Notes:

All values represented as mean(SE) collapsed for speed (slow, SS, fast)

significant difference, between groups (pain/no pain) (p<.016)

approaching significance between groups (pain/no pain) (p<0.05)

Mean= traditional “mean” performance variable

SD= within subject standard deviation (σ)

CV= Coefficient of Variation expressed as % (σ/μ * 100)
