The Reactive Agility Test

A new agility task incorporating the variations in the stimulus field and the instrumentation for measurement of performance is described. Reliability coefficients are very high (.838 to .973) The stimulus variations that emanate from the spatial and temporal uncertainties progressively increase the level of task difficulty. The described apparatus provides for adjustments in the amplitude of the task and in the control of spatial and temporal uncertainties to suit the requirements of a specific investigation.
