This erratum concerns Fig. 8 of the original article, which contained horizontal error bars for some psychometric functions when there should not have been any horizontal error bars. The corrected Fig. 8 is provided below. The caption has not changed. I apologize for my error.
FIG. 8.
Top row (A1–A3): Psychometric functions for the co-located cases for each of the three Conditions [Condition TsMs left (A1), Condition TsMn middle (A2), and Condition TfsMfs right (A3)], and for each number of maskers (Co-2, Co-4, and Co-6). Error bars are ±1 standard deviation (see Fig. 3). Bottom row (B1–B3): Psychometric functions for the co-located cases for each number of maskers [Co-2 left (B1), Co-4 middle (B2), Co-6 right (B3)], and for each of the three Conditions (Condition TsMs, Condition TsMn, and Condition TfsMfs). Error bars are ±1 standard deviation (see Fig. 3).
