The time course of cued target identification was measured in different feature dimensions. Spatially cued targets were generally identified in short time windows which varied between features and observers, but attention could also be held for later targets if the cued location was empty or the requested information not yet available. For orientation, color, and luminance polarity, but not for motion, target properties were faster seen than cues detected; instead of reporting the properties of the physically cued target observers reported the properties of a later target at the cued location. That is, the effective cuing windows were delayed. Different directions of target movement, however, were identified about in synchrony with the cue. These differences confirm earlier reports of an asynchronous perception of color, orientation, and motion. In the context of cued visual selection (CVS), the experiments confirm that cuing and cued target selection provide a spatially and temporally relatively precise access to the dynamics of neural processes in visual perception.
