Recent studies in the psychological literature reveal that cospeech gestures facilitate the construction of an articulated mental model of an oral discourse by hearing individuals. In particular, they facilitate correct recollections and discourse-based inferences at the expense of memory for discourse verbatim. Do gestures accompanying an oral discourse facilitate the construction of a discourse model also by oral deaf individuals trained to lip-read? The atypical cognitive functioning of oral deaf individuals leads to this prediction. Experiments 1 and 2, each conducted on 16 oral deaf individuals, used a recollection task and confirmed the prediction. Experiment 3, conducted on 36 oral deaf individuals, confirmed the prediction using a recognition task.When people talk, they make spontaneous movement of arms, hands, and heads, called cospeech gestures. These gestures are closely time-locked to the syntactic and semantic properties of speech. McNeill (1992) identifies a number of different types of cospeech gestures: iconic gestures, which capture aspects of the semantic content of speech; metaphoric gestures, which convey abstract pictorial content; beat gestures, which occur along with the rhythmical pulsation of speech; and deictic or pointing gestures, which indicate entities in the conversation. A series of experimental studies suggest that cospeech gestures have a role both for the speaker, because they favour the organisation of thinking (e.g.
