1. 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.

2. Rita shows better control over her eating habits at 2.5 years than her brother Richard did at the same age. Why?

• A. Girls are naturally smarter than boys.
• B. Second-born children learn faster.
• C. Girls have better fine motor skills.
• D. Boys have better gross motor skills.

Correct answer: D

Rationale: The correct answer is D because boys typically develop gross motor skills, like running and jumping, more quickly than girls. This can explain why Richard may have had less control over his eating habits compared to Rita at the same age. Choices A, B, and C are incorrect because they do not address the specific developmental aspect related to eating habits control mentioned in the question.

3. What is extinction, and how might it be used in treating a disorder?

• A. Extinction strengthens the conditioned response by continuously pairing the conditioned stimulus with the unconditioned stimulus.
• B. Extinction is the process of eliminating a conditioned response by repeatedly presenting the conditioned stimulus without the unconditioned stimulus.
• C. Extinction is ineffective and is not used in treating disorders.
• D. Extinction is the process of intensifying the conditioned response by pairing the conditioned stimulus with a stronger unconditioned stimulus.

Correct answer: B

Rationale: Extinction is the process of eliminating a conditioned response by repeatedly presenting the conditioned stimulus without the unconditioned stimulus. This process helps in reducing or eliminating undesired behaviors or responses. Choice A is incorrect because extinction weakens the conditioned response by breaking the association between the conditioned stimulus and the unconditioned stimulus. Choice C is incorrect as extinction is a widely used technique in behavioral therapies for treating disorders. Choice D is incorrect as extinction aims to reduce the conditioned response, not intensify it.

4. 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.

5. Dr. Fox studies the causes of depression. In other words, she looks at factors that play a role in the ________ of depression.

• A. etiology
• B. epidemiology
• C. prevalence
• D. resiliency

Correct answer: A

Rationale: The correct answer is A, 'etiology.' Etiology specifically deals with the causes or origins of diseases like depression. Choice B, 'epidemiology,' focuses on the patterns, causes, and effects of health and disease conditions in defined populations. Choice C, 'prevalence,' refers to the proportion of a population found to have a condition. Choice D, 'resiliency,' relates to the ability to recover from or adjust to challenges.
