Table 1. Summary saccade parameters for the three participant groups.

Group	Gap			Overlap
	Latency (ms)	Amplitude (deg)	%ES	Latency (ms)	Amplitude (deg)	%ES	Gap Effect (ms)
CC	120±16	11.0±2.3	50±21	165±25	10.8±2.2	20±16	45±17
BC	117±14	10.6±1.2	52±18	165±26	10.5±1.7	18±16	47±19
WB	127±19	10.7±1.9	42±23	189±31	10.7±1.9	13±12	61±27

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).
