Researchers have investigated the interplay between hierarchical syntactic structure and statistical factors in natural language comprehension. Using co-registered EEG and eye-tracking data, they found that syntactic structure influences reading even before a word is encountered, with readers prioritizing syntactically central words over simple sequential order. While hierarchical structure generally carries more predictive weight than statistical features, its influence on neural activity is sometimes weaker than lexical surprisal, indicating that its strength varies across different aspects of reading behavior.
