Oriet and Jolicoeur (2003) proposed that an endogenous task-set reconfiguration process acts as a hard bottleneck during which even early perceptual processing is impossible. We examined this assumption using a psychophysiological approach. Participants were required to switch between magnitude and parity judgment tasks within a predictable task…

Two experiments with 11 college students demonstrate the influence of their prior visual adaptation to motion on the imagined speed of an imaginary moving object. Results suggest that imagined motion and real vision may engage common neural mechanisms without being functionally equivalent. (SLD)
