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. When Baby Ian is held horizontally on his back, he sometimes makes an “embracing” motion by arching his back, extending his legs, throwing his arms outward, and then bringing his arms in toward his body. Ian is demonstrating the __________.

A. palmar grasp
B. Moro reflex
C. tonic neck reflex
D. Babinski reflex

Correct answer: B

Rationale: Baby Ian is demonstrating the Moro reflex. The Moro reflex is a normal newborn reflex that occurs when a baby feels like they are falling or losing support. It is characterized by arching the back, extending the legs, throwing the arms outward, and then bringing the arms in toward the body. This reflex is a primitive survival instinct that typically disappears around 6 months of age. Choice A, palmar grasp, involves the baby's fingers closing around an object when it touches their palm. Choice C, tonic neck reflex, involves the baby assuming a fencing position when their head is turned to one side. Choice D, Babinski reflex, is characterized by the fanning out and curling of the baby's toes when the sole of the foot is stroked.

3. __________ doubles the risk of SIDS.

A. Failure to tightly swaddle an infant during sleep
B. Use of a pacifier or a security blanket
C. Placing an infant to sleep on his back
D. Cigarette smoking by a caregiver Answer: D Page Ref: 106 Box: BIOLOGY AND ENVIRONMENT: The Mysterious Tragedy of Sudden Infant Death Syndrome Skill Level: Understand Topic: The Newborn BabyÃ¢â‚¬â„¢s Capacities Difficulty Level: Moderate

Correct answer: D

Rationale: Cigarette smoking by a caregiver doubles the risk of SIDS. Secondhand smoke exposure can increase the likelihood of SIDS due to the toxins and chemicals present in cigarette smoke. It is important to have a smoke-free environment for infants to reduce the risk of SIDS.

4. Dr. Dias's research shows that the death of a spouse in old age is correlated with a decline in the surviving partner's physical health. Which conclusion is supported by this study?

A. The death of a spouse causes a decline in the surviving partner's physical health.
B. The death of a spouse is related to a decline in the surviving partner's physical health.
C. A decline in a surviving partner's physical health can cause the death of a spouse.
D. A third variable, such as memory loss, causes a surviving partner's decline in physical health following the death of a spouse.

Correct answer: B

Rationale: Dr. Dias's research findings indicate a correlation between the death of a spouse and a decline in the surviving partner's physical health. This correlation suggests a relationship between the two variables, but it does not necessarily imply a direct cause-and-effect relationship. Therefore, the correct conclusion supported by this study is option B - 'The death of a spouse is related to a decline in the surviving partner's physical health.' Option A is too direct in its causation claim, which is not proven by correlation alone. Option C reverses the cause and effect relationship suggested by the research. Option D introduces an unrelated third variable, which is not supported by the study's findings.

5. 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.
