All-or-none conscious perception and the Attentional Blink

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, using principles from the ST2 model of temporal attention and working memory, we show how this all-or-none pattern can be explained by the delayed target consolidation that is known to arise during the attentional blink.
