Gaze duration is usually treated as a social judgement, but it is also a timing judgement. This poster presents a 2AFC duration-discrimination study designed to test whether individual differences in perceived gaze duration are best explained by one general timing source or by multiple duration-sensitive channels. Participants view dynamic ABABA gaze sequences and judge which direct-gaze interval was longer across five log-spaced duration levels. Rather than focusing only on mean accuracy, the study examines the covariance structure of performance across durations. A single scalar timing account predicts broad correlations across all levels, whereas a duration-channel account predicts stronger correlations between nearby durations and weaker correlations between distant durations. A Bayesian or contextual account may instead produce separable bias and precision components. The proposed analysis compares gaze-duration performance with an existing non-social Gabor timing benchmark to ask whether social timing shares the same latent architecture as low-level visual duration perception, or whether gaze duration recruits a partly distinct social-timing mechanism. This approach treats individual differences as diagnostically useful, rather than as noise, and uses them to adjudicate between competing models of social duration perception.
