FIG. 2.

Summary response data collapsed across angle and pitch separation when attending location (A) and pitch (B). Each column is one of the four possible conditions (in the same order as they appear in Fig. 1A), and each color-coded portion of the bar corresponds to a specific response type. There were four response types: correct, in which both digits were correctly reported; wrong-feature, in which the subject reported the digits that would have been correct under the alternate attention instructions; confusion, which is any error that is not a wrong-feature error, but no digits which were not present in the stimulus were reported; and guessing, in which the subject reported at least one number that was not present in the stimulus.
