Evidence from eye movements. Computers in Human Behavior 26, no. 1: 110-117. January 2010.]])) has confirmed and attempted to explain the signaling effect using recorded eye movements data of the experiment participants. Some of the conclusions of this and similar studies concerning the signaling effect are: | ||
| + | |||
| + | * Signaling can guide attention to relevant information, which reduces cognitive resources normally assigned for search of information(([[http://www.odtu.edu.tr/~kursat/CHB_1184-preprint.pdf|Ozcelik, Erol, Ismahan Arslan-Ari, and Kursat Cagiltay. Why does signaling enhance multimedia learning? Evidence from eye movements. Computers in Human Behavior 26, no. 1: 110-117. January 2010.]])) | ||
| + | * Eye-tracking studies confirmed that signaling results in more attention devoted to relevant information(([[http://www.odtu.edu.tr/~kursat/CHB_1184-preprint.pdf|Ozcelik, Erol, Ismahan Arslan-Ari, and Kursat Cagiltay. Why does signaling enhance multimedia learning? Evidence from eye movements. Computers in Human Behavior 26, no. 1: 110-117. January 2010.]])) | ||

| + | * In cases when signaling is used, time for finding information is usually reduced, but duration of time spent watching/processing this information increases when compared to no signaling conditions | ||
