Knowledge-Based Patterns of Remembering: Eye Movement Scanpaths Reflect Domain Experience

How does knowledge of a domain influence the way in which we inspect artefacts from within that domain? Eye fixation scanpaths were recorded as trained individuals looked at images from within their own domain or from another domain. Sequences of fixations indicated differences in the inspection patterns of the two groups, with knowledge reflected in lower reliance of lowlevel visual features. Scanpaths were observed during first and second viewings of pictures and found to be reliably similar, and this relationship held in a second experiment when the second viewing was performed one week later. Eye fixation scanpaths indicate the viewer?s knowledge of the domain of study.
