1. In an experiment, the independent variable __________.

• A. is the one the investigator expects to be influenced by another variable
• B. is the one the investigator expects to cause changes in another variable
• C. cannot be manipulated or controlled by the researcher
• D. is the number that describes how two measures are associated with each other

Correct answer: B

Rationale: In an experiment, the independent variable is the one that the investigator expects to cause changes in another variable. It is the factor that is deliberately manipulated or changed by the researcher to observe its effects on the dependent variable. The purpose of manipulating the independent variable is to study its impact on the outcome, allowing researchers to establish cause-and-effect relationships in their investigations. Choice A is incorrect because the independent variable is not influenced but rather influences another variable. Choice C is incorrect as the independent variable is intentionally manipulated by the researcher. Choice D is incorrect as it refers to a different concept unrelated to the independent variable in an experiment.

2. School-age children master concrete operational tasks ________.

• A. all at once
• B. gradually, in a continuum of acquisition
• C. much later than Piaget believed
• D. after they master abstract thinking

Correct answer: B

Rationale: Correct answer: School-age children master concrete operational tasks gradually, in a continuum of acquisition. Piaget's theory suggests that children develop cognitive abilities in stages, with concrete operational tasks being acquired gradually as part of this process. Choices A, C, and D are incorrect because concrete operational tasks are not typically mastered all at once, much later than Piaget believed, or necessarily after mastering abstract thinking.

3. Nine-year-old Krista gives part of her allowance to charity and collects canned goods for the food bank through her scout troop. Krista is developing __________.

• A. pride
• B. empathy
• C. guilt
• D. inferiority

Correct answer: B

Rationale: The correct answer is B: empathy. Empathy is the ability to understand and share the feelings of others, which is a crucial social development in childhood. In this scenario, Krista's actions of giving to charity and collecting goods for the food bank demonstrate her growing empathy towards those in need. Choice A, pride, does not capture the essence of understanding and sharing others' feelings. Choice C, guilt, is not appropriate as there is no indication that Krista feels guilty about her actions. Choice D, inferiority, is unrelated to the positive behavior displayed by Krista.

4. According to Erikson, __________ occurs when aging adults feel they have made many wrong decisions, yet time is too short to find an alternate route to integrity.

• A. mistrust
• B. despair
• C. stagnation
• D. isolation

Correct answer: B

Rationale: According to Erikson's theory of psychosocial development, despair is the stage that aging adults face when they reflect on their life and feel they have not achieved their goals, with little time left to correct their mistakes. Mistrust (choice A) is associated with infancy, stagnation (choice C) with middle adulthood, and isolation (choice D) with young adulthood, and are not relevant to the described scenario of aging adults reflecting on their life decisions.

• A. microsystem
• B. mesosystem
• C. exosystem
• D. macrosystem Answer: A Page Ref: 23 Skill Level: Apply Topic: Recent Theoretical Perspectives Difficulty Level: Moderate

Correct answer: A

Rationale: According to ecological systems theory, interactions between Marina and her child, Tyler, occur in the microsystem. The microsystem refers to the immediate social context in which an individual lives, such as interactions with family members, friends, and teachers. Marina and Tyler's interactions within their family unit would be considered part of the microsystem.
