BACKGROUND/AIMS: Studies of people with dyslexia have pointed to the ability to perceive the amplitude envelope rise time ("beat" perception) as a possible cause of phonological processing (PhP) difficulties in this population. However, there are very few studies about the relationships between such skills in the non-dyslexic school population.
METHODS: We investigated the influence of the beat perception ability on PhP and reading skills of 93 Brazilian Portuguese-speaking schoolchildren from the 3rd to the 5th year, with data on reading, phonological awareness (PhA), lexical access, phonological operational memory, and perception of amplitude envelope rise time. To verify the possible effects of age, gender, and school grade on the tasks in the study, we directly included these variables in the models.
RESULTS: Modeling structural equations showed that beat perception did not influence PhP or reading skills, but only the tasks of repetition of words and pseudowords. These tasks may be related because of the demand for phonological working memory necessary to perform the beat perception task rather than a possible connection between this and phonological abilities, as reported in the literature.
CONCLUSION: We suspect beat perception could be of relevance only for subjects with altered reading and/or a deficit in PhP. Further studies will indicate whether the rise time of the amplitude envelope is an essential acoustic clue only for those individuals whose PhA ability is not fully present.
