Two sub-groups with the opposite and stable preferential link between the visual vs. auditory modality and the dominant vs. non-dominant hand. (a) Correlations between the dominant-hand-for-vision index in the unimodal and the bimodal conditions for the whole group. (b) and (c) represented the unimodal and bimodal RT results for the visual preference group and the auditory preference group, respectively: left part of the Left panel, RTs in the unimodal trials are shown as a function of the sensory modality (visual vs. auditory) and the response hand (dominant vs. non-dominant hand); right part of the Left panel, RTs to the visual and auditory components of the bimodal trials are shown as a function of the response order (first vs. second response) and the response hand (dominant vs. non-dominant hand) for the VA and AV trials; Right panel, The simple effects for the significant sensory dominance*response order*response hand interaction in the bimodal condition. The dominant hand effect size is shown as a function of the sensory modality (visual vs. auditory) and the response order (first vs. second response). ***p < 0.001, **p < 0.01, *p < 0.05. The error bars show standard errors (SEs).
