that participants produce gestures which are more similar in terms
of handshape when they can see each other than when they cannot.
Parrill and Kimbara (2006), also working on experimental data, note
that observing mimicked gestures induces more mimicry in the
participants. They consider a gesture is repeated when two of the
following features are reproduced: motion, handshape or location.
Hand-gesture features are also central in Mol et al. (2012) who state
that imitators in laboratory speech are influenced in their mimicry by
features of the original gesture, for instance handedness. They show
as well that participants are influenced in their ...
