Summary saccade parameters for the three participant groups.

CC: Participants born and educated in China, studying in the UK (N = 70); BC: Chinese ethnic background, born in the UK (or moved as infants), educated in the UK (N = 45); WB: Caucasian (white British) comparison group (N = 70). Intersubject mean median (±SD) saccade latency, intersubject mean amplitude, and mean percentage of express saccades (%ES) is shown for gap and overlap conditions. The final column shows the IS mean gap effect (Overlap-Gap latency).
