Exam 4 Psychology

1. Which of the following statements is least likely to be made by a humanist?

A. Humans are unique.
B. The behavior of humans tends to be influenced by environmental circumstances.
C. Humans have a basic need to fulfill their potentials.
D. Research on animals has little relevance to understanding human behavior.

Correct answer: B

Rationale: The corrected question assesses the least likely statement made by a humanist. Choice B, 'The behavior of humans tends to be influenced by environmental circumstances,' is least likely to be made by a humanist. Humanists believe that human behavior is not simply dictated by environmental circumstances but is influenced by a combination of factors, including personal experiences, emotions, and conscious decisions. Choices A, C, and D are more aligned with humanist perspectives. Choice A acknowledges the uniqueness of humans, which is a common theme in humanistic psychology. Choice C reflects the humanistic belief that individuals strive to reach their full potential and self-actualization. Choice D contrasts with humanist views as humanists often consider research on animals to be relevant in understanding human behavior due to shared basic psychological processes.

2. Neural plasticity is ________.

A. the process by which neurotransmitters are broken down in the brain.
B. the flexibility of the brain—existing neural circuits can change or new ones can be made.
C. strong evidence of brain damage, leading to the development of a mental disorder.
D. the best indicator of temperament and its effect on the personality development of a child.

Correct answer: B

Rationale: Neural plasticity refers to the brain's flexibility to change existing neural circuits or create new ones. Choice A is incorrect as it describes neurotransmitter breakdown, not neural plasticity. Choice C is incorrect because neural plasticity does not necessarily indicate brain damage leading to mental disorders. Choice D is incorrect because neural plasticity is not specifically related to temperament or personality development in children.

3. Why is it particularly useful to study identical twins who were raised in different environments?

A. Differences in brain function can be easily identified.
B. Concordance rates tend to be higher.
C. It is possible that the genetics of twins who have been separated have changed in ways to explain any differences found.
D. It is possible that high concordance rates between identical twins reared together are due to their being treated more similarly than nonidentical twins.

Correct answer: D

Rationale: Studying identical twins raised in different environments allows researchers to understand the impact of genetics versus environmental factors on traits. Choice A is incorrect because differences in brain function can be influenced by a variety of factors and not solely by environmental differences. Choice B is incorrect as concordance rates tend to be higher in identical twins reared together due to shared genetics and environment. Choice C is incorrect because genetics do not change due to being raised in different environments.

4. Normal human cells have ________

A. twenty-two chromosome pairs and one pair of sex chromosomes.
B. twenty-one trisomy chromosome pairs, one autosomal pair, and one pair of sex chromosomes.
C. twenty-one chromosome pairs and two trisomy chromosome pairs.
D. twenty-three chromosome pairs.

Correct answer: A

Rationale: Normal human cells have twenty-two chromosome pairs and one pair of sex chromosomes. This is the correct answer as it accurately describes the typical chromosome count in human cells. Choice B is incorrect because it mentions 'twenty-one trisomy chromosome pairs,' which is not characteristic of normal cells. Choice C is incorrect as it suggests having 'two trisomy chromosome pairs,' which is abnormal. Choice D is incorrect as it states 'twenty-three chromosome pairs,' which is not the standard count in normal human cells.

5. What is a person's total genetic endowment?

A. Phenotype
B. Genotype
C. Chromosomes
D. DNA

Correct answer: B

Rationale: The correct answer is B: Genotype. A genotype refers to a person's total genetic endowment, representing the specific genetic makeup inherited from their parents. This includes all the genes and genetic information contained in an individual's DNA. Choices A, C, and D are incorrect because: A) Phenotype refers to the observable characteristics resulting from the interaction of genetics and the environment; C) Chromosomes are physical structures that contain genes, not the total genetic endowment itself; D) DNA carries genetic information but is just one component of an individual's total genetic endowment.
