The Wikipedia describes these symptoms as follows for those of us who have no idea what you're talking about...
Schizophrenia is often described in terms of positive and negative (or deficit) symptoms. The term positive symptoms refers to symptoms that most individuals do not normally experience. They include delusions, auditory hallucinations, and thought disorder, and are typically regarded as manifestations of psychosis. Negative symptoms are so-named because they are considered to be the loss or absence of normal traits or abilities, and include features such as flat or blunted affect and emotion, poverty of speech (alogia), inability to experience pleasure (anhedonia), lack of desire to form relationships (asociality), and lack of motivation (avolition). Research suggests that negative symptoms contribute more to poor quality of life, functional disability, and the burden on others than do positive symptoms.
Despite the appearance of blunted affect, recent studies indicate that there is often a normal or even heightened level of emotionality in schizophrenia, especially in response to stressful or negative events. A third symptom grouping, the disorganization syndrome, is commonly described, and includes chaotic speech, thought, and behavior. There is evidence for a number of other symptom classifications.
Personally I think we all move from positive to negative symptoms as we progress in our condition. I found that after I started taking meds I moved from more positive to more negative symptoms and even developed a state of chronic depression for which I now have to take anti-depressants as well.
