Abstract [en]

The purpose was to elucidate further Pixton’s (2007, 2008) results. Thirty participants (8 men, 22 women) viewed pictures of facial expressions (Tottenham et al., 2009) with three presentation 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 “yes” if they thought the face was emotional and “no” if the face was not emotional. In Part 2, they rated each face stimulus on each of three scales (angriness, happiness, and emotionality). “Neutral” faces were not rated as quite neutral on the different scales. The d′ values were higher for happy than for angry faces. When standardizing the d′ values for each face type through division by its Euclidean distance from the “neutral” face in the scaled emotion space, a male superiority effect appeared for both happy and angry faces. Together with Pixtons’ results, this suggests that when investigating the detectability of emotions, account must be taken of the particular stimuli used.
