▶️ Paired with e.g. qualitative annotations of specific communicative strategies, our findings may help to explain the development of shared communicative conventions. #iconicity #conventionalisation

📊 According to our predictions, participants showed a shift from whole-body pantomimes to more economical and specialised manual gestures: 1. hand & arm movement increased 📈, 2. the path and volume of the moved articulators decreased 📉 🙆🙅‍♂️🙌🤲👋

⚙️Across four rounds of of a communication game, participants had to use whole-body pantomimes to communicate and guess a set of transitive actions. They were dressed in #MoCap suits to record their movements

💡 Gestural and pantomimic hypotheses in language evolution research highlight the need for communicative efficiency, leading to the evolution of reduced, less costly forms of communication over time. We tested this in a motion-capture study 🦾
