The detection of multiple global directions: capacity limits with spatially segregated and transparent-motion signals.

abstract：:When a stimulus is presented, its sensory trace decays rapidly, lasting for approximately 1000 ms. This brief and labile memory, referred as iconic memory, serves as a buffer before information is transferred to working memory and executive control. Here we explored the effect of different factors--geometric, spatial,...
