ABSTRACT:
A testing method and apparatus for determining the reaction time of machine operators, especially drivers of automotive vehicles. A series of images are projected onto a viewing screen to be observed by a student at a student station. The images comprise one or more visual depictions of various operating conditions, including non-threatening and threatening conditions. After presenting a sequence of non-threatening conditions images, an "action cue image" representing a threatening condition is projected. The elapsed time between the projection of the action cue image and the initiation of the required response of the student is measured to derive the student's reaction time, in terms of seconds or distance traveled at a specified speed.
