1. 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 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 extra copy of chromosome 21, also known as trisomy 21, leads to the characteristic features and health problems associated with Down syndrome.

2. What is the diathesis-stress model of psychopathology?

A. The idea that stress is the primary cause of psychopathology.
B. A model that focuses solely on genetic predispositions.
C. A theory that involves only environmental factors in the development of disorders.
D. A person must have both a vulnerability for a disorder and exposure to stressors to develop the disorder.

Correct answer: D

Rationale: The diathesis-stress model of psychopathology posits that individuals must have a vulnerability or predisposition to a disorder (diathesis) and be exposed to stressful environmental factors for the disorder to manifest. This model emphasizes the interaction between genetic or biological vulnerabilities (diathesis) and environmental stressors. Choice A is incorrect because the model does not suggest that stress is the sole cause of psychopathology. Choice B is incorrect as the model considers both genetic predispositions and environmental stressors. Choice C is incorrect because the diathesis-stress model acknowledges the role of both genetic and environmental factors in the development of disorders.

3. What are psychology's intellectual parents?

A. Physics and physiology.
B. Philosophy and physiology.
C. Chemistry and physics.
D. Philosophy and chemistry.

Correct answer: B

Rationale: Psychology's intellectual parents are philosophy and physiology. Philosophy contributed to the early development of psychology by exploring questions about the mind and behavior, while physiology provided a scientific foundation for understanding the biological aspects of human psychology. Choices A, C, and D are incorrect as they do not accurately represent the disciplines that significantly influenced the emergence of psychology as a distinct field of study.

4. What is the term for the age of an unborn baby, usually dated from the first day of an expectant mother's last menstrual cycle?

A. Mental age
B. Chronological age
C. Functional age
D. Gestational age

Correct answer: D

Rationale: The correct answer is D, Gestational age. Gestational age is calculated from the first day of the expectant mother's last menstrual cycle, providing an estimate of how far along the pregnancy is. Mental age (choice A), refers to an individual's level of cognitive functioning in relation to others of the same age group. Chronological age (choice B) is a person's actual age in years. Functional age (choice C) refers to how well a person is able to perform various activities compared to their chronological age.

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

A. authoritative
B. authoritarian
C. permissive
D. neglectful/uninvolved

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.
