| summary | The flash-lag effect and different sorts of mislocalisation of moving stimuli have been often interpreted as the result of a mental extrapolation mechanism, aimed at compensating for the neural transmission delay. Whether the postulated mechanism rests on a spatial or temporal basis, and whether it operates through an extrapolation constant or a variable parameter remains however a matter of debate. We contend herein that lack of suitable measurement of "perception-for-action" lies at the source of the problem, and that a solution can be obtained by coupling the methodology of Information Integration Theory with tasks where a motor localization response is required. In doing so, the extrapolation mechanism can be recast as a psychophysical problem, and proper estimation of a temporal extrapolation constant follows from the established properties of the psychophysical function. |
