Recognizing facial expressions is crucial for the success of social interactions, and the visual processes underlying this ability have been the subject of many studies in the field of face perception. Nevertheless, the stimuli used in the majority of these studies consist of facial expressions that were produced on request rather than spontaneously induced. In the present study, we directly compared the visual strategies underlying the recognition of posed and spontaneous expressions of happiness, disgust, surprise, and sadness. We used the Bubbles method with pictures of the same individuals spontaneously expressing an emotion or posing with an expression on request. Two key findings were obtained: Visual strategies were less systematic with spontaneous than with posed expressions, suggesting a higher heterogeneity in the useful facial cues across identities; and with spontaneous expressions, the relative reliance on the mouth and eyes areas was more evenly distributed, contrasting with the higher reliance on the mouth compared to the eyes area observed with posed expressions.
