1. What is the traditional cutoff in diagnosing intellectual disability?

A. IQ score below 80
B. IQ score below 70
C. IQ score below 60
D. IQ score below 50

Correct answer: B

Rationale: The traditional cutoff for diagnosing intellectual disability is an IQ score below 70. An IQ score below 70 is generally considered as the threshold for diagnosing intellectual disability. Choices A, C, and D are incorrect as they do not reflect the commonly accepted cutoff point for diagnosing intellectual disability.

2. Colleen found herself attracted to her psychology instructor. She would frequently go by his office just to be near him. When he didn't respond to her advances, Colleen eventually told him that she had thoughts of killing herself so that he would spend time trying to counsel her. What personality disorder best describes Colleen's thinking and behavior?

A. Borderline personality disorder
B. Schizoid personality disorder
C. Schizotypal personality disorder
D. Antisocial personality disorder

Correct answer: A

Rationale: Colleen's behavior of seeking attention and manipulating others by threatening self-harm to elicit a response from her psychology instructor aligns with the characteristics of borderline personality disorder. This disorder is characterized by unstable relationships, impulsive actions, and efforts to avoid real or imagined abandonment. Choices B, C, and D are incorrect because they do not match Colleen's behavior as described in the scenario. Schizoid personality disorder is characterized by a lack of interest in social relationships, Schizotypal personality disorder involves social anxiety and odd behavior, and Antisocial personality disorder is characterized by a disregard for others' feelings and violating their rights.

3. The understanding of genetic influences on behavior may never be fully achieved due to ________.

A. the ease of researching to differentiate between the effects of the environment and genes.
B. the likelihood that most behaviors are determined by the interaction of many genes and the environment.
C. the reliance on twin studies in genetic research.
D. our significant understanding of how genes impact brain chemistry.

Correct answer: B

Rationale: The correct answer is B because most behaviors are influenced by the interaction of multiple genes and the environment. Choice A is incorrect because it suggests that researching the effects of the environment and genes is easy, which is not the case. Choice C is incorrect as it focuses on a specific method (twin studies) rather than the broader concept of gene-environment interaction. Choice D is incorrect as the statement implies a high level of understanding that contradicts the idea that genetic influences on behavior may never be fully understood.

4. In __, the individual can't recall everything about a certain period of time.

A. Systematized amnesia
B. Selective amnesia
C. Collective amnesia
D. Localized amnesia

Correct answer: D

Rationale: Localized amnesia refers to the inability to recall all events during a specific period of time. This type of amnesia is characterized by the loss of memories related to a particular incident or period, while other memories remain intact. Choices A, B, and C are incorrect because they refer to different types of amnesia. Systematized amnesia is a term used to describe a selective loss of memory related to a specific category of information or knowledge. Selective amnesia involves the conscious or unconscious blocking out of specific memories, often due to psychological reasons. Collective amnesia pertains to a lack of shared memory or historical awareness within a group or society.

5. In order for one to have a recessive trait (e.g., having red hair), the person must receive?

A. At least one copy of a recessive gene from a parent
B. Two copies of a recessive gene, one from each parent
C. At least one copy of a recessive gene and at least one copy of a dominant gene
D. At least two copies of a recessive gene from one parent

Correct answer: B

Rationale: Recessive traits are expressed when an individual inherits two copies of the recessive gene, one from each parent. Therefore, the correct answer is B. Choice A is incorrect as one copy of a recessive gene is not sufficient to display a recessive trait. Choice C is incorrect because having at least one copy of a dominant gene is unrelated to expressing a recessive trait. Choice D is incorrect because two copies of a recessive gene must come from both parents, not just one.
