Abstract: | Past theories concerned with communicative competence have assumed that perceiver's evaluations of the competence of a communicative performance are based on a conception of the “ideal communicator.” Psychological theory on categorization implies that this assumption is most viable if conceptions of “prototypes” relevant to competence in general (“the communicatively competent person”) are rich in defining characteristics relative to their logical superordinate (“the skilled person”), yet distinct from other skill-related prototypes (such as “the artistically talented person”), and if conceptions of prototypes relevant to competence in specific interactive situations are also relatively rich in defining characteristics, but similar to one another. Analysis of freely elicited lists of characteristics for categories within a taxonomic hierarchy for skill support these implications, showing that people's conceptions of “communicative competence” are organized in the manner most conducive to their use as the basis for competence evaluation. Results also point out the critical role played by concrete, rather than abstract, characteristics in differentiating among general and situation-specific prototypes. |
