Fifty-seven cognitively intact geriatric medical patients were given the Boston Naming Test in order to provide preliminary normative data on a group of less highly educated older adults than was used in previous studies (e.g., VanGorp, Satz, Evans-Kiersch, & Henry 1986). Analysis of variance revealed significant main effects for age and ethnicity that accounted for over 20% of the Boston Naming Test variance. In addition, the preliminary data in the present study varied widely from previous publications, especially among the African-American subjects.
