Paced Auditory Serial Addition Test (PASAT) is a neuropsychological test used to assess capacity and rate of information processing and sustained and divided attention.

The subjects are given in the version used as part of the Multiple Sclerosis Functional Composite a number every 3 seconds and are asked to add the number they just heard with the number they heard before.

Neuropsychological tests are typically administered to a single person working with an examiner in a quiet office environment, free from distractions. As such, it can be argued that neuropsychological tests at times offer an estimate of a person's peak level of cognitive performance.
