This study explores the role that gesture plays in the earliest stages of language learning. We describe how one-word speakers use gesture in combination with speech in their spontaneous communications, and interpret gesture presented in combination with speech in an experimental situation. Forty one-word speakers (ages 1;2.22 to 2;4.6) were videotaped in a free-play session which provided data on the child's spontaneous gesture and speech production. The children were also given a comprehension task in which the presence and absence of gesture were systematically varied in relation to speech. We found that (1) all of the children spontaneously produced gestures in combination with speech, and (2) all of the children were able to understand gesture when it was presented in combination with speech, not only when the gesture was redundant with speech but also when the gesture substituted for speech. These data suggest that, even at this young age, gesture naturally forms an integrated system with speech in both production and comprehension.
Glucksberg and Keysar (1990) have proposed a class-inclusion model of metaphor comprehension. This theory suggests that metaphors are not understood as implicit similes but are seen as class-inclusion statements in which the topic of a metaphor is assigned to a diagnostic, ad hoc category, whereas the metaphor's vehicle is a prototypical member of that category. The author claims that verbal metaphors are not simply instantiations of temporary, ad hoc categories but reflect preexisting conceptual mappings in long-term memory that are metaphorically structured. Various evidence from cognitive linguistics, philosophy, and psychology are described in support of this claim. Evidence is also presented that supports, contrary to Glucksberg and Keysar's position, the role of tacit conceptual metaphors in the comprehension of verbal metaphors in discourse.
