Mean ERP amplitude 50–100 ms post-screen-touch at electrode FCz, binned according to trials in which contact with screen corresponded to a hit, a small miss, a medium miss, and a large miss.

Error size	Mean	SD	95% CI
Hit	3.36	2.06	[2.39, 4.33]
Small error	2.95	2.68	[1.69, 4.21]
Medium error	1.20	3.12	[-0.25, 2.67]
Large error	0.98	4.52	[-1.13, 3.10]

SD, standard deviation; 95% CI [x, x], upper and lower limit of 95% confidence interval.
