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. ______________ are conditions that increase the probability of a disorder but are neither necessary nor sufficient to cause it.

• A. Risk factors
• B. Contributory causes
• C. Sufficient causes
• D. Protective factors

Correct answer: B

Rationale: The correct term for conditions that increase the probability of a disorder but are neither necessary nor sufficient to cause it is 'Contributory causes.' Risk factors (Choice A) are conditions that increase the likelihood of a negative outcome but do not imply causation. Sufficient causes (Choice C) are conditions that guarantee the occurrence of a disorder by themselves. Protective factors (Choice D) decrease the likelihood of a disorder rather than increasing it.

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. Which part of your brain is active when you get cues about being hungry, thirsty, or sleepy?

• A. Hippocampus
• B. Thalamus
• C. Hypothalamus
• D. Amygdala

Correct answer: C

Rationale: The correct answer is the Hypothalamus (Choice C). The hypothalamus plays a crucial role in regulating basic bodily functions such as hunger, thirst, and sleep. It receives cues related to these needs and helps to maintain homeostasis in the body. The Hippocampus (Choice A) is primarily involved in memory formation and spatial navigation, not in regulating physiological needs. The Thalamus (Choice B) acts as a relay station for sensory information but is not the main center for hunger, thirst, or sleep regulation. The Amygdala (Choice D) is more associated with emotions, particularly fear and pleasure, rather than physiological needs like hunger, thirst, or sleep.

5. While the term psychology has existed since at least the early 1700s, psychology did not come to be considered a science until?

• A. The 1750s.
• B. The early 1800s.
• C. The late 1800s.
• D. The 1940s.

Correct answer: C

Rationale: Psychology became recognized as a science in the late 1800s, aligning with broader trends in scientific inquiry during that period. This marked the establishment of psychology as a distinct field of study based on empirical research and experimentation. Choices A, B, and D are incorrect because psychology's formal recognition as a science occurred later, specifically in the late 1800s.
