Results of Study 1. Facial expressions in this study always showed disgust. (a) Mean proportion of perceptual categorizations as disgusted or angry in response to a disgusted facial expression in a disgusted or angry body context. (b) Psychometric functions from one example observer to illustrate the results of the adaptation task. Dotted lines indicate PSEs, the size of the circles illustrates the number of trials for a given morph level. As can be seen, there is no difference between the baseline PSE and PSEs after adaptation to body contexts alone. Adaptation to a disgusted face generates aftereffects, as indicated by the difference of the respective PSEs to baseline. These aftereffects are independent of body context and consistent with adaptation to disgust. (c) Facial expression aftereffects plotted as the mean difference between the baseline PSE and PSEs after adaptation to face-body stimuli, for a disgusted facial expression with a disgusted or angry body (diamonds), and for the two body contexts without faces (circles). Error bars denote ±1 SEM in all plots.
