Application

Measures perceptual speed and peripheral vision.
The WG is a tachistoscopic picture comparison test and makes it possible to differentiate between a client's central and peripheral vision. This is relevant when the traffic maturity of adolescents or the fitness to drive of adults needs to be determined. However, it is also possible to test perceptual speed in the area of sports and suitability assessment with the WG.

Administration

The respondent sees two pictures at short intervals which differ in three details. The respondent must mark the differences to the first image perceived in the second picture.
The pictures come from traffic situations and everyday situations (S1) or only represent traffic situations (S2).

Test forms

S1: Standard form.
S2: Standard form traffic.
