Implicit causal inference.

<p>Results of the implicit causal inference (left/right inertial discrimination) task. <b>A</b>: Vestibular bias as a function of co-presented visual heading direction <i>s</i>_vis, at different levels of visual reliability. Bars are ±1 SEM across subjects. The inset shows a cartoon of how the vestibular bias is computed as minus the point of subjective equality of the psychometric curves of left/right responses (L/R PSE) for vestibular stimuli <i>s</i>_vest, for a representative subject and for a fixed value of <i>s</i>_vis. The vestibular bias is strongly modulated by <i>s</i>_vis and its reliability. <b>B</b>: Protected exceedance probability and estimated posterior frequency (mean ± SD) of distinct model components for each model factor. Each factor also displays the Bayesian omnibus risk (BOR). <b>C</b>: Model fits of several models of interests (see text for details). Shaded areas are ±1 SEM of model predictions across subjects. Numbers on top right of each panel report the absolute goodness of fit.
