Since norms for vocabulary acquisition in Lebanese bilingual children (L1: Lebanese, L2: French and/or English) do not yet exist, clinical assessment based on normative data and using appropriate tools remains difficult for speech and language therapists. The current study focuses on exploring and comparing lexical performances of typically developing Lebanese bilingual children (32 Bi-TD, aged 5;7 to 6;9) and those with specific language impairment (10 Bi-SLI, aged 5;9 to 7;10), using cross-linguistic lexical tasks (LITMUS-CLT, COST Action IS0804, 2011) in Lebanese Arabic language (CLT-LB), specific to the Lebanese context...

PURPOSE: This study investigated aspects of morphology, syntax and pragmatics in children with Specific Language Impairment (SLI). These areas of language were investigated by evaluating children's answers to wh-questions. METHOD: Elicited production methodology was used to evoke answers to three types of wh-questions. There were 54 participants: 18 children with SLI (mean age = 5;3); 18 language-matched children matched on mean length of utterance (mean age = 3;4) and 18 age-matched children (mean age = 5;3)...

BACKGROUND: A limited number of studies have analyzed grammaticality in monolingual Spanish-speaking children with specific language impairment (SLI). Most of the available data are based on bilingual speakers. AIMS: To extend previous studies by doing a more detailed analysis of grammatical types in monolingual Spanish-speakers with and without SLI. METHODS & PROCEDURES: Forty-nine Spanish-speaking children (18 with SLI, 17 age-matched typically developing controls, 14 language-matched controls) were recruited from schools in Mexico and observed in a spontaneous narrative task...

Deficits in the production of verbal inflection (tense marking, or finiteness) are part of the Optional Infinitive (OI) stage of typical grammatical development. They are also a hallmark of language impairment: they have been used as biomarkers in guiding genetic studies of Specific Language Impairment (SLI), and have also been observed in autism spectrum disorders (ASD). To determine the detailed nature of finiteness abilities in subgroups of ASD [autism with impaired language (ALI) vs. autism with normal language (ALN)], we compared tense marking abilities in 46 children with ALI and 37 children with ALN with that of two groups of nonverbal mental age (MA) and verbal MA-matched typically developing (TD) controls, the first such study described in the literature...

OBJECTIVES: Contralateral masking of transient-evoked otoacoustic emissions is a phenomenon that suggests an inhibitory effect of the olivocochlear efferent auditory pathway. Many studies have been inconclusive in demonstrating a clear connection between this system and a behavioral speech-in-noise listening skill. The purpose of this study was to investigate the activation of a medial olivocochlear (MOC) efferent in children with poor speech-in-noise (PSIN) performance and children with language impairment and PSIN (SLI + PSIN)...

Purpose: this study investigated and compared the performance of school-aged children with specific language impairment (SLI) and their peers typically developing language in alliteration and rhyme tests. The study also aimed to evaluate the influence of semantic and phonological distractors on both tests. Methods: twelve school-aged children with SLI (study group - SG) and 48 peers typically developing language (control group - CG) aged 7 to 9 years. All of them were on 2nd or 3rd grade and presented hearing thresholds within normal limits and appropriate nonverbal intellectual performance...

The current study proposes a new bi-factor rotation method, Schmid-Leiman with iterative target rotation (SLi), based on the iteration of partially specified target matrices and an initial target constructed from a Schmid-Leiman (SL) orthogonalization. SLi was expected to ameliorate some of the limitations of the previously presented SL bi-factor rotations, SL and SL with target rotation (SLt), when the factor structure either includes cross-loadings, near-zero loadings, or both. A Monte Carlo simulation was carried out to test the performance of SLi, SL, SLt, and the two analytic bi-factor rotations, bi-quartimin and bi-geomin...

Specific Language Impairment (SLI) remains an underinvestigated disorder in morphologically complex agglutinative languages such as Kannada. Currently, only a few case reports are available on SLI in Dravidian languages. The morphological complexity inherent to Dravidian languages such as Kannada provides a potential avenue to verify one of the two prevailing accounts of SLI: the morphological richness theory and CGC (Computational Grammatical Complexity) hypothesis. While the previous theory predicts the relatively spared performance of children with SLI (CwSLI) on syntactic morphology in morphologically complex languages, the latter predicts a diametrically opposite performance...

Analogical reasoning is a human ability that maps systems of relations. It develops along with relational knowledge, working memory and executive functions such as inhibition. It also maintains a mutual influence on language development. Some authors have taken a greater interest in the analogical reasoning ability of children with language disorders, specifically those with specific language impairment (SLI). These children apparently have weaker analogical reasoning abilities than their aged-matched peers without language disorders...

BACKGROUND: This study aimed to identify risk factors associated with specific language impairment (SLI). METHODS: In a nested case-control design, 253 children attending special needs schools for severe speech and language difficulties in the Netherlands were matched for sex and date of birth with 253 children attending mainstream education. Data on perinatal, maternal and family issues were retrieved from well-child care files registered shortly after birth. RESULTS: Children with SLI had younger mothers than children in the control group (mean 30 years 9 months vs...

BACKGROUND: A low serum total bilirubin (T-bil) level is associated with an increased risk of atherosclerosis. However, the differential impact of the serum T-bil level on cerebral atherosclerosis and cerebral small vessel disease (SVD) is still unclear. METHODS: We evaluated serum T-bil levels from 1,128 neurologically healthy subjects. Indices of cerebral atherosclerosis (extracranial arterial stenosis [ECAS] and intracranial arterial stenosis [ICAS]), and indices of SVD (silent lacunar infarct [SLI], and moderate-to-severe white matter hyperintensities [msWMH]) were evaluated by the use of brain magnetic resonance imaging (MRI) and MR angiography...

Deficits in social communication, particularly pragmatic language, are characteristic of individuals with autism spectrum disorder (ASD). Speech disfluencies may serve pragmatic functions such as cueing speaking problems. Previous studies have found that speakers with ASD differ from typically developing (TD) speakers in the types and patterns of disfluencies they produce, but fail to provide sufficiently detailed characterizations of the methods used to categorize and quantify disfluency, making cross-study comparison difficult...

Understanding the genetic factors underlying neurodevelopmental and neuropsychiatric disorders is a major challenge given their prevalence and potential severity for quality of life. While large-scale genomic screens have made major advances in this area, for many disorders the genetic underpinnings are complex and poorly understood. To date the field has focused predominantly on protein coding variation, but given the importance of tightly controlled gene expression for normal brain development and disorder, variation that affects non-coding regulatory regions of the genome is likely to play an important role in these phenotypes...

Current systems to study essential genes in the human malaria parasite Plasmodium falciparum are often inefficient and time intensive, and they depend on the genetic modification of the target locus, a process hindered by the low frequency of integration of episomal DNA into the genome. Here, we introduce a method, termed selection-linked integration (SLI), to rapidly select for genomic integration. SLI allowed us to functionally analyze targets at the gene and protein levels, thus permitting mislocalization of native proteins, a strategy known as knock sideways, floxing to induce diCre-based excision of genes and knocking in altered gene copies...

Purpose: This study investigated nonadjacent dependency learning in Cantonese-speaking children with and without a history of specific language impairment (SLI) in an artificial linguistic context. Method: Sixteen Cantonese-speaking children with a history of SLI and 16 Cantonese-speaking children with typical language development (TLD) were tested with a nonadjacent dependency learning task using artificial languages that mimic Cantonese. Results: Children with TLD performed above chance and were able to discriminate between trained and untrained nonadjacent dependencies...

Purpose: Given the complexity of sentence processing and the specific problems that children with specific language impairment (SLI) experience, we investigated the time course and characteristics of semantic processing at the sentence level in Dutch preschoolers with SLI. Method: We measured N400 responses to semantically congruent and incongruent spoken sentences (e.g., "My father is eating an apple/*blanket") in a group of 37 Dutch preschoolers with SLI and in a group of 25 typically developing (TD) peers...

Impaired procedural learning has been suggested as a possible cause of developmental dyslexia (DD) and specific language impairment (SLI). This study examined the relationship between measures of verbal and non-verbal implicit and explicit learning and measures of language, literacy and arithmetic attainment in a large sample of 7 to 8-year-old children. Measures of verbal explicit learning were correlated with measures of attainment. In contrast, no relationships between measures of implicit learning and attainment were found...

Purpose: This study tested the feasibility of a method designed to assess children's sensitivity to tense/agreement information in fronted auxiliaries during online comprehension of questions (e.g., Are the nice little dogs running?). We expected that a group of children who were proficient in auxiliary use would show this sensitivity, indicating an awareness of the relation between the subject-verb sequence (e.g., dogs running) and preceding information (e.g., are). Failure to grasp this relation is proposed to play a role in the protracted inconsistency in auxiliary use in children with specific language impairment (SLI)...
