Model fit. A sample participant’s model fitting results. (A) Gaze data, with gaze Time Headway (TH) along the ordinate and Time into Trial along the abscissa. Gaze fixation data are shaded according to the probabilities of belonging to Guiding Fixations (GF; blue), Entry Fixations (EF; red) or Noise (Grey) clusters. (B) The regression lines and standard deviations of each model, from which a weighted sample is taken. (C) Smoothed cluster weights across the track. (D) Raw gaze TH density (solid black) overlaid with the fitted gaze TH density (dotted black). (E) The fitted gaze TH density decomposed into mixtures of GF (blue) and EF (red). Vertical dotted lines represent the estimated means.
