Composite bias score defined and compared to patients’ scores. Panel a. Overlaid plots of controls (N=81) mean occluded minus whole difference score (y-axis) for each face for trust (blue) and for threat (red) show that faces that were not trusted in the occluded condition also tended to be found threatening relative to the whole-face condition. This consistent bias contributed to the formation of a composite bias score (black; 95% CI in gray) defined by adding the trust and reversed threat bias scores for each face. Face stimuli (x-axis) rank-ordered according to composite bias score. Faces with a negative bias score tended to be avoided in the occluded relative to whole condition (or, conversely, approached more in the whole face condition), while faces with a positive bias score tended to be approached more in the occluded face condition. Panels b–d. Controls’ mean composite bias score (black; 95% CI in gray), with individual patients’ scores overlaid in teal demonstrate a trend for patient bias scores to exceed controls’ scores.
