Study links semantic relevance and lexical expectation to reading brain activity

By PulseAugur Editorial · [2 sources] ·

A new study published on arXiv explores how semantic integration and lexical expectation influence neural responses during naturalistic reading. Researchers used EEG data from 22 participants and compared two predictors: GPT-based word surprisal and a measure of contextual semantic relevance. Both predictors showed associations with neural activity, but contextual semantic relevance provided additional explanatory value, particularly in the P600 window, suggesting that reading comprehension relies on both lexical expectancy and local semantic integration.
