What is one of the nonverbal indicators of psychosis?

Delusions are indeed a significant indicator of psychosis, as they represent a disconnect from reality and involve strongly held beliefs that are not based in factual evidence. Individuals experiencing delusions may firmly believe in things that are untrue or impossible, such as conspiracies involving themselves or paranoid ideas about others' intentions. This symptom is a core aspect of psychotic disorders and is typically accompanied by other manifestations of psychosis, like hallucinations and disorganized thinking.

In contrast, happiness in social settings, clear communication of information, and increased physical activity do not inherently indicate psychosis. Happiness generally suggests stable mental health, clear communication indicates coherent thinking and cognitive function, and increased physical activity might not be related to psychotic symptoms unless linked to other behavioral changes in the context of a mental health issue. Hence, delusions stand out as a key nonverbal indicator associated specifically with psychotic conditions.
