The traditional view that gestures play an important role in communication is so widespread and well-entrenched that comparatively little research has been done to assess the magnitude of their contribution, or to determine the kinds of information different types of gestures convey.  Reviewing such evidence as exists, Kendon has concluded:The gestures that people produce when they talk do play a part in communication and they do provide information to со participants about the semantic content of the utterances, although there clearly is variation about when and how they do so (Kendon 1994, p. 192).
