Talia Isaacs is an Associate Professor of Applied Linguistics and TESOL and programme leader for the MA TESOL In-Service at the UCL Institute of Education, University College London. She is well known for her work on second language speaking assessment, with emerging research interests particularly in language for specific purposes, technology-mediated assessment, and classroom-based assessment. Her main exposure to eye-tracking has been through collaborating on a project led by Guoxing Yu on the use of this technology to elucidate test-takers’ cognitive processes on IELTS writing tasks and through examining doctoral theses that use an eye-tracking component as part of mixed-methods studies. She is interested in the applications of eye-tracking to address substantive questions, for example, related to strategy use during task completion and information processing given varying degrees of complexity in the input.
