Causal inference regulates audiovisual spatial recalibration via its influence on audiovisual perception

Results for the unimodal spatial-discrimination task.
(A) Psychometric functions for representative participant S4. The probability of judging the test stimulus as to the right of the standard stimulus is plotted as a function of the distance between the two stimuli, with negative numbers indicating that the test stimulus was located to the left of the standard stimulus (presented straight ahead). V: Visual. A: Auditory. Filled circles: binned response proportions (bin size = 1.8°). The area of each filled circle is proportional to the number of trials within the bin. Solid curves: psychometric functions fit to the data. (B) Estimated just-noticeable difference (JND) of each visual stimulus type for S4. Solid line: auditory JND. Error bars and blue area: 95% bootstrapped confidence intervals. (C) Group mean JNDs (± SEM).
