Anhedonia, or diminished pleasure, in schizophrenia is most apparent 
when it comes to anticipating future events. People with 
schizophrenia report expecting less pleasure from enjoyable 
activities, and experience less pleasure when anticipating future 
events, than people without schizophrenia. However, when actually 
doing these pleasant activities, people with and without 
schizophrenia report experiencing the same amount of pleasure. The 
example of anhedonia in schizophrenia illustrates that pleasure is 
not a single process. Instead, pleasure emerges from a host of 
interacting cognitive, affective and motivational systems, 
dysfunction in any one of which can lead to problems with pleasure.
