1. In order for one to be diagnosed with panic disorder, the panic attacks must?

A. Suddenly; unexpectedly
B. Suddenly; gradually
C. Gradually; unexpectedly
D. Unexpectedly; suddenly

Correct answer: A

Rationale: The correct answer is A: 'Suddenly; unexpectedly.' Panic disorder is diagnosed when panic attacks occur unexpectedly, not gradually. Panic attacks are characterized by their sudden onset and are unpredictable. Choice B is incorrect because panic attacks do not manifest gradually. Choice C is incorrect because panic attacks are not expected or predicted. Choice D is incorrect as well because the unexpected nature of panic attacks is a key criterion for diagnosing panic disorder.

2. 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.

3. Strict behaviorists would be most sympathetic to which one of the following statements?

A. Human behavior is primarily caused by inherited factors.
B. Human behavior is primarily caused by environmental factors.
C. Human behavior is primarily caused by equal contributions of inherited and environmental factors.
D. No one really knows the primary causes for human behavior.

Correct answer: B

Rationale: Strict behaviorists, who adhere to behaviorism, believe that human behavior is primarily influenced by environmental factors. This perspective asserts that individuals' actions and responses are shaped by their interactions with the environment, learning experiences, and external stimuli. Choice A is incorrect because strict behaviorists do not focus on inherited factors but on how behavior is learned and shaped through environmental influences. Choice C is also incorrect as behaviorists do not believe in equal contributions of inherited and environmental factors; they emphasize environmental determinants. Choice D is incorrect as behaviorists have a clear stance that behavior is influenced by environmental stimuli and learning experiences.

4. Why is it particularly useful to study identical twins who were raised in different environments?

A. Differences in brain function can be easily identified.
B. Concordance rates tend to be higher.
C. It is possible that the genetics of twins who have been separated have changed in ways to explain any differences found.
D. It is possible that high concordance rates between identical twins reared together are due to their being treated more similarly than nonidentical twins.

Correct answer: D

Rationale: Studying identical twins raised in different environments allows researchers to understand the impact of genetics versus environmental factors on traits. Choice A is incorrect because differences in brain function can be influenced by a variety of factors and not solely by environmental differences. Choice B is incorrect as concordance rates tend to be higher in identical twins reared together due to shared genetics and environment. Choice C is incorrect because genetics do not change due to being raised in different environments.

5. 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 by 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 additional chromosome 21 disrupts the normal course of development and leads to the characteristics associated with Down syndrome.
