The relationships among cognition, motivation, and emotion in schizophrenia: how much and how little we know.
This article summarizes a workshop discussion focused on the current state of our understanding of the ways in which cognitive dysfunction in schizophrenia is related to, influenced by, or even leads to disturbances in areas such as emotion, motivation, and stress, as well as areas in need of further research. A major emphasis in the workshop discussion was the critical importance of motivation and its potential influence on cognitive function and learning in schizophrenia. As such, the members of the workshop suggested a number of questions regarding motivation that need further research, including (1) the definition and measurement of different components of motivation; (2) the relationship between intrinsic motivation and incentive drive and hedonic processing; (3) the integrity of motivational processes, incentive drive, and hedonic processing in schizophrenia; (4) the influence of cognitive deficits on motivational disturbances in schizophrenia; (5) the influence of antipsychotic medication on incentive drive and hedonic processing in schizophrenia; and (6) the relationships among cognitive function, stress, and the processing of aversive stimuli.
