Studies of Measures of Attention

NCT00776737 COMPLETED

This study will compare two tests for attention deficit disorder (ADD) - the Test of Variables of Attention (TOVA) and the NIH Test of Attention - to see if they produce the same results. There are a number of problems with existing tests for ADD. For example, TOVA, the most commonly used test, operates only on older computers and has other problems as well. Because of these problems, NIDCD developed the new NIH Test of Attention. This study will determine if the new test is valid for ADD and how the performance on this test compares to the performance on the TOVA in the general population. Healthy volunteers between 6 and 60 years of age who have no problems with sight or hearing and are not taking medication for ADD may be eligible for this study. After a brief interview, participants take the first of the two study tests. On a second visit, they take the other of the two tests. Both tests ask the subject to respond to things they hear and see on a computer screen. Each test takes 30 to 45 minutes to complete. Some participants are asked to take the NIH Test of Attention a second time, on a third visit. Participants also take a 15- to 20-minute subtest of the Weschler Intelligence Test.
