Abstract Within the dorsal stream account of visuomotor control, the role of visual awareness in guiding action remains controversial. We argue that addressing this question requires considering how action demands influence the processing of task-relevant visual information. Accordingly, we conducted two experiments in which participants performed a reaching movement to match their hand orientation to that of a briefly presented Gabor patch.

Abstract Disclosing the brain areas responsible for the emergence of visual awareness and their timing of activation represents one of the major challenges in consciousness research. In particular, isolating the neural processes strictly related to consciousness from concurrent neural dynamics either related to prerequisites or post-perceptual processing has long engaged consciousness research.
