1. A baby throws its arms out and then inward (as if embracing) in response to loud noise or when its head falls. Which reflex is this?

• A. Babinski
• B. Palmar
• C. Darwinian
• D. Moro

Correct answer: D

Rationale: The correct answer is D, Moro. The Moro reflex is an instinctual response seen in infants when they experience a sudden loss of support or loud noise. The baby will throw their arms out and then bring them back in, resembling an embrace. This reflex is important for survival as it helps the infant react to potential dangers. Choice A, Babinski, refers to the reflex where a baby's toes spread apart when the sole of the foot is stimulated. Choice B, Palmar, is related to the reflex where a baby's fingers close tightly around an object placed in their palm. Choice C, Darwinian, is not a recognized reflex in this context.

2. How do socioeconomic factors influence mental health?

• A. Socioeconomic factors have no impact on mental health.
• B. Socioeconomic factors are the primary determinants of mental health.
• C. Socioeconomic factors are irrelevant to mental health.
• D. Socioeconomic factors can exacerbate but not cause mental health issues.

Correct answer: B

Rationale: Socioeconomic factors are indeed primary determinants of mental health. These factors influence mental health by impacting access to resources, stress levels, and overall well-being. Choice A is incorrect as socioeconomic factors do have a significant impact on mental health. Choice C is incorrect as socioeconomic factors play a crucial role in mental health outcomes. Choice D is incorrect as socioeconomic factors can both exacerbate and cause mental health issues.

3. In an experiment, the investigators manipulate variables to learn how one affects another.?

• A. A data-collection method in which participants respond to questions
• B. The entire group that is of interest to a researcher
• C. A detailed description of a single culture or context
• D. A study that tests a causal hypothesis

Correct answer: D

Rationale: The correct answer is D because in an experimental design, investigators manipulate variables to determine the effect of one on another. This process allows researchers to test causal hypotheses by manipulating one variable while keeping others constant. Choices A, B, and C are incorrect as they do not directly relate to manipulating variables in an experiment.

4. The baby coos and the mom smiles, so the baby coos again to get mom to smile again. Piaget would say that this action is an example of?

• A. Reflexes
• B. Primary circular reactions
• C. Secondary circular reactions
• D. Tertiary circular reactions

Correct answer: C

Rationale: The correct answer is C: Secondary circular reactions. Secondary circular reactions are repeated actions that infants engage in to trigger a response from the environment, such as the baby cooing to make the mom smile. This behavior is characterized by a focus on the external environment and the repetition of actions to achieve a desired response. Choices A, B, and D are incorrect. Reflexes (choice A) are automatic, involuntary responses to a stimulus, while primary circular reactions (choice B) involve the repetition of actions primarily for the infant's own enjoyment rather than to elicit a response from the environment. Tertiary circular reactions (choice D) refer to the experimentation with new behaviors and variations in the way the infant interacts with the environment.

5. Nearly all adults who were children living in Saigon when the U.S. armed forces left Vietnam in 1975 report that their lives were changed by those events. This exemplifies which of the following?

• A. Normative age-graded influence
• B. Social clock
• C. Critical period
• D. Sensitive period

Correct answer: C

Rationale: The correct answer is C. This scenario exemplifies a critical period in development. Critical periods are specific times in an individual's life when certain events have a profound impact on their development. In this case, the events surrounding the departure of the U.S. armed forces from Saigon in 1975 had a lasting influence on the children living there at that time. Choices A, B, and D are incorrect. Normative age-graded influence refers to events that are common to people of a particular age group, the social clock relates to the culturally preferred timing of social events, and a sensitive period is a time when an individual is more susceptible to environmental influences but does not result in lifelong consequences as with critical periods.
