BayEst-01

Behavioural data and functional brain activity (EEG) recorded from 36 healthy, adult humans as they engaged in a simple perceptual decision-making task. The stimulus displays comprised a set of randomly moving dots within a circular aperture at the screen centre. On every trial, a short period of coherently moving dots was presented and participants had to report whether the net motion direction was shifted clockwise or counterclockwise relative to a response criterion in the form of two collinear bars shown on the perimeter of the circular aperture. Both response speed and accuracy were emphasized. Each participant completed about 1,000 trials.
