An inborn trait that is relatively permanent and differentiates one person from another is known as ________.
- A. genotype
- B. phenotype
- C. temperament
- D. characteristic
Correct Answer: C
Rationale: Temperament is the correct answer because it refers to an individual's inborn, relatively permanent trait that distinguishes one person from another. Genotype (choice A) refers to the genetic makeup of an organism, not necessarily a behavioral trait. Phenotype (choice B) is the observable characteristics of an organism resulting from the interaction between its genotype and the environment. Characteristic (choice D) is a broad term that can encompass various traits and features, but it does not specifically denote an inborn and relatively permanent trait that sets individuals apart.

What role do genetic predispositions play in the development of mental disorders?
- A. Genetic predispositions solely determine the development of mental disorders.
- B. Genetic predispositions play a role but are not solely responsible for the development of mental disorders.
- C. Genetic predispositions have no influence on mental disorders.
- D. Genetic predispositions guarantee the development of mental disorders.
Correct Answer: B
Rationale: Genetic predispositions are indeed a factor in the development of mental disorders, but they are not the sole determining factor. While genetics can predispose individuals to certain conditions, environmental factors, lifestyle choices, and life experiences also play a significant role. Choice A is incorrect because mental disorders are influenced by a combination of genetic and environmental factors. Choice C is incorrect as genetic predispositions do have an impact on mental health. Choice D is incorrect as genetic predispositions do not guarantee the development of mental disorders, as other factors also contribute to their onset.
What are some common methods used to study genetic influences on behavior?
- A. Genetic influences are studied only through twin studies.
- B. Common methods include twin studies, adoption studies, and gene mapping.
- C. Genetic influences on behavior are only studied through family history.
- D. Genetic influences on behavior are not well understood.
Correct Answer: B
Rationale: Common methods used to study genetic influences on behavior include twin studies, adoption studies, and gene mapping. Twin studies help to compare the similarities between identical and fraternal twins to estimate the heritability of a trait. Adoption studies look at the similarities between adopted children and their biological and adoptive parents to determine genetic influences. Gene mapping involves identifying specific genes associated with certain behaviors. Choices A, C, and D are incorrect because genetic influences on behavior are not solely studied through twin studies or family history, and while the understanding of genetic influences may vary, there are established methods to study them.
From the cognitive-behavioral perspective, an important limitation with the behavioral perspective is that ________.
- A. Behaviorists went too far in attacking the psychoanalytic perspective.
- B. Behaviorists failed to attend to the importance of mental processes.
- C. Behaviorists were too focused on explaining how abnormal behavior is acquired.
- D. Behaviorists underestimated the role of reinforcement.
Correct Answer: B
Rationale: The correct answer is B because behaviorists, from the cognitive-behavioral perspective, are criticized for not considering the significance of mental processes. This limitation is a key point in the cognitive-behavioral perspective, which emphasizes the interplay between thoughts, feelings, and behaviors. Choices A, C, and D are incorrect because they do not directly address the specific limitation of failing to account for mental processes in the behavioral perspective.
If having a gene for Parkinson's disease guarantees that Parkinson's disease will develop, the gene is a ________.
- A. risk factor
- B. necessary cause
- C. sufficient cause
- D. contributory cause
Correct Answer: B
Rationale: The correct answer is B: necessary cause. A necessary cause is an essential factor for the disorder to occur. In this scenario, if having a gene for Parkinson's disease guarantees the development of the disease, then the gene is a necessary cause. Choice A, 'risk factor,' implies an increased likelihood of developing the disease but does not indicate certainty. Choice C, 'sufficient cause,' indicates that the gene alone can bring about the disease, which is not necessarily true in this context. Choice D, 'contributory cause,' suggests that the gene plays a part in causing the disease but is not essential for its development.
The genetic influences that determine behavior may never be fully understood due to ________
- A. the ease of researching to differentiate between the effects of the environment and the effects of genes.
- B. the likelihood that most behaviors are determined by the interaction of many genes and the environment.
- C. the tendency to rely 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 a complex interaction of many genes and the environment. Choice A is incorrect because it states that it is easy to differentiate between the effects of the environment and genes, which is not the case. Choice C is incorrect because although twin studies are commonly used in genetic research, this alone does not hinder the full understanding of genetic influences on behavior. Choice D is incorrect because even though we have some understanding of how genes impact brain chemistry, this does not mean that we fully understand the genetic influences on behavior.
