what do genes consist of

ATI RN

Psychology 101 Exam 3 Test

1. What are genes made of?

A. Trisomes
B. Chromosomes
C. DNA
D. Proteins

Correct answer: C

Rationale: Genes are made of DNA, which is the genetic material that carries the instructions for the development, functioning, growth, and reproduction of organisms. While chromosomes contain genes, they are not what genes themselves are made of. Proteins are involved in gene expression and regulation, but they are not the primary material genes consist of. Trisomes is an incorrect term in this context and does not relate to the composition of genes.

2. Strict behaviorists would be most sympathetic to which one of the following statements?

A. Human behavior is primarily caused by inherited factors.
B. Human behavior is primarily caused by environmental factors.
C. Human behavior is primarily caused by equal contributions of inherited and environmental factors.
D. No one really knows the primary causes for human behavior.

Correct answer: B

Rationale: Strict behaviorists, who adhere to behaviorism, believe that human behavior is primarily influenced by environmental factors. This perspective asserts that individuals' actions and responses are shaped by their interactions with the environment, learning experiences, and external stimuli. Choice A is incorrect because strict behaviorists do not focus on inherited factors but on how behavior is learned and shaped through environmental influences. Choice C is also incorrect as behaviorists do not believe in equal contributions of inherited and environmental factors; they emphasize environmental determinants. Choice D is incorrect as behaviorists have a clear stance that behavior is influenced by environmental stimuli and learning experiences.

3. Who took the position that organisms tend to repeat responses that lead to positive outcomes and tend not to repeat responses that lead to neutral or negative outcomes?

A. Sigmund Freud
B. B.F. Skinner
C. Carl Rogers
D. Abraham Maslow

Correct answer: B

Rationale: The correct answer is B.F. Skinner. Skinner proposed the theory of operant conditioning, where behavior is shaped by its consequences. Positive outcomes increase the likelihood of a behavior being repeated, while neutral or negative outcomes decrease it. Sigmund Freud (choice A) is known for his psychoanalytic theory, Carl Rogers (choice C) for person-centered therapy, and Abraham Maslow (choice D) for the hierarchy of needs.

4. In a breech presentation, how is the infant positioned for delivery?

A. Is too large to be delivered vaginally.
B. Is delivered feet or bottom first.
C. Is delivered head first.
D. Appears face down.

Correct answer: B

Rationale: In a breech presentation, the infant is positioned to be delivered feet or bottom first. This is because the baby's pelvis or feet enter the birth canal before the head. Therefore, choice B is correct. Choices A, C, and D are incorrect because a breech presentation specifically refers to the baby being positioned feet or bottom first, not head first, face down, or being too large for vaginal delivery.

5. A group of psychologists is conducting research to determine whether people eat more when they are in the presence of environmental stimuli that increase anxiety, such as loud noises or flashing lights. These scientists most likely follow?

A. The behavioral perspective.
B. The psychodynamic perspective.
C. The humanistic perspective.
D. The functionalist perspective.

Correct answer: A

Rationale: The correct answer is A, the behavioral perspective. This perspective focuses on how environmental stimuli influence behavior, making it suitable for studying how anxiety-inducing stimuli affect eating behavior. The psychodynamic perspective (choice B) would focus more on unconscious processes and early life experiences. The humanistic perspective (choice C) emphasizes personal growth and self-actualization. The functionalist perspective (choice D) is more related to the study of the purpose of behavior and mental processes in adapting to the environment.
