1. Like Piaget's theory, the information-processing approach __________.

• A. divides development into stages
• B. views development as discontinuous
• C. regards people as actively making sense of their own thinking
• D. has much to say about nonlinear cognition, such as imagination and creativity

Correct answer: C

Rationale: The correct answer is C: 'regards people as actively making sense of their own thinking.' The information-processing approach, similar to Piaget's theory, focuses on how individuals actively process information, encode it, store it, and retrieve it to understand the world around them. Choices A and B are incorrect because the information-processing approach does not necessarily divide development into stages or view development as discontinuous. Choice D is incorrect because the information-processing approach is more concerned with cognitive processes like encoding, storage, and retrieval, rather than nonlinear cognition such as imagination and creativity.

2. The two main types of designs used in all research on human behavior are __________ and __________.

• A. observational; experimental
• B. correlational; experimental
• C. observational; correlational
• D. variable; observational Answer: B Page Ref: 31 Skill Level: Remember and limitations of each. Topic: Studying Development Difficulty Level: Easy

Correct answer: B

Rationale: The two main types of designs used in all research on human behavior are correlational and experimental. Correlational research examines the relationship between two or more variables without establishing causation, while experimental research involves manipulating one variable to observe the effect on another variable. These two types of designs are fundamental in understanding and studying human behavior.

3. Dr. Dias's research shows that the death of a spouse in old age is correlated with a decline in the surviving partner's physical health. Which conclusion is supported by this study?

• A. The death of a spouse causes a decline in the surviving partner's physical health.
• B. The death of a spouse is related to a decline in the surviving partner's physical health.
• C. A decline in a surviving partner's physical health can cause the death of a spouse.
• D. A third variable, such as memory loss, causes a surviving partner's decline in physical health following the death of a spouse.

Correct answer: B

Rationale: Dr. Dias's research findings indicate a correlation between the death of a spouse and a decline in the surviving partner's physical health. This correlation suggests a relationship between the two variables, but it does not necessarily imply a direct cause-and-effect relationship. Therefore, the correct conclusion supported by this study is option B - 'The death of a spouse is related to a decline in the surviving partner's physical health.' Option A is too direct in its causation claim, which is not proven by correlation alone. Option C reverses the cause and effect relationship suggested by the research. Option D introduces an unrelated third variable, which is not supported by the study's findings.

4. During Irina's first week of pregnancy, __________.

• A. heart muscles begin to develop
• B. the zygote multiplies and forms a blastocyst
• C. a primitive brain and spinal cord appear
• D. the embryo can move

Correct answer: B

Rationale: During the first week of pregnancy, the zygote (fertilized egg) undergoes rapid cell divisions and forms a blastocyst. This is a crucial stage where the cells differentiate and specialize, setting the foundation for the development of the embryo. It is during this time that the zygote implants itself into the uterine wall, initiating the process of pregnancy. Choices A, C, and D are incorrect because during the first week of pregnancy, the focus is on the initial development and multiplication of the zygote, not on the development of heart muscles, a primitive brain and spinal cord, or the embryo's ability to move.

5. Which country does not rank well on any key measure of children's health and well-being?

• A. Sweden
• B. Spain
• C. Australia
• D. The United States

Correct answer: D

Rationale: The United States is the correct answer as it ranks poorly in measures of children's health and well-being compared to other developed nations. According to the extract provided, the United States does not perform well in this aspect. Choices A, B, and C are incorrect as there is no information provided suggesting that Sweden, Spain, or Australia do not rank well on key measures of children's health and well-being.
