Over the past weeks, two new papers were published:
Scientific Reports:
Christoph Strauch, Lukas Greiter and Anke Huckauf investigated the relationship of pupil diameter changes and microsaccade rate in a binary letter selection task. It was found that pupil diameter robustly reflected decision formation and signaled the respective choice, even when brightness changed or a key was pressed.
