Capacity limits in conscious perception: Cognitive and neural mechanisms

Henry Railo, PhD, University of Turku

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?
