1. How does stress impact brain function?

• A. Stress has no effect on brain function.
• B. Stress can lead to changes in brain structure and function.
• C. Stress can improve brain function.
• D. Stress has no long-term impact on brain function.

Correct answer: B

Rationale: Stress can lead to changes in brain structure and function, affecting mental health and increasing the risk of disorders. Choice A is incorrect as stress does affect brain function. Choice C is incorrect as stress generally has negative impacts on brain function rather than improving it. Choice D is incorrect because stress can have long-term impacts on brain function through structural and functional changes.

2. 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.

3. In a breech presentation, how is the infant positioned for delivery?

• A. Is too large to be delivered vaginally.
• B. Is delivered feet or bottom first.
• C. Is delivered head first.
• D. Appears face down.

Correct answer: B

Rationale: In a breech presentation, the infant is positioned to be delivered feet or bottom first. This is because the baby's pelvis or feet enter the birth canal before the head. Therefore, choice B is correct. Choices A, C, and D are incorrect because a breech presentation specifically refers to the baby being positioned feet or bottom first, not head first, face down, or being too large for vaginal delivery.

4. Marissa wants to study people's emotional reactions to increases in temperature. Her classmate, Bernard, tells her that she should focus on observable behaviors rather than internal states in her study. Bernard's views are most similar to those found in?

• A. The psychodynamic perspective.
• B. The evolutionary perspective.
• C. The behavioral perspective.
• D. The biological perspective.

Correct answer: C

Rationale: Bernard's advice to focus on observable behaviors aligns with the behavioral perspective. Behaviorists emphasize studying external actions rather than internal states to understand human behavior. The psychodynamic perspective (Choice A) focuses on unconscious processes, the evolutionary perspective (Choice B) on adaptation and natural selection, and the biological perspective (Choice D) on the biological underpinnings of behavior, making them less similar to Bernard's suggestion.

5. According to Freud, a person who does not appropriately resolve each psychosexual stage would be _________ at that stage.

• A. defended
• B. fixated
• C. repressed
• D. displaced

Correct answer: B

Rationale: According to Freud's theory of psychosexual development, if a person does not resolve a particular stage successfully, they become fixated at that stage. This fixation can lead to behavior patterns characteristic of that stage in later life. In this context, 'defended' is incorrect because it does not align with Freud's theory of fixation. 'Repressed' is not the correct choice as it refers to the unconscious suppression of thoughts or desires. 'Displaced' involves redirecting emotions from their original source to a substitute target, which is not the concept Freud associated with unresolved psychosexual stages.
