WebIn this case, an arrangement is needed to switch from the attentional concentration of the task fixation cue to the forthcoming stimulus. Therefore, hippocampal activity preceding stimulus was enhanced on those stimuli where processes arranged for the presentation of the fixation cue and resulted in a reasonably optimal preparative status. WebIn addition, we asked whether any influences of WMC, mind wandering, or intraindividual RT variation on antisaccade are moderated by (a) the temporal gap between fixation and the flashing location cue, and (b) whether targets switch sides on consecutive trials.
