(A) Example horizontal eye movement time series for two adults, A1 and A2, resulting in a strong inter-subject correlation (ISC). (B) Averaging ISCs from each pair of observers within an age group (each line represents an ISC) yielded a measure of within-group correlation (ISCw). Thick lines highlight ISCs calculated for one observer, A1, paired with observers A2–A6. Dashed circles highlight the observers used in panel (A), A1 and A2. (C) Example horizontal ISC between a 6-month-old (B1) and an adult (A1) resulting in a weak correlation. (D) Averaging ISCs from pairs of observers in two different age groups yielded a measure of between-group correlation. Thick lines illustrate ISCs calculated for one observer, B1, paired with observers A1–A6 of a different age group. Dashed circles highlight the observers used in panel (C), B1 and A1.
