Right-hemisphere injuries often produce contralesional hemispatial neglect (CN). In contrast to CN, however, some patients with right-hemisphere damage show so-called ipsilesional neglect (IN). Previous studies found that patients tend to show IN on line bisection tasks, but CN on other tasks, such as target cancellation. To learn why these two tasks induce different spatial biases in patients with right-hemisphere injury, performance on conventional line bisection (i.e., solid line) was compared with that on two novel bisection tasks involving horizontally aligned strings of characters. The subjects' task was to mark a target character that was at or closest to the true midpoint of the simulated line. Four of the five patients studied showed a dissociation in which IN occurred with solid lines, while CN was observed with character lines. In addition, two patients assessed with an antisaccade paradigm showed a “visual grasp” for leftward stimuli. These results suggest that neglect on line bisection may reflect two opposing forces: an approach behavior or “visual grasp” toward the left hemispace, and an attentional bias toward the right hemispace.
