Exam 4 Psychology
1. Which neurotransmitter is reduced in both the manic and depressive phases of bipolar disorder?
- A. Acetylcholine
- B. Dopamine
- C. Norepinephrine
- D. Serotonin
Correct answer: D
Rationale: The correct answer is D, Serotonin. Serotonin levels are reduced during both the manic and depressive phases of bipolar disorder. Acetylcholine (choice A) is not typically linked to bipolar disorder. Dopamine (choice B) and norepinephrine (choice C) are more commonly associated with conditions like schizophrenia and depression, respectively, rather than bipolar disorder. Therefore, they are not the neurotransmitters reduced in both manic and depressive phases of bipolar disorder.
2. How is binge-eating disorder different from bulimia?
- A. Typically eat much smaller portions before purging the food.
- B. Do not typically purge the food they eat.
- C. Only purge their food after several binge sessions.
- D. Often resort to anorexic methods to rid themselves of the food they have eaten.
Correct answer: B
Rationale: The correct answer is B because individuals with binge-eating disorder do not typically engage in purging behavior, unlike those with bulimia. Choice A is incorrect as individuals with binge-eating disorder do not purge the food they eat, so they do not eat smaller portions before doing so. Choice C is incorrect as they do not purge their food after several binge sessions. Choice D is incorrect as individuals with binge-eating disorder do not resort to anorexic methods to rid themselves of the food they have eaten.
3. Which part of your brain is active when you get cues about being hungry, thirsty, or sleepy?
- A. Hippocampus
- B. Thalamus
- C. Hypothalamus
- D. Amygdala
Correct answer: C
Rationale: The correct answer is the Hypothalamus (Choice C). The hypothalamus plays a crucial role in regulating basic bodily functions such as hunger, thirst, and sleep. It receives cues related to these needs and helps to maintain homeostasis in the body. The Hippocampus (Choice A) is primarily involved in memory formation and spatial navigation, not in regulating physiological needs. The Thalamus (Choice B) acts as a relay station for sensory information but is not the main center for hunger, thirst, or sleep regulation. The Amygdala (Choice D) is more associated with emotions, particularly fear and pleasure, rather than physiological needs like hunger, thirst, or sleep.
4. 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.
5. What term describes exceptional mental abilities such as mental math, memorization, musical, and artistic ability found among individuals with autism?
- A. Savant skills
- B. Theory of mind
- C. Echolalia
- D. Self-stimulatory behaviors
Correct answer: A
Rationale: The correct answer is A: Savant skills. Savant skills refer to exceptional abilities commonly observed in individuals with autism. These skills can include remarkable talents in areas such as mental math, memorization, music, and art. Choice B, Theory of mind, is the ability to attribute mental states to oneself and others, which is a different concept. Choice C, Echolalia, is the repetition of words or phrases, not related to exceptional abilities. Choice D, Self-stimulatory behaviors, involves repetitive body movements or sounds often seen in individuals with autism but is not directly related to exceptional mental abilities.
