In searching for the target-afterimage patch among spatially separate alternatives of color-afterimages the target fades from awareness before its competitors (Bachmann, T., & Murd, C. (2010). Covert spatial attention in search for the location of a color-afterimage patch speeds up its decay from awareness: Introducing a method useful for the study of neural correlates of visual awareness. Vision Research 50, 1048–1053). In an analogous study presented here we show that a similar effect is obtained when a target spatial location specified according to the direction of motion aftereffect within it is searched by covert top-down attention. The adverse effect of selective attention on the duration of awareness of sensory qualiae known earlier to be present for color and periodic spatial contrast is extended also to sensory channels carrying motion information.
► Motion aftereffects (MAEs) for gratings with different directions of motion were produced. ► In the Search condition subjects reported whether the cued direction MAE ended before other MAEs. ► In the Monitoring condition subjects reported which one of the uncued MAEs ended before any other. ► Selective attention in Search shortened the MAE relative to its duration in Monitoring. ► The known adverse effect of attention on afterimage awareness is extended to visual motion.
