What are positive signs of shizophrenia?

Positive symptoms typically involve behaviors that are either inappropriate or unusual behavior (e.g., acting very odd) such as delusions (i.e., illogical thoughts or beliefs not held by others), hallucinations (i.e., seeing, hearing, feeling things that are not there), disorganized speech such as a rambling flow of thought (“word salad”), agitation (i.e., being more active than usual, but without having a purpose), or inappropriate emotional responses (not matching expressions with behaviors).
