Which of the following describes a verbal indicator of psychosis?

Disorganized, incoherent speech serves as a verbal indicator of psychosis because it reflects the individual’s impaired thought processes and difficulties in organizing their thoughts and language. In cases of psychosis, a person's ability to express themselves coherently can be significantly hindered, resulting in speech that may seem jumbled, fragmented, or illogical. This symptom is often associated with conditions such as schizophrenia or severe mood disorders, where the individual's ability to process information and communicate effectively is compromised. Recognizing this type of speech can be crucial for identifying individuals in need of further evaluation or intervention.

The other options represent characteristics of normal cognitive function. Clear and logical thought processes indicate mental clarity and organization, while consistent memory recall and spontaneous humor reflect stable cognitive and emotional states, which are not indicative of psychosis.
