Invariant Time Course of Priming With and Without Awareness.

The findings reported in this paper show that perceptual measures based on conscious reports do not suffice to determine whether some information is or is not available to the visual system at large. Instead, motor and perceptual effects can be become perfectly dissociated. This indicates that relevant stimulus attributes are fully processed up to the level of response control but remain unavailable for conscious report. It is also clear that classical psychophysical measures do not necessarily reflect all information available to the visual system, and they should be supplemented by performance measures that do not tap perceptual awareness. We believe that our approach of contrasting direct and indirect performance measures and of dissociating perception and action by their time courses may provide, in conjunction with neurophysiological and functional brain imaging approaches, a more complete picture of information processing within the visual system.
