1. In the United States, the second leading cause of neonatal mortality is __________, which is largely preventable.

• A. malnutrition
• B. physical abnormality
• C. low birth weight
• D. sudden infant death syndrome

Correct answer: C

Rationale: The second leading cause of neonatal mortality in the United States is low birth weight, which is largely preventable through proper prenatal care, nutrition, and health interventions. Low birth weight infants are at higher risk for various health complications and mortality, making it an important issue to address in maternal and child health programs. Malnutrition (choice A) can contribute to low birth weight but is not the direct cause of neonatal mortality. Physical abnormality (choice B) can be a factor in some cases but is not the second leading cause overall. Sudden infant death syndrome (choice D) refers to unexplained deaths of seemingly healthy babies and is not related to low birth weight as a leading cause of neonatal mortality.

2. Dr. Singh believes that a basic psychosocial conflict, which is resolved along a continuum from positive to negative, determines healthy or maladaptive outcomes at each stage of development. Dr. Singh's beliefs are aligned with those of which theorist?

• A. G. Stanley Hall
• B. Sigmund Freud
• C. Erik Erikson
• D. B. F. Skinner

Correct answer: C

Rationale: Dr. Singh's beliefs align with Erik Erikson's psychosocial theory of development. Erikson proposed that individuals go through a series of psychosocial stages, with each stage characterized by a basic conflict that must be resolved to achieve healthy development. This conflict is resolved along a continuum from positive to negative outcomes. Choice A, G. Stanley Hall, is incorrect as his work focused on adolescence and evolutionary psychology. Choice B, Sigmund Freud, is incorrect as his psychoanalytic theory is more focused on the unconscious mind and psychosexual stages. Choice D, B. F. Skinner, is incorrect as he is associated with behaviorism and operant conditioning, which is different from Erikson's psychosocial theory.

3. Which Apgar criterion can be more difficult to apply to newborns of all races?

• A. pink color
• B. reflex irritability
• C. limp muscle tone
• D. strong breathing

Correct answer: D

Rationale: Among the Apgar criteria, the pink color (choice A), reflex irritability (choice B), and limp muscle tone (choice C) are relatively easy to assess in newborns of all races. However, the criterion that can be more difficult to apply to newborns of all races is strong breathing (choice D). This is because evaluating the strength of a newborn's breathing can be more subjective and require careful observation. Unlike the other criteria that have more visible and objective indicators, assessing the strength of breathing might vary based on the observer's interpretation, making it more challenging to apply universally.

4. What is one strength of the cross-sectional design?

• A. It provides evidence about individual trends.
• B. It cannot be threatened by cohort effects.
• C. It is not plagued with dropout or practice effects.
• D. It permits longitudinal comparisons. Answer: C Page Ref: 34 Skill Level: Understand Topic: Studying Development Difficulty Level: Moderate

Correct answer: C

Rationale: One strength of the cross-sectional design is that it is not plagued with dropout or practice effects. This is because cross-sectional studies assess different individuals at the same point in time, eliminating the risk of participants dropping out or improving due to repeated measures.

5. Like longitudinal research, cross-sectional studies can be threatened by __________.

• A. practice effects
• B. participant dropout
• C. sequential timing
• D. cohort effects

Correct answer: D

Rationale: Cross-sectional studies can be threatened by cohort effects because different age groups may have experienced different historical or social contexts, influencing the results. This disparity can lead to invalid comparisons between age groups, confounding the study's findings. Option A, practice effects, refer to changes in participants' behavior due to repeated testing, not a specific threat to cross-sectional studies. Participant dropout (Option B) is a threat related to attrition in longitudinal studies, not cross-sectional studies. Sequential timing (Option C) does not pose a threat to cross-sectional studies; instead, it refers to the order of tasks in a study design.
