Abstract
El objetivo de este estudio fue investigar la relación entre la tasa de respuestas y los patrones de activación cortical en la integración de tareas usando los pares de expresiones faciales. Los participantes emitieron un juicio sobre una gráfica y la calificaron en una escala de intensidad afectiva que transmitía dos expresiones faciales, cada una se presentó a uno de los dos hemisferios usando la técnica de Divides Visual Field (DVF). Mientras ellos realizaban la tarea, fue grabada su respuesta en el EEG usando 6 electrodos. Tres emociones discretas fueron consideradas (Alegría, Miedo y Rabia) y estas variaron en tres niveles de intensidad de la expresión. Varios pares de caras contenían la misma emoción, otras dos mostraban emociones diferentes. Los patrones de integración de las dos fuentes de información fueron examinadas tanto con las escalas como con las respuestas cerebrales (ERD) grabadas en cada seguimiento del EEG. El patrón de la regla de la adición fue observado en las calificaciones de pares de emociones iguales y pares de emociones diferentes. La integración de tipo aditivo fue comúnmente observada cuando el Į -ERD fue tomado como una respuesta. Los resultados fueron discutidos teniendo en cuenta la lateralización de los procesamientos emocionales y las relaciones entre la R observable y los posibles aspectos prácticos de R propuestos por la Teoría de Integración de la Información (IIT).
