AB Persons who suffer from schizophrenia have difficulties in recognizing emotions in others’facial expressions, which affects their capabilities for social interaction and hinders theirsocial integration. Photographic images have traditionally been used to explore emotionrecognition impairments in schizophrenia patients, but they lack of the dynamism thatis inherent to facial expressiveness. In order to overcome those inconveniences, overthe last years different authors have proposed the use of virtual avatars. In this work,we present the results of a pilot study that explored the possibilities of using a realisticlookingavatar for the assessment of emotion recognition deficits in patients who sufferfrom schizophrenia. In the study, 20 subjects with schizophrenia of long evolution and20 control subjects were invited to recognize a set of facial expressions of emotionsshowed by both the said virtual avatar and static images. Our results show thatschizophrenic patients exhibit recognition deficits in emotion recognition from facialexpressions regardless the type of stimuli (avatar or images), and that those deficitsare related with the psychopathology. Finally, some improvements in recognition rates(RRs) for the patient group when using the avatar were observed for sadness or surpriseexpressions, and they even outperform the control group in the recognition of thehappiness expression. This leads to conclude that, apart from the dynamism of theshown expression, the RRs for schizophrenia patients when employing animated avatarsmay depend on other factors which need to be further explored.
