1. 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.

2. How does stress impact brain function?

• A. Stress has no effect on brain function.
• B. Stress can lead to changes in brain structure and function.
• C. Stress can improve brain function.
• D. Stress has no long-term impact on brain function.

Correct answer: B

Rationale: Stress can lead to changes in brain structure and function, affecting mental health and increasing the risk of disorders. Choice A is incorrect as stress does affect brain function. Choice C is incorrect as stress generally has negative impacts on brain function rather than improving it. Choice D is incorrect because stress can have long-term impacts on brain function through structural and functional changes.

3. Which neurotransmitter is reduced in both the manic and depressive phases of bipolar disorder?

• A. Acetylcholine
• B. Dopamine
• C. Norepinephrine
• D. Serotonin

Correct answer: D

Rationale: The correct answer is D, Serotonin. Serotonin levels are reduced during both the manic and depressive phases of bipolar disorder. Acetylcholine (choice A) is not typically linked to bipolar disorder. Dopamine (choice B) and norepinephrine (choice C) are more commonly associated with conditions like schizophrenia and depression, respectively, rather than bipolar disorder. Therefore, they are not the neurotransmitters reduced in both manic and depressive phases of bipolar disorder.

4. Infant characteristics ________.

• A. do not affect parental behavior.
• B. only affect parental behavior when psychopathology is present.
• C. are not influenced by biological factors.
• D. can influence the quality of attachment relationships.

Correct answer: D

Rationale: Infant characteristics can indeed influence the quality of attachment relationships. Parents often respond to their infants based on their characteristics, temperament, and needs. This interaction shapes the attachment bond between the parent and the child. Choices A, B, and C are incorrect because infant characteristics do have an impact on parental behavior and are influenced by various factors, including biological ones.

5. Which part of the superego develops from our experiences with rewards for proper behavior and tells us what we should do?

• A. Conscience
• B. Ego-ideal
• C. Regressing back to the anal stage
• D. Regressing back to the oral stage

Correct answer: B

Rationale: The correct answer is B, the Ego-ideal. The Ego-ideal is a subsystem of the superego that develops from experiences with rewards for proper behavior. It guides individuals on what they should do, setting standards and ideals for behavior. Choice A, Conscience, represents the part of the superego that focuses on what one should not do, based on experiences with punishment for improper behavior. Choices C and D, regressing back to the anal and oral stages respectively, are irrelevant to the development of the superego's components and are not related to experiences with rewards for proper behavior.
