1. Down syndrome is caused by ________

• A. a chemical imbalance.
• B. a gene on the X chromosome.
• C. possessing an extra X chromosome.
• D. possessing an extra chromosome in chromosome 21.

Correct answer: D

Rationale: Down syndrome is caused by possessing an extra chromosome in chromosome 21, not a chemical imbalance (choice A), a gene on the X chromosome (choice B), or possessing an extra X chromosome (choice C). The presence of an extra copy of chromosome 21, also known as trisomy 21, leads to the characteristic features and health problems associated with Down syndrome.

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. ______________ 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.

4. Mental disorders are almost always _______, meaning they are influenced by multiple genes.

• A. environmental
• B. chemical circuits
• C. polygenic
• D. probabilistic

Correct answer: C

Rationale: The correct answer is C: 'polygenic.' Mental disorders are polygenic, which means they are influenced by multiple genes. This term specifically refers to conditions or traits that are caused by more than one gene. Choice A, 'environmental,' is incorrect as it doesn't directly refer to the genetic influence on mental disorders. Choice B, 'chemical circuits,' is incorrect as it is too specific and not a common term used to describe the genetic basis of mental disorders. Choice D, 'probabilistic,' is incorrect as it relates more to the likelihood or chance of something happening rather than the genetic influence on mental disorders.

5. Dr. Rice believes that it is not possible to fully understand emotions unless we understand the purpose that the conscious experiences associated with emotions play in survival and adaptation. Dr. Rice's views are most consistent with those of?

• A. Edward Titchener.
• B. Ivan Pavlov.
• C. Carl Rogers.
• D. William James.

Correct answer: D

Rationale: Dr. Rice's views align with William James, a functionalist, who emphasized understanding the role emotions play in survival and adaptation. William James and other functionalists believed that emotions have a purpose in helping individuals adapt to their environment. Edward Titchener, known for structuralism, focused on the structure of the mind rather than the purpose of emotions. Ivan Pavlov was a behaviorist known for his work on classical conditioning, which is not directly related to the purpose of emotions. Carl Rogers was a humanistic psychologist who emphasized self-actualization and personal growth, not specifically the purpose of emotions in survival and adaptation.
