Exam 4 Psychology 101

Correct Answer: D

Rationale: The correct answer is D because in an experimental design, investigators manipulate variables to determine the effect of one on another. This process allows researchers to test causal hypotheses by manipulating one variable while keeping others constant. Choices A, B, and C are incorrect as they do not directly relate to manipulating variables in an experiment.

Correct Answer: D

Rationale: The correct answer is Dopamine. Dopamine was initially thought to be the primary cause of schizophrenia. This neurotransmitter hypothesis was based on the observation that drugs that increase dopamine activity can worsen symptoms of schizophrenia, while drugs that decrease dopamine activity can improve symptoms. Choices A, B, and C are incorrect because GABA, serotonin, and epinephrine were not the neurotransmitters initially believed to be the cause of schizophrenia.

Correct Answer: B

Rationale: The correct answer is B: Proximodistal pattern. Differences between monozygotic twins raised in the same environment are likely due to non-shared environmental influences, which lead to differences in interests, hobbies, and other individual characteristics. Choices A, C, and D are incorrect. Cephalocaudal pattern refers to the principle of development from head to toe, not relevant in explaining differences between twins. Cephamodistal pattern is not a recognized developmental term. Gene-environment correlation does not directly explain the differences between identical twins raised in the same environment.

Correct Answer: C

Rationale: The correct answer is C: 'Ambivalent.' Children with an ambivalent temperament are indeed generally mild but hesitant about accepting new experiences. This temperament is characterized by a combination of mildness and hesitance. Choice A, 'Secure,' refers to children who are comfortable with both their caregiver's presence and absence, showing a secure attachment style. Choice B, 'Avoidant,' describes children who tend to avoid or ignore their caregiver, displaying an insecure attachment style. Choice D, 'Disorganized,' represents children with inconsistent or confused behaviors towards their caregiver, exhibiting an insecure and disoriented attachment style.

Correct Answer: B

Rationale: Humanists believe in the inherent goodness and potential of individuals. They would most likely say that Manny can become more assertive by improving his self-esteem and recognizing his abilities. Choice A is incorrect because humanists focus on self-actualization rather than deep-seated feelings of inferiority. Choice C is incorrect as it oversimplifies the issue by suggesting a training class can solve the problem without addressing underlying beliefs. Choice D is incorrect as it suggests a psychoanalytic approach, while humanists usually emphasize personal growth and self-improvement.
