what is the biopsychosocial model and why is it important

ATI RN

Psychology 2301 Exam 1

1. What is the biopsychosocial model, and why is it important?

A. A model that integrates biological, psychological, and social factors.
B. A model that focuses solely on biological factors.
C. A model that excludes social factors.
D. A model that focuses solely on psychological factors.

Correct answer: A

Rationale: The biopsychosocial model is a model that integrates biological, psychological, and social factors. It is important because it recognizes the interconnectedness of these factors in influencing an individual's mental health. Option B is incorrect because the biopsychosocial model does not focus solely on biological factors. Option C is incorrect as the model does not exclude social factors. Option D is incorrect as the model does not focus solely on psychological factors.

2. The understanding of genetic influences on behavior may never be fully achieved due to ________.

A. the ease of researching to differentiate between the effects of the environment and genes.
B. the likelihood that most behaviors are determined by the interaction of many genes and the environment.
C. the reliance on twin studies in genetic research.
D. our significant understanding of how genes impact brain chemistry.

Correct answer: B

Rationale: The correct answer is B because most behaviors are influenced by the interaction of multiple genes and the environment. Choice A is incorrect because it suggests that researching the effects of the environment and genes is easy, which is not the case. Choice C is incorrect as it focuses on a specific method (twin studies) rather than the broader concept of gene-environment interaction. Choice D is incorrect as the statement implies a high level of understanding that contradicts the idea that genetic influences on behavior may never be fully understood.

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. What are protective factors? Give an example of one and explain how it can impact a person's later functioning.

A. Protective factors are influences that modify a person's response to environmental stressors, making adverse consequences less likely.
B. An example of a protective factor is having a warm and caring parent, which may lead to resilience.
C. Protective factors usually lead to resilience, the ability to adapt successfully to stressful circumstances.
D. Protective factors always prevent the development of psychopathology.

Correct answer: B

Rationale: Protective factors are influences that modify a person's response to environmental stressors, reducing the likelihood of adverse outcomes. An example of a protective factor is having a warm and caring parent, which can foster resilience in individuals. Resilience allows individuals to adapt successfully to stressful situations. Choice A is incorrect as protective factors do not always prevent adverse consequences but reduce their likelihood. Choice C is incorrect as resilience is the outcome of protective factors, not the other way around. Choice D is incorrect as while protective factors can reduce the risk of psychopathology, they do not always prevent its development.

5. 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.
