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

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. Dr. Haldol has several patients with schizophrenia who appear to exhibit excessive or distorted characteristics in relation to what one might consider normal functioning. Specific symptoms include varied hallucinations and multiple delusions. According to the DSM-5, these are referred to as?

Correct answer: B

Rationale: The correct answer is B: Positive symptoms. Positive symptoms in schizophrenia are behaviors or experiences that are added to normal functioning, such as hallucinations and delusions. These symptoms are considered 'positive' because they represent an excess or distortion of normal functions. Choices A, C, and D are incorrect. Flat affect refers to a reduction in emotional expression, negative symptoms involve deficits in normal functioning such as reduced emotional expression or motivation, and catatonia is a state of unresponsiveness.

3. Down syndrome is caused by ________

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.

4. Which of the following perspectives focuses on social determinants of behavior?

Correct answer: B

Rationale: The interpersonal perspective focuses on social determinants of behavior, emphasizing the impact of social interactions, relationships, and communication on an individual's behavior. This perspective looks at how people's behavior is influenced by their interactions with others and the social environment. Choices A, C, and D are incorrect because they do not primarily focus on social determinants of behavior. The attachment perspective is concerned with emotional bonds between individuals, the humanistic perspective emphasizes personal growth and self-fulfillment, and the existential perspective focuses on individual freedom and responsibility in creating meaning in life.

5. Normal human cells have ________

Correct answer: A

Rationale: Normal human cells have twenty-two chromosome pairs and one pair of sex chromosomes. This is the correct answer as it accurately describes the typical chromosome count in human cells. Choice B is incorrect because it mentions 'twenty-one trisomy chromosome pairs,' which is not characteristic of normal cells. Choice C is incorrect as it suggests having 'two trisomy chromosome pairs,' which is abnormal. Choice D is incorrect as it states 'twenty-three chromosome pairs,' which is not the standard count in normal human cells.
