Causal inference regulates audiovisual spatial recalibration via its influence on audiovisual perception
Fig 3
Experimental procedure and results for the bimodal spatial-discrimination task.
(A) In each trial, a visual stimulus (high reliability) and an auditory stimulus (four possible auditory locations, ±2.5 and ±7.5° relative to straight-ahead) were presented in random order. Participants reported whether the visual stimulus was to the left or right of the auditory stimulus. Feedback was not provided. (B) Psychometric functions for participant S4. Probability of judging the visual to the right of the auditory stimulus is plotted as a function of visual stimulus location. Filled circles: binned response proportions (bin size = 3°). Curves: psychometric functions fitted separately for the four auditory stimulus locations (shades of blue). The area of each filled circle is proportional to the number of trials in each bin.
