Partial Representations of Scenes in Change Blindness: In the Eyes and in the Hands


Change blindness is a person’s inability to notice changes in a visual scene that seem obvious when pointed out. Recent experiments using eye tracking techniques have suggested that even though participants do not detect a change they fixate on the changing area more. Two studies test whether this finding is present across different change blindness paradigms and whether it is detectable after fixation. In the first study we compare behavior in flicker and gradual change paradigms. Results reveal that across paradigms participants do spend more time on the changing area yet do not detect the change. In the second study we test whether we can capture the traces of change blindness in mouse movement. Findings indicate that accuracy has more of an impact on mouse movement than presence of change.
