Is conscious perception continuous or discrete?  Asplund et al use the attentional blink paradigm to demonstrate that conscious perception is discrete and quantal. Attention increases the probability that a representation will reach awareness.

We have argued that cognition is discrete and quantal because the backbone of neural communication used for cognition is oscillatory.  For this discussion see:

Professor Miller uses experimental and theoretical approaches to study the neural basis of the high-level cognitive functions that underlie complex goal-directed behavior. His focus is on the frontal lobe, the region of the brain most... learn more »
