Summary of peak times (mean ± SE)

	PIVC	VIP	MSTd
Single-peaked	0.98 ± 0.03	1.07 ± 0.03	1.08 ± 0.02
Double-peaked
First peak	0.82 ± 0.02	0.83 ± 0.02	1.03 ± 0.03
Second peak	1.25 ± 0.02	1.32 ± 0.03	1.50 ± 0.03

Peak time values are expressed relative to stimulus onset (i.e., a peak time of 1 s occurs at the time of peak stimulus velocity).
