Psychological Exam

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. John Bowlby's attachment theory emphasized ________.

A. the social environment in forming attachments.
B. the quality of parental care in forming attachments.
C. the quality of early reinforcers and stimulation in forming attachments.
D. the necessity of independence from parental figures in forming attachments.

Correct answer: B

Rationale: John Bowlby's attachment theory emphasized the quality of parental care in forming attachments. This is because Bowlby believed that a child's early experiences with their primary caregiver, especially the quality of care and responsiveness received, significantly influence the child's ability to form secure attachments. Choice A is incorrect because while the social environment plays a role, Bowlby's theory focused more on the caregiver-child relationship. Choice C is incorrect as it does not capture the central role of parental care highlighted in Bowlby's theory. Choice D is also incorrect as Bowlby's theory actually emphasized the importance of a secure attachment to parental figures for healthy emotional development.

3. What are influences that are unusual events with a major impact on individual lives because they disrupt the expected sequence of the life cycle?

A. Nonnormative influences
B. Normative history-graded influence
C. Normative age-graded influence
D. Sensitive period

Correct answer: A

Rationale: Nonnormative influences refer to unusual events that have a significant impact on individuals' lives by disrupting the typical life cycle. They are events that are not typical for a specific age or cohort. Normative history-graded influences (choice B) are common influences shared by a specific generation due to historical circumstances. Normative age-graded influences (choice C) are typical events that occur at a particular age for most people. A sensitive period (choice D) is a biologically determined time during which specific experiences have a lasting impact on development.

4. What is the relationship between socioeconomic status and the prevalence of abnormal behavior?

A. Socioeconomic status does not affect the prevalence of abnormal behavior.
B. There is a positive correlation between low socioeconomic status and a higher prevalence of abnormal behavior.
C. Higher socioeconomic status is associated with a lower prevalence of abnormal behavior.
D. Socioeconomic status and the prevalence of abnormal behavior are unrelated.

Correct answer: B

Rationale: The correct answer is B. There is a positive correlation between low socioeconomic status and a higher prevalence of abnormal behavior. Individuals with lower socioeconomic status may face more stressors, reduced access to mental health resources, and other challenges that can contribute to a higher prevalence of abnormal behavior. Choice A is incorrect because socioeconomic status does affect the prevalence of abnormal behavior. Choice C is incorrect because higher socioeconomic status is not associated with a lower prevalence of abnormal behavior. Choice D is incorrect as there is a clear relationship between socioeconomic status and the prevalence of abnormal behavior.

5. The genetic influences that determine behavior may never be fully understood due to ________

A. the ease of researching to differentiate between the effects of the environment and the effects of genes.
B. the likelihood that most behaviors are determined by the interaction of many genes and the environment.
C. the tendency to rely 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 a complex interaction of many genes and the environment. Choice A is incorrect because it states that it is easy to differentiate between the effects of the environment and genes, which is not the case. Choice C is incorrect because although twin studies are commonly used in genetic research, this alone does not hinder the full understanding of genetic influences on behavior. Choice D is incorrect because even though we have some understanding of how genes impact brain chemistry, this does not mean that we fully understand the genetic influences on behavior.
