This article presents the results from two prototypicality tests conducted to find evidence that the differences in the representativity of indirect request and command utterances depend on the centrality of the components of the respective cognitive models that are instantiated and the degree to which they are present in the utterances. This study draws on Thornburg and Panther's (1997) metonymic approach, which was further developed by Pérez Hernández and Ruiz de Mendoza (2002). The results of the analysis confirm the initial hypothesis.
