From: Visual motion information modulates tactile roughness perception
Results for tactile roughness judgments in Experiments 1–4 (a–d). The left-hand panels show the mean roughness evaluation of each comparison stimulus relative to the standard stimulus. The horizontal axis denotes the particle diameter, such that larger values indicate higher physical roughness. The right-hand panels show the perceived roughness magnitudes averaged across the comparison stimuli. The small dots represent each participant’s data. The error bars denote the standard errors of the mean (N = 15). Asterisks indicate significant differences in the fixed effect with GLMM (p < 0.05).
