## Description

This digital modification of the Bourdon-Wiersma test is a commonly used test of combined visual perception and vigilance.

The test has been used in the evaluation of stroke where subjects were instructed to check all groups of four dots. The number of groups of dots other than four needs to be pushed away by hitting the x button, and the time spent (maximum, 15 minutes) is taken into account.
