Construcción y validación del Repositorio de Expresiones Faciales Emocionales Colombianas

Abstract

Phenotypic traits affect the response to emotional faces. In Colombia, an image bank of emotional faces has not been built and validated. The objective of this study was to build and validate a bank of photographs of Colombian emotional faces (joy, anger, sadness, fear, disgust, surprise and neutral expression/rest), through a methodology similar to that used in the design of other banks of emotional expressions. The study was carried out with 80 participants (43 women), to whom each of the 70 emotional expressions of the Repository of Colombian Emotional Facial Expressions (REFEC) was presented. From previous studies in this field, the percentage of correctness and the Fleiss kappa coefficient (degree of agreement between evaluators) were taken as validity indices. Additionally, reaction time was measured as an index of cognitive demand for the recognition of emotional expression. The results show a percentage of correctness higher than that of other stimulus banks of emotional expressions and a good / excellent concordance index (similar to that of other instruments). Together, the results suggest that REFEC is a valid image bank of emotional facial expressions for use in the Colombian population.
