The Effects of Age and Modality on Digit Span Performance.
Fisher, Terri D.; And Others
Previous studies of the effect of age and modality on digit span task performance have yielded inconsistent results. To eliminate some of the methodological difficulties in prior research, 18 college students and 18 older adults were given the digit span task by means of three different modalities: (1) visual successive; (2) visual simultaneous; and (3) controlled auditory. A memory drum and a cassette tape recorder were used. Three different sets of digit series pairs, ranging in length from 3 to 12, were randomly generated for use in all three modalities. Results indicated a significant main effect of modality, with the visual simultaneous condition yielding the highest scores. A significant age by modality interaction revealed that age differences were significant for the visual successive and the auditory conditions, but not for the visual simultaneous condition. The findings suggest that much of the previous confusion may be due to an inconsistent methodology. (Author/JAC)
