Psychology 101 Final Exam

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. Which of the following is true about subjective distress?

A. All individuals with mental illness experience some degree of distress
B. Distress is the only criterion in diagnosing abnormality
C. Its presence is enough for a clinician to determine if someone has a mental illness
D. Some individuals with a mental disorder may not experience subjective distress

Correct answer: D

Rationale: Subjective distress is not universal among individuals with a mental disorder. Choice A is incorrect as not all individuals with mental illness experience distress. Choice B is incorrect because distress is just one of the criteria used in diagnosing abnormality, not the only one. Choice C is incorrect because the presence of subjective distress alone is not sufficient for a clinician to determine if someone has a mental illness.

3. With which of the following statements would a behaviorist agree?

A. Conscious experiences can be studied in an objective, precise way.
B. In order to understand behavior, one must understand the motives behind the behavior.
C. Behavior can only be explained in terms of phenomenology, that is, an individual's interpretation of experience.
D. Psychology should be the science of behavior that can be observed by others.

Correct answer: D

Rationale: The correct answer is D. Behaviorists argue that psychology should focus on observable behavior that can be studied objectively. Choice A is incorrect because behaviorists do not typically focus on conscious experiences, as they are not directly observable. Choice B is incorrect because behaviorists emphasize that behavior can be understood without delving into internal motives. Choice C is incorrect as behaviorists do not exclusively explain behavior through an individual's interpretation of experience; they focus on observable actions and reactions.

4. How does psychoanalytic theory attempt to explain personality, motivation, and mental disorders?

A. Studying observable behavior.
B. Analyzing conscious experience into its basic elements.
C. Focusing on unconscious determinants of behavior.
D. Studying the function or purpose of consciousness.

Correct answer: C

Rationale: Psychoanalytic theory focuses on the unconscious determinants of behavior to explain personality, motivation, and mental disorders. This approach suggests that hidden forces in the unconscious mind influence our thoughts, feelings, and behaviors, shaping our overall psychological makeup. Choice A is incorrect because psychoanalytic theory delves beyond observable behavior. Choice B is incorrect as psychoanalytic theory goes deeper than analyzing conscious experience alone. Choice D is incorrect as psychoanalytic theory is more concerned with unconscious processes rather than the function or purpose of consciousness.

5. What is the diathesis-stress model of psychopathology?

A. The idea that stress is the primary cause of psychopathology.
B. A model that focuses solely on genetic predispositions.
C. A theory that involves only environmental factors in the development of disorders.
D. A person must have both a vulnerability for a disorder and exposure to stressors to develop the disorder.

Correct answer: D

Rationale: The diathesis-stress model of psychopathology posits that individuals must have a vulnerability or predisposition to a disorder (diathesis) and be exposed to stressful environmental factors for the disorder to manifest. This model emphasizes the interaction between genetic or biological vulnerabilities (diathesis) and environmental stressors. Choice A is incorrect because the model does not suggest that stress is the sole cause of psychopathology. Choice B is incorrect as the model considers both genetic predispositions and environmental stressors. Choice C is incorrect because the diathesis-stress model acknowledges the role of both genetic and environmental factors in the development of disorders.
