Temporal recalibration to delayed visual consequences of saccades

Temporal recalibration is a fascinating phenomenon. If one (experimentally) induces a consistent artificial delay between an action (e.g., pressing a button) and a visual stimulus (e.g., the light turning on), then - after a few exposures - stimuli occuring at shorter delays may well appear as if they happened even before the action was executed. In this piece Wiebke shows temporal recalibration across a good range of visual conditions with not only real but also simulated saccades.

Associated information increases subjective perception of duration

The temporal oddball effect – that is, the phenomenon that the duration of an oddball stimulus is overestimated when compared to the duration of a standard stimulus which is repeatedly presented in a stream – is thought to be driven by prediction errors. Suprisingly, and in contrast to this predominant hypothesis, we found that a more predictable oddball object (e.g., a pizza following a pizza cutter) is overestimated to a larger degree than a fully unpredictable oddball (e.g., a rubber duck following a pizza cutter). How could this be explained?
