Arithmetic and Aging: Impact of Quantitative Knowledge and Processing Speed
Rozencwajg, Paulette; Schaeffer, Olivier; Lefebvre, Virginie
Learning and Individual Differences, v20 n5 p452-458 Oct 2010
The main objective of this study was to examine how quantitative knowledge ("Gq" in the CHC model) and processing speed ("Gs" in the CHC model) affect scores on the WAIS-III Arithmetic Subtest (Wechsler, 2000) with aging. Two age groups were compared: 30 young adults and 25 elderly adults. For both age groups, "Gq" was an important predictor of Arithmetic score variance (R[superscript 2] = 48% and R[superscript 2] = 45%, respectively). However, in line with Salthouse, the results showed that processing speed predicted Arithmetic scores only for the older adults, not for the younger ones (additional 9% of the variance for the elderly vs. 1% of the variance for the young adults). These results can clarify the ambiguous evolution of Arithmetic scores with aging: Arithmetic performance with aging seems to follow an intermediate path between "Gc" and "Gf." This suggests that both "Gq" and "Gs" have an impact on Arithmetic in aging. (Contains 3 tables and 6 figures.)
