Fig 3. The phase/offset parameter (φ) of the PVD model for each of condition across subjects.

The average (combined) value is shown in the furthest right column marked with a C. For the HCGC conditions the average phase offset was near zero. In conditions where the trial blocks included multiple head and/or gaze positions (panels C-K) a T-test was used to determine if the values were significantly different across subjects and p-values are printed for each condition.
