Which dimension describes whether a hallucination is voluntary or involuntary?

• A. Voluntary or involuntary
• B. Colorfulness
• C. Duration
• D. Source of memory

Answer: (A)

The dimension being tested is agency—the level of control a person has over the percept. A hallucination described as voluntary implies some intentional involvement or the person’s ability to produce or accept the percept on demand. Involuntary means it arises without deliberate action or consent, occurring spontaneously.

Colorfulness would refer to how vivid or sensory-rich the hallucination is, not who controls it. Duration concerns how long the hallucination lasts. Source of memory relates to whether a memory is coming from internal recall or an external source, not the issue of voluntary control.
