1. Although great diversity characterizes the interests and concerns of investigators who study development, they share a single goal: to identify __________.

• A. genetic factors that contribute to longevity
• B. environmental factors that contribute to disease and illness
• C. those factors that lead to abnormal development in children and adolescents
• D. those factors that influence consistencies and transformations in people from conception to death

Correct answer: D

Rationale: The correct answer is D because investigators who study development aim to identify the factors that influence consistencies and transformations in people from conception to death. This goal encompasses various domains such as physical, cognitive, emotional, and social development, highlighting the comprehensive nature of developmental research. Choices A, B, and C are incorrect as they do not align with the overarching goal of developmental researchers, which is to understand the factors influencing individuals throughout their lifespan, rather than focusing solely on genetic factors, environmental factors related to disease, or abnormal development in specific age groups.

2. In an experimental study examining whether the way angry encounters end affects children's emotional reactions, the dependent variable would be the __________.

• A. way the angry encounters end
• B. amount of unresolved anger
• C. frequency of angry encounters
• D. children's emotional reactions

Correct answer: D

Rationale: In an experimental study examining whether the way angry encounters end affects children's emotional reactions, the dependent variable would be the children's emotional reactions. The dependent variable is the outcome being measured or tested in an experiment. In this study, the researchers are trying to understand how the way angry encounters end influences children's emotions. Therefore, the emotional reactions of the children would be the dependent variable that is being studied and measured in relation to the way angry encounters end. Choices A, B, and C are not the dependent variable in this scenario. While they may be related factors, the main focus of the study is on how the way angry encounters end impacts children's emotional reactions, making children's emotional reactions the dependent variable.

3. If learning has occurred in classical conditioning, and the neutral stimulus by itself produces a response similar to the reflexive response, the neutral stimulus is then called a __________.

• A. neutral response
• B. conditioned stimulus
• C. conditioned response
• D. reinforcer

Correct answer: B

Rationale: In classical conditioning, when a neutral stimulus triggers the reflexive response, it becomes a conditioned stimulus. Therefore, the correct term for the neutral stimulus that now elicits a response is a conditioned stimulus. Choices A, C, and D are incorrect: A neutral response is not a standard term in classical conditioning; a conditioned response is the learned response to the conditioned stimulus, not the neutral stimulus itself; a reinforcer is a stimulus that follows a behavior and increases the likelihood of that behavior happening again, which is not the same as a conditioned stimulus.

4. The harm done by teratogens __________.

• A. is straightforward and predictable
• B. is usually apparent at birth
• C. rarely goes beyond physical damage
• D. depends on age at the time of exposure

Correct answer: D

Rationale: The harm done by teratogens depends on the age at the time of exposure. This means that the effects may vary depending on the developmental stage of the fetus when exposed to the teratogen. Teratogens can have different impacts at different stages of pregnancy, leading to a range of potential outcomes in terms of physical and/or cognitive development. Choices A, B, and C are incorrect because the harm caused by teratogens is not straightforward, may not be apparent at birth, and can go beyond physical damage, affecting cognitive development as well.

5. Unlike adults, newborn babies __________.

• A. have a limited sense of smell
• B. see nearby objects most clearly
• C. prefer unfamiliar voices to familiar ones
• D. see unclearly across a wide range of distances

Correct answer: B

Rationale: Unlike adults, newborn babies see nearby objects most clearly. This is due to the fact that newborns have a limited ability to focus their eyes on objects that are farther away. Their visual acuity is not fully developed at birth, leading to clearer vision of objects situated at a close distance. Choice A is incorrect because newborn babies have a well-developed sense of smell. Choice C is incorrect as newborns typically show a preference for familiar voices, such as their mother's voice. Choice D is incorrect as newborns do not see unclearly across a wide range of distances; rather, their vision is clearer for nearby objects.
