Abstract:Crosstalk between conflicting response codes contributes to interference in dual-tasking, an effect exacerbated in advanced age. Here, we investigated (1) brain activity correlates of such response-code conflicts, (2) activity modulations by individual dual-task performance and related cognitive abilities, (3) task-modulated connectivity within the task network, and (4) age-related differences in all these aspects. Young and older adults underwent fMRI while responding to the pitch of tones through spatially m… Show more
