Stress-related deficits of older adults ’ spatial working memory: An EEG investigation of occipital alpha and frontal-midline theta activity

This study paired electrophysiological with behavioral measures to explore how cumulative stress affects attentional and maintenance processes underpinning working memory retention. We collected electroencephalographic (EEG) recordings from 60 individuals (30 older, 30 younger) reporting high or low levels of cumulative stress during the performance of a spatial Sternberg task. We measured mid-occiptial alpha (8 – 12 Hz) and frontal-midline theta (4 – 6 Hz) as indicators of attentional and maintenance processes.
