Dr. Gary Kay stated under oath in court, The PASAT makes everyone cry. The PASAT would probably also be condemned by the California Department of Education in the same vein as timed math along with most math instructors. This article in the NIH from 2011 entitled Paced Auditory Serial Addition Test (PASAT): a very difficult test even for individuals with high intellectual capability does not speaking highly of the test at all https://pubmed.ncbi.nlm.nih.gov/21755126/ stating in the conclusion Even under ideal circumstances, PASAT is a very difficult test for the general population. It may not be ideal for neurologists to screen, assess and follow up patients with cognitive function in multiple sclerosis.

A question that should be asked, why is the FAA using a test for multiple sclerosis for ADHD testing, especially at the end of a 4+ hour testing session when the test taker is exhausted?
The use of tests beyond and/or completely outside their design intents was brought up the the NTSB Safety Summit on Dec 6, 2023 https://sites.google.com/site/no2cog/supporting-evidence/faa-admits-cog-tests-lack-data-are-subjective-are-used-beyond-intent?authuser=0
This shows the subjectively graded cognative tests have nothing to do with safety and are really about creating a cottage industry that holds pilots hostage for as much money can be squeezed out of them by dangling the hope with no guarantee of getting their medicals back. Far from it, these trapped pilots are subjectively graded as fails in order to keep them in hostage indefinitely. It's time to let the safest pilots have their unrestricted medicals back without any strings attached and to put these mental health quacks cottage industry of holding pilots hostage out of business.
