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. Taking tests and answering questionnaires are examples of __________.

A. research designs
B. theories
C. hypotheses
D. research methods

Correct answer: D

Rationale: Taking tests and answering questionnaires are examples of research methods. Research methods refer to the specific approaches used in conducting research, such as collecting data, analyzing information, and drawing conclusions. In this case, tests and questionnaires are tools used to gather information and data for research purposes, making them examples of research methods. Choices A, B, and C are incorrect because research designs refer to the overall structure and plan of a study, theories are explanations developed through research and observation, and hypotheses are specific predictions or statements that can be tested through research.

3. How does physical activity impact mental health?

A. Reduces anxiety and depression
B. Improves mood, but decreases alertness
C. Decreases mood, alertness, and energy
D. Decreases neural activity in the cerebral cortex

Correct answer: A

Rationale: Physical activity is known to have a positive impact on mental health by reducing symptoms of anxiety and depression. Choice B is incorrect because physical activity generally improves both mood and alertness. Choice C is incorrect as physical activity tends to increase mood, alertness, and energy levels. Choice D is incorrect as physical activity actually increases neural activity in the cerebral cortex, which is associated with improved cognitive function and mental well-being.

4. By the end of Greta's first month of pregnancy, her embryo __________.

A. can sense its world
B. is about ¼ inch long
C. can suck its thumb
D. can curl its toes

Correct answer: B

Rationale: By the end of Greta's first month of pregnancy, her embryo is about ¼ inch long. During the first month of pregnancy, the embryo is in the very early stages of development, and its size is typically around ¼ inch as it continues to grow and develop in the uterus. Choices A, C, and D are incorrect because sensory abilities like sensing the world, sucking thumb, and curling toes develop later in the pregnancy as the embryo progresses through different stages of development.

5. Evolutionary developmental psychology __________.

A. focuses on how the structures of the mind develop to better fit with, or represent, the external world
B. seeks to understand the adaptive value of species-wide competencies as those competencies change with age
C. views the human mind as a symbol-manipulating system through which information flows
D. brings together researchers from many fields to study changes in the brain and behavior patterns

Correct answer: B

Rationale: Evolutionary developmental psychology seeks to understand the adaptive value of species-wide competencies as those competencies change with age. This field focuses on how psychological traits and behaviors have evolved to enhance survival and reproduction over time. It emphasizes the interaction between evolutionary principles and developmental processes to provide insights into human behavior and cognition. Choices A, C, and D are incorrect because they do not accurately describe the primary focus of evolutionary developmental psychology. Choice A is more aligned with cognitive psychology, choice C relates to cognitive science, and choice D could pertain to multidisciplinary approaches but not specifically to evolutionary developmental psychology.
