DSS, visual double simultaneous stimulation; L, left; R, right; E, extinction; H, homonymous hemianopia. For line bisection, positive values indicate rightwards deviations, negative values leftwards deviations from the true center; *, left-sided neglect; †, right-sided neglect; #, special case (see Table 3 and Results section in the main text); U, unable to perform the task; ‡, the test was discontinued because of a severe impairment in target recognition.
