Measurement of Perceptual Motor Load Using the Interval Production Task

Abstract This study investigates the use of the interval production task as a secondary task for the quantification of perceptual motor load. In this case, the variability in foot tapping is used as the index of performance in the secondary task. Experiments investigating the effect of tasks of varying motor and perceptual loads on tapping are reported. The study concludes that although the interval production task can be used to differentiate between motor loads, its utility as an index of perceptual load is questionable.
