3. Hemsley (1993) suggested schizophrenics cannot distinguish between information that is already stored and new incoming information. As a result, schizophrenics are subjected to sensory overload and do not know which aspects of a situation to attend to and which to ignore. When schizophrenics first hear voices and experience any other worrying sensory experiences, they turn to their friends and relatives to confirm the validity of what they are experiencing. Some people fail to confirm the reality of these experiences, so the schizophrenic comes to believe they must be hiding the truth. Individuals then begin to reject feedback from those around them and develop delusional beliefs that they are being manipulated and persecuted. The role of biological factors is acknowledged in this explanation – it says that the condition has always existed, but is worsened by those around themCognitive Explanation
