| Abstract: | Previous studies on performance monitoring repeatedly found attenuated error-related negativities (Ne/ERN) in elderly, while findings for the correct-related negativity (Nc/CRN) are inconsistent. The present study aimed at clarifying inconsistent Nc/CRN results in elderly. Therefore, a refined design was employed to control for potential influences on the Nc/CRN, namely decision uncertainty and partial error processing. Further, we intended to study Nc/CRN variations with trial compatibility that were found in previous studies for younger but not for older adults. Results revealed increased Nc/CRN and decreased Ne/ERN amplitudes in older compared to younger adults. While the Ne/ERN was larger than the Nc/CRN in younger adults, both components were similar-sized in older adults. Further, a modulation of Nc/CRN amplitudes between compatible and incompatible trials was observed in younger adults, but was absent in older adults. Reduced differentiation of response-related negativities with response accuracy or stimulus compatibility in elderly suggests a reduced adaptation of associated processes to changing demands. Further, this might also point to different processes reflected by Nc/CRN and Ne/ERN and to reduced error-specific monitoring but increased general or strategic monitoring in elderly. |
