Parametric bias visualization. Overlaid plots of controls’ (N=81) mean composite bias score (y-axis, black; 95% CI in gray) and patients’ (N=3) mean composite bias score (red circles; smoothed with a 10 face moving average, with a step size of one face). The patients all tended to have a higher approach bias than controls, meaning they tended to approach occluded faces more than controls. Face stimuli (x-axis) rank-ordered according to mean control composite bias score. Synthetic patient ratings (light-blue squares, also smoothed with a 10 face moving average), indicate patient bias scores given actual whole-face ratings and chance occluded-face ratings; these scores test the hypothesis that the deviation of patients’ bias scores from controls’ scores was driven by abnormal occluded-face ratings; since chance occluded ratings did not exceed controls’ bias scores, the effect was driven by the patients’ tendency to approach occluded faces more than whole faces.
