Figure 2. Results of the perception task.

Figure 2

Panel A: the proportion of “far” responses for the two stimuli conditions (visual vs. audio-visual; V and AV) as a function of expected response. The steeper slope in the AV condition indicates a larger illusion effect (bars represent 2 SEM around the mean after normalization to remove between-subject variability [32]). Panel B: post hoc analysis representing effect magnitude in the V and AV condition. Magnitude in the latter condition is bigger than in the former, nonetheless V condition magnitude is consistently smaller but statistically different from chance (see results section; bars represent 2 SEM around the mean after normalization to remove between-subject variability [32]). Panel C: regression analysis in the perceptual task, the effect magnitude in the AV condition is positively correlated with magnitude in the V condition.
