Experiment 1 results. (a) Participants’ perceived stimulus azimuth plotted against actual stimulus azimuth, following 1 minute of adaptation to audio-visual pairs spatially offset by −20° (audio left of visual), 0°, or 20° (audio right of visual). Data were concatenated across participants and entered into a series of mixed-effects linear regression analyses: thick black lines indicate average fixed-effects fits, thin grey lines indicate per-participant mixed-effects fits. Bar plots show (b) spatial bias and (c) spatial gain parameters, given by the fixed-effects intercept and slope coefficients respectively. Error bars indicate standard errors of the regression coefficients. Annotations indicate the results of pairwise t-tests contrasting the coefficients between adaptation offset conditions (***p < 0.001).
