1. 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.

2. During prenatal development, the ectoderm becomes the __________.

A. muscles and skeleton
B. nervous system and skin
C. circulatory system and other internal organs
D. digestive system, lungs, urinary tract, and glands

Correct answer: B

Rationale: The correct answer is B: nervous system and skin. The nervous system, which includes the brain, spinal cord, and nerves, as well as the skin, develop from the ectoderm layer of cells during prenatal development. Choice A is incorrect because muscles and skeleton develop from mesoderm. Choice C is incorrect because the circulatory system and other internal organs develop from mesoderm and endoderm. Choice D is incorrect because the digestive system, lungs, urinary tract, and glands develop from endoderm.

3. An inadequate diet during pregnancy can __________.

A. lead to higher birth weight and greater brain weight
B. reduce the risk of pregnancy-induced maternal diabetes
C. distort the structure of the liver, kidney, and pancreas
D. lead to fewer physical discomforts in the final weeks Answer: C Page Ref: 88 Skill Level: Understand Topic: Prenatal Environmental Influences Difficulty Level: Moderate

Correct answer: C

Rationale: An inadequate diet during pregnancy can lead to the distortion of the structure of the liver, kidney, and pancreas in the developing fetus. Proper nutrition during pregnancy is crucial for the healthy development of these organs and essential for the overall well-being of the baby. A balanced diet supports optimal growth and development, while inadequate nutrition can have detrimental effects on the baby's organs and long-term health.

4. Which statement describes a strength of naturalistic observation?

A. It reflects the participants' everyday lives.
B. It permits comparisons of participants' responses.
C. Great depth and breadth of information can be obtained in a short time.
D. It grants each participant an equal opportunity to display the behavior of interest.

Correct answer: A

Rationale: Naturalistic observation reflects the participants' everyday lives because it involves observing individuals in their natural environments without any manipulation. This allows researchers to see how people behave in real-world settings and can provide valuable insights into their typical behavior patterns. Choice B is incorrect because naturalistic observation focuses on observing behavior in its natural setting rather than comparing responses between participants. Choice C is incorrect as naturalistic observation tends to provide rich, qualitative data rather than a large amount of information in a short time. Choice D is incorrect because in naturalistic observation, participants are observed as they naturally behave, which may not always lead to an equal opportunity for all participants to display the behavior of interest.

5. Low-level radiation, resulting from industrial leakage or medical X-rays, __________.

A. is harmful only when combined with other teratogens
B. can increase the risk of childhood cancer
C. rarely causes lasting damage
D. is safe during the last trimester

Correct answer: B

Rationale: Low-level radiation, whether from industrial leakage or medical X-rays, can increase the risk of childhood cancer by potentially damaging the developing fetus's cells. Even though the risk is relatively low, it is still a significant concern that should be acknowledged and monitored closely, especially during prenatal development. Choice A is incorrect as low-level radiation can still be harmful on its own without the need to be combined with other teratogens. Choice C is incorrect because low-level radiation exposure can indeed cause lasting damage, especially in the context of childhood cancer risk. Choice D is incorrect because low-level radiation exposure, even during the last trimester, can pose risks to the developing fetus and is not considered entirely safe.
