Danica Seleskovitch, representative of the Paris School, claims that perception/comprehension, deverbalization and expression constitute a triangular model of interpreting rather than a linear process of message/sense transfer. This article, by tracking the generation of this interpreting model and reflecting upon its theoretical values and deficiencies, argues that this very triangular model, though failing to elaborate on the hypothesis of deverbalization and how linguistic information is processed in interpreting, is a bold theoretical innovation which helps accelerate the cognitive psychological turn of international interpreting studies and serves as great inspiration for the emergence of ensuing information processing models of interpreting. Then the article, based on the theories of modern cognitive psychology, proposes that the processing of linguistic information in interpreting is accomplished through the combination of controlled and automatic processing, serial and parallel processing and top-down and bottom-up processing.
