Temporal Response Of The Human Visual System To Suprathreshold Luminance And Opponent Colour Contrast Gratings, Melanie Bucking
Theses and Dissertations (Comprehensive)
The goal of the present study was to characterize the temporal processing of both suprathreshold luminance and opponent-colour defined contrast in the human visual system. We used a detection task in five experiments; following a 900 Hz, 2-cycle tone, observers were presented with a sinusoidal grating stimulus. The interval separating the waming tone and the presentation of the grating was manipulated to determine the influences of attentional dwell time in a cross-modal task. This theory states that the first of two successive events will interfere with the processing of the second event. In all four luminance experiments the gratings were …
