La amplitud perceptual, definida como la zona alrededor del punto de fijación de la que se extrae información funcional para el procesamiento, es mayor a la derecha que a la izquierda de éste, al menos cuando se procesa material verbal. Esta asimetría en la amplitud perceptual ha sido puesta de manifiesto con diferentes paradigmas experimentales que revisamos en este trabajo. Revisamos igualmente las distintas hipótesis que se han propuesto para su explicación, para concluir con algunas implicaciones que este dato pudiera tener para otros estudios que utilizan presentación de material verbal en parafóvea.
