Disentangling the effects of spatial inconsistency of targets and distractors when searching in realistic scenes.

abstract：:A range of visual illusions, including the much-studied flash-lag effect, demonstrate that neural signals coding for motion and position interact in the visual system. One interpretation of these illusions is that they are the consequence of motion extrapolation mechanisms in the early visual system. Here, we study th...
