Psychophysics Of Perceiving Eye-Gaze And Head Direction With Peripheral Vision: Implications For The Dynamics Of Eye-Gaze Behavior, Jack M. Loomis, Jonathan W. Kelly, Matthias Pusch, Jeremy N. Bailenson, Andrew C. Beall

Jonathan W. Kelly

Two psychophysical experiments are reported, one dealing with the visual perception of the head orientation of another person (the `looker') and the other dealing with the percep- tion of the looker's direction of eye gaze. The participant viewed the looker with different retinal eccentricities, ranging from foveal to far-peripheral viewing. On average, judgments of head orientation were reliable even out to the extremes of peripheral vision (90 8 eccentricity), with better performance at the extremes when the participant was able to view the looker changing head orientation from one trial to the next. In sharp contrast, judgments of eye-gaze direction …
