1. Currently, the most widely used potent teratogen is __________.

• A. aspirin
• B. diethylstilbestrol (DES)
• C. thalidomide
• D. isotretinoin

Correct answer: D

Rationale: The correct answer is D, isotretinoin. Isotretinoin is a medication commonly used to treat severe acne, but it is a potent teratogen, meaning it can cause severe birth defects if taken during pregnancy. Aspirin (choice A) is not a widely used potent teratogen. Diethylstilbestrol (DES) (choice B) was a known teratogen, but it is not currently widely used. Thalidomide (choice C) was another historical teratogen, but it is also not currently widely used. Therefore, isotretinoin is the most relevant answer as it is a commonly used medication that poses a high risk of birth defects if used during pregnancy.

2. Dr. McBride wants to know if the teacher's use of encouragement in the classroom affects the children's self-esteem. To assign children to treatment conditions, Dr. McBride should __________.

• A. carefully distribute the children according to their test scores
• B. divide the children so each group has an equal number of boys and girls
• C. draw the children's names out of a hat
• D. assign the quieter children to the same treatment condition

Correct answer: C

Rationale: Drawing the children's names out of a hat is a way to randomly assign them to treatment conditions. Random assignment helps to ensure that any differences in self-esteem that may be observed in the study are not due to pre-existing characteristics of the children. This method helps to establish a cause-and-effect relationship between the teacher's use of encouragement and the children's self-esteem. Choice A is incorrect because assigning children based on test scores may introduce bias into the study. Choice B is incorrect as balancing gender is not relevant to the research question. Choice D is incorrect as it introduces a bias by selecting a specific group of children based on a characteristic unrelated to the study objective.

3. Vygotsky's emphasis on culture and social experience led him to __________.

• A. understand the interaction between biological factors and social influences in cognitive development
• B. overemphasize the role of heredity in cognitive change
• C. emphasize children's independent efforts to make sense of their world
• D. place too much emphasis on children's capacity to shape their own development

Correct answer: A

Rationale: Vygotsky's emphasis on culture and social experience did not lead him to neglect the biological side of development. Instead, he believed that biological factors and social influences interact to shape cognitive development. Choice A is correct because it reflects Vygotsky's view that biological factors and social experiences work together in cognitive development. Choices B, C, and D are incorrect as Vygotsky's emphasis was not on overemphasizing heredity, focusing solely on independent efforts of children, or placing too much emphasis on children's capacity to shape their own development.

4. Which mother is most likely to have had inadequate prenatal care?

• A. Lupe, age 25
• B. Marissa, age 32
• C. Rotunda, age 16
• D. Janette, age 40

Correct answer: C

Rationale: Rotunda, age 16, is the most likely to have had inadequate prenatal care due to her young age and possibly limited access to healthcare resources and support. Adolescents are at higher risk for inadequate prenatal care compared to older mothers due to various factors such as lack of awareness, financial constraints, and inconsistent health behaviors. Young mothers may face challenges in seeking proper prenatal care due to reasons like lack of knowledge, fear of judgment, or limited financial means. Older mothers like Lupe, Marissa, and Janette are less likely to have inadequate prenatal care compared to a younger mother like Rotunda, as they may have more access to resources, experience, and support systems.

5. The information-processing perspective __________.

• A. examines separate aspects of thinking
• B. fails to consider biological influences on cognitive development
• C. applies only to children in cultures having formal schooling
• D. focuses on overall cognitive change

Correct answer: A

Rationale: The information-processing perspective focuses on how individuals process, store, and retrieve information. Choice A, 'examines separate aspects of thinking,' accurately reflects this perspective. The other choices are incorrect. Choice B is incorrect because the information-processing perspective does consider biological influences on cognitive development. Choice C is incorrect as this perspective is not limited to children in cultures with formal schooling. Choice D is incorrect as the information-processing perspective does not focus on overall cognitive change, but rather on the specific processes involved in information processing.
