• The extraction of structure during reading: Evidence from reading prosody

  According to the structural approach to reading, the extraction of structure precedes the analysis of meaning and paves the way for it. In this study, reading prosody was used to examine this proposition. Specifically, we tested the hypothesis that reading prosody produced on line reflects the early extraction of structure. In Experiment 1, readers were successful in assigning natural prosody to unfamiliar text immediately upon its reading. Experiment 2 showed that the prosodic patterns applied are tuned to the structure of the sentence and are largely indifferent to the content of the sentence or to its semantic coherence. The results join with other findings in speech production and comprehension in supporting the precedence of structure to meaning in reading.
