Consciousness of targets during the attentional blink: a gradual or all-or-none dimension?
Models of consciousness differ in whether they predict a gradual change or a discontinuous transition between nonconscious and conscious perception. Sergent and Dehaene (Psychological Science, 15, 720-728, 2004) asked subjects to rate on a continuous scale the subjective visibility of target words presented during an attentional blink. They found that these words were either detected as well as...
متن کاملIs consciousness a gradual phenomenon? Evidence for an all-or-none bifurcation during the attentional blink.
Several theories of the neural correlates of consciousness assume that there is a continuum of perception, associated with a gradual change in the intensity of brain activation. But some models, considering reverberation of neural activity as necessary for conscious perception, predict a sharp nonlinear transition between unconscious and conscious processing. We asked participants to evaluate t...

متن کاملThe delayed consolidation hypothesis of all-or-none conscious perception during the attentional blink, applying the ST framework
There is evidence that conscious perception during the attentional blink is all-or-none, which contrasts with the finding of a continuum of perceptual strength in masking experiments. This seems to reveal the underlying representation of strength that can be found in the brain in the absence of attentional enhancement. We provide electrophysiological support for this all-or-none theory. Then, u...
متن کاملConsciousness as a graded and an all-or-none phenomenon: A conceptual analysis.
The issue whether consciousness is a graded or an all-or-none phenomenon has been and continues to be a debate. Both contradictory accounts are supported by solid evidence. Starting from a level of processing framework allowing for states of partial awareness, here we further elaborate our view that visual experience, as it is most often investigated in the literature, is both graded and all-or...
