in mammals including humans the sense of smell

ATI RN

Human Growth and Development Final Exam

1. 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.

2. Self-reports __________.

A. use a flexible, conversational style to probe for the participant's point of view
B. describe the entire stream of behavior—everything said and done over a certain time period
C. range from relatively unstructured interviews to highly structured interviews, questionnaires, and tests
D. bring together a wide range of information on one person, including interviews, observations, and test scores

Correct answer: C

Rationale: Self-reports can range from relatively unstructured interviews to highly structured interviews, questionnaires, and tests. This variety allows researchers to collect information from participants in different ways, depending on the research goals and the type of information being sought. Choices A, B, and D are incorrect because they do not accurately describe the range and flexibility of self-reports as outlined in the field of research methodology.

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

A. fluid
B. crystallized
C. emotional
D. cultural

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. Shamona, a pregnant mother in Flint, Michigan, is concerned about the drinking water, which shows high levels of lead. Shamona should know that high levels of prenatal lead exposure are related to __________.

A. facial abnormalities and heart defects
B. defects of the genitals and urinary tract
C. low birth weight and brain damage
D. a variety of childhood cancers

Correct answer: C

Rationale: High levels of prenatal lead exposure are related to low birth weight and brain damage. Lead exposure during pregnancy can have harmful effects on the developing fetus, leading to complications such as decreased birth weight and potential long-term brain damage. Choices A, B, and D are incorrect because they do not directly correlate with the known effects of prenatal lead exposure. While lead exposure can indeed cause a variety of health issues, such as heart defects and urinary tract problems, the primary concerns related to prenatal exposure are low birth weight and brain damage.

5. Development is best understood as __________.

A. genetically determined
B. environmentally influenced
C. an unsolvable puzzle
D. a series of complex exchanges between nature and nurture

Correct answer: D

Rationale: The correct answer is D. Development is best understood as a series of complex exchanges between nature (genetic factors) and nurture (environmental influences). This perspective emphasizes the interaction and interplay between genetic predispositions and environmental experiences in shaping an individual's development. Choices A and B are too extreme as they suggest that development is solely determined by genetics or solely influenced by the environment, which is not the case. Choice C is incorrect as development is not viewed as an unsolvable puzzle but rather as a dynamic process influenced by multiple factors.
