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: Subjective distress is not universal among individuals with a mental disorder. Choice A is incorrect as not all individuals with mental illness experience distress. Choice B is incorrect because distress is just one of the criteria used in diagnosing abnormality, not the only one. Choice C is incorrect because the presence of subjective distress alone is not sufficient for a clinician to determine if someone has a mental illness.

Correct Answer: C

Rationale: The correct diagnosis for Roger's condition is Broca's aphasia. Broca's aphasia is characterized by difficulty in speaking fluently and accurately, often due to brain injury. In this case, Roger's symptoms of being unable to speak fluently, mispronouncing words, and speaking haltingly align with the characteristics of Broca's aphasia. Agnosia refers to the inability to recognize or interpret sensory information, spatial neglect is the lack of awareness of one side of the body or space, and prosopagnosia is the inability to recognize faces, none of which match Roger's symptoms.

Correct Answer: C

Rationale: The correct answer is C: Reference. A delusion of reference is when an individual believes that external events or characters are sending them personal messages. In this scenario, David's belief that characters from the science fiction show are sending him messages aligns with a delusion of reference. Choices A, B, and D are incorrect because persecution delusions involve feeling targeted or harassed, influence delusions involve believing external forces are controlling one's thoughts or actions, and grandeur delusions involve an exaggerated sense of importance or power.

Correct Answer: D

Rationale: Dr. Rice's views align with William James, a functionalist, who emphasized understanding the role emotions play in survival and adaptation. William James and other functionalists believed that emotions have a purpose in helping individuals adapt to their environment. Edward Titchener, known for structuralism, focused on the structure of the mind rather than the purpose of emotions. Ivan Pavlov was a behaviorist known for his work on classical conditioning, which is not directly related to the purpose of emotions. Carl Rogers was a humanistic psychologist who emphasized self-actualization and personal growth, not specifically the purpose of emotions in survival and adaptation.
