Sample stimuli from Eye Contact Detection Task.
Example of stimuli for one actor in the Eye Contact Detection Task. Gaze angles ranged from 30° (averted; signal strength = 0) to 0° (direct; signal strength = 1) in ten 10% increments. The task used face stimuli with both forward (top 2 panels) and deviated (bottom 2 panels) head orientations.
Fig 2.
Sample curve-fitting for Eye Contact Detection Task data.
A logistic function was fitted to each participant’s Eye Contact Detection Task data (separately for forward and deviated faces) in order to derive two measures of eye contact perception: self-referential tendency (threshold at 50% eye contact endorsement) and perceptual precision (slope at y = 50%).
Fig 3.
Eye contact endorsement rates across signal strengths.
Mean percentage of “Yes–looking at me” responses plotted against eye contact signal strength, calculated separately for forward/deviated faces. Error bars shown represent standard error.
