FIGURE 27.4

Summary of mean sensitivity (d’) values (panel a) and criterion (c) (panel b) for unimodal auditory, unimodal visual, bimodal auditory, and bimodal visual targets in Koppen et al.’s (2009) signal detection study of the Colavita visual dominance effect. Error bars indicate the standard errors of means. The results show that although the simultaneous presentation of auditory and visual stimuli resulted in a reduction of auditory sensitivity (when compared to performance in unimodal auditory target trials), no such effect was reported for visual targets. The results also show highlight the fact presentation of a bimodal audiovisual target resulted in a significant reduction in the criteria (c) for responding, and that this effect was significantly larger for visual targets than for auditory targets.
