Speaker information

Dr Hakwan Lau

Host:UCL Institute of Cognitive Neuroscience Seminar Series.

A signal detection theoretical model explains why the less you attend, sometimes the more you subjectively 'see' (may be why subjects were often surprised at how poor they were at detecting targets outside of the focus of attention). The model is supported by data from psychophysics, brain imaging, transcranial magnetic stimulation, and intracranial electrophysiology. It assumes that attention reduces the trial-by-trial variability of the internal neural response. This has implications for both neuronal population coding for perception, as well as philosophical debates on the nature of conscious awareness.
