Motion-onset visual evoked potentials predict performance during a global direction discrimination task

▶ Multiple epochs in the motion-related visual evoked potential make significant independent contributions to the prediction of response latency ▶ These epochs can be related to cognitive models of motion perception and perceptual decision-making ▶ The relationship between these epochs and a diffusion process model indicate that model estimates of information accumulation rate reflect both early and late processes, not only a post-perceptual decision process.
