FIG. 3.

Barplots of mean listener sensitivity (d ′ scale) ± 1 standard error of the mean for the interactions between trial type and attentional configuration. 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. The bracket corresponds to the model coefficient foil:semantic:adjacent, which indicates increased responses to foils (i.e., more false alarms and thus lower d ′) in phonetic divided attention trials with spatially non-adjacent attended streams (light gray plain bar lower than light gray hatched bar, but dark gray bars equal).
