Human Growth and Development Exam 1
1. According to operant conditioning theory, __________.
- A. the frequency of a behavior can be increased through punishment, such as disapproval
- B. normal development must be understood in relation to each culture's life situation
- C. the id develops as parents insist that children conform to the values of society
- D. the frequency of a behavior can be increased by following it with a wide variety of reinforcers
Correct answer: D
Rationale: According to operant conditioning theory, the frequency of a behavior can be increased by following it with a wide variety of reinforcers. In operant conditioning, behaviors are shaped through reinforcement, which can be positive (rewarding) or negative (removal of something unpleasant). By providing reinforcement following a behavior, the likelihood of that behavior occurring again in the future is increased. This supports the notion that the frequency of a behavior can be increased by using reinforcers in operant conditioning. Choices A, B, and C are incorrect because operant conditioning focuses on the relationship between behavior and its consequences through reinforcement (positive or negative) to increase the likelihood of the behavior recurring, rather than punishment, cultural influences, or the development of the id based on societal values.
2. In the information-processing system, where does information first enter?
- A. central executive
- B. short-term memory store
- C. sensory register
- D. long-term memory store
Correct answer: C
Rationale: In the information-processing system, information first enters the sensory register. This is where sensory information from the environment is briefly stored before being processed further. The central executive is responsible for coordinating cognitive processes, the short-term memory store holds information temporarily for immediate tasks, and the long-term memory store stores information for long periods, but the sensory register is the initial entry point for incoming information.
3. Which statement about prenatal marijuana exposure is true?
- A. It is linked to impulsivity and overactivity.
- B. Lasting consequences are well-established.
- C. Studies show no negative effects of exposure.
- D. It is linked to an array of physical malformations.
Correct answer: A
Rationale: The correct answer is A: 'It is linked to impulsivity and overactivity.' Prenatal marijuana exposure has been associated with impulsivity and overactivity in children based on research findings. However, lasting consequences of prenatal marijuana exposure are not as well-established compared to other teratogens. Choice B is incorrect because lasting consequences are not firmly established. Choice C is incorrect because studies have shown negative effects of prenatal marijuana exposure. Choice D is incorrect as prenatal marijuana exposure is not primarily linked to physical malformations.
4. Among preschoolers, __________ contributes to gains in emotional self-regulation.
- A. permissive child rearing
- B. authoritarian child rearing
- C. language
- D. family size
Correct answer: C
Rationale: Corrected Rationale: Language development plays a crucial role in emotional self-regulation in preschoolers. It enables children to express and manage their emotions effectively. Choices A and B, permissive and authoritarian child rearing styles, focus more on the parenting approach rather than the child's intrinsic development. Family size, as mentioned in choice D, does not directly contribute to gains in emotional self-regulation.
5. What is the function of the corpus luteum?
- A. is where fertilization usually takes place
- B. secretes hormones that prepare the lining of the uterus to receive a fertilized ovum
- C. is one of two long, thin structures that lead to the hollow, softly lined uterus
- D. is one of two walnut-sized organs located deep inside a woman's abdomen
Correct answer: B
Rationale: The correct answer is B. The corpus luteum is a temporary endocrine structure in the ovary that forms after ovulation. It secretes hormones, particularly progesterone, which help prepare the uterine lining for possible implantation of a fertilized ovum. This process is crucial for maintaining a potential pregnancy. Choices A, C, and D are incorrect. Choice A is inaccurate as fertilization typically occurs in the fallopian tubes. Choice C describes the fallopian tubes, not the corpus luteum. Choice D refers to the ovaries, not specifically the corpus luteum.
