Figure 2. Implications of dynamic spatial attention on feature perception and object integrity.

Figure 2.

Cartoon depicting simplified tasks and results from [27, 26, 61]. Top: When attention must be covertly shifted from one location to another (dark gray to black box), and the stimulus array is presented 50ms after the shift cue, subjects either report the correct features or misreport (swap) the features of the distractor at the initially attended location, but object integrity is preserved. Middle: When covert attention is simultaneously split across two different locations and subjects are post-cued to report one of them, feature reports may be distorted (e.g. blend of both colors), and object integrity is degraded (e.g. reporting color of one item and orientation of the other). Bottom: When covert attention must be maintained at a spatiotopic location (black) while executing an eye movement (white arrow) elsewhere, and the stimulus array is presented 50ms after the eye movement, interference is seen from the distractor at the retinotopic trace location (dark gray). Errors here are consistent with those seen during splitting of attention, suggesting spatial attention is temporarily highlighting both the spatiotopic and retinotopic trace locations after a saccade.
