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. 相似文献

Three factors that have transformed perceptual research in the last fifty years are the digital computer, single-unit electrophysiology, and molecular biology. Amongst the developments in which members of the Experimental Psychology Society have been central are: the recognition of the role of optic flow in spatial vision; the demonstration that our perceptual systems contain parallel pathways extracting different information from the sensory array; the identification of specific detectors that can be selectively adapted in psychophysical experiments; and the transfer of the concepts of fourier analysis from audition to vision. The history of Opponent Process Theory offers an example where experimental psychologists have been misled by too simple an interpretation of physiological recordings. 相似文献
