Resumen

Antecedentes: confi ar en otras personas es necesario para una relación satisfactoria. La percepción de confi anza por parte del observador en otra persona aumenta cuando la cara expresa alegría. Investigamos en qué medida la confi anza depende de la expresión de los ojos en caras con una sonrisa. Método: presentamos vídeo-clips de expresiones dinámicas, con diferentes combinaciones de la expresión en la boca (sonrisa o neutra) y los ojos (alegres, neutros, de sorpresa, tristeza, miedo, asco y enfado). Los participantes juzgaban cuán contenta o de fi ar parecía la persona observada. Resultados: tanto los juicios de alegría como los de confi anza, y sus tiempos de reacción, variaron en función de pequeños cambios en los ojos, y de la naturaleza de éstos; los de enfado produjeron las mayores reducciones en alegría y confi anza. Conclusiones: la percepción de alegría es más dependiente de una boca sonriente, mientras que la percepción de confi anza depende más de la expresión en los ojos. La desconfi anza aumenta especialmente por la incongruencia entre ojos y boca
