Con frecuencia, se ha venido recurriendo al enmascaramiento retroactivo central para estudiar la microgénesis de la percepción visual. El recurso a esta técnica venía justificado porque, al asumir que la aparición de la máscara interrumpía el procesamiento del estímulo-objetivo, permitía explorar las etapas tempranas del proceso perceptual. Sin embargo, el hecho de que ordinariamente se utilizara como criterio de percepción el informe directo de los sujetos, junto con los resultados de experimentos recientes que indican que el enmascaramiento no interrumpe el proceso perceptual en sí, sino que impide el conocimiento del estímulo percibido, obliga a una distinción entre perception y experiencia consciente de un estímulo, por una parte, y al consiguiente replanteamiento del enmascaramiento como técnica para descubrir la microgénesis perceptual, por otra. La revisión y puesta al día de estas cuestiones constituyen el contenido de este trabajo.
