Previous work has shown that, in the absence of focal attention, simple features (e.g., colors) can be misbound to incorrect locations. Here we show that attention-demanding cues in the periphery can repulse these features to be incorrectly seen at locations closer to fixation. Participants were cued with a shape (circle or square) either in the left or right periphery before seeing a horizontal array of diamonds in the center of the screen (a pair of diamonds on each side of fixation, each with one gray and one colored diamond). Participants reported the shape of the cue, and which two colors appeared at which of the four diamond locations. When the cue was absent or at fixation, participants were accurate in reporting the locations of both colored diamonds. But attending to peripheral cues created a perceptual repulsion, where colors on that side of fixation were consistently misperceived closer to fixation (and farther away from the cue). This illusion was found to be even stronger when the cue was presented in the right hemifield compared to the left hemifield, revealing an attentional hemifield asymmetry for the binding of simple features.
