Behavioural responses and model predictions.

Mean behavioural responses (dark bars) and model predictions (light bars) to visual-only (top row), auditory-only (left column) and audiovisual stimuli (central panels) for 16 participants. Error bars represent the standard error of the mean. Visual stimuli are divided into G (left compartment) and B (right compartment) and are presented with descending SNR (left: high SNR to right: low SNR within each compartment. Auditory stimuli are divided into B (top compartment) and G (bottom compartment) and are presented with descending SNR (top: high SNR to bottom: low SNR within each compartment). Each audiovisual stimulus is a combination of the auditory and aisual stimulus on the corresponding row and column, presented either in synchrony (blue bars) or out of sync (red bars). The model predictions displayed are cross-validation predictions from the Reduced Joint Prior model.
