Audiovisual weight index (wAV): statistical significance.

Main effects and interactions for the audiovisual weight index (wAV) in the 2 (action intention: communicative; non-communicative) × 2 (response modality: auditory; visual) × 2 (spatial disparity: low; high) factorial design. P-values are based on two-tailed between-subjects permutation tests. Effect sizes [95% CI] correspond to the difference between the across-participants’ mean empirical effect and the mean of the non-parametric null distribution.
