What's behind the smile?

  • John J. Ohala (a1)
Abstract
Abstract

Many species' non-threat facial expression involves an open mouth and retracted lip corners – the smile. This served to make an accompanying vocalization sound like it originated from a smaller vocalizer. That such signals are deceptive and benefit primarily the signaler undermines the notion that the perception of the smile employs embodied simulation of the smiler's state.
