Sensitivity to the acoustic correlates of lexical stress and their relationship to reading in skilled readers

lexical stress, multisyllabic words, reading, comprehension the role of suprasegmental information in reading processes is a growing area of interest, and sensitivity to lexical stress has been shown to explain unique variance in reading development.however, less is known about its role in skilled reading.this study aimed to investigate the acoustic features of suprasegmental information using a same/different cross-modal matching task.sixtyfour adult participants completed standardized measures of reading accuracy, reading speed, and comprehension and performed an experimental task.the experimental task required the participants to identify whether non-speech acoustic sequences matched the characteristics of written words.the findings indicated differences in responses depending on where the lexical stress was required for the word.Moreover, evidence was found to support the view that amplitude information is part of the word knowledge retrieval process in skilled reading.the findings are discussed relative to models of reading and the role of lexical stress in lexical access.
