1. 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.

2. What are protective factors? Give an example of one and explain how it can impact a person's later functioning.

• A. Protective factors are influences that modify a person's response to environmental stressors, making adverse consequences less likely.
• B. An example of a protective factor is having a warm and caring parent, which may lead to resilience.
• C. Protective factors usually lead to resilience, the ability to adapt successfully to stressful circumstances.
• D. Protective factors always prevent the development of psychopathology.

Correct answer: B

Rationale: Protective factors are influences that modify a person's response to environmental stressors, reducing the likelihood of adverse outcomes. An example of a protective factor is having a warm and caring parent, which can foster resilience in individuals. Resilience allows individuals to adapt successfully to stressful situations. Choice A is incorrect as protective factors do not always prevent adverse consequences but reduce their likelihood. Choice C is incorrect as resilience is the outcome of protective factors, not the other way around. Choice D is incorrect as while protective factors can reduce the risk of psychopathology, they do not always prevent its development.

3. What is a set of age norms defining a sequence of life experiences that is considered normal in a given culture and that all individuals in that culture are expected to follow, which may lead to ____?

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

Correct answer: B

Rationale: The correct answer is B: Social clock; ageism. A social clock refers to the normal sequence of life events in a culture, and not meeting these norms can result in ageism. Choice A is incorrect because normative age-graded influence is not directly related to sexism. Choice C is incorrect as critical period refers to specific time frames for development, not a set of age norms. Choice D, sensitive period, does not directly relate to the concept described in the question.

4. Down syndrome is caused by ________

• A. a chemical imbalance.
• B. a gene on the X chromosome.
• C. possessing an extra X chromosome.
• D. possessing an extra chromosome in chromosome 21.

Correct answer: D

Rationale: Down syndrome is caused by possessing an extra chromosome in chromosome 21, not a chemical imbalance (choice A), a gene on the X chromosome (choice B), or possessing an extra X chromosome (choice C). The presence of an extra copy of chromosome 21, also known as trisomy 21, leads to the characteristic features and health problems associated with Down syndrome.

5. 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.
