Recent studies showed that stimuli are evaluated more favourably when they are perceived to capture others' attention, an effect coined "mimetic desire". The aim of the present research was to examine the combined role of Need for Cognition and target's facial trustworthiness in this effect. Participants saw movie excerpts of trustworthy and untrustworthy 3D faces (Oosterhof & Todorov, 2008) turning their attention towards one art painting and away from another art painting. Results showed that looked-at paintings were preferred to looked-away paintings when associated with a trustworthy face. However, the reversed finding was observed for paintings associated with untrustworthy faces. The latter interaction was in turn moderated by participant's Need for Cognition, with a larger reversal effect for participants scoring lower on the NFC scale. Theoretical implications of these findings are discussed. (Contains 2 figures.)
