Exam 4 Psychology
1. How is pruning best defined?
- A. The process of eliminating unused synapses
- B. The process of synapse development
- C. The connection between neurons
- D. Fatty sheath that wraps around neurons and enables them to transmit information more rapidly
Correct answer: A
Rationale: Pruning is the process of eliminating unused synapses in the brain. This process helps the brain to become more efficient by strengthening important connections and eliminating unnecessary ones. Choice B is incorrect because pruning is about eliminating synapses, not developing them. Choice C is incorrect as it refers to the general concept of connections between neurons, not specifically about pruning. Choice D is incorrect as it describes the myelin sheath, which is responsible for rapid transmission of information along neurons, not pruning.
2. Where is the site of chemical communication in the brain?
- A. Neuron
- B. Synapse
- C. Axon
- D. Dendrite
Correct answer: B
Rationale: The correct answer is B: Synapse. The synapse is the site where chemical communication occurs between neurons. Neurotransmitters are released from the axon terminal of one neuron, cross the synaptic cleft, and bind to receptors on the dendrites of the next neuron. Choice A, Neuron, is incorrect as it refers to the entire nerve cell. Choices C and D, Axon and Dendrite, are also incorrect as they are specific parts of a neuron and not the primary site of chemical communication.
3. What did Freud believe about castration anxiety among boys?
- A. Results in penis envy.
- B. Dissolves the Oedipus complex.
- C. Cognitive; learning.
- D. Biological; ecological.
Correct answer: B
Rationale: Freud believed that castration anxiety among boys leads to the resolution of the Oedipus complex, not penis envy or cognitive learning. The Oedipus complex is a central psychodynamic concept in Freudian theory, where boys develop unconscious desires for their mothers and view their fathers as rivals, fearing castration by their fathers as a consequence.
4. What term refers to the mental processes involved in acquiring knowledge?
- A. Cognition.
- B. Pedagogy.
- C. Empiricism.
- D. Introspection.
Correct answer: A
Rationale: The correct answer is A, cognition. Cognition encompasses mental processes like thinking, remembering, and problem-solving, all crucial in acquiring knowledge. Pedagogy (choice B) refers to the method and practice of teaching. Empiricism (choice C) is a theory that states knowledge comes from sensory experience. Introspection (choice D) involves examining one's own conscious thoughts and feelings, not specifically focused on acquiring knowledge.
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.
