1. How do early life experiences shape brain development and behavior?
- A. Early life experiences have no impact on brain development.
- B. Early life experiences are crucial in shaping brain development and later behavior.
- C. Early life experiences are not significant in brain development.
- D. Early life experiences are easily overcome by adulthood.
Correct answer: B
Rationale: Early life experiences are crucial in shaping brain development and later behavior. These experiences play a significant role in laying the foundation for future mental health and behavior. Choice A is incorrect because early life experiences do have a profound impact on brain development. Choice C is incorrect as early life experiences are indeed significant in brain development. Choice D is incorrect as early life experiences can have lasting effects into adulthood.
2. Freud's psychosexual stage that occurs between the ages of 3 and 5 and includes the Oedipal period is the ________ stage.
- A. genital
- B. oral
- C. phallic
- D. latency
Correct answer: C
Rationale: Freud's psychosexual stage that occurs between the ages of 3 and 5, including the Oedipal period, is the phallic stage. During this stage, children experience the Oedipus or Electra complex, where they develop unconscious sexual desires for the opposite-sex parent and see the same-sex parent as a rival. The genital stage (Choice A) is the final stage where mature sexual interests emerge, oral (Choice B) and anal stages precede the phallic stage, and latency (Choice D) is a stage following the phallic stage characterized by a focus on developing social and cognitive skills.
3. The understanding of genetic influences on behavior may never be fully achieved due to ________.
- A. the ease of researching to differentiate between the effects of the environment and genes.
- B. the likelihood that most behaviors are determined by the interaction of many genes and the environment.
- C. the reliance on twin studies in genetic research.
- D. our significant understanding of how genes impact brain chemistry.
Correct answer: B
Rationale: The correct answer is B because most behaviors are influenced by the interaction of multiple genes and the environment. Choice A is incorrect because it suggests that researching the effects of the environment and genes is easy, which is not the case. Choice C is incorrect as it focuses on a specific method (twin studies) rather than the broader concept of gene-environment interaction. Choice D is incorrect as the statement implies a high level of understanding that contradicts the idea that genetic influences on behavior may never be fully understood.
4. After cheating on her husband and feeling ashamed, Julia accused her husband of cheating. Such behavior is explained by which of the following defense mechanisms?
- A. Sublimation
- B. Displacement
- C. Projection
- D. Rationalization
Correct answer: C
Rationale: The correct answer is C, Projection. Projection is the defense mechanism where one attributes their own unacceptable feelings to others. In this scenario, Julia is projecting her feelings of guilt and shame onto her husband by accusing him of cheating. Sublimation (choice A) involves channeling unacceptable impulses into socially acceptable activities. Displacement (choice B) is redirecting emotions from the original source to a substitute target. Rationalization (choice D) is providing logical explanations to justify unacceptable behavior, which is not applicable in this context.
5. ______________ 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.
