Human Growth and Development Final Exam Quizlet
1. Children in middle childhood are in Piaget's _______ stage, which extends from about 7 to 11 years.
- A. sensorimotor
- B. preoperational
- C. concrete operational
- D. formal operational
Correct answer: C
Rationale: The correct answer is C: concrete operational. During the concrete operational stage, children start to engage in logical thinking about concrete events. This stage typically occurs between the ages of 7 to 11 years. Choices A, B, and D are incorrect. The sensorimotor stage (choice A) is the first stage in Piaget's theory, occurring from birth to about 2 years old. The preoperational stage (choice B) follows the sensorimotor stage and occurs roughly from ages 2 to 7 years. The formal operational stage (choice D) is the final stage in Piaget's theory, where abstract thinking and hypothetical reasoning develop, usually beginning around age 11.
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. An experimental design __________.
- A. allows researchers to gather information in natural life circumstances without altering the participants' experiences
- B. looks at relationships between participants' characteristics and their behavior or development
- C. permits inferences about cause and effect because researchers evenhandedly assign people to treatment conditions
- D. has one major limitation: researchers cannot infer cause and effect
Correct answer: C
Rationale: An experimental design permits inferences about cause and effect because researchers evenhandedly assign people to treatment conditions. This means that researchers can manipulate certain variables and observe the effects on participants, allowing them to determine causation between variables. This is a key strength of experimental research designs. Choices A, B, and D are incorrect because they do not accurately describe the primary purpose or strength of experimental designs. Experimental designs do not focus on gathering information in natural life circumstances (A), looking at relationships between characteristics and behavior (B), or have the limitation of not being able to infer cause and effect (D).
4. To avoid exposure to toxoplasmosis, Kaye should ask other family members to __________.
- A. stop smoking
- B. pick up after the dog
- C. change the litter box
- D. feed the fish
Correct answer: C
Rationale: To avoid exposure to toxoplasmosis, Kaye should ask other family members to change the litter box. Toxoplasmosis is a parasitic infection that can be transmitted through cat feces, so it is important for pregnant women to avoid handling cat litter to reduce the risk of infection. Choices A, B, and D are incorrect because they are not directly related to preventing toxoplasmosis. Smoking cessation is important for overall health but not specifically to prevent toxoplasmosis. Picking up after the dog and feeding the fish are not relevant to preventing toxoplasmosis, as the infection is primarily associated with cat feces.
5. 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.
