Causal inference regulates audiovisual spatial recalibration via its influence on audiovisual perception
Fig 4
Modality-specific biases in spatial perception.
(A) Point of subjective equality (PSE) as a function of the location of the auditory stimulus. Dashed grey line: identity line; solid line: linear regression line; horizontal dashed lines: visual stimulus locations perceived as co-located with the four auditory standard locations based on the regression. (B) Estimated constant, location-independent (y-axis; regression intercept) and proportional, location-dependent (x-axis; regression slope) shift of visual relative to auditory stimulus location. The proportional and constant shifts equal the slope and intercept of the linear regression line through the PSEs (see panel A). Error bars: 95% bootstrapped confidence intervals. Vertical and horizontal dashed lines correspond to the absence of proportional and constant shifts, respectively.
