1. New evidence suggests that __________.

A. there is very little cultural diversity in human development
B. environmental, but not personal, contexts shape development
C. development occurs in a neat, orderly sequence of stages unaffected by distinct contexts
D. people not only are affected by but also contribute to the contexts in which they develop Answer: D Page Ref: 6 Skill Level: Understand Topic: Basic Issues Difficulty Level: Difficult

Correct answer: D

Rationale: The correct answer is D because the statement aligns with the concept of reciprocal influences in human development. The new evidence suggests that individuals are not only influenced by the contexts in which they develop but also contribute to shaping those contexts. This idea highlights the dynamic and interactive nature of human development, emphasizing the bidirectional relationship between individuals and their environments.

2. __________ may heighten the effects of a high-fat diet.

A. Sex hormones
B. Over-the-counter medications
C. Free radicals
D. Low body weight

Correct answer: C

Rationale: Free radicals may contribute to oxidative stress, increasing the risk of conditions associated with a high-fat diet. When consuming a high-fat diet, the body may produce more free radicals, leading to oxidative damage. Sex hormones, over-the-counter medications, and low body weight do not directly heighten the effects of a high-fat diet like free radicals do.

3. In females, the twenty-third pair of chromosomes is labeled as __________.

A. an autosome
B. dizygotic
C. XX
D. XY

Correct answer: C

Rationale: In females, the twenty-third pair of chromosomes is indeed labeled as XX. This pair of chromosomes determines the biological sex of females. Choice A, 'an autosome,' is incorrect as autosomes refer to the non-sex chromosomes. Choice B, 'dizygotic,' is incorrect as it relates to twins. Choice D, 'XY,' is incorrect as it represents the chromosome pair found in males.

4. Which statement describes a strength of naturalistic observation?

A. It reflects the participants' everyday lives.
B. It permits comparisons of participants' responses.
C. Great depth and breadth of information can be obtained in a short time.
D. It grants each participant an equal opportunity to display the behavior of interest.

Correct answer: A

Rationale: Naturalistic observation reflects the participants' everyday lives because it involves observing individuals in their natural environments without any manipulation. This allows researchers to see how people behave in real-world settings and can provide valuable insights into their typical behavior patterns. Choice B is incorrect because naturalistic observation focuses on observing behavior in its natural setting rather than comparing responses between participants. Choice C is incorrect as naturalistic observation tends to provide rich, qualitative data rather than a large amount of information in a short time. Choice D is incorrect because in naturalistic observation, participants are observed as they naturally behave, which may not always lead to an equal opportunity for all participants to display the behavior of interest.

5. Under ethical standards, when is deception permitted in research studies?

A. if the participants are young enough that they would not understand the deception
B. if investigators satisfy institutional review boards that such practices are necessary
C. if researchers can observe participants from behind one-way mirrors
D. if the participants give informed consent and the researchers never reveal the real purpose of the study

Correct answer: B

Rationale: Ethical standards permit deception in research studies if investigators satisfy institutional review boards that such practices are necessary. Institutional review boards are responsible for ensuring that research studies comply with ethical guidelines and protect the welfare of study participants. Deception should only be used when necessary, and the board's approval indicates that safeguards are in place to minimize harm to participants. Choices A, C, and D are incorrect because ethical deception in research studies is not based on the age of participants, observing from behind mirrors, or obtaining informed consent without revealing the study's real purpose.
