The objective of this study was to find out whether error feedback can affect Representational Momentum (RM). Participants viewed a target that exhibited leftward or rightward implied motion. A probe then appeared, either at the same location where the target had disappeared, or at a different location. In Experiment 1, participants in feedback absent and feedback present conditions, were assigned to six groups each, on the basis of the location of the different probe from the point of disappearance of the target. In Experiment 2, participants were shown the probes at different distances, in separate trials. The findings support the hypothesis that RM reflects a partially modular or cognitively impenetrable process, as error feedback did not reduce RM. Greater displacement for rightwards motion of the target may indicate that reading habits can influence directionality in motion perception, as proposed earlier. Participants in Experiments 1 and 2 were more likely to indicate same for probes presented ahead than behind the final inducing stimulus.
