It is a psychiatric diagnosis that describes a mental disorder characterized by abnormalities in the perception of expression of reality. There are several signs and symptoms, which makes diagnosis of this disorder easier. Firstly, a schizophrenic usually will suffer from delusions and hallucinations.
Secondly, schizophrenics often think in disorganised and fragmented ways. Their emotions and behaviour are similarly disorganised and illogical at times. For example, if a schizophrenic is told sad news he may laugh instead of showing appropriate emotions.
Thirdly, schizophrenics suffer from disturbances of their emotions. Both their positive and negative emotions lack normal intensity. For example, if told that a relative has passed away they may be indifferent to the news.
Or if asked a simple question that seems harmless they may become agitated and violent. Lastly, they may have lack motivation and interest in life. Psychologists have attempted to explain schizophrenia via a number of theories.

This makes them very destructible and results in their disorganized cognition. Humans have limited information-processing capacity, which means we need some way of purposefully selecting what information to process. The impairment of the selective attention mechanism would result in the senses constantly being flooded with information.
For example, the bizarre use of language in schizophrenics could be a result of a fault of the way in which information is processed.In all I 've learned, the subject of what exactly America was before it officially became America was never covered as extensively as it should have been.
