Individual gaze predicts individual scene descriptions

Abstract

Abstract Do different people looking at the same scene perceive individual versions of what’s in front of them? If perception is individual, which mechanisms mediate our particular view of the world? Recent findings have shown systematic observer differences in gaze, but it is unclear whether individual fixation biases translate to divergent impressions of the same scene. Here, we find systematic differences in the scene descriptions individual observers provide for identical complex scenes. Crucially, observer differences in fixation patterns predicted pairwise differences in scene descriptions, particularly the use of nouns, even for out-of-sample images. Part of this could be explained by the individual tendency to fixate text and people predicting corresponding description references. Our results strongly suggest that subjective scene perception is shaped by individual gaze.
