Exam 4 Psychology 101

Correct Answer: B

Rationale: The correct answer is B: Sympathetic. When encountering a stressful situation like a ferocious dog, the sympathetic nervous system is activated, leading to the 'fight or flight' response. This response triggers physiological changes like increased heart rate, sweating, and heightened alertness to prepare the body to deal with the perceived threat. The autonomic nervous system (Choice A) encompasses both the sympathetic and parasympathetic divisions, so it's a broader category. The parasympathetic nervous system (Choice C) is responsible for the body's 'rest and digest' functions, which are opposite to the physiological changes seen in a stress response. The somatic nervous system (Choice D) controls voluntary movements and sensory information, not the physiological responses seen in a stress reaction.

Correct Answer: A

Rationale: Colleen's behavior of seeking attention and manipulating others by threatening self-harm to elicit a response from her psychology instructor aligns with the characteristics of borderline personality disorder. This disorder is characterized by unstable relationships, impulsive actions, and efforts to avoid real or imagined abandonment. Choices B, C, and D are incorrect because they do not match Colleen's behavior as described in the scenario. Schizoid personality disorder is characterized by a lack of interest in social relationships, Schizotypal personality disorder involves social anxiety and odd behavior, and Antisocial personality disorder is characterized by a disregard for others' feelings and violating their rights.

Correct Answer: D

Rationale: John Watson was a key figure in the development of behaviorism, which advocated for focusing on observable behavior rather than the study of consciousness. Choice D is the correct answer because Watson believed that psychology should abandon the study of consciousness. Choices A, B, and C are incorrect because Watson's approach emphasized behavior and rejected the importance of consciousness, introspection, or confining psychology to only mentally ill individuals.

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: A

Rationale: Oliver's roommate holds a humanistic perspective. This perspective emphasizes human uniqueness and may devalue information obtained from animal studies when studying human experiences. The humanistic perspective focuses on subjective experiences, free will, and personal growth, which aligns with his roommate's belief that animal studies won't provide meaningful information about human experiences. Choice B, an evolutionary perspective, would focus on the role of evolution in shaping behavior, not directly related to the roommate's view. Choices C and D, biological and cognitive perspectives respectively, do not directly address the roommate's skepticism toward using animal studies to understand human motivation.
