Unconscious processing revealed by visual masking
Unconscious processing revealed by visual masking
Although the visibility of the form and surface features of a temporally prior stimulus can be completely suppressed by a temporally following one, some pre- or non-conscious processing of the former nonetheless survives perceptual suppression. Among these are neural processes that enable it to be located in the visual field, to contribute to motion perception, and to act, in turn, as a mask of a third stimulus. Moreover, a masked stimulus can pre-consciously prime feature-selective responses to the form or color of a probe stimulus following the following masked one. The suppressive effects of visual masking can be systematically related to other techniques of rendering stimuli invisible, such as binocular-rivalry suppression or application to transcranial magnetic stimulation to the occipital pole.
