Perceptual consciousness and cognitive access
The question of how our subjective experiences (colours as we see them; sounds as we hear them; tastes as we feel them, etc.) can be accounted for in terms of brain processes is regarded as one of the biggest unsolved problems in science. One of the most pressing questions is whether the neural basis of this ‘perceptual consciousness’ is independent of the neural basis of cognitive access mechanisms that make reporting and reflecting on conscious experiences possible. Subjective experiences are directly available only to the individual having them, so subjective reports seem to be the only measure of being conscious. However, if perceptual consciousness is independent of the access mechanisms underlying subjective reports, then the neural correlates of reporting will confound experiments relying on subjective reports to measure the presence of conscious experiences.
This theme issue focuses on this central problem of consciousness research by bringing together a cohort of international experts to tackle this question from neural, behavioural and theoretical perspectives. The papers critically discuss state-of-the-art empirical findings, identify methodological problems and propose novel approaches.
