Abstract: The judgement of healthy subject rating the emotional expressions of a set of schematic drawn faces is validated (study 1) to examine the relationship between mood (depressed/elated) and judgement of emotional expressions of these faces (study 2). Study 1: 30 healthy subjects judged 12 faces with respect to the emotions they express (fear, happiness, anger, sadness, disgust, surprise, rejection and invitation). It was found that a particular face could reflect various emotions. All eigth emotions were reflected in the set of faces and the emotions were consensually judged. Moreover, gender differences in judgement could be established. Study 2: In a cross-over design, 24 healthy subjects judged the faces after listening to depressing or elating music. The faces were subdivided in six 'ambiguous' faces (i.e., expressing similar amounts of positive and negative emotions) and six 'clear' faces (i.e., faces showing a preponderance of positive or negative emotions). In addition, these two types of faces were distinguished with respect to the intensity of emotions they express. 11 subjects who showed substantial differences in experienced depression after listening to the music were selected for further analysis. It was found that, when feeling more depressed, the subjects perceived more rejection/sadness in ambiguous faces (displaying less intensive emotions) and less invitation/happiness in dear faces. In addition, subjects saw more fear in clear faces that express less intensive emotions. Hence, results show a depression-related negative bias in the perception of facial displays.
