Understanding the Latent Structure of Interval Timing

Activity: Talk or presentation for an academic audienceOral presentation for an academic audience


One ongoing controversy in interval timing is whether subsecond and suprasecond timing rely on a single semi-uniform or multiple separate mechanisms. We conducted two online experiments (N=604) using exploratory factor analysis and structural equation modelling to differentiate distinct latent structures underlying duration reproduction patterns. Additionally, we compared the model outcomes with changepoint analysis models fitted to individual participants' data. Both experiments yielded evidence for a two-factor model comprising a general timing factor spanning the full interval range and a second factor capturing the regression to the mean of presented intervals (central tendency bias). Few changepoints were detected, supporting limited evidence of discontinuity between mechanisms, with detection predicted by factor scores. Our results highlight the role of central tendency effects in investigating changepoints and the continuity of timing systems. This study integrates factor analytic and computational modelling approaches, enhancing understanding of time perception and its measurement in a range of contexts.
