Growth and Development Exam

1. By the twelfth week of pregnancy, __________.

Correct answer: A

Rationale: By the twelfth week of pregnancy, the sex of the fetus can be detected with ultrasound. Ultrasound technology allows for visualization of the developing fetus and identification of physical characteristics, such as sex, during prenatal appointments.

2. Women who __________ tend to reach menopause earlier.

Correct answer: C

Rationale: The correct answer is C: 'have not borne children.' Women who have not borne children may experience menopause earlier due to lower levels of certain reproductive hormones. Having two or more children (choice A) is not typically associated with reaching menopause earlier. Smoking (choice B) is known to have negative effects on menopause but does not necessarily cause it to happen earlier. Borne twins (choice D) is a specific scenario and not a general factor influencing the timing of menopause.

3. To study the impact of biological aging on motor skills, researchers focus on __________.

Correct answer: B

Rationale: The correct answer is B: competitive athletes. Competitive athletes are often studied by researchers to investigate the impact of biological aging on motor skills because their performance is closely linked to physical abilities. Sedentary adults (choice A) may not provide a clear understanding of the relationship between biological aging and motor skills as they may not engage in consistent physical activity. Men in their mid- to late thirties (choice C) and women in their childbearing years (choice D) may not represent a group where motor skills are as finely tuned and critical to performance as in competitive athletes.

4. Today, research that combines an experimental strategy with __________ approach is becoming increasingly common.

Correct answer: C

Rationale: The blank in the statement refers to an approach that can be used in combination with an experimental strategy. Longitudinal and cross-sectional approaches are two common research methods in developmental psychology. Longitudinal studies involve following the same group of individuals over an extended period, while cross-sectional studies compare different groups of individuals of different ages at the same time. By combining an experimental strategy with either a longitudinal or a cross-sectional approach, researchers can gain a deeper understanding of developmental processes and changes over time. Choices A, B, and D are incorrect because correlational and sequential are not the most relevant approaches when studying developmental changes over time in research.

5. What reflex protects an infant from strong stimulation?

Correct answer: B

Rationale: The correct answer is B: eye-blink. The eye-blink reflex is the one that protects an infant from strong stimulation by causing them to quickly shut their eyes in response to sudden bright light or a loud noise. This reflex helps to safeguard the infant's sensitive eyes from potential harm. The Moro reflex (choice A) is the startle reflex, the sucking reflex (choice C) helps with feeding, and the palmar grasp reflex (choice D) is when the infant's fingers close around an object placed in their hand; none of these reflexes specifically protect the infant from strong stimulation.
