Background: The purpose of this study was to examine the stability of behavioural, emotional and social difficulties (BESD) in children with specific speech and language difficulties (SSLD), and the relationship between BESD and the language ability. Methods: A sample of children with SSLD were assessed for BESD at ages 8, 10 and 12 years by both…

Background: Impairments in language and communication are core features of autism spectrum disorders (ASDs). The basis for this association is poorly understood. How early language is related to each of the triad of impairments characteristic of ASDs is also in need of clarification. Aims: This is the first study that aims to determine the extent…

Purpose: This study compared performance of children on 2 tests of nonword repetition to investigate the factors that may contribute to the well-documented nonword repetition deficit in specific language impairment (SLI). Method: Twelve children with SLI age 7 to 11 years, 12 age-matched control children, and 12 control children matched for…

The aim of this study was to evaluate if a diagnostic work-up should be recommended for 2-year-old children with developmental language delay (LD), or if the widely chosen "wait and see" strategy is adequate. Children with LD were identified in paediatric practices during routine developmental check-ups using a German parent-report…

This study investigated whether genes affect language impairment to the same extent as they affect differences in language ability following up an earlier study of 579 four-year-old twins with low language performance and their cotwins (Viding et al., in press). The present study selected low-language twins from 6,963 pairs of twins from the Twins…

The present study addresses the distinction between specific (SLI) and nonspecific (NLI) language impairment at an etiological level by estimating the relative genetic and environmental contributions to language impairment in children with SLI and NLI. Drawing on a large longitudinal twin study, we tested a sample of 356 four-and-a-half-year-old…

This study examined the relationship between emotion regulation, language ability, and reticent behavior in children with specific language impairment (SLI) and their typical peers. Participants included 43 children with SLI and 43 typically developing children, for a total sample of 86 participants. Children were selected from 2 age ranges: 5-8…

The frequency, course, and inter-relationships of atypical eating, sleeping, self-injurious behavior, aggression and temper tantrums in children with autism and children with a history of language impairment (HLI), was investigated using a parent interview that was created to examine these problem behaviors. The relationships between these…

Examined the conversational patterns of older children with their younger siblings. Findings reveal that the siblings of disabled children appeared to be less conversationally sensitive with their brothers and sisters than the siblings of nondisabled children. (34 references) (Author/CK)

This study of 4-year-old twins investigated the genetic and environmental origins of comorbidity between language impairment and nonverbal ability by testing the extent to which language impairment in one twin predicted nonverbal ability in the co-twin. Impairment of language ability was defined as scores below the 15th percentile on a general…

This article presents a longitudinal study of the early literacy development of 47 children with speech difficulties from ages 4 to 7 years. Of these children, 19 with specific speech difficulties were compared with 19 children with speech and language difficulties and 19 normally developing controls. The risk of literacy difficulties was greater…

Background: We investigated the aetiology of language impairment in 579 four-year-old twins with low language performance and their co-twins, members of 160 MZ twin pairs, 131 same-sex DZ pairs and 102 opposite-sex DZ pairs. Methods: Language impairment in 4-year-olds was defined by scores below the 15th percentile on a general factor derived from…

PURPOSE: This research determined the psychometric quality of a criterion-referenced measure that was thought to measure preschoolers' print-concept knowledge (PCK). METHOD: This measure, titled the Preschool Word and Print Awareness (PWPA), was examined using the partial credit model (PCM) to determine its suitability for use by clinicians,…

This study examined spoken-word recognition in children with specific language impairment (SLI) and normally developing children matched separately for age and receptive language ability. Accuracy and reaction times on an auditory lexical decision task were compared. Children with SLI were less accurate than both control groups. Two subgroups of…

Language impairments are often associated with problems in educational attainments and in acquiring literacy, but speech therapy services to school-aged children are not universally available. If teachers are able to reliably identify those children whose language skills place them at risk, then the specialist services offered by speech and…
