1. While out for a walk, you come across a ferocious dog. You feel your heart beating faster and your palms begin to sweat. Which part of the peripheral nervous system is activated in this situation?

• A. Autonomic
• B. Sympathetic
• C. Parasympathetic
• D. Somatic

Correct answer: B

Rationale: The correct answer is B: Sympathetic. When encountering a stressful situation like a ferocious dog, the sympathetic nervous system is activated, leading to the 'fight or flight' response. This response triggers physiological changes like increased heart rate, sweating, and heightened alertness to prepare the body to deal with the perceived threat. The autonomic nervous system (Choice A) encompasses both the sympathetic and parasympathetic divisions, so it's a broader category. The parasympathetic nervous system (Choice C) is responsible for the body's 'rest and digest' functions, which are opposite to the physiological changes seen in a stress response. The somatic nervous system (Choice D) controls voluntary movements and sensory information, not the physiological responses seen in a stress reaction.

2. Why is it particularly useful to study identical twins who were raised in different environments?

• A. Differences in brain function can be easily identified.
• B. Concordance rates tend to be higher.
• C. It is possible that the genetics of twins who have been separated have changed in ways to explain any differences found.
• D. It is possible that high concordance rates between identical twins reared together are due to their being treated more similarly than nonidentical twins.

Correct answer: D

Rationale: Studying identical twins raised in different environments allows researchers to understand the impact of genetics versus environmental factors on traits. Choice A is incorrect because differences in brain function can be influenced by a variety of factors and not solely by environmental differences. Choice B is incorrect as concordance rates tend to be higher in identical twins reared together due to shared genetics and environment. Choice C is incorrect because genetics do not change due to being raised in different environments.

3. Unlike other types of anxiety disorders, this one is not triggered by anything specific, hence the name free-floating anxiety.

• A. Social anxiety disorder
• B. Generalized anxiety disorder
• C. Panic disorder
• D. Specific phobia

Correct answer: B

Rationale: The correct answer is B, Generalized anxiety disorder. Generalized anxiety disorder is characterized by persistent and excessive worry or anxiety that is not triggered by specific situations or objects, hence the term 'free-floating anxiety.' Social anxiety disorder (A) is characterized by fear and anxiety about social situations, panic disorder (C) involves recurrent unexpected panic attacks, and specific phobia (D) is an intense fear of a specific object or situation. Therefore, B is the most appropriate choice in the context of anxiety not being triggered by specific stimuli.

4. Barney helps his younger brother, who has just learned to cycle on his own, to navigate narrow roads and sharp turns. Vygotsky will refer to this as ________?

• A. Microsystem
• B. Macrosystem
• C. Mesosystem
• D. Exosystem

Correct answer: C

Rationale: In this scenario, where Barney is assisting his younger brother in navigating narrow roads and sharp turns, Vygotsky would refer to this as an example of the 'mesosystem.' The mesosystem involves the interactions between different systems in a child's environment, such as family and peers. Choices A, B, and D are incorrect: A) Microsystem refers to the immediate environment where the child lives, like home and school; B) Macrosystem encompasses the larger cultural context; D) Exosystem involves external settings that indirectly influence the child.

5. You are taking part in a survey that asks about your attitudes toward physical punishment of children. Even though you believe that spanking is sometimes necessary, you answer that you are opposed to any sort of physical punishment. Which of the following terms best describes why you answered the way you did?

• A. Random responding
• B. Faking bad
• C. Placebo effect
• D. Social desirability

Correct answer: D

Rationale: The correct answer is D, social desirability. Social desirability bias occurs when respondents answer questions in a way they think will be viewed favorably by others, rather than according to their true beliefs. In this scenario, the respondent may feel pressured to provide an answer that aligns with societal norms or expectations, even if it contradicts their personal beliefs. Choices A, B, and C are incorrect. Random responding refers to answering survey questions haphazardly, without consideration. Faking bad is intentionally providing extreme or negative responses. The placebo effect is a phenomenon where a person's belief in a treatment's effectiveness produces a positive outcome, unrelated to the treatment's actual effects.
