Exam 4 Psychology

Correct Answer: C

Rationale: According to the diathesis-stress model, having a predisposition towards mental illness increases the risk but does not guarantee the development of a mental disorder. Choice A is incorrect as the model does not imply certainty. Choice B is incorrect as having a predisposition does affect the chances. Choice D is incorrect as the model does have an impact on the likelihood of developing a mental disorder.

Correct Answer: C

Rationale: In individuals with schizophrenia, blunted affect, or reduced emotional expression, is a common symptom. In this scenario, Charles's lack of emotional response upon hearing about his sister's death aligns with the characteristic of blunted affect. This symptom can manifest as a limited range of facial expressions, monotone voice, and reduced display of emotions. Choice A, 'Clang associations,' refers to a thought disorder characterized by the use of words that sound alike but are not logically connected. Choice B, 'Echolalia,' is the repetition of words spoken by others. Choice D, 'Perseveration,' is the persistent repetition of a response or behavior even when it is no longer appropriate.

Correct Answer: A

Rationale: The correct answer is A: Savant skills. Savant skills refer to exceptional abilities commonly observed in individuals with autism. These skills can include remarkable talents in areas such as mental math, memorization, music, and art. Choice B, Theory of mind, is the ability to attribute mental states to oneself and others, which is a different concept. Choice C, Echolalia, is the repetition of words or phrases, not related to exceptional abilities. Choice D, Self-stimulatory behaviors, involves repetitive body movements or sounds often seen in individuals with autism but is not directly related to exceptional mental abilities.

Correct Answer: B

Rationale: Selective mutism can coexist with social anxiety disorder. The correct answer is B because it is incorrect to say that selective mutism cannot be diagnosed alongside social anxiety disorder. Statement A is true as selective mutism is often associated with high social anxiety. Statement C is true as individuals with selective mutism can speak in some situations. Statement D is true as selective mutism may lead to academic impairment due to difficulties in communication.

Correct Answer: C

Rationale: The correct answer is the Hypothalamus (Choice C). The hypothalamus plays a crucial role in regulating basic bodily functions such as hunger, thirst, and sleep. It receives cues related to these needs and helps to maintain homeostasis in the body. The Hippocampus (Choice A) is primarily involved in memory formation and spatial navigation, not in regulating physiological needs. The Thalamus (Choice B) acts as a relay station for sensory information but is not the main center for hunger, thirst, or sleep regulation. The Amygdala (Choice D) is more associated with emotions, particularly fear and pleasure, rather than physiological needs like hunger, thirst, or sleep.
