Human Growth and Development Clep Practice Exam
1. A __________ is a means of building schemes in which an infant who has stumbled onto a new experience caused by his or her own motor activity tries to repeat the event again and again.
- A. sensorimotor reflex
- B. circular reaction
- C. mental representation
- D. goal-directed behavior
Correct answer: B
Rationale: A circular reaction is a process where an infant repeats a specific action to explore and learn about the environment through their own motor activity. This repetition helps the infant to understand the consequences of their actions and build cognitive schemes. Sensorimotor reflex (choice A) refers to automatic responses to stimuli, not a purposeful repetition of actions to learn. Mental representation (choice C) involves internal cognitive structures to represent objects or events in the mind, which is different from the repetitive behavior described in the question. Goal-directed behavior (choice D) is purposeful and intentional, unlike the repetitive nature of circular reactions in infants' learning process.
2. In a cross-sectional design, researchers study __________.
- A. the same group of participants repeatedly at different ages
- B. groups of participants differing in age at the same point in time
- C. groups of participants of the same age in different years
- D. participants of the same age at the same point in time
Correct answer: B
Rationale: In a cross-sectional design, researchers study groups of participants differing in age at the same point in time. This design allows researchers to compare different age groups simultaneously, providing valuable insight into age-related differences without the need to track the same group over time. Choice A is incorrect because it describes a longitudinal design where the same group is followed over time. Choice C is incorrect as it involves different groups of the same age studied at different times. Choice D is incorrect as it does not capture the essence of a cross-sectional design, which involves studying groups of different ages at the same point in time.
3. The term teratogen refers to __________.
- A. any environmental agent that causes damage during the prenatal period
- B. a limited time span during which a part of the body is biologically prepared to develop rapidly
- C. a rapid period of prenatal neurological development
- D. a synthetic hormone used to prevent miscarriage
Correct answer: A
Rationale: The correct answer is A: 'any environmental agent that causes damage during the prenatal period.' A teratogen is any substance or factor that can cause harm to the developing fetus during pregnancy. Choice B is incorrect because it describes a critical period, not a teratogen. Choice C is incorrect as it refers to a specific period of development, not a teratogen. Choice D is incorrect because it describes a synthetic hormone, not a teratogen.
4. When trying to soothe a crying baby, what technique do Western parents typically attempt first?
- A. Massaging the baby's body
- B. Offering a pacifier and a receiving blanket
- C. Playing recorded womb sounds or sounds of nature
- D. Lifting the baby to the shoulder and rocking or walking
Correct answer: D
Rationale: When Western parents aim to soothe a crying baby, the technique they usually try first is lifting the baby to the shoulder and rocking or walking. This method is effective because the motion and closeness provided by rocking or walking can help calm the baby and offer comfort. Choice A is incorrect as massaging the baby's body is not typically the first technique used. Choice B is incorrect as offering a pacifier and a receiving blanket may be tried after lifting the baby to the shoulder. Choice C is also incorrect as playing recorded sounds is usually not the initial technique attempted.
5. The effects of stress on the developing organism can be greatly reduced if the expectant mother __________.
- A. has access to social support during stressful periods
- B. takes a low dose of anti-anxiety medication
- C. takes a folic acid supplement early in pregnancy
- D. is placed on bed rest during the last trimester
Correct answer: A
Rationale: Having access to social support during stressful periods can greatly reduce the effects of stress on the developing organism. Social support can provide emotional comfort, practical assistance, and a sense of belonging, which can help the expectant mother cope with stress more effectively. This support system can also help mitigate the negative impact of stress on the developing baby during pregnancy. Choices B, C, and D are incorrect because while folic acid is important for prenatal health, it does not directly address the effects of stress. Taking anti-anxiety medication should be done under medical supervision and as a last resort due to potential risks to the developing baby. Bed rest during the last trimester is not a solution to reduce the effects of stress and may not address the underlying causes of stress.
