Dot cancellation test
|Dot cancellation test|
|Purpose||test visual perception|
The test has been used in the evaluation of stroke where subjects were instructed to cross out all groups of 4 dots on an A4 paper. The numbers of uncrossed groups of 4 dots, groups of dots other than 4 crossed, and the time spent (maximum, 15 minutes) were taken into account. The Group-Bourdon test, a modification of the Bourdon-Wiersma, is one of a number of psychometric tests which trainee train drivers in the UK are required to pass.
