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. Who founded functionalism?

A. John Watson.
B. Sigmund Freud.
C. William James.
D. Wilhelm Wundt.

Correct answer: C

Rationale: William James is credited with founding functionalism, which emphasizes the adaptive purpose of consciousness. John Watson is associated with behaviorism, not functionalism. Sigmund Freud is known for psychoanalysis, and Wilhelm Wundt is considered the founder of modern psychology and structuralism, not functionalism.

3. Which of the following did Freud believe played a causal role in the development of most forms of psychopathology?

A. Anxiety
B. Depression
C. Unresolved conflicts between the ego and the superego
D. Fixation in the oral stage

Correct answer: A

Rationale: Freud believed that anxiety was a primary causal factor in the development of most forms of psychopathology. Anxiety, according to Freud, arises from conflicts within the mind, particularly conflicts between the id, ego, and superego. This unresolved conflict can lead to various psychological issues. While depression can be a symptom of psychopathology, Freud emphasized anxiety as a more foundational element. Unresolved conflicts between the ego and the superego are related to Freud's structural model of the mind but are not the primary causal factor in psychopathology. Fixation in the oral stage is a concept from Freud's psychosexual stages of development and is not directly linked to the causal role in the development of most forms of psychopathology.

4. 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.

5. What role does culture play in understanding abnormal behavior?

A. Culture plays a minimal role in understanding abnormal behavior.
B. Culture is essential in shaping our perceptions and definitions of abnormal behavior.
C. Culture has little impact on the expression of abnormal behavior.
D. Culture only affects the treatment of abnormal behavior, not its understanding.

Correct answer: B

Rationale: Culture is essential in shaping our perceptions and definitions of abnormal behavior. Choice A is incorrect because culture actually plays a significant role in understanding abnormal behavior. Choice C is incorrect as culture can have a considerable impact on how abnormal behavior is expressed. Choice D is incorrect because culture influences not only the treatment but also the understanding of abnormal behavior.
