Children who require augmentative and alternative communication (AAC) systems while they are in the process of acquiring language face unique challenges because they use graphic symbols for communication. In contrast to the situation of typically developing children, they use different modalities for comprehension (auditory) and expression (visual). This(More)
PURPOSE This study investigated the impact of syntactic complexity and task demands on construction of utterances using picture communication symbols by participants from 3 age groups with no communication disorders. METHOD Participants were 30 children (7;0 [years;months] to 8;11), 30 teenagers (12;0 to 13;11), and 30 adults (18 years and above). All(More)
While research on spoken language has a long tradition of studying and contrasting language production and comprehension, the study of graphic symbol communication has focused more on production than comprehension. As a result, the relationships between the ability to construct and to interpret graphic symbol sequences are not well understood. This study(More)
This study provides a systematic description of French consonant acquisition in a large cohort of pre-school aged children: 156 children aged 20-53 months participated in a picture-naming task. Five analyses were conducted to study consonant acquisition: (1) consonant inventory, (2) consonant accuracy, (3) consonant acquisition, (4) a comparison of(More)
A detailed language assessment was conducted with MM, a 17-year-old bilingual teenager with Rasmussen syndrome who had undergone a left functional hemispherectomy. Results revealed important deficits in French and English, affecting expressive and receptive language in both the written and the oral modality. MM's linguistic profile was coherent with(More)
Children with Down syndrome (DS) have cognitive disabilities resulting from trisomy 21. Language-learning difficulties, especially expressive language problems, are an important component of the phenotype of this population. Many individuals with DS are born into bilingual environments. To date, however, there is almost no information available regarding(More)
Graphic symbols are often used to represent words in Augmentative and Alternative Communication systems. Previous findings suggest that different processes operate when using graphic symbols and when using speech. This study assessed the ability of native speakers of French with no communication disorders from four age groups to interpret graphic-symbol(More)
In order to understand a sequence of graphic symbols as sentences, one must not only recognize the meaning of individual symbols but also integrate their meaning together. In this study children without disabilities were asked to perform two tasks that presented sequences of graphics as stimuli but that differed in the need to treat the symbols as a(More)
PURPOSE Research on the diagnostic accuracy of different language measures has focused primarily on English. This study examined the sensitivity and specificity of a range of measures of language knowledge and language processing for the identification of primary language impairment (PLI) in French-speaking children. Because of the lack of well-documented(More)
According to many studies, Broca's (or non fluent) aphasic patients are younger than Wernicke's (or fluent). Different hypotheses have been proposed to explain this age difference. However, since the studies in which an age difference was observed have not controlled all the variables--such as schooling and handedness--that may have an influence on speech(More)
