In this paper we argue that sensory exploitation, a model from sexual selection theory, deserves more attention in evolutionary thinking about art than it has up until now. We base our argument on the observation that in the past sensory exploitation may have been underestimated in sexual selection theory but that it is now winning field. Likewise, we expect sensory exploitation can play a more substantial role in modeling the evolution of art behavior. Darwin's theory of sexual selection provides a (...) mechanistic basis to explain the evolution of male display traits. This mechanistic approach has proven useful to developing hypotheses about the evolution of human art. Both Boyd and Richerson (1985) and Miller (1998, 1999, 2000, 2001) have applied an indirect-benefit model from sexual selection to the evolution of art behavior. We argue that the mechanistic possibilities sensory exploitation has to offer as a model have remained underexplored so far, so we propose a concept based upon it. From the sensory exploitation perspective it follows that exaptive exploitation of psychosensory biases is a primary force in the evolution of art production (notice that the use of a model from sexual selection does not imply art evolved as a sexual display - we only use it for its mechanism) and that the indirect-benefit model only provides secondary forces. Thus, sensory exploitation may operate alone under some conditions but usually secondary processes as a result of indirect benefits are expected to kick in. The concept of sensory exploitation will need to play a central role in articulating all of the existing hypotheses about art. (shrink)

In this paper we present two compatible hypotheses to explain interest in celebrity gossip. The Learning Hypothesis explains interest in celebrity gossip as a by-product of an evolved mechanism useful for acquiring fitness-relevant survival information. The Parasocial Hypothesis sees celebrity gossip as a diversion of this mechanism, which leads individuals to misperceive celebrities as people who are part of their social network. Using two preliminary studies, we tested our predictions. In a survey with 838 respondents and in-depth interviews with 103 (...) individuals, we investigated how interest in celebrity gossip was related to several dimensions of the participants’ social lives. In support of the Learning Hypothesis, age proved to be a strong predictor of interest in celebrities. In partial support of the Parasocial Hypothesis, media exposure, but not social isolation, was a strong predictor of interest in celebrities. The preliminary results support both theories, indicate that across our life span celebrities move from being teachers to being friends, and open up a list of future research opportunities. (shrink)
