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.

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.

Correct Answer: A

Rationale: The correct answer is A: Catatonia. Catatonia is a symptom seen in some cases of schizophrenia, characterized by motor abnormalities such as peculiar hand and limb movements or adopting unusual postures for extended periods. Choice B, Loose association, refers to a thought disorder where ideas shift from one subject to another in an unrelated way. Choice C, Disorganized speech, is characterized by incoherent or incomprehensible speech patterns. Choice D, Blunted affect, describes a reduction in the intensity of emotional expression.

Correct Answer: D

Rationale: The correct answer is Dopamine. Dopamine was initially thought to be the primary cause of schizophrenia. This neurotransmitter hypothesis was based on the observation that drugs that increase dopamine activity can worsen symptoms of schizophrenia, while drugs that decrease dopamine activity can improve symptoms. Choices A, B, and C are incorrect because GABA, serotonin, and epinephrine were not the neurotransmitters initially believed to be the cause of schizophrenia.
