Human Growth and Development Final Exam

1. When the blastocyst burrows deep into the uterine lining, __________.

Correct answer: A

Rationale: When the blastocyst burrows deep into the uterine lining, this process is known as implantation. Implantation is a crucial step in the early stages of pregnancy where the blastocyst attaches to the uterine wall in order to receive nourishment and continue developing. Choice B is incorrect because implantation is a necessary step for pregnancy to occur. Choice C is incorrect as implantation marks the beginning of further growth and development. Choice D is incorrect as the duplication of cells occurs during earlier stages of development, not during implantation.

2. By age 2, children __________.

Correct answer: C

Rationale: By age 2, children are capable of adjusting their speech to fit the age of their listeners, showing early social cognition. Choice A is incorrect because taking turns in face-to-face interaction typically develops later in childhood. Choice B is incorrect as the ability to infer a speaker's indirectly expressed intention is a more advanced skill not typically seen at age 2. Choice D is also incorrect as children at age 2 are not developmentally ready to adjust their speech based on the social status of their listeners.

3. The more a mental ability depends on __________ intelligence, the earlier it starts to decline.

Correct answer: A

Rationale: The correct answer is A: fluid. Fluid intelligence, which involves problem-solving and reasoning, tends to decline earlier than crystallized intelligence. Crystallized intelligence, on the other hand, involves knowledge and skills acquired over time and is more stable with age. Emotional intelligence and cultural intelligence are not directly related to the decline of mental abilities mentioned in the question, making them incorrect choices.

4. Dr. George predicted that positive reinforcement would increase prosocial behavior in preschoolers. Dr. George's prediction is an example of a __________.

Correct answer: C

Rationale: Dr. George's prediction that positive reinforcement would increase prosocial behavior in preschoolers is an example of a hypothesis. A hypothesis is a specific, testable prediction about the relationship between variables based on existing knowledge or theories. In this case, Dr. George is making a prediction about the effect of positive reinforcement on prosocial behavior, which can be tested through research. Choice A, 'theory,' is incorrect because a theory is a broader explanation that integrates a range of findings and observations. Choice B, 'research question,' is incorrect as it refers to an inquiry that asks about the relationship between variables but lacks the specificity and testability of a hypothesis. Choice D, 'research design,' is incorrect as it pertains to the overall strategy or plan for conducting a research study, not the specific prediction Dr. George made.

5. Dr. Singh believes that a basic psychosocial conflict, which is resolved along a continuum from positive to negative, determines healthy or maladaptive outcomes at each stage of development. Dr. Singh's beliefs are aligned with those of which theorist?

Correct answer: C

Rationale: Dr. Singh's beliefs align with Erik Erikson's psychosocial theory of development. Erikson proposed that individuals go through a series of psychosocial stages, with each stage characterized by a basic conflict that must be resolved to achieve healthy development. This conflict is resolved along a continuum from positive to negative outcomes. Choice A, G. Stanley Hall, is incorrect as his work focused on adolescence and evolutionary psychology. Choice B, Sigmund Freud, is incorrect as his psychoanalytic theory is more focused on the unconscious mind and psychosexual stages. Choice D, B. F. Skinner, is incorrect as he is associated with behaviorism and operant conditioning, which is different from Erikson's psychosocial theory.
