Children with SLI generally exhibit poor sentence comprehension skills. We examined the specific impact of grammatical complexity and lexical frequency on comprehension performance, yielding contrasting results. The present study sheds new light on sentence comprehension in children with SLI by investigating a linguistic factor which has attracted little research interest: the impact of the lexical frequency of known words on sentence comprehension. We also examined the impact of grammatical complexity and sentence length by independently varying these two factors. Fifteen children with SLI, 15 age- and IQ-matched controls, and 15 controls matched on lexical and grammatical skills, performed sentence comprehension tasks in which three linguistic factors were manipulated: lexical frequency (sentences containing words of either low or high lexical frequency), grammatical complexity (sentence containing either a subject relative clause or an object relative clause) and sentence length (either short or long sentences). Results indicated that children with SLI performed more poorly overall compared to age- and IQmatched children and to lexical and morphosyntactic age-matched children. However, their performance was not more affected by either sentence length or clause type than that of control children. Only lexical frequency affected sentence comprehension to a greater extent in children with SLI relative to the control groups, revealing that SLI children’s sentence comprehension abilities are particularly affected by the presence of lowfrequency but familiar words.

The nature and mechanisms of working memory (WM) for musical information remain poorly understood. The aim of this study is to show that musical WM strongly depends upon long-term memory (LTM) mechanisms and requires access to the long-term musical knowledge base. Two groups of participants (musicians and non-musicians) participated first in an implicit learning task during which they heard for about 30 minutes a continuous sequence of tones governed by a new musical grammar. Then, they performed an immediate serial recall task of musical sequences of increasing length; half of the sequences were constructed in accordance to the rules of the new grammar presented during the implicit learning task. Participants have to reproduce the sequences by humming and their performances were calculated on the basis of the deviation between their production and the stimulus needed to be reproduced. The results showed a significant advantage for the lists governed by the grammar previously learned. Overall, this study shows that performance on a musical WM task is enhanced by musical knowledge stored in LTM. This study is the first to demonstrate the dependency of musical WM on musical LTM knowledge, implying that existing models of musical WM need to be extended to account for this WM-LTM interaction.
