Research Abstract |
We examined EEG synchrony during a visual search task in low and high target-distractor similarity conditions for young and elderly adults. For young adults, high gamma phase synchrony between prefrontal and parietal regions (indicating top-down control of attention) was greater in the high similarity condition, but low gamma phase synchrony (indicating bottom-up control of attention) was not different between conditions. For elderly adults, high gamma phase synchrony was greater in the low similarity condition, but low gamma phase synchrony was not different between conditions. These results indicate that attentional control style varies with aging.
