To be honest here, I am a bit biased because this attention test was developed and computerized by myself and it is now published by my own company Pyramid Productions. The TODA is one of the attention tests developed to measure divided attention: doing more than two things at once. The Trail Making Test is one of the most used neuropsychological tests in the Western world.
The Symbol Digit Modalities Test is a very much used attention test, just like the Trail Making Test. The results we show for the keyword Eeg Test Results will change over time as new trends develop in the associated keyword catoegory and market. Therefore, I would like to review tests which in my opinion should be used the most because of their proven ability to measure attention deficits in patients and normal (healthy) persons.Furthermore, I would like to discuss some well-known and well-used attention tests that - in my opinion - are overrated.
Nevertheless, it still has several qualities and is therefore used as an example of a fine test.It is an 8-minute computerized auditory sustained attention test in which you will here 240 groups of 2, 3, or 4 beeps.
The National Institute of Mental Health states the attention deficit disorder, or ADD, and attention deficit hyperactivity disorder, or ADHD, are often missed by parents and educators. I would like to point out serious weaknesses of such tests and urge clinicians to use other attention tests for the sake of patients.
We do have the Paced Auditory Serial Addition Task (PASAT) but there are several problems with this test, although this task is used a lot in scientific research papers.
It can also be used in severely visually impaired patients and severe aphasic patients.But of course, as with other attention tests, improvements can still be made as well.
It has even made it into Nintendo DS Brain Trainer game, thereby seriously reducing its usability as a neuropsychological test due to practice effects a lot of elderly and adults have with this test.Although very popular in clinical practice (and research studies), I have my reservations with this test due to my experiences with it.
Secondly, the SDMT is very sensitive to any kind of brain injury and can therefore be used as a good screening instrument for further elaborate neuropsychological testing. Lawrence Greenberg, a child psychiatrist at the University of Minnesota, in the 1960s as part of his effort to design a plan for diagnosing and treating ADHD. When you look at my five criteria for a good neuropsychological test (see my page on Test-Psychology): reliability, validity, standardization, availability and usability it scores reasonably well on reliability, standardization, availability and usability. The original test was administered on a machine that assessed the user’s speed at responding to visual images.


In my opinion, the test then does not really measure what it should measure and the differentiation between patients and healthy controls becomes a serious problem.
Some might even say that flexibility is required to constant switching of the responses.It has some learning effects but the TODA can be repeated in a couple of months without having too much test-retest effects.
The advantage is that it surely can detect sustained attention problems, much better than most very short attention tests (like SDMT or TMT).The disadvantage is that many patients with brain injury will not like this test or even be able to complete it because it is very boring. The test asks the user to respond to visual images within a limited timeframe (approximately 10 minutes for younger children and 21 minutes for older children, adolescents or adults). If half-way a patient falls asleep or gets really annoyed and does not respond anymore, the test really does not measure what it is supposed to measure. Norms for this test are doubtful, often only on a small number of healthy controls or brain injured patients. It seems to be too short so sustained attention can not be measured properly with this attention test.
This attention test is 8-minutes long and that turned out to be sufficiently long to measure quite sensitively concentration problems.
But one of the most serious problems with this PASAT is that this test is certainly not user friendly.
Furthermore, patients with visual inattention or otherwise visually impaired can not be tested reliably with this test. Just as with the TOSSA the large sample of 1700 individuals is put together more conveniently than with stratified sampling (unfortunately, a lot of tests are). Practice effects are quite serious when administering the test with a very short time interval. Usually, a ratio of 3 or higher is used.In my own study, in which I compare several tests like the TMT, Stroop, d2, Digit-span and the new tests TOSSA and TODA, the much used ratio score is NOT very sensitive. Other fine examples are the TOVA (Test of Variables of Attention), the IVA (Integrated Visual and Auditory CPT) and the Connors CPT. In some studies doing the test twice can result in 18 to 20% improvement!The TODA is much more user friendly: it can be done for more brain injured patients than the PASAT.
I must say this was only tested in 70(!) normal volunteers and it is usually the case that in normals reliability coefficients can be lower than in patient groups. I wonder whether the test-retest reliability of the IVA would be higher in clinical groups (in the TOSSA it IS higher). A serious shortcoming of the TOVA is that it is currently unavailable for Windows Vista and Windows7.


This lack of for example correlations between the IVA and other well-known attention tests is very serious because now it can not be established how well the IVA can assess attentional problems.
People with ADHD may use alcohol or drugs to deal with social insecurities, calm anxiety, or help them focus more effectively.Futures may not provide this specific test or assessment. The test is sufficiently sensitive to brain damage and attention deficits.The TODA is available as a highly standardized computer test (for Windows computers), so every patient has exactly the same version.
According to how the test is developed, it MUST have a high potential in detecting attentional problems. An English translation will become available in 2011.The TODA is 9 minutes long, it will take about 11 minutes to administer and so one of the longer attention tests we have. 110 points), it seems that its differentiating power is limited.Overall, just as with the TMT I would use this SDMT as a very short screening test for attentional problems if there are no other more elaborate attention tests around. 13 minutes just the test itself takes; the whole test administration with instructions and practice takes at least 20 minutes (with neurological patients I assume it would take even more, probably up to 28 minutes). No other attention test has such a large norm group of different neurological patients (n=1019).
A further problem with the SDMT is that it is so much used that nearly everyone can get a copy of it and just practice with the test. My recommendation would be that the TMT can be used as a short screening instrument in case no other tests for concentration are available. Only when more studies are done in clinical (neurological) patient groups, perhaps coupled with the TOSSA, data could show that the IVA is one of the attention tests to be used in neuropsychology.
Especially this last profile is interesting because especially with attention tests patients can very easily show suboptimal levels of effort and it is hard to differentiate such levels from extreme - out of the normal (even for brain injuries) - performances. The problem is that the other attention tests used in the study were not comparable continuous performance tests except for the new attention test TODA (Test of Divided Attention).
When sufficiently popular the prices will go down to ensure worldwide use and distribution.The TOSSA has shown high sensitivity and specificity in several pilot studies and can detect more easily concentration problems than other tests.
