The relationship betweeen P300 latency and digit span reported by Polich, Howard, and Starr (1983) is re‐examined. Evidence is presented which shows that these authors' use of partial correlation to correct for age differences in their sample of subjects is erroneous because the assumption of linear regression is clearly not satisfied. This finding seriously questions Polich et al.'s conclusion that P300 latency and digit span covary irrespective of any relationship of the variables to age.
