Executing saccades result in shifts of objects’ retinal locations. However, our visual system isefficient in correcting these shifts and enabling us to perceive a stable world. Transsaccadic object correspondence was originally tested with the intrasaccadic target displacement paradigm (Bridgeman, et al., 1975) in which the saccade target’s spatial location is shifted during the saccade. Participants are asked to report the direction of the shift. Previous studies have consistently found that perception of shift detection is poor unless the target object’s continuity is disrupted during the saccade. For instance, disrupting the target’s continuity by removing it for a brief period after the saccade (i.e., blanking the target) results in significantly more accurate reports of shift direction (Deubel et al., 1996). Other studies have shown that changing target’s surface features, such as shape (Demeyer et al., 2010), contrast polarity (Tas et al., 2012), or changing the target’s identity (Tas et al., 2012) result in similar improvements in displacement detection performance. However, a more recent study has found that orientation does not improve performance, suggesting that not all features may contribute to transsaccadic object correspondence (Balp et al., 2018). In the present study, we tested whether color changes can disrupt target’s continuity and result in improved displacement detection performance. We employed thetarget displacement paradigm where the target’s continuity is not disrupted (no-blank), its continuity is disrupted with a blank, or its continuity is disrupted with a color change. We also manipulated the magnitude of color change (ranging from 15° to 180°). Preliminary results suggest that small color changes (e.g., 15°) are not sufficient to disrupt target’s continuity. However, as the magnitude of color change increased, displacement detection performance improved. These results demonstrate that not all features are consulted for transsaccadic object correspondence, and only salient changes disrupt visual stability across saccades.
