The whole picture: Processing of numbers and their context in simultaneous interpreting

Abstract This paper presents an eye-tracking study in which number processing in simultaneous interpreting was investigated. Interpreting accuracy and eye behaviour were studied together to unveil the processing and rendering of numbers by interpreting trainees (N = 22) and professional interpreters (N = 26). While professional interpreters rendered numerals and the context in which they appeared with better accuracy, there was also a positive correlation between number interpreting accuracy and context interpreting accuracy. Our results indicate that interpreting arithmetic values of numerals is more cognitively demanding than interpreting their context, which is reflected in longer mean fixation duration on numbers than on the elements they referred to. Further research is needed to investigate numerical data processing in other tasks, involving other language pairs and interpreting directionality. The study outcomes may be a useful contribution to research on the cognitive aspects of simultaneous interpreting, numerical data processing, as well as interpreter training.
