Abstract

Saccades are very rapid eye movements in between two phases of fixation, which offer a precise measure of behaviour for the direction of the spotlight of attention. The onset of global motion is known to attract our attention reflexively. We asked whether brief global motion stimuli are able to modify the execution of saccades. When participants performed visually guided saccades towards a target presented in front of a structured background, saccade latency was 174 ms on average and correctness of saccades was 100%. If the presentation of the target occurred at the same time as the onset of a brief global motion signal, then the saccade latency increased dramatically to 243 ms with a slight decrease in correctness to 89%. However, if the motion stimulus preceded the presentation of the target, then the latency decreased to 114 ms while the correctness dropped close to chance levels (62%).

TrendTerms

TrendTerms displays relevant terms of the abstract of this publication and related documents on a map. The terms and their relations were extracted from ZORA using word statistics. Their timelines are taken from ZORA as well. The bubble size of a term is proportional to the number of documents where the term occurs. Red, orange, yellow and green colors are used for terms that occur in the current document; red indicates high interlinkedness of a term with other terms, orange, yellow and green decreasing interlinkedness. Blue is used for terms that have a relation with the terms in this document, but occur in other documents.
You can navigate and zoom the map. Mouse-hovering a term displays its timeline, clicking it yields the associated documents.
