1. While out for a walk, you come across a ferocious dog. You feel your heart beating faster and your palms begin to sweat. Which part of the peripheral nervous system is activated in this situation?

• A. Autonomic
• B. Sympathetic
• C. Parasympathetic
• D. Somatic

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.

2. What is extinction and how might it be used in treating a disorder?

• A. Extinction strengthens the conditioned response by continuously pairing the conditioned stimulus with the unconditioned stimulus.
• B. Extinction is the process of eliminating a conditioned response by repeatedly presenting the conditioned stimulus without the unconditioned stimulus.
• C. Extinction is ineffective and is not used in treating disorders.
• D. Extinction is the process of intensifying the conditioned response by pairing the conditioned stimulus with a stronger unconditioned stimulus.

Correct answer: B

Rationale: The correct answer is B. Extinction is the process of eliminating a conditioned response by repeatedly presenting the conditioned stimulus without the unconditioned stimulus. This helps in reducing or eliminating undesired behaviors. Choice A is incorrect because extinction does not strengthen the conditioned response but weakens it. Choice C is also incorrect as extinction is a valid technique used in treating disorders by reducing unwanted behaviors. Choice D is incorrect as extinction does not involve intensifying the conditioned response but rather diminishing it.

3. Marissa wants to study people's emotional reactions to increases in temperature. Her classmate, Bernard, tells her that she should focus on observable behaviors rather than internal states in her study. Bernard's views are most similar to those found in?

• A. The psychodynamic perspective.
• B. The evolutionary perspective.
• C. The behavioral perspective.
• D. The biological perspective.

Correct answer: C

Rationale: Bernard's advice to focus on observable behaviors aligns with the behavioral perspective. Behaviorists emphasize studying external actions rather than internal states to understand human behavior. The psychodynamic perspective (Choice A) focuses on unconscious processes, the evolutionary perspective (Choice B) on adaptation and natural selection, and the biological perspective (Choice D) on the biological underpinnings of behavior, making them less similar to Bernard's suggestion.

4. How does the concept of neural plasticity relate to recovery from brain injuries?

• A. Neural plasticity means the brain cannot recover from injuries.
• B. Neural plasticity allows the brain to recover and reorganize after injuries.
• C. Neural plasticity refers to the brain's inability to change after injury.
• D. Neural plasticity is a myth.

Correct answer: B

Rationale: Neural plasticity allows the brain to recover and reorganize after injuries. It is the brain's ability to adapt and change, forming new connections or reorganizing existing ones to compensate for damage. Choice A is incorrect as neural plasticity enables recovery. Choice C is incorrect as neural plasticity involves the brain's capacity to change. Choice D is incorrect as neural plasticity is a well-established phenomenon in neuroscience.

5. In order for one to be diagnosed with panic disorder, the panic attacks must?

• A. Suddenly; unexpectedly
• B. Suddenly; gradually
• C. Gradually; unexpectedly
• D. Unexpectedly; suddenly

Correct answer: A

Rationale: The correct answer is A: 'Suddenly; unexpectedly.' Panic disorder is diagnosed when panic attacks occur unexpectedly, not gradually. Panic attacks are characterized by their sudden onset and are unpredictable. Choice B is incorrect because panic attacks do not manifest gradually. Choice C is incorrect because panic attacks are not expected or predicted. Choice D is incorrect as well because the unexpected nature of panic attacks is a key criterion for diagnosing panic disorder.
