Alertness Training Increases Visual Processing Speed in Healthy Older Adults

In this study, we investigated whether alertness training in healthy older adults increases visual processing speed (VPS) and functional connectivity the cingulo-opercular network predicts gain. Using theory of attention, derived quantitative estimates VPS before after training. Study 1, 75 participated training, active-control or no ( n = 25 each). A significant Group × Session interaction indicated an increase alertness-training group but not control group, despite differing significantly between groups 2, 29 underwent resting-state MRI then Pretraining correlated with individual training-induced change VPS. conclusion, results indicate that improves provides a neural marker for predicting
