Dr Benjamin de Haas published a study in which he and Alexios Iakovidis measured the gaze behaviour of participants (as well as reanalysed some already published data collected by others) while they looked at photographs of real-world scenes and events. They found that people vary considerably but consistently in terms of which kinds of objects they look at (e.g. faces, touchable objects, etc). Since finishing his fellowship in the SamPenDu lab he has moved to Germany where he continued this work with Karl Gegenfurtner and collected a third data set to replicate the results he found in previously. Since gaze behaviour determines what visual information is foveated and processed at higher resolution, this variability in gaze behaviour could have important consequences on what information is prioritised and the functional organisation of the visual systems of different observers. Our present results already hint at that being the case at least as far as face recognition is concerned.
