Which statement correctly differentiates hallucinations from delusions?

• A. Hallucinations are fixed false beliefs; delusions are misperceptions of real stimuli.
• B. Hallucinations are sensory experiences without external stimuli; delusions are fixed false beliefs despite evidence.
• C. Hallucinations are deliberate lies patients tell; delusions are normal beliefs.
• D. Hallucinations and delusions are the same phenomenon.

Answer: (B)

Hallucinations are sensory experiences that occur without any external stimulus, so the person perceives something real to them even though nothing there is actually present. Delusions, on the other hand, are fixed false beliefs that persist despite clear evidence to the contrary and are not rooted in perception. This distinction matters: hallucinatory experiences are about perception, while delusions are about belief.

For example, hearing voices when no one is speaking illustrates a hallucination, whereas believing one is being persecuted despite evidence to the contrary illustrates a delusion. The statement in question correctly captures that difference by describing hallucinations as sensory experiences without external stimuli and delusions as fixed false beliefs despite evidence. The other options mix up perception and belief (or describe delusions as lies or normal beliefs) and don’t reflect this distinction.
