(A) 75% perceptual thresholds in the LD experiment of the first 8 participants (light orange) and of the further 8 participants for the replication of the results (dark orange). Black error bars plot the 95% confidence intervals. (B) 75% perceptual thresholds in VD (blue) and DT (green) experiments plotted as a function of 75% perceptual thresholds in LD experiment. The red dashed line shows equal values. (C) 75% perceptual thresholds in the AD experiment of 10 participants. Black error bars plot the 95% confidence intervals. The horizontal line plots the average threshold across participants.
