behaviors that deviate from the norm are

ATI RN

Exam 4 Psychology

1. Behaviors that deviate from the norm are?

A. Always seen as a disorder if they violate social norms
B. Considered a disorder regardless of culture
C. Typically seen as a disorder when they impair functioning
D. Never considered as a sign of abnormality

Correct answer: C

Rationale: Behaviors that deviate from the norm are typically considered disorders when they impair functioning. Choice A is incorrect because not all behaviors that deviate from the norm are considered disorders; they need to impair functioning. Choice B is incorrect because the cultural context plays a significant role in determining what is considered abnormal. Choice D is incorrect because behaviors that deviate from the norm can indeed be considered signs of abnormality, especially if they impair functioning.

2. What are substances, such as viruses and drugs, that can cause birth defects?

A. Teratogens
B. Placenta
C. Parturition
D. Androgens

Correct answer: A

Rationale: Teratogens are substances that can cause birth defects, especially if exposure occurs during critical periods of development. In this context, teratogens refer to external agents that can interfere with the development of the embryo or fetus, leading to structural or functional abnormalities. Choice B, Placenta, is incorrect as it is an organ that develops during pregnancy to provide nutrients and oxygen to the fetus and remove waste products. Choice C, Parturition, refers to the process of giving birth and is not related to substances that cause birth defects. Choice D, Androgens, are male sex hormones and are not associated with causing birth defects.

3. 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.

4. 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.

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

A. Differences in brain function
B. Genetic influence on behavior
C. Interaction between genetics and environment
D. The role of environmental factors alone

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.
