FIG. 5.

Barplots of mean listener sensitivity (d ′ scale) ± 1 standard error of the mean for the main effects size, congruence, and adjacency in experiment 2. Background shading indicates chance and ceiling performance levels. Brackets indicate the presence of corresponding coefficients in the statistical model that are significantly different from zero; * indicates p < 0.05, ** indicates p < 0.01, *** indicates p < 0.001. (a) Main effect of category size (three versus six words per category). The difference corresponds to the significant model coefficients target:three (positive, indicating better target detection in trials with 3-word categories) and foil:three (positive, indicating higher tendency in the 3-word condition to incorrectly identify of foil items as targets). (b) Main effect of attended category congruence. None of the relevant model coefficients (target:congruent and foil:congruent) are statistically significantly different from zero. (c) Main effect of spatial adjacency of the attended streams. The difference corresponds to the significant model coefficient foil:adjacent, indicating higher tendency to incorrectly identify foil items as targets when the attended streams are spatially separated.
