The overarching aim of the sabbatical leave wiil be to contribute to a more realistic modeling of simultaneous interpreting by offering an analysis in terms of 4EA Cognition and by triangulating experimental and corpus-based approaches. Although various aspects of enaction, embeddedness, embodiment, extension and affect have independently been shown to be relevant for interpreting, their relationship with cognitive processes is still unexplored. Cognitive research in interpreting still considers cognitive processes as self-contained and purely intra-cranial. First, a review of the literature wiil identify gaps and areas in which existing studies are worth expanding with a cognitive dimension. In four studies I wiil then cover all dimensions of 4EA Cognition: enacted, embodied, embedded, extended and affected cognition. The studies wiil concentrate on remote interpreting, computer-assisted interpreting, interpreters' responses to face threatening acts and gestures accompanying the interpreting process. For each study, except probably the one on face threatening acts, experimental and corpus-based methods wiil be combined to ensure proper triangulation. Existing methods wiil be applied and improved and new methods wiil be developed, in particular, with regard to corpus-based approaches. Corpus methods promise not only to allow us to detect points of high cognitive load, but also to find tracés of specific cognitive processes. The four studies wiil be presented in a monograph together with the literature review and a proposal to model interpreting accordjng to 4EA Cognition principles.
