Illustration of the experimental designs of Study 1. (a) Perceptual Categorization experiment. Observers were shown a face-body stimulus and were asked to indicate the facial expression by clicking on one of four buttons (buttons are not to size). (b) During adaptation observers were adapted to one of four face-body combinations: a disgusted face was shown in an angry – as illustrated here – or a disgusted body context; in the remaining conditions, the body contexts were shown with a blurred face so that no facial expression was discernable. Test trials (c) consisted of a top-up adaptation stimulus followed by a target facial expression (morph between disgusted to angry). All indicated timings include a sinusoidally modulated ramp into (100 ms) and out of the full image (100 ms). This was used to minimize retinal aftereffects.
