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. A psychologist who is interested in the psychological effect of aging would most likely specialize in?

• A. Developmental psychology.
• B. Experimental psychology.
• C. Cognitive psychology.
• D. Psychometrics.

Correct answer: A

Rationale: A psychologist interested in the psychological effect of aging would most likely specialize in developmental psychology. Developmental psychology focuses on studying the psychological changes that occur throughout a person's lifespan, including the effects of aging. Experimental psychology primarily deals with conducting experiments to study behavior and cognitive processes. Cognitive psychology focuses on mental processes like perception, memory, and problem-solving. Psychometrics involves the measurement of psychological variables such as intelligence, aptitude, and personality traits, but it does not specifically address the psychological effects of aging as in developmental psychology.

3. Biological discoveries ________.

• A. have lessened the subjectivity of definitions of abnormality.
• B. demonstrate that the environment plays only a minimal role in the development of psychopathology.
• C. make it clear that mental disorders are diseases and should be dealt with by the medical profession.
• D. have led to a recognition of the role that genetic factors and other biological influences play in the development of many disorders.

Correct answer: D

Rationale: Biological discoveries have indeed led to a recognition of the role that genetic factors and other biological influences play in the development of many disorders. This understanding has shifted the focus from purely environmental explanations to acknowledging the significant impact of genetics and biology on mental health. Choices A, B, and C are incorrect because biological discoveries have not specifically addressed the subjectivity of definitions of abnormality, minimized the role of the environment in psychopathology, or definitively classified mental disorders as diseases that should only be handled by the medical profession.

4. Which of the following statements about brain dysfunction and psychiatric disorders is correct?

• A. Identifiable brain damage is often the cause of psychiatric disorders.
• B. Brain damage may decrease the risk of developing a psychiatric condition.
• C. Changes in brain function appear to play a role in many psychiatric disorders.
• D. Brain development can be altered by experience, always leading to changes in the brain that decrease the risk of developing a psychiatric condition.

Correct answer: C

Rationale: The correct statement is C: 'Changes in brain function appear to play a role in many psychiatric disorders.' This statement is accurate as research suggests that alterations in brain function are associated with various psychiatric disorders. Option A is incorrect because while brain damage can contribute to some psychiatric conditions, it is not always the primary cause. Option B is incorrect as brain damage typically increases the risk of developing psychiatric disorders. Option D is incorrect because while brain development can be influenced by experiences, it does not always decrease the risk of psychiatric conditions.

5. Which school of psychology takes the most positive view of human nature?

• A. Behaviorism.
• B. Functionalism.
• C. Humanism.
• D. Psychoanalysis.

Correct answer: C

Rationale: The correct answer is C: Humanism. Humanism is a school of psychology that focuses on the positive aspects of human nature, emphasizing personal growth, self-actualization, and the inherent goodness in individuals. Behaviorism (choice A) primarily focuses on observable behaviors and conditioning, functionalism (choice B) emphasizes the functions of consciousness and behavior adaptation, and psychoanalysis (choice D) delves into unconscious thoughts and childhood experiences, rather than having a fundamentally positive view of human nature.
