Extended norms for the paced auditory serial addition task

Abstract The Paced Auditory Serial Addition Task (PASAT) and an abbreviated version of the WAIS-R were administered to 143 normal individuals, including 62 persons aged 18 to 27 (58% female), 40 aged 33 to 50 (50% female), and 41 aged 60 to 75 (51% female). PASAT means and standard deviations are presented. Analysis of variance results revealed significant age effects on PASAT performance, with the 60-to 75-year age group scoring significantly lower than the two younger age groups on all four PASAT series. No significant gender effect was found. Small but statistically significant correlations were found between PASAT performance and estimated IQ.
