Triangulation of online and offline measures of processing and reception in AVT

This chapter reviews methodologies for investigating the cognitive processing of audiovisual translation products using the triangulation of physiological, psychometric and performance measures. It also provides an analysis of the strengths and limitations of these measures to offer a synthesis of what has been achieved in this field and what remains to be developed. Such triangulation faces many challenges and rewards related to conducting interdisciplinary research that combines tightly-controlled experimental research with real-world, ecologically valid studies. Hence, the discussion emphasises the importance of both borrowing methods from other disciplines, and employing them effectively to add value to the study of film. We call for increased quality and integrity in AVT research to resolve questions on the cognitive processing and reception of AVT products.
Keywords: AVT, eye tracking, triangulation, EEG, post-hoc measures
