Paced Auditory Serial Addition Test: adult norms and moderator variables.

This study examined the performance of a sample of 821 healthy job applicants on the Paced Auditory Serial Addition Test (PASAT). Subjects had previously passed basic academic skills tests and physical examinations and were deemed free of cognitive impairment and medical illness. They were also motivated to perform well on cognitive tests. Gender, ethnicity, and education were not significant moderator variables in our subjects. Age and IQ did significantly affect PASAT test results. Normative data are stratified by age and WAIS-R Full Scale IQ scores to be useful to those who administer the PASAT in clinical practice.
