Disordered communication of emotions belongs to the primary schizophrenia symptoms. The aim of this study was our attempt of the localisation of the deficits in emotional communication (its decoding and expression) in dimensional models of schizophrenia. The evaluation of emotionality in schizophrenia might be performed indirectly via negative dimension (for instance: apathy, diminished verbal fluency, flat or inappropriate emotional reactions), via excitement (elevated mood) and depression (decreased mood) or via cognitive dimension. Interpretation of emotional phenomena within the cognitive dimension remains an oversimplification. Brain emotional and cognitive systems act independently although they also reveal mutual interactions enabling the control of emotional behaviour via social learning of emotions. To conclude, to date emotional dimension in schizophrenia has not yet received satisfactory explanation which is in line with the complex nature of emotions. Thus the question regarding the location of emotions in dimensional models of schizophrenia still remains open.
