Abstract and Keywords
When people speak, they often spontaneously produce hand gestures, which express information related to the information encoded in concurrent speech. This article discusses the relationship between speech production and gesture production, and presents a model based on Levelt’s model of speech production. In the proposed model, speech and gesture production processes are closely linked at the conceptual planning stage. The following topics are covered: how physical and discursive contexts affect gesturing, how the addressee’s knowledge status and perceptual capabilities affect gesturing, how grammatical and lexical choices in speech influences gestural expression of related contents, how the load on conceptualization for speech production influences gesture production, and how gesturing influences what information is expressed in speech and which grammatical structure is chosen in speech.
