However, there was a marginally significant main effect of task [ F (1,16) = 4.46, p = 0.051, η p 2 = 0.218], which showed that under both action conditions, the CNV amplitude was more negative for the congruent task than for the incongruent task, suggesting that because of the age-related deficit, other cognitive processes might be involved.
