the anti-saccade task). Thus, participants with AD are expected to show a greater number of eye movements towards salient, task-unrelated stimuli. This should also be reflected in the MCI group but will be mediated by performance on cognitive assessments. Results: All the saccades of different groups of participants collected during the video watching tasks were filtered and then generated density maps based on their direction and amplitude. Each map was then condensed into two values using a feature extraction analysis using kernel principal component analysis (KPCA). Conclusions:Preliminary findings suggest that the distribution of the saccades for MCI and AD groups are different than old and younger groups.
