Awareness of Rhythm Patterns in Speech and Music in XXXX with Specific @entity73 .

@entity1 @entity73 @entity22294 @entity10870
@entity1 with @entity10870 ( @entity10870 ) show @entity73 and production of language, and also @entity73 in perceiving auditory cues to rhythm [amplitude rise time (ART) and sound duration] and in tapping to a rhythmic beat. Here we explore potential links between language development and rhythm perception in 45 @entity1 with @entity22294 and 50 age-matched controls. We administered three rhythmic tasks, a musical beat detection task, a tapping-to-music task, and a novel music/speech task, which varied rhythm and pitch cues independently or together in both speech and music. Via low-pass filtering, the music sounded as though it was played from a low-quality radio and the speech sounded as though it was muffled (heard "behind the door"). We report data for all of the @entity22294 @entity1 (N = 45, IQ varying), as well as for two independent subgroupings with intact IQ. One subgroup, "Pure @entity22294 ," had intact phonology and reading (N = 16), the other, " @entity22294 PPR" (N = 15), had impaired phonology and reading. When IQ varied (all @entity22294 @entity1 ), we found significant group differences in all the rhythmic tasks. For the Pure @entity22294 group, there were @entity73 in the tapping task only. For @entity1 with @entity22294 and poor phonology ( @entity22294 PPR), group differences were found in all of the filtered speech/music AXB tasks. We conclude that difficulties with rhythmic cues in both speech and music are present in @entity1 with @entity10870 , but that some rhythmic measures are more sensitive than others. The data are interpreted within a "prosodic phrasing" hypothesis, and we discuss the potential utility of rhythmic and musical interventions in remediating speech and language difficulties in @entity1 .
