Tapping regularity as a measure of perceptual motor load.

摘要: Numerous methods have been devised to measure perceptual load. Unfortunately the concept itself is ill-defined, which makes different approaches practically incomparable. The central problem ordering of tasks types. Most compare that differ only in one variable, such as speed or input/output uncertainty. There are however can be applied a wider range tasks. One approach observes timing successive actions: load will cause ‘ traffic control’ problems nervous system, so actions executed an irregular fashion. use irregularity depends on availability functional ’ descriptive system behaviour, opposed current phenomenal systems like those time and motion study. A convenient substitute ia measuring subsidiary performance. Key tapping was found satisfy certain methodological requirements. Some experiments evaluating this...
