Correct Answer: B

Rationale: The correct answer is B: Positive symptoms. Positive symptoms in schizophrenia are behaviors or experiences that are added to normal functioning, such as hallucinations and delusions. These symptoms are considered 'positive' because they represent an excess or distortion of normal functions. Choices A, C, and D are incorrect. Flat affect refers to a reduction in emotional expression, negative symptoms involve deficits in normal functioning such as reduced emotional expression or motivation, and catatonia is a state of unresponsiveness.

Correct Answer: D

Rationale: The correct answer is D, Edward Titchener. Dr. Asgaard's belief aligns with Titchener's approach of structuralism, which emphasizes understanding the components of consciousness. William James (choice A) was associated with functionalism, focusing on the purpose of behavior rather than its structure. Ivan Pavlov (choice B) was known for classical conditioning in behaviorism, not structuralism. Carl Rogers (choice C) was a major figure in humanistic psychology, emphasizing personal growth and self-actualization, which is not directly related to understanding component parts of processes.

Correct Answer: D

Rationale: The correct answer is D, Sigmund Freud. Freud's psychoanalytic theory emphasized the impact of unconscious motivations on behavior. Carl Rogers (choice A) is known for person-centered therapy emphasizing self-actualization, Wilhelm Wundt (choice B) is a structuralist in psychology focusing on consciousness, and B.F. Skinner (choice C) is associated with behaviorism and operant conditioning, which do not primarily focus on unconscious motivations.

Correct Answer: A

Rationale: William James was heavily influenced by Charles Darwin's theory of evolution, which shaped his functionalist views on psychology. This influence is evident in James's emphasis on adaptation, survival, and the functional purposes of behavior. Choice B, Sigmund Freud, is incorrect because Freud's psychoanalytic theory focused on unconscious processes and childhood experiences, which differ significantly from James's functionalism. Choice C, John Watson, is incorrect as Watson was a behaviorist who emphasized observable behavior and rejected mental processes, which contrasts with James's focus on mental processes. Choice D, B.F. Skinner, is also incorrect as Skinner was a behaviorist known for his work on operant conditioning, which is not directly aligned with James's functionalist perspective.

Correct Answer: C

Rationale: The correct answer is C: Humanists. Humanistic psychologists emphasize individual uniqueness, freedom, and the potential for personal growth. They believe in the importance of personal experiences and self-actualization. Behaviorists (choice A) focus on observable behaviors and environmental influences. Psychoanalysts (choice B) are more concerned with unconscious processes and early childhood experiences. Gestalt psychologists (choice D) concentrate on perception and the organization of experience, rather than individual uniqueness and personal growth.
