Graphical summary of the results. On each panel, the encircled eye indicates the DE and the connected arrow its preferential relationship with its ipsilateral hemisphere (Shima et al., 2010; Chaumillon et al., 2014). Concerning the IHTT over the posterior sites (P-sites), the present experiment revealed that in right-handers, the asymmetry in IHTT strictly depends on the eye dominance. Indeed, right-handers with a left DE (A) show faster interhemispheric transfer from left to right than from right to left whereas right-handers with a right DE (B) show the opposite pattern. In left-handers, individuals with a left DE (C) show no asymmetry whereas individuals with a right DE (D) show a faster interhemispheric transfer from right to left than from left to right. Concerning the IHTT over central sites (C-sites), right-handers show no difference between the two interhemispheric transfer directions. On the contrary, left-handers with a left DE show faster IHTT from left to right whereas left-handers with a right DE show no difference between the two interhemispheric transfer directions.
