The perception of temporal order can be influenced by retrospective stimulation

When judging the order of presentation of the two visual stimuli (targets), if a preceding cue was presented around one of the targets, the target on the cue side was judged to have been given first (the pre-cue effect). In Experiment 1, a cue was presented after the target. As a result, it was found that the target on the cue side was judged to be presented later (post-cue effect). Experiment 2 confirmed the replicability of the post-cue effect by manipulating target-target onset asynchrony. Experiment 3 showed a post-cue effect in simultaneity judgments, demonstrating the robustness of this effect. The post-cue effect demonstrates that the process of judging temporal order or simultaneity is sensitive to stimulation shortly after the task-relevant stimuli, and may suggest that this process relates to the detection of movement direction.
