The authors studied four patients with spatial neglect, using a task in which lines contain an off-centered bisection mark and a task in which the right and left segments of these bisected lines are presented independently and sequentially. In the prebisected line task, subjects reported the position of the bisection. In the segments task, subjects compared the length of the segments. Accuracy was greater with the sequential presentation of line segments, suggesting that an extinction-like phenomenon plays a role in line bisection bias.
