Capacity limits in conscious perception: Cognitive and neural mechanisms

Henry Railo, PhD, University of Turku

GOAL:
Cognitive processes are known to shape the contents of conscious perception, but some have argued that they form the very core of conscious vision. In my postdoc studies I aim to elucidate the neural foundations of cognitive capacity limitations in conscious perception: What factors limit the capacity of conscious perception? Is the timing of conscious perception fixed, or subject to processing limitations?
