Sažetak
Introduction: Deficits in area of communication, crucial for maintaining proper social bonds, may have a prominent adverse
impact on quality of life in patients with schizophrenia. Social exclusion, lack of employment and deterioration of family life, may be consequences of aggravated social competencies, caused by inability to properly exhibit and interpret facial expressions. Although this phenomenon is known since first clinical descriptions of schizophrenia, lack of proper methodology limited our knowledge in this area. Aim of our study was to compare facial expressivity of the patient with schizophrenia, and the healthy individual.
Methods: 47-years old patient suffering from schizophrenia, and 36-years old healthy individual were invited to participate in
our study. They underwent the examination in Human Facial Modelling Lab in Polish-Japanese Institute of Information Technology in Bytom (Silesia, Katowice). Both participants were presented with two video materials, first one contained different facial expressions, which they had to imitate. Second one a part of comedy show, during which spontaneous reactions were recorded. Acquisition of facial expressions was conducted with marker-based technology of modelling. Obtained data was analyzed using Microsoft Excel.
Results and conclusions: An overall facial expression intensity, expressed as an average value of distances traveled by markers
during shifts from neutral position was higher in case of a healthy participant during both part of the study. The difference was
especially visible in case of an upper half of the face. Utilization of marker-based methods in analysis of human facial expressions seem to be reliable and remarkably accurate.
