Human Growth and Development Clep Practice Exam
1. How does physical activity impact mental health?
- A. Reduces anxiety and depression
- B. Improves mood, but decreases alertness
- C. Decreases mood, alertness, and energy
- D. Decreases neural activity in the cerebral cortex
Correct answer: A
Rationale: Physical activity is known to have a positive impact on mental health by reducing symptoms of anxiety and depression. Choice B is incorrect because physical activity generally improves both mood and alertness. Choice C is incorrect as physical activity tends to increase mood, alertness, and energy levels. Choice D is incorrect as physical activity actually increases neural activity in the cerebral cortex, which is associated with improved cognitive function and mental well-being.
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. Spatial skills __________.
- A. increase exponentially in early childhood
- B. support children's improved executive function
- C. develop gradually over childhood and adolescence
- D. are typically housed in the left hemisphere
Correct answer: C
Rationale: Spatial skills develop gradually over childhood and adolescence, reflecting the increasing complexity of these abilities. Choice A is incorrect because spatial skills do not increase exponentially in early childhood but rather develop steadily. Choice B is incorrect as spatial skills are not directly linked to executive function. Choice D is incorrect because spatial skills are not typically housed in a specific hemisphere but involve a network of brain regions.
4. Which statement about epidural analgesia is true?
- A. It numbs the entire lower half of the body.
- B. It limits pain reduction to the pelvic region.
- C. It strengthens uterine contractions.
- D. It shortens the length of labor.
Correct answer: B
Rationale: The correct statement about epidural analgesia is that it limits pain reduction to the pelvic region by blocking nerve signals from that specific area, providing pain relief during labor and delivery. Choice A is incorrect because epidural analgesia does not numb the entire lower half of the body. Choice C is incorrect because epidural analgesia does not strengthen uterine contractions; in fact, it may sometimes weaken them. Choice D is incorrect because epidural analgesia does not shorten the length of labor; it can sometimes prolong labor.
5. Adults often provide indirect feedback about grammar by using __________, which restructures inaccurate speech into correct form.
- A. fast-mapping
- B. an expansion
- C. overregularization
- D. a recast
Correct answer: D
Rationale: The correct answer is 'a recast.' A recast occurs when an adult rephrases a child's incorrect speech into the accurate form, aiding in the learning of proper grammar. Choice A, 'fast-mapping,' refers to the ability to learn new words quickly; choice B, 'an expansion,' typically involves adding more information to a child's speech; choice C, 'overregularization,' is an error children make when they apply grammatical rules too broadly.
