F. Gerhards, DECODING OF FACIALLY EXPRESSED EMOTIONS IN PATIENTS WITH PSYCHOSOMATIC GASTROINTESTINAL DISORDERS, Behavior modification, 22(2), 1998, pp. 184-191
The hypothesis that individuals with psychosomatic conditions are lack
ing in empathy was tested by investigating decoding abilities of facia
lly expressed emotions. Fourteen subjects with psychosomatic gastroint
estinal disorders and 14 matched controls participated. Slides of one
male and one female. model's facial expressions of anger, disgust, fea
r, happiness, sadness, and surprise, and a neutral face, were presente
d to subjects, with exposure durations of 1/60, 1/15 and 4 seconds. Su
bjects had to decide whether the face presented was neutral or express
ed one of the basic emotions. There were no significant group differen
ces in decoding neutral expressions, but significant differences resul
ted in decoding emotional expressions. This was mainly due to the sign
ificantly poorer performance of the psychosomatic group in decoding di
sgust Subjects' responding was found to be reliable. The findings show
that at least certain subgroups of psychosomatic patients tend to mis
interpret another person's facial expressions that signal unpleasantne
ss or interpersonal conflict.
