From: Confidence is higher in touch than in vision in cases of perceptual ambiguity
Objective and subjective accuracy. (a) Confidence vs. objective accuracy. (b) Confidence vs subjective accuracy. (c) Subjective accuracy collapsed into low and high levels. (d) Confidence ratings on individual trials, relative to that observer’s mean rating, as a function of distance from PSE. Confidence depended on modality, and the distance of the vertical bars’ length from PSE. Confidence is greater in touch for bars close to PSE, and greater in vision for bars far from PSE. Thin lines show samples from the posterior distribution of Gaussian processes describing the relationship between confidence and bar length. Thick lines show maximum a posteriori functions. Confidence is greater in touch than vision for stimuli close to PSE, but greater in vision otherwise. (e) Confidence ratings individual trials as a function of normalised distance from PSE - distance from PSE, multiplied by that participant’s psychophysical slope in that modality. Confidence is higher in touch than vision for stimuli within 3 standard deviations of PSE.
