Fig. 4. Effect of dominant limb acute deafferentation. (A and B ) Response times (A ) and corresponding proportion of correct responses (B ) reported by subjects after upper-limb anesthesia of their dominant (black circles ) or nondominant (light gray circles ) limbs. The averages for the six natural and six unnatural orientations are presented for each view. Error bars represent SD. ANOVA main effect of laterality (dominant/nondominant limb) was significantly different for both proportions of correct responses (F1,18= 4.6, P < 0.01) and responses times (F1,18= 10.45, P < 0.005).
