1. To overcome some of the limitations of traditional developmental designs, investigators sometimes use __________ designs, in which they conduct several similar cross-sectional or longitudinal studies.

• A. sequential
• B. experimental
• C. correlational
• D. quasi-experimental Answer: A Page Ref: 36 Skill Level: Remember Topic: Studying Development Difficulty Level: Easy

Correct answer: A

Rationale: Sequential designs involve conducting multiple similar cross-sectional or longitudinal studies to overcome limitations of traditional developmental designs. By combining different types of study designs, researchers can gain a more comprehensive understanding of development over time. This approach allows for more robust conclusions and can help address potential confounding variables that may impact the results.

2. Shamona, a pregnant mother in Flint, Michigan, is concerned about the drinking water, which shows high levels of lead. Shamona should know that high levels of prenatal lead exposure are related to __________.

• A. facial abnormalities and heart defects
• B. defects of the genitals and urinary tract
• C. low birth weight and brain damage
• D. a variety of childhood cancers

Correct answer: C

Rationale: High levels of prenatal lead exposure are related to low birth weight and brain damage. Lead exposure during pregnancy can have harmful effects on the developing fetus, leading to complications such as decreased birth weight and potential long-term brain damage. Choices A, B, and D are incorrect because they do not directly correlate with the known effects of prenatal lead exposure. While lead exposure can indeed cause a variety of health issues, such as heart defects and urinary tract problems, the primary concerns related to prenatal exposure are low birth weight and brain damage.

3. Dr. George predicted that positive reinforcement would increase prosocial behavior in preschoolers. Dr. George's prediction is an example of a __________.

• A. theory
• B. research question
• C. hypothesis
• D. research design

Correct answer: C

Rationale: Dr. George's prediction that positive reinforcement would increase prosocial behavior in preschoolers is an example of a hypothesis. A hypothesis is a specific, testable prediction about the relationship between variables based on existing knowledge or theories. In this case, Dr. George is making a prediction about the effect of positive reinforcement on prosocial behavior, which can be tested through research. Choice A, 'theory,' is incorrect because a theory is a broader explanation that integrates a range of findings and observations. Choice B, 'research question,' is incorrect as it refers to an inquiry that asks about the relationship between variables but lacks the specificity and testability of a hypothesis. Choice D, 'research design,' is incorrect as it pertains to the overall strategy or plan for conducting a research study, not the specific prediction Dr. George made.

4. Lanugo ________.

• A. permits food and oxygen to reach the organism
• B. provides the fetus a cushion against jolts caused by the mother's movements
• C. helps regulate the fetus's body temperature
• D. helps the vernix stick to the skin

Correct answer: D

Rationale: Lanugo helps the vernix stick to the skin. Vernix is a waxy substance that covers the fetus's skin during pregnancy. Lanugo is a fine, downy hair that helps to anchor the vernix to the skin, providing protection and nourishment to the developing fetus. Choices A, B, and C are incorrect as they do not accurately describe the role of lanugo in prenatal development.

5. Which statement about the newborn baby's appearance is true?

• A. Girls tend to be slightly longer and heavier than boys.
• B. Their round faces and big eyes make adults feel like picking them up.
• C. The trunk is large in comparison to the head, and the legs are straight.
• D. On average, they are 18 inches long and 5½ pounds in weight.

Correct answer: C

Rationale: The correct statement about the newborn baby's appearance is that the trunk is large in comparison to the head, and the legs are straight. This is a common characteristic of newborn babies as their proportions are different from adults. Choice A is incorrect as there is no consistent trend of girls being longer and heavier than boys at birth. Choice B is incorrect as the perception of adults wanting to pick up babies is subjective and not a universal truth. Choice D is incorrect as the average length and weight provided may not apply to all newborn babies, as there can be variations.
