Is an erroneous belief that is fixed and firmly held delusion; despite clear contradictory evidence. negative symptom; during periods of psychosis. hallucination; by people with schizophrenia.

The correct answers are delusion; despite clear contradictory evidence.

Answer 1: A delusion is an erroneous or unfounded belief that a person is convinced of. Delusions are beliefs that are usually fixed and firm in a person's mind. An example of a delusion is strongly believing and being convinced that someone is "out to get you" because of far-fetched scenarios and beliefs you have conjured up in your imagination (you arrived at this belief without any external evidence).  

Answer 2: Another aspect of delusions is that they are firmly held despite clear contradictory evidence. Let's consider the previous example again: You believe that someone is out to get you and you hold this belief with strong conviction even when there is no evidence supporting it. For instance the person you feel threatened by has not behaved or acted in any way to suggest that they might harm or hurt you.However, despite this, you still believe that he or she is out to get you.

In this way, a delusion is an erroneous belief that is fixed and firmly held despite clear contradictory evidence. 

"Delusion"  "Despite"

Explanation:

Schizophrenia is a destructive psychical disturbance that is described by major violence in feeling, attention, sensation, and reaction.

A hallucination means such perceptual occurrence which happens in the lack of outside stimulation.

Delusions are opinions that are against the existence and are strongly kept steady in the aspect of conflicting testimony. Many of us keep opinions that some would think odd, but a delusion is undoubtedly recognized because it is obviously ridiculous.
