Psychology 101 Exam 3 Test

1. What does the genetic study of identical twins reared apart help to clarify?

Correct answer: C

Rationale: The correct answer is C: 'Interaction between genetics and environment.' The genetic study of identical twins reared apart helps in understanding how both genetics and environment play a role in shaping an individual's traits and behaviors. This type of study allows researchers to tease apart the effects of genetic inheritance from those of environmental influences. Choices A, B, and D are incorrect because the study of identical twins reared apart specifically focuses on the interplay between genetics and environment, rather than solely on differences in brain function, genetic influence on behavior, or the role of environmental factors alone.

2. Undercontrolled behavior tends to be seen in American children, whereas overcontrolled behavior is seen in Thai children.

Correct answer: C

Rationale: The correct answer is C: 'Undercontrolled behavior; overcontrolled behavior.' The question highlights a cultural difference in behavior tendencies between American and Thai children. American children are usually characterized by undercontrolled behavior, while Thai children tend to exhibit overcontrolled behavior. Choice A (Aggressive behavior; calm behavior) is incorrect as the question does not mention aggressive or calm behavior as the contrasting traits between the two groups. Choice B (Overcontrolled behavior; undercontrolled behavior) is incorrect because the described behavior patterns are reversed based on the question's context. Choice D (Equal behavioral traits in both cultures) is incorrect as the question explicitly states differing behavior patterns in American and Thai children.

3. Scientific research has demonstrated that the ________ parenting style is most likely to lead to healthy psychological development in children.

Correct answer: A

Rationale: The correct answer is A, authoritative. Authoritative parenting combines warmth and nurturing with reasonable limits and consistent discipline. This style promotes independence, self-regulation, and social competence in children, leading to healthy psychological development. Choice B, authoritarian parenting, is characterized by strict rules and harsh punishment without much warmth, which can lead to anxiety and lower self-esteem in children. Choice C, permissive parenting, involves few demands and little control, resulting in children lacking self-discipline and social skills. Choice D, neglectful/uninvolved parenting, is characterized by a lack of responsiveness to a child's emotional needs and can lead to various negative outcomes such as poor self-esteem and emotional issues.

4. What would a humanist most likely say about Manny's passivity?

Correct answer: B

Rationale: Humanists believe in the inherent goodness and potential of individuals. They would most likely say that Manny can become more assertive by improving his self-esteem and recognizing his abilities. Choice A is incorrect because humanists focus on self-actualization rather than deep-seated feelings of inferiority. Choice C is incorrect as it oversimplifies the issue by suggesting a training class can solve the problem without addressing underlying beliefs. Choice D is incorrect as it suggests a psychoanalytic approach, while humanists usually emphasize personal growth and self-improvement.

5. What does the diathesis-stress model entail?

Correct answer: B

Rationale: The diathesis-stress model proposes that mental disorders develop from a combination of genetic vulnerability (the diathesis) and environmental stressors. Choice A is incorrect because it states that stress alone can cause mental disorders, which is not in line with the model. Choice C is incorrect as it simplifies the model to genetic factors alone causing mental disorders. Choice D is incorrect as it suggests that environmental stressors do not play a role in the onset of mental disorders, which contradicts the essence of the diathesis-stress model.
