Priming of supernatural agent concepts and agency detection

In evolutionary approaches to religion it is argued that belief in supernatural agents is strongly related to a perceptual bias to over-detect the presence of agents in the environment. We report five experiments that investigate whether processing concepts about supernatural agents facilitates agency detection. Participants were presented with point-light stimuli representing unscrambled or scrambled biological motion, or with pictures of unscrambled or scrambled faces, embedded in a noise mask. Participants were required to indicate for each stimulus whether it represented a human agent or not. Each trial was preceded by a supernatural agent prime, a human agent prime, or an animal prime. Our results showed that primes referring to humans facilitated the detection of agency. More importantly, however, results did not reveal a general effect of supernatural priming on agency detection. In three experiments, a moderating effect of religiosity was observed: supernatural agent primes had a differential effe...
