Bilingualism and Attention in Typically Developing Children and Children With Developmental Language Disorder

Purpose: The aim of the current study was to investigate whether dual language experience modulates the efficiency of the 3 attentional networks (alerting, orienting, and executive control) in typically developing (TD) children and in children with developmental language disorder (DLD).Method: We examined the attentional networks in monolingual and bilingual school-aged children (ages 8–12 years) with and without DLD. TD children (35 monolinguals, 23 bilinguals) and children with DLD (17 monolinguals, 9 bilinguals) completed the Attention Network Test (Fan et al., 2002; Fan, McCandliss, Fossella, Flombaum, & Posner, 2005).Results: Children with DLD exhibited poorer executive control than TD children, but executive control was not modified by bilingual experience. The bilingual group with DLD and both TD groups exhibited an orienting effect, but the monolingual group with DLD did not. No group differences were found for alerting.Conclusions: Children with DLD have weak executive control skills. These skills are minimally influenced by dual language experience, at least in this age range. A potential bilingual advantage in orienting may be present in the DLD group.</p

Bilingualism and processing speed in typically developing children and children with developmental language disorder.

Purpose: The aim of the current study was to investigate whether dual language experience modulates processing speed in typically developing (TD) children and in children with developmental language disorder (DLD). We also examined whether processing speed predicted vocabulary and sentence-level abilities in receptive and expressive modalities. Method: We examined processing speed in monolingual and bilingual school-age children (ages 8–12 years) with and without DLD. TD children (35 monolinguals, 24 bilinguals) and children with DLD (17 monolinguals, 10 bilinguals) completed a visual choice reaction time task. The Clinical Evaluation of Language Fundamentals, the Peabody Picture Vocabulary Test, and the Expressive Vocabulary Test were used as language measures. Results: The children with DLD exhibited slower response times relative to TD children. Response time was not modified by bilingual experience, neither in children with typical development nor children with DLD. Also, we found that faster processing speed was related to higher language abilities, but this relationship was not significant when socioeconomic status was controlled for. The magnitude of the association did not differ between the monolingual and bilingual groups across the language measures. Conclusions: Slower processing speed is related to lower language abilities in children. Processing speed is minimally influenced by dual language experience, at least within this age range.</p

Motor issues in specific language impairment: A window into the underlying impairment

Contains fulltext : 150655.pdf (publisher's version ) (Closed access)This paper reviews the findings of recent studies examining the motor abilities of children with specific language impairment (SLI). Standardized measures of motor ability confirm that children with SLI exhibit deficits in fine and gross motor skill, both simple and complex. These difficulties also extend to speech-motor ability, particularly with the control of their articulatory movements. Communicative gesturing, on the other hand, does not appear to be significantly impacted in SLI. Some of the latest studies reviewed in this paper have examined motor processes supported by procedural memory, which is argued to be impaired in SLI. The results of these studies indicate that children with SLI have difficulty with motor sequence learning, but may show deficits in other procedural motor processes as well. Despite significant progress with understanding the motor issues in SLI, future studies are needed to hone in on the nature of this impairment.9 p
