Aspectos metodológicos de la evaluación subjetiva de la carga mental de trabajo

Abstract

Objetivo: El objetivo de este trabajo es evaluar las propiedades psicométricas de tres instrumentos de medida subjetiva de la carga mental de trabajo: NASA-TLX, SWAT y WP. Material y métodos: La muestra estuvo formada por 36 sujetos que realizaron dos tareas experimentales, de forma separada y simultáneamente. Las dos tareas experimentales fueron una tarea de búsqueda en la memoria de Sternberg y una tarea de seguimiento (tracking). Resultados: Los resultados demostraron que: a) los tres instrumentos evaluados fueron sensibles a las manipulaciones realizadas en la dificultad de la tarea, revelándose la técnica WP como la mejor; b) el poder diagnóstico de WP y SWAT fue claramente superior al obtenido por TLX, y c) la validez convergente de los tres fue elevada
