1. The process of ________ is used to increase the probability that a behavior will occur.

• A. operant conditioning
• B. reinforcement
• C. classical conditioning
• D. punishment

Correct answer: B

Rationale: The correct answer is reinforcement. Reinforcement involves providing a consequence that increases the likelihood of a behavior being repeated. Operant conditioning (Choice A) refers to learning through consequences for behavior, which includes reinforcement and punishment. Classical conditioning (Choice C) involves forming associations between stimuli and involuntary responses. Punishment (Choice D) involves providing a consequence that decreases the likelihood of a behavior being repeated. In this context, the question specifically asks about a process that increases the probability of a behavior occurring, aligning with the concept of reinforcement.

2. What research method involves researchers using interviews and/or questionnaires to collect data about attitudes, interests, values, and various kinds of behaviors?

• A. Case study
• B. Survey
• C. Naturalistic observation
• D. Correlational study

Correct answer: B

Rationale: The correct answer is B: Survey. A survey is a research method where data is collected through interviews or questionnaires about various behaviors and attitudes. In a case study (choice A), researchers closely examine a particular individual or group. Naturalistic observation (choice C) involves observing subjects in their natural environment. Correlational study (choice D) examines the relationship between two variables but does not involve collecting data through interviews or questionnaires.

3. 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.

4. What major departure did Freud's position have from prevailing viewpoints around the early 1900s?

• A. Viewed abnormal behavior as resulting from biological causes.
• B. Viewed people as not fully aware of the forces that control their behavior.
• C. Proposed the existence of free will.
• D. Emphasized environmental forces on behavior.

Correct answer: B

Rationale: Freud's major departure from prevailing viewpoints around the early 1900s was that he viewed people as not fully aware of the forces that control their behavior. This is reflected in his emphasis on unconscious forces influencing behavior. Choice A is incorrect as Freud focused on psychological rather than solely biological causes. Choice C is incorrect as Freud's theory did not emphasize free will but rather unconscious drives. Choice D is incorrect as Freud emphasized internal psychological forces over external environmental factors.

5. Normal human cells have ________.

• A. twenty-two chromosome pairs and one pair of sex chromosomes.
• B. twenty-one trisomy chromosome pairs, one autosomal pair, and one pair of sex chromosomes.
• C. twenty-one chromosome pairs and two trisomy chromosome pairs.
• D. twenty-three chromosome pairs.

Correct answer: A

Rationale: The correct answer is A. Normal human cells have twenty-two chromosome pairs and one pair of sex chromosomes. This adds up to a total of 46 chromosomes. Choice B is incorrect as it mentions twenty-one trisomy chromosome pairs, which is not a characteristic of normal human cells. Choice C is also incorrect as it states twenty-one chromosome pairs and two trisomy chromosome pairs, which is not accurate for normal human cells. Choice D is incorrect as it mentions twenty-three chromosome pairs, which is not the correct number for normal human cells.
