Positive symptoms are experiences added to normal functioning, such as disturbances in thinking, speech, or behavior. Disorganized speech exemplifies this because when thinking becomes fragmented, speech can become illogical, incoherent, or derail into unrelated topics. This reflects an excess or distortion of normal thought processes. In contrast, flat affect, social withdrawal, and anhedonia are negative symptoms, representing reductions or losses in normal functions like emotional expression, social engagement, and the ability to feel pleasure. So, disorganized speech is the positive symptom among the options.
