Abstract
In a visual search task, we compared electroencephalography (EEG) and eye-tracking features following saccades on targets that were subsequently reported (hits) and targets that were not (misses). Previous work showed similar saccade-related potentials (SRPs) between missed targets and nontargets, but in that work targets were probably not identified after fixation. Here, we focused on targets that were missed due to memory encoding failures. SRPs indicated similar initial processing between hit and missed targets, consistent with missed targets being less well stored rather than being less well identified. Results from eye variables were consistent with targets being missed when fixation duration is short and when momentary workload is high (large pupil size). This work suggests complementary contributions of eye and EEG measures in potential applications to support search and detect tasks.
