Rapid facial mimicry in orangutan play.

ABSTRACT: Emotional contagion enables individuals to experience emotions of others. This important empathic phenomenon is closely linked to facial mimicry, where facial displays evoke the same facial expressions in social partners. In humans, facial mimicry can be voluntary or involuntary, whereby its latter mode can be processed as rapid as within or at 1s. Thus far, studies have not provided evidence of rapid involuntary facial mimicry in animals. This study assessed whether rapid involuntary facial mimicry is present in orangutans (Pongo pygmaeus; N=25) for their open-mouth faces (OMFs) during everyday dyadic play. Results clearly indicated that orangutans rapidly mimicked OMFs of their playmates within or at 1s. Our study revealed the first evidence on rapid involuntary facial mimicry in non-hum
