Eye movements in extended tasks: Analyses of ambient/focal attention with coefficient K

Publikation: Beitrag in FachzeitschriftKonferenzartikelBeigetragenBegutachtung


Patterns of scene exploration can be characterized by two modes of processing: an ambient mode, serving global spatial orientation in the visual environment, followed by a focal mode, facilitating a more elaborated and object-centered analysis. Previous studies suggest that shifts in these processing modes can also be identified in relation to changes in dynamic environments based on eye movement parameters. For the analysis of these changes in eye movement behavior, the coefficient K has been suggested. Here, we used a multi-step task, in which participants needed to perform a series of sub-tasks, to investigate whether shifts in ambient/focal attention can also be identified in complex task solving. While differences in eye movements and in the coefficient K were observed when switching between sub-tasks, the overall temporal dynamics in visual attention remained stable.
