DETECTABILITY AND PERCEIVED DEGREE OF FACIAL HAPPINESS, ANGRINESS, AND EMOTION: THE ROLE OF THE PARTICULAR STIMULI
AbstractThe purpose was to elucidate further Pixtonâ€™s (2007, 2008) results. Thirty participants (8men, 22 women) viewed pictures of facial expressions (Tottenham et al., 2009) with threepresentation times (12.50, 18.75, 25.00 ms) and completed a detection (Part 1) and a rating(Part 2) task. In Part 1, participants answered â€œyesâ€ if they thought the face was emotionaland â€œnoâ€ if the face was not emotional. In Part 2, they rated each face stimulus on each ofthree scales (angriness, happiness, and emotionality). â€œNeutralâ€ faces were not rated as quiteneutral on the different scales. The dâ€² values were higher for happy than for angry faces.When standardizing the dâ€² values for each face type through division by its Euclidean distancefrom the â€œneutralâ€ face in the scaled emotion space, a male superiority effect appeared forboth happy and angry faces. Together with Pixtonsâ€™ results, this suggests that wheninvestigating the detectability of emotions, account must be taken of the particular stimuliused.
