1. Etiology refers to ________

A. a condition that tends to maintain maladaptive behavior.
B. the causal pattern of a disorder.
C. a predisposition toward developing a disorder.
D. a condition that makes it less likely a person will experience the negative consequences of stress.

Correct answer: B

Rationale: Etiology refers to the causal pattern of a disorder, explaining the factors contributing to the development of a specific condition. Choice A is incorrect as it describes a condition that maintains maladaptive behavior, which is not the definition of etiology. Choice C is incorrect as it refers to a predisposition, which is more related to risk factors rather than the cause itself. Choice D is incorrect as it discusses a condition that reduces the negative consequences of stress, which is not directly related to the cause of a disorder.

2. 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.

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

A. The attachment perspective
B. The interpersonal perspective
C. The humanistic perspective
D. The existential perspective

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.

4. What is extinction, and how might it be used in treating a disorder?

A. Extinction strengthens the conditioned response by continuously pairing the conditioned stimulus with the unconditioned stimulus.
B. Extinction is the process of eliminating a conditioned response by repeatedly presenting the conditioned stimulus without the unconditioned stimulus.
C. Extinction is ineffective and is not used in treating disorders.
D. Extinction is the process of intensifying the conditioned response by pairing the conditioned stimulus with a stronger unconditioned stimulus.

Correct answer: B

Rationale: Extinction is the process of eliminating a conditioned response by repeatedly presenting the conditioned stimulus without the unconditioned stimulus. This process helps in reducing or eliminating undesired behaviors or responses. Choice A is incorrect because extinction weakens the conditioned response by breaking the association between the conditioned stimulus and the unconditioned stimulus. Choice C is incorrect as extinction is a widely used technique in behavioral therapies for treating disorders. Choice D is incorrect as extinction aims to reduce the conditioned response, not intensify it.

5. Sandy took part in the April 2013 Boston Marathon, where two bombs were detonated near the finish line, killing three spectators. For approximately 2 weeks after the marathon, Sandy was unable to sleep or concentrate and often found herself reliving the moment she heard the bombs explode. What disorder might Sandy be diagnosed with?

A. Posttraumatic stress disorder
B. Phobic disorder
C. Panic disorder
D. Acute stress disorder

Correct answer: A

Rationale: Sandy might be diagnosed with posttraumatic stress disorder (PTSD). PTSD typically develops after exposure to a traumatic event and is characterized by symptoms such as re-experiencing the event, avoidance of reminders of the event, negative changes in thoughts and mood, and heightened reactivity. While acute stress disorder can occur shortly after a traumatic event, the duration of symptoms in the scenario suggests a more prolonged impact, aligning with PTSD. Phobic disorder and panic disorder are not as closely related to the described symptoms as PTSD.
