Figure 2.

When the task involves differences in orientation as well as location, strong attention impairs subjects' ability to detect large orientation changes. A, Proportion correct as a function of normalized orientation change sorted by attention axis position as in Figure 1B, for recording sessions in which the orientation of the two stimuli differed by <45° (28/49 recording sessions). B, Proportion correct as a function of position on the attention axis for the largest and smallest orientation change bins. Conventions as in Figure 1C. C, D, Same as A and B for recording sessions in which the orientation of the two stimuli differed by >45° (21/49 recording sessions).
