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?

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.

Correct Answer: C

Rationale: The correct answer is C: Reference. A delusion of reference is when an individual believes that external events or characters are sending them personal messages. In this scenario, David's belief that characters from the science fiction show are sending him messages aligns with a delusion of reference. Choices A, B, and D are incorrect because persecution delusions involve feeling targeted or harassed, influence delusions involve believing external forces are controlling one's thoughts or actions, and grandeur delusions involve an exaggerated sense of importance or power.

Correct Answer: C

Rationale: The correct diagnosis for Roger's condition is Broca's aphasia. Broca's aphasia is characterized by difficulty in speaking fluently and accurately, often due to brain injury. In this case, Roger's symptoms of being unable to speak fluently, mispronouncing words, and speaking haltingly align with the characteristics of Broca's aphasia. Agnosia refers to the inability to recognize or interpret sensory information, spatial neglect is the lack of awareness of one side of the body or space, and prosopagnosia is the inability to recognize faces, none of which match Roger's symptoms.

Correct Answer: C

Rationale: Gabriel's reaction of turning down the offer of job interview books from his friend despite being depressed and unsuccessful in job hunting best fits the concept of learned helplessness. Learned helplessness occurs when individuals believe they have no control over their situation, leading to passivity and feelings of helplessness. In this case, Gabriel's refusal of the books indicates a sense of resignation and belief that his efforts in finding a job will not be successful, reflecting learned helplessness. Observational learning, insight learning, and modeling do not directly align with Gabriel's reaction in this context.

Correct Answer: C

Rationale: The correct answer is C, Flooding. Flooding is an exposure therapy technique where a person is exposed to their fear at full intensity until the fear subsides. In this scenario, Bella is exposed to her fear of balloons in a controlled environment until she realizes her fear is unjustified. Choice A, Systematic desensitization, involves gradual exposure to the fear stimulus paired with relaxation techniques. Choice B, Aversion therapy, aims to create a negative association with a stimulus to reduce unwanted behavior. Choice D, Extinction, refers to the gradual decrease in the strength or frequency of a conditioned response.
