Quadrantic deficits and target orientation. The dotted line indicates chance level performance. (a) Performance as a function of global orientation. (b) Performance as a function of orientation relative to radial lines extending from fixation. The shaded region highlights the points at which the two pinwheels were oriented tangentially, as in experiment 1. Dashed lines indicate the two conditions in which the targets were oriented about the horizontal and vertical meridians.
