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. In mammals, including humans, the sense of smell __________.

A. does not become adultlike for several years
B. helps mothers and babies identify each other
C. is the least developed sense at birth
D. takes about four months to become adultlike

Correct answer: B

Rationale: The sense of smell in mammals, including humans, plays a crucial role in helping mothers and babies identify each other. This is important for initiating bonding and caregiving behaviors. Choice A is incorrect because the sense of smell is functional at birth and not entirely underdeveloped for several years. Choice C is incorrect as the sense of smell is actually well-developed at birth. Choice D is incorrect because the sense of smell is functional from birth and does not take several months to become adultlike.

3. During the second month of pregnancy, __________.

A. the umbilical cord first appears as a primitive body stalk
B. touch sensitivity extends to most of the body
C. the heart develops separate chambers
D. the heartbeat can be heard through a stethoscope

Correct answer: C

Rationale: During the second month of pregnancy, the heart of the developing fetus begins to develop separate chambers, forming the structure necessary for a fully functioning heart. This is a significant milestone in the prenatal development process. Choices A, B, and D are incorrect because the appearance of the umbilical cord as a primitive body stalk typically occurs around week 5-6, touch sensitivity extending to most of the body is more characteristic of the end of the second trimester, and the heartbeat is usually detectable through a stethoscope around the 18th to 20th week of pregnancy, not during the second month.

4. According to Erikson, the danger in middle childhood is __________, reflected in the pessimism of children who lack confidence in their ability to do things well.

A. shame
B. mistrust
C. inferiority
D. despair

Correct answer: C

Rationale: According to Erikson's psychosocial theory, the danger in middle childhood is 'inferiority.' During this stage, children may develop a sense of inadequacy and inferiority if they are unable to master the social and academic tasks expected of them. This feeling of inferiority can lead to low self-esteem and pessimism about their abilities. Choice A, 'shame,' is more closely associated with Erikson's stage of autonomy vs. shame and doubt in early childhood. Choice B, 'mistrust,' is linked to Erikson's stage of trust vs. mistrust in infancy. Choice D, 'despair,' is related to Erikson's stage of integrity vs. despair in late adulthood.

5. A 20-week-old fetus can __________.

A. be stimulated as well as irritated by sounds
B. survive, if born early
C. breathe without oxygen assistance, if born early
D. control its own body temperature Answer: A Page Ref: 80 Skill Level: Understand Topic: Prenatal Development Difficulty Level: Moderate

Correct answer: A

Rationale: A 20-week-old fetus is able to be stimulated as well as irritated by sounds because by this stage of prenatal development, the fetus's auditory system is already well-developed. It can respond to external sounds and may even startle or move in reaction to loud noises.
