Growth and Development Exam

1. The yolk sac __________.

Correct answer: C

Rationale: The yolk sac is an extraembryonic membrane that plays a significant role in the early development of the embryo. One of its functions is to produce blood cells until the organs are mature enough to take over this function. This process occurs during the early stages of prenatal development to support the growing embryo before it can sustain itself independently.

2. Dr. Torrez believes that how conflicts between biological drives and social expectations are resolved determines the person's ability to learn, to get along with others, and to cope with anxiety. Dr. Torrez accepts the __________.

Correct answer: A

Rationale: Dr. Torrez's belief about conflicts between biological drives and social expectations influencing a person's ability to learn, get along with others, and cope with anxiety aligns with the psychoanalytic perspective. This perspective, developed by Sigmund Freud, focuses on the unconscious mind, early childhood experiences, and the resolution of inner conflicts as important factors in shaping personality and behavior. The other choices are incorrect because psychosocial theory, cognitive-developmental theory, and social learning theory do not specifically focus on conflicts between biological drives and social expectations as central to understanding human behavior and development.

3. According to operant conditioning theory, __________.

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.

4. The __________ reflex helps a newborn find the nipple.

Correct answer: A

Rationale: The rooting reflex is the correct answer. This reflex helps a newborn baby find the nipple by turning their head and opening their mouth when their cheek is stroked or touched. This is crucial for the baby to locate and latch onto the mother's breast for feeding. The rooting reflex typically disappears around 4 months of age.

5. __________ love is strong at the beginning of a relationship.

Correct answer: C

Rationale: Passionate love is characterized by intense emotions and physical attraction, which are common in the early stages of relationships. Compassionate love involves deep affection, but it develops over time based on mutual respect, trust, and intimacy. Affectionate love is warm and tender, but it may not necessarily have the intense emotions associated with passionate love. Companionate love is based on friendship, respect, and affection, but it may lack the intense emotions and physical attraction that characterize passionate love.
