Sam hears the voice of Satan telling him what to do. This symptom of schizophrenia is called a __________.

A) schizoid break
B) hallucination
C) disturbance of attention
D) delusion
E) negative symptom

A hallucination is a sensory experience (such as seeing, hearing, or feeling something) that seems real but does not actually exist outside of the mind. In this case, Sam is hearing the voice of Satan, which is not based in reality. A delusion, on the other hand, is a false belief that persists despite evidence to the contrary. A schizoid break and disturbance of attention are not specific symptoms of schizophrenia, and negative symptoms refer to a reduction or loss of normal abilities or behaviors, such as lack of emotional expression or motivation.
