The aim of the program is to identify how the client reacts in an active stress situation.
Using clicks of the mouse the client assesses the shape, color and accompanying acoustic signal of a geometric figure that moves about the screen. The computer continuously adapts the speed of presentation to the client's performance. This subjects the client to the optimum level of persistent stress.
The level of difficulty can be adapted to the client's performance by various means, such as by removing the audio signal or adjusting the program's settings so that it does not respond immediately to changes in performance.
Since the client uses the mouse in this procedure, the system can also identify the effects of working position and stress on the musculature.
The vertical markers indicate the mistakes made by the client during the tolerance test. The chart shows that the client responds to mistakes with a sudden rise in skin conductance (yellow).
