Implicaciones clínicas del uso del tamaño pupilar como indicador de actividad psicológica: una breve revisión

Abstract

Since the 60's, pupil reactivity has been used in Psychology as a psychophysiological index of cognitive and emotional processing. In this paper, we provide a brief review from early and controversial studies focused on studying the effect of different types of stimuli on pupil size to the latest research that has used this index as a measure of affective processing in different psychological disorders. We also review studies that link mental activity or cognitive load with pupil dilations. We discuss the clinical implications of the use of this simple psychophysiological index.
