Why is it particularly useful to study identical twins who were raised in different environments?
- A. Differences in brain function can be easily identified.
- B. Concordance rates tend to be higher.
- C. It is possible that the genetics of twins who have been separated have changed in ways to explain any differences found.
- D. It is possible that high concordance rates between identical twins reared together are due to their being treated more similarly than nonidentical twins.
Correct Answer: D
Rationale: Studying identical twins raised in different environments allows researchers to understand the impact of genetics versus environmental factors on traits. Choice A is incorrect because differences in brain function can be influenced by a variety of factors and not solely by environmental differences. Choice B is incorrect as concordance rates tend to be higher in identical twins reared together due to shared genetics and environment. Choice C is incorrect because genetics do not change due to being raised in different environments.

According to Freud, a person who does not appropriately resolve each psychosexual stage would be _________ at that stage.
- A. defended
- B. fixated
- C. repressed
- D. displaced
Correct Answer: B
Rationale: According to Freud's theory of psychosexual development, if a person does not resolve a particular stage successfully, they become fixated at that stage. This fixation can lead to behavior patterns characteristic of that stage in later life. In this context, 'defended' is incorrect because it does not align with Freud's theory of fixation. 'Repressed' is not the correct choice as it refers to the unconscious suppression of thoughts or desires. 'Displaced' involves redirecting emotions from their original source to a substitute target, which is not the concept Freud associated with unresolved psychosexual stages.
A lack of social skills, poor school performance, and moodiness have all been associated with which of the following parenting styles?
- A. Authoritarian
- B. Permissive/indulgent
- C. Authoritative
- D. Neglectful/uninvolved
Correct Answer: D
Rationale: The correct answer is D, Neglectful/uninvolved. This parenting style is associated with a lack of social skills, poor school performance, and moodiness due to the lack of parental involvement and emotional support. Authoritarian parenting (choice A) is characterized by strict rules and high demands, not necessarily linked to these issues. Permissive/indulgent parenting (choice B) involves few rules and high responsiveness, which may not directly lead to these problems. Authoritative parenting (choice C) combines high demands with emotional support and is actually linked to positive outcomes such as good school performance and social skills.
How does the biopsychosocial model differ from the biomedical model?
- A. The biopsychosocial model focuses solely on the biological aspects of disease.
- B. The biopsychosocial model includes biological, psychological, and social factors, whereas the biomedical model focuses on only biological factors.
- C. The biopsychosocial model is outdated and has been replaced by the biomedical model.
- D. The biopsychosocial model is identical to the biomedical model.
Correct Answer: B
Rationale: The biopsychosocial model differs from the biomedical model by considering biological, psychological, and social factors in understanding health and illness. Choice A is incorrect because the biopsychosocial model does not solely focus on biological aspects. Choice C is incorrect as the biopsychosocial model is not outdated but rather offers a more comprehensive approach. Choice D is incorrect as the two models are distinct in their considerations of factors beyond biology.
Why is it difficult to determine the nature of the relationship between divorce and the psychological functioning of family members?
- A. Cause and effect cannot be determined as preexisting behavioral abnormalities in either the parents or the children may make divorce more likely.
- B. The findings have been too inconsistent to draw any conclusions.
- C. While the effects of divorce are negative on children, the effects on the spouses are generally positive.
- D. Due to modern acceptance of divorce, there has been an ongoing decrease in the negative effects of divorce.
Correct Answer: A
Rationale: The correct answer is A because it highlights a crucial factor that makes it challenging to establish a clear cause and effect relationship between divorce and the psychological functioning of family members. Preexisting behavioral abnormalities in either the parents or the children may influence both the likelihood of divorce and the psychological functioning of family members. Choice B is incorrect as it generalizes the findings without specifying the key issue of preexisting conditions. Choice C is incorrect as it oversimplifies the effects of divorce on family members. Choice D is incorrect as it presents a broad statement without addressing the complexities involved in determining the effects of divorce.
Freud's psychosexual stage that occurs between the ages of 3 and 5 and includes the Oedipal period is the _________ stage.
- A. Oral
- B. Anal
- C. Phallic
- D. Genital
Correct Answer: C
Rationale: The correct answer is C: Phallic. Freud's psychosexual stage that occurs between ages 3 and 5 and includes the Oedipal period is the phallic stage. This stage is characterized by the Oedipus complex for boys and the Electra complex for girls. Choices A, B, and D are incorrect because the oral stage typically occurs during the first year of life, the anal stage occurs around ages 2 to 3, and the genital stage is the final stage in Freud's theory of psychosexual development.
