1. Dr. Lee is studying pain perception using a functionalist perspective. It is most likely that Dr. Lee would suggest that we can only understand the conscious experience of pain?

• A. If all the component parts that make up the experience of pain are understood.
• B. By observing the outward expression of pain in response to different stimuli.
• C. If we first understand the role of pain in human survival and adaptation.
• D. If we understand the unconscious processes that initiate the sensation of pain.

Correct answer: C

Rationale: The functionalist perspective, as used by Dr. Lee, focuses on understanding the role of pain in human survival and adaptation. This perspective suggests that to fully comprehend pain perception, one must first grasp the significance of pain in terms of its adaptive functions and impact on behavior. Choices A, B, and D do not align with the functionalist perspective, as they do not emphasize the role of pain in human survival and adaptation.

2. A psychological disorder is said to have an acute onset if the symptoms develop ______, while it has an insidious onset if the symptoms develop ______.

• A. Suddenly;gradually
• B. Suddenly;atypically
• C. Gradually;atypically
• D. Atypically;suddenly

Correct answer: A

Rationale: An acute onset refers to the sudden development of symptoms, whereas an insidious onset indicates a gradual progression of symptoms. Therefore, the correct answer is 'Suddenly;gradually.' The other choices are incorrect because 'atypically' does not accurately describe the onset of symptoms in this context.

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. Albert has brown eyes, even though one of his biological parents has blue eyes. Genes for blue eyes are part of Albert's ___.

• A. Phenotype
• B. Zygote
• C. Genotype
• D. Environment

Correct answer: C

Rationale: Albert's genotype refers to the genetic makeup inherited from his parents, which includes the genes for blue eyes. The phenotype, on the other hand, is the observable trait, in this case, brown eyes. Therefore, the correct answer is C. Choice A (Phenotype) is incorrect as it refers to the observable characteristics, not the genetic information. Choice B (Zygote) is incorrect as it refers to the initial stage of a developing organism. Choice D (Environment) is incorrect as it does not directly determine eye color.

5. Where is the site of chemical communication in the brain?

• A. Neuron
• B. Synapse
• C. Axon
• D. Dendrite

Correct answer: B

Rationale: The correct answer is B: Synapse. The synapse is the site where chemical communication occurs between neurons. Neurotransmitters are released from the axon terminal of one neuron, cross the synaptic cleft, and bind to receptors on the dendrites of the next neuron. Choice A, Neuron, is incorrect as it refers to the entire nerve cell. Choices C and D, Axon and Dendrite, are also incorrect as they are specific parts of a neuron and not the primary site of chemical communication.
