1. By using which method of assignment of participants to treatment conditions, investigators increase the chances that participants' characteristics will be equally distributed across treatment groups?

• A. sequential
• B. random
• C. systematic
• D. correlational

Correct answer: B

Rationale: By using random assignment of participants to treatment conditions, investigators increase the chances that participants' characteristics will be equally distributed across treatment groups. Random assignment helps reduce the likelihood of bias in the selection process and ensures that any differences between groups are due to the treatment and not pre-existing group differences. Sequential, systematic, and correlational assignment methods do not provide the same level of assurance in distributing participants' characteristics equally across treatment groups.

2. Among preschoolers, __________ contributes to gains in emotional self-regulation.

• A. permissive child rearing
• B. authoritarian child rearing
• C. language
• D. family size

Correct answer: C

Rationale: Corrected Rationale: Language development plays a crucial role in emotional self-regulation in preschoolers. It enables children to express and manage their emotions effectively. Choices A and B, permissive and authoritarian child rearing styles, focus more on the parenting approach rather than the child's intrinsic development. Family size, as mentioned in choice D, does not directly contribute to gains in emotional self-regulation.

3. Which statement provides an example of an age-graded influence?

• A. Paul learned to play the violin at a young age.
• B. Jack enjoys hiking in the mountains.
• C. Sarah prefers reading mystery novels.
• D. Alex excels in mathematics.

Correct answer: A

Rationale: The corrected statement 'Paul learned to play the violin at a young age' provides an example of an age-graded influence. This is because learning to play the violin is a behavior that is typical or expected at a certain age, reflecting how age influences individuals' experiences and development. In contrast, choices B, C, and D do not directly relate to age-graded influences. Jack's enjoyment of hiking, Sarah's preference for reading mystery novels, and Alex's proficiency in mathematics are not inherently tied to age-related developmental influences.

4. 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.

5. Dr. Whiren studies how culture is transmitted to the next generation. Dr. Whiren’s research best aligns with the perspective of which theorist?

• A. Jean Piaget
• B. John Bowlby
• C. Lev Vygotsky
• D. Erik Erikson Answer: C Page Ref: 22 Skill Level: Apply Topic: Recent Theoretical Perspectives Difficulty Level: Difficult

Correct answer: C

Rationale: Dr. Whiren's study on how culture is transmitted to the next generation aligns best with the perspective of Lev Vygotsky. Vygotsky was a developmental psychologist who emphasized the importance of social interactions and cultural influences in shaping cognitive development. He believed that children learn through interactions with others and that culture plays a significant role in this learning process.
