Listener’s personality traits predict changes in pupil size during auditory language comprehension

Abstract Research suggests that listeners’ comprehension of spoken language is concurrently affected by linguistic and non-linguistic factors, including individual difference factors. However, there is no systematic research on whether general personality traits affect language processing. We correl...
