In L condition both cost indexes (JI and TC) do not differ between arms and movement directions; on the contrary, significant differences can be observed for both JI and TC during high speed trials: anova tests showed a significant effect of “used arm” on TC in H condition (p = 0.0293), and a non-significant effect, but close to significance, on JI (p = 0.0572); moreover, both indexes showed a statistically significant effect of “movement direction” (p < 0.05 for JI and p < 0.01 for TC), while the effect of the interaction “used arm” x “movement direction” is not statistically significant.
