Abstract
Abstract The Simon effect is typically larger for older people than for young adults, maybe due to age-related decline in inhibitory capabilities. 32 right-handed aged people (5 male, 27 female; mean of 67,1 years ± 5,5) participated in this study. In screening were used the Mini-Mental State Examination and the Center for Epidemiological Study Depression Scale. Then, half of the participants practiced the spatial incompatibility task before the Simon task and the other group was only tested on the Simon task. The analysis of variance considering practice (incompatible, no-practice group) and correspondence (corresponding, non-corresponding) revealed a two-way interaction (F = 7.07; p = 0.012; ?p2 = 0.191) showing that the Simon effect was eliminated in the incompatible practice group, but remained intact in the group with no previous practice. These results indicated that cognitive processes required to the transfer of learning are preserved in elderly, being potentially useful to influence spatial inhibitory capabilities.
