Measuring facial expression of emotion
Abstract
Research into emotions has increased in recent decades, especially on the subject of recognition of emotions. However, studies of the facial expressions of emotion were compromised by technical problems with visible video analysis and electromyography in experimental settings. These have only recently been overcome. There have been new developments in the field of automated computerized facial recognition; allowing real-time identification of facial expression in social environments. This review addresses three approaches to measuring facial expression of emotion and describes their specific contributions to understanding emotion in the healthy population and in persons with mental illness. Despite recent progress, studies on human emotions have been hindered by the lack of consensus on an emotion theory suited to examining the dynamic aspects of emotion and its expression. Studying expression of emotion in patients with mental health conditions for diagnostic and therapeutic purposes will profit from theoretical and methodological progress.
En las últimas décadas se ha incrementado la investigación sobre las emociones, especialmente en el tema del reconocimiento de ellas. Sin embargo, los estudios sobre la expresión facial de la emoción estaban distorsionados de manera notoria por problemas técnicos en los análisis de videos y de electromiografías en situaciones experimentales. Esto solo recientemente ha sido superado. Ha habido nuevos desarrollos en el área del reconocimiento facial computarizado automático; lo que permite una identificación en tiempo real de la expresión facial en ambientes sociales. Esta revisión aborda tres propuestas para la medición de la expresión de la emoción y describe sus contribuciones específicas para la comprensión de ella en población sana y en personas con enfermedad mental. A pesar de los progresos recientes, los estudios sobre emociones humanas han tenido obstáculos por la falta de consenso acerca de una teoría de la emoción adecuada para examinar los aspectos dinámicos de la emoción y su expresión. El estudio de la expresión de emociones en pacientes con patologías mentales con fines diagnósticos y terapéuticos se beneficiará de los avances teóricos y metodológicos.
Ces dernières années, la recherche sur les émotions se développe, surtout en ce qui concerne la reconnaissance des émotions. Les études sur les expressions faciales des émotions rencontrent cependant des problèmes techniques, l'analyse vidéo visible et l'électromyographie, seulement récemment maitrisées, étant encore au stade expérimental. Les nouveaux développements dans le domaine de la reconnaissance faciale automatisée et informatisée permettent une identification en temps réel de l'expression faciale dans les environnements sociaux. Cet article s'intéresse à trois façons de mesurer l'expression faciale de l'émotion et décrit leurs contributions spécifiques à la compréhension de l'émotion dans la population saine et chez les personnes atteintes d'une maladie mentale. Malgré des progrès récents, les études sur les émotions humaines ont été gênées par le manque de consensus sur une théorie de l'émotion adaptée à l'examen de ses aspects dynamiques et de son expression. L'étude de l'expression de l'émotion chez les patients atteints de pathologies mentales dans un but diagnostique et thérapeutique bénéficiera de ce progrès théorique et méthodologique.
