Human Growth and Development Exam 1
1. What is the goal of applied behavior analysis?
- A. outline changes in temperament over the lifespan
- B. eliminate undesirable behaviors and increase desirable responses
- C. examine how we think about ourselves and other people
- D. synthesize information from various sources into a detailed picture of a person's personality
Correct answer: B
Rationale: The correct answer is B: "eliminate undesirable behaviors and increase desirable responses." Applied behavior analysis aims to modify behavior by focusing on eliminating unwanted behaviors and reinforcing desirable ones. It does not primarily deal with changes in temperament (choice A), self-perception (choice C), or personality traits (choice D). The approach involves techniques such as reinforcement to target specific behaviors, rather than broader cognitive processes or personality characteristics.
2. To study the impact of biological aging on motor skills, researchers focus on __________.
- A. sedentary adults
- B. competitive athletes
- C. men in their mid- to late thirties
- D. women in their childbearing years
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.
3. Swaddling newborns __________.
- A. increases crying
- B. hinders early motor development
- C. promotes an insecure attachment relationship
- D. restricts movement and increases warmth
Correct answer: D
Rationale: Swaddling newborns restricts their movement by wrapping them snugly in a blanket, which helps to mimic the feeling of security they had in the womb. It also helps to maintain their warmth and can promote better sleep patterns. Choices A, B, and C are incorrect because swaddling does not increase crying, hinder early motor development, or promote an insecure attachment relationship. Instead, it provides comfort, warmth, and a sense of security for newborns.
4. Recent evidence suggests that paternal alcohol use around the time of conception __________.
- A. can alter gene expression
- B. can cause fetal alcohol syndrome
- C. is linked to blood vessel abnormalities
- D. has no negative effect on the developing organism
Correct answer: A
Rationale: Recent evidence suggests that paternal alcohol use around the time of conception can alter gene expression. This means that paternal alcohol consumption can potentially impact the genes and genetic materials passed on to offspring, affecting their development and health. Choice B is incorrect because fetal alcohol syndrome is typically associated with maternal alcohol consumption during pregnancy, not paternal alcohol use around conception. Choice C is incorrect as there is no direct link between paternal alcohol use and blood vessel abnormalities. Choice D is incorrect as paternal alcohol use can indeed have negative effects on the developing organism, particularly through altering gene expression.
5. What is the function of the amniotic fluid?
- A. Delivers food and oxygen to the developing organism
- B. Helps keep the temperature of the prenatal world constant
- C. Delivers nutrients and removes waste products
- D. Produces blood cells until the organs are mature enough to take over this function
Correct answer: B
Rationale: The correct answer is B: 'Helps keep the temperature of the prenatal world constant.' Amniotic fluid helps maintain a stable and warm environment for the developing organism, assisting in regulating the temperature. This fluid also acts as a cushion, protecting the fetus from physical harm. Choices A, C, and D are incorrect because while amniotic fluid provides protection and support to the developing organism, it does not directly deliver food, oxygen, nutrients, or remove waste products, nor does it produce blood cells as the organs eventually take over this function.
