D2 Test of Attention explained
| D2 Test of Attention |
| Purpose: | measure of selective and sustained attention |
The d2 Test of Attention is a neuropsychological measure of selective and sustained attention and visual scanning speed.[1] It is a paper and pencil test that asks participants to cross out any letter "d" with two marks around above it or below it in any order.[2] The surrounding distractors are usually similar to the target stimulus, for example a "p" with two marks or a "d" with one or three marks.[3] The original version of the test was created by Brickenkamp (1981) in Germany as a cancellation task.[4] A meta-analysis, published in Personality and Individual Differences, found that adults have shown increasing scores in selective attention over the past three decades, as measured by the d2 Test of Attention.[5]
