1. 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.

2. What is the result when a single zygote separates into two parts, each developing into a separate individual?

• A. Dizygotic twin
• B. Monozygotic twin
• C. Fraternal twin
• D. Nonidentical twin

Correct answer: B

Rationale: The correct answer is B, Monozygotic twin. A monozygotic twin, also known as an identical twin, is the result when a single zygote splits into two parts, leading to the development of two genetically identical individuals. Choices A, C, and D are incorrect because they do not accurately describe the scenario where a single zygote splits into two parts to form identical twins. Dizygotic twin (Choice A) refers to fraternal twins, which result from two separate eggs fertilized by two different sperm cells. Fraternal twin (Choice C) is another term for dizygotic twins, arising from two separate zygotes. Nonidentical twin (Choice D) is a synonymous term for dizygotic or fraternal twins, indicating that they are not genetically identical.

3. With which of the following statements would a behaviorist agree?

• A. Conscious experiences can be studied in an objective, precise way.
• B. In order to understand behavior, one must understand the motives behind the behavior.
• C. Behavior can only be explained in terms of phenomenology, that is, an individual's interpretation of experience.
• D. Psychology should be the science of behavior that can be observed by others.

Correct answer: D

Rationale: The correct answer is D. Behaviorists argue that psychology should focus on observable behavior that can be studied objectively. Choice A is incorrect because behaviorists do not typically focus on conscious experiences, as they are not directly observable. Choice B is incorrect because behaviorists emphasize that behavior can be understood without delving into internal motives. Choice C is incorrect as behaviorists do not exclusively explain behavior through an individual's interpretation of experience; they focus on observable actions and reactions.

4. Children raised in orphanages tend to have ________.

• A. more cortical gray matter than those raised by their parents.
• B. less cortical gray matter than those raised by their parents.
• C. more friendships than those raised by their parents.
• D. fewer friendships than those raised by their parents.

Correct answer: B

Rationale: The correct answer is B: 'less cortical gray matter than those raised by their parents.' Studies have shown that children raised in orphanages tend to have less cortical gray matter compared to those raised by their parents. This is due to the lack of individualized care, attention, and stimulation that can negatively impact brain development. Choices A, C, and D are incorrect because there is no direct correlation between cortical gray matter and the number of friendships when comparing children raised in orphanages and those raised by their parents.

5. Freud's view of mental disorders was that they were a result of ________.

• A. unresolved conflicts between the id, the ego, and the superego.
• B. genetic abnormalities that influence people's ability to cope with their environment.
• C. problematic tendencies we develop while dealing with our early interpersonal environments.
• D. learned maladaptive behaviors that were rewarded with attention.

Correct answer: A

Rationale: Freud believed that mental disorders were a result of unresolved conflicts between the id, ego, and superego. This concept is central to Freud's psychoanalytic theory, where conflicts between these three components of personality lead to psychological distress. Choice B is incorrect because Freud focused more on unconscious conflicts rather than genetic abnormalities. Choice C is incorrect as it refers to later psychodynamic theories rather than Freud's specific view. Choice D is incorrect as Freud's perspective does not emphasize learned behaviors as the primary cause of mental disorders.
