Psychology 101 Exam 3 Test
1. How do neurotransmitters affect behavior and mental processes?
- A. Neurotransmitters have little effect on behavior.
- B. Neurotransmitters are chemicals that influence mood, thought, and behavior.
- C. Neurotransmitters have a minor role in mental health.
- D. Neurotransmitters determine intelligence levels.
Correct answer: B
Rationale: Neurotransmitters are chemicals that influence mood, thought, and behavior, playing a significant role in mental health. Choice A is incorrect as neurotransmitters do have a notable effect on behavior. Choice C is incorrect as neurotransmitters have a major role in mental health. Choice D is incorrect as neurotransmitters do not solely determine intelligence levels.
2. Professor Immel believes that behaviors that are predominant in certain species probably serve some adaptive function. Professor Immel's beliefs are most consistent with which perspective?
- A. Behavioral perspective.
- B. Cognitive perspective.
- C. Humanistic perspective.
- D. Evolutionary perspective.
Correct answer: D
Rationale: Professor Immel's belief that behaviors in certain species serve an adaptive function aligns with the evolutionary perspective. The evolutionary perspective posits that behaviors have developed over time because they provide an advantage for survival and reproduction. This perspective emphasizes the role of natural selection in shaping behaviors based on their adaptive value. Choices A, B, and C do not specifically address the idea that behaviors have evolved to serve specific functions for survival, making them inconsistent with Professor Immel's beliefs.
3. How does stress impact brain function?
- A. Stress has no effect on brain function.
- B. Stress can lead to changes in brain structure and function.
- C. Stress can improve brain function.
- D. Stress has no long-term impact on brain function.
Correct answer: B
Rationale: Stress can lead to changes in brain structure and function, affecting mental health and increasing the risk of disorders. Choice A is incorrect as stress does affect brain function. Choice C is incorrect as stress generally has negative impacts on brain function rather than improving it. Choice D is incorrect because stress can have long-term impacts on brain function through structural and functional changes.
4. The site of chemical communication in the brain is the ________.
- A. neuron
- B. synapse
- C. axon
- D. dendrite
Correct answer: B
Rationale: The synapse is the correct answer. It is the site where communication between neurons occurs through the release and reception of neurotransmitters. Choice A, neuron, is incorrect as it is the cell itself rather than a specific site of communication. Choice C, axon, is also incorrect as it is a part of the neuron that transmits signals away from the cell body. Choice D, dendrite, is not the correct answer either, as dendrites receive signals from other neurons but do not release neurotransmitters for communication.
5. How does the biopsychosocial model differ from the biomedical model?
- A. The biopsychosocial model focuses solely on the biological aspects of disease.
- B. The biopsychosocial model includes biological, psychological, and social factors, whereas the biomedical model focuses on only biological factors.
- C. The biopsychosocial model is outdated and has been replaced by the biomedical model.
- D. The biopsychosocial model is identical to the biomedical model.
Correct answer: B
Rationale: The biopsychosocial model differs from the biomedical model by considering biological, psychological, and social factors in understanding health and illness. Choice A is incorrect because the biopsychosocial model does not solely focus on biological aspects. Choice C is incorrect as the biopsychosocial model is not outdated but rather offers a more comprehensive approach. Choice D is incorrect as the two models are distinct in their considerations of factors beyond biology.
