in the question. Goal-directed behavior (choice D) is purposeful and intentional, unlike the repetitive nature of circular reactions in infants' learning process.
