Modeling perceptual discrimination in dynamic noise: Time-changed diffusion and release from inhibitionJournal of Mathematical Psychology - Tập 59 - Trang 95 - 2014
Ratcliff Roger, Sewell David K., Smith Philip L.
The speed and accuracy of discrimination of featurally-defined stimuli such as letters, oriented bars, and Gabor patches are reduced when they are embedded in dynamic visual noise, but, unlike other discriminability manipulations, dynamic noise produces significant shifts of RT distributions on the time axis. These shifts appear to be associated with a delay in the onset of evidence accumulation b...... hiện toàn bộ
