Cortical speech tracking is related to individual prediction tendencies

HIGHLIGHTS

SUMMARY

    The correlation between predicted brain activity from speech envelope encoding and true brain activity was used as dependent variable, and separate models were calculated per voxel using the following formula according to the Wilkinson notation (Wilkinson and Rogers 1973): cortical tracking ~ n_distractors * prediction_tendency + (1|subject_id). To investigate the inf luence of background noise and individual prediction tendency on subjective perception the authors calculated 2 bayesian multilevel models using the following formulas: difficulty ~ n_distractors * prediction_tendency + (1|subject_id). engagement ~ n_distractors * prediction_tendency + (1|subject_id). Cortical tracking ~ n_distractors + (1|subject_id). | Cerebral Cortex, 2023 number of distractors for words . . .
