Abstract

Cognitive control is a domain-general process essential for independent living and is particularly vulnerable to age-related decline. This study aimed to investigate the effects of cognitive control training on functional connectivity during both resting-state and cognitive control task performance, using data from Kim, Lee, and Chey (2017), which examined the impact of cognitive control training on cognitive function and brain activation in healthy older adults. Data from 25 older adults aged 64–77 years (13 in the training group and 12 in the comparison group) were analyzed. The training group completed 24 sessions of cognitive control training over eight weeks, while both groups underwent neuropsychological assessments and fMRI scans before and after the training period. Compared to the comparison group, the training group demonstrated decreased connectivity within the sensorimotor network during the resting state and increased connectivity within the default mode network during the cognitive control task. Moreover, these changes in functional connectivity were associated with improvements in cognitive control performance. The implications of these findings are discussed, along with suggestions for future studies.
