Word-finding difficulties (WFDs) in children have been hypothesized to be caused at least partly by poor semantic knowledge. Therefore, improving semantic knowledge should decrease word-finding errors. Previous studies of semantic therapy for WFDs are inconclusive. To investigate the effectiveness of semantic therapy for secondary school-aged pupil...

Little evidence exists for the effectiveness of therapy for children with receptive language difficulties, particularly those whose difficulties are severe and persistent. To establish the effectiveness of explicit speech and language therapy with visual support for secondary school-aged children with language impairments focusing on comprehension...

This article summarizes the evidence as regards the effectiveness of therapy for grammar for school-aged children with language impairments. I first review studies focusing on specific areas of grammar (both expressive and receptive targets) and then studies aiming to improve language more generally, several of which focus more on the effectiveness...

Background: Evidence of the effectiveness of therapy for older children with (developmental) language disorder (DLD), and particularly those with receptive language impairments, is very limited. The few existing studies have focused on particular target areas, but none has looked at a whole area of a service. Aims: To establish whether for stude...

Background Paediatric speech and language therapist (SLT) roles often involve planning individualized intervention for specific children, working collaboratively with families and education staff, providing advice, training and coaching and raising awareness. A tiered approach to service delivery is currently recommended whereby services become inc...

Introduction Developing daily living skills, such as self-care, cooking and managing money, is a key priority for adolescents with special educational needs. Previous studies investigated the emergence of daily living skills in young people with a range of neurodevelopmental conditions. However, none focused on adolescents with language disorders,...

Solving word problems is challenging for many children, but particularly for those with language difficulties. The objective was to examine the nature of the challenges experienced by children with language difficulties as they solved word problems in the context of a developmental-trajectory instructional sequence. We recruited 45 third graders wi...

Purpose We investigated the effectiveness of a highly individualized morphosyntactic intervention using the SHAPE CODING™ system delivered at different dosages. Method Eight children with developmental language disorder aged 8;0–10;10 (years;months) received 10 hr of explicit individualized intervention for morphosyntax delivered in 30-min individ...

(1) Background: While spoken language learning delays are assumed for deaf and hard of hearing (DHH) children after cochlear implant (CI), many catch up with their hearing peers. Some DHH children with CIs, however, show persistent delays in language, despite protective factors being in place. This suggests a developmental language disorder (DLD)....

To explore the clinical potential of grammaticality judgement tasks, this study investigated whether a Grammaticality Judgment Task (GJT) of inflectional morphology could differentiate between a clinically selected sample of children with DLD and children in mainstream (i.e. regular education) schools. We also explored the relationship between gram...

Current methods for reporting interventions do not allow key questions of importance to practitioners, service providers, policy‐makers and people with DLD to be answered, and hence limit the implementation of effective interventions in the real world. To extend the existing EQUATOR guidelines to the context of speech language therapy/pathology for...

Background Adjectives are essential for communication, conceptual development and academic success. However, they are semantically and syntactically complex and can be particularly challenging for children with Developmental Language Disorder (DLD). Surprisingly, language interventions have not typically focused on this important word class. Aims...

Background: People with language disorders (including developmental language disorder-DLD) often struggle to learn new words and, for young adults, this could affect their success in future work. Therefore, it is crucial to support their learning of career-specific vocabulary. However, little published evidence exists regarding the effectiveness o...

La résolution de problèmes mathématiques à énoncé verbal est un défi pour les enfants au développement typique qui est d'autant plus importantes pour les enfants avec un trouble développemental du langage oral (TDL ; Cross et al., 2018). Toutefois, il n'existe pas de littérature décrivant leurs difficultés spécifiques. L'objectif de notre recherche...

Developmental language disorder (DLD) is one of the most common neurodevelopmental conditions, yet is chronically underserved, with far fewer children receiving clinical services than expected from prevalence estimates, and very little research attention relative to other neurodevelopmental conditions of similar prevalence and severity. This editor...

Background: Adjectives are essential for communication, conceptual development, and academic success. However, they are semantically and syntactically complex and can be particularly challenging for children with Developmental Language Disorder. Surprisingly, language interventions have not typically focused on this important word class.Aims: 1) To...

Aims This study compared two dose frequency conditions of an explicit intervention with 50 trials per session designed to improve past tense marking in early school-aged children with developmental language disorder (DLD). The influence of allomorphs on intervention effects was also examined. Methods Data from previously conducted intervention stu...

This study aimed to assess the effectiveness of Electropalatography (EPG) intervention in targeting specific phonemes/words in seven adolescents aged 14:10–18:06 with co-occurring speech sound and language disorders. Progress on individualised targets versus controls was evaluated following intervention undertaken as part of the participants’ usual...

Previous research has established that children with developmental language disorder (DLD) have difficulties producing inflectional morphology, in particular, finiteness marking. However, other categories of inflectional morphology, such as possessive ‘s nominal inflection remain relatively unexplored. Analyses of the characteristics for marking in...

Purpose The aim of the study was to evaluate the efficacy of a theoretically motivated explicit intervention approach to improve regular past tense marking for early school-age children with developmental language disorder (DLD). Method Twenty-one children with DLD (ages 5;9–6;9 [years;months]) were included in a crossover randomized controlled tr...

Purpose: This study evaluated the efficacy of an explicit combined metalinguistic training and grammar facilitation intervention aimed at improving regular past tense marking for nine children aged 5;10-6;8 years with DLD. Method: This study used an ABA across participant multiple baseline single case experimental design. Participants were seen 1:1...

Method This study used an ABA across-participant multiple-baseline single-case experiment...

Purpose This article summarizes the shared principles and evidence underpinning methods employed in the three sentence-level (syntactic) grammatical intervention approaches developed by the authors. We discuss associated clinical resources and map a way forward for clinically useful research in this area. Method We provide an overview of the princ...

Background: Idiom skills are essential for children to access age-appropriate media, curriculum resources and teaching. Children with developmental language disorder (DLD) require support to develop the ability to understand and define idioms. However, research investigating one-to-one and classroom-based idiom skill intervention for children with...

Background and aims Little evidence exists for the effectiveness of intervention for older adolescents and young adults with language disorders, particularly for those over 16 years. This study involves college-aged students aged 16–19 years with Language Disorder and Word-Finding Difficulties and investigates whether progress in word finding follo...

SprachtherapeutInnen sind in der Folge eingeschlossen) sowie an logopädischen Maßnahmen beteiligte Berufsgruppen unterstützen, sich über aktuelle internationale Entwicklungen zur Terminologie der Sprachentwicklungsstörung und damit verbundenen veränderten diagnostischen Kriterien zu...

Well, the speech–language therapist comes to talk to us occasionally, but they don't help children anymore. (head teacher response to the governing body when asked about the provision for children with language deficits within a mainstream primary school)

This pilot study aims to evaluate the effectiveness of a school-based intervention using visual strategies for improving accurate use of auxiliary and copula marking in singular and plural, past and present tense by students with moderate learning disability and complex needs. Eleven students, aged 10–14 years, in a specialist school based in the U...

Background: Children with developmental language disorder (DLD) frequently have difficulties with word learning and understanding vocabulary. For these children, this can significantly impact on social interactions, daily activities and academic progress. Although there is literature providing a rationale for targeting word learning in such childr...

Speech-language pathologists (SLPs) are increasingly required to read, interpret and create evidence regarding the effectiveness of interventions. This requires a good understanding of the strengths and weaknesses of different intervention study designs. This paper aims to take readers through a range of designs commonly used in speech-language pat...

Background: Language and educational outcomes for adolescents with developmental language disorders (DLD) are often poor, impacting on quality of life in adulthood. Previous cohort studies show changes on measures of language and literacy which either parallel that of typically developing (TD) children at a lower level or (for vocabulary) an increa...

Delayed or impaired language development is a common developmental concern, yet there is little agreement about the criteria used to identify and classify language impairments in children. Children's language difficulties are at the interface between education, medicine and the allied professions, who may all adopt different approaches to conceptua...

It has been suggested that difficulties with tense and agreement marking are a core feature of language impairment. Hence, studies are required that analyse the effectiveness of intervention in this area, including consideration of whether changes seen in therapy sessions generalize to spontaneous speech. This study assessed the effectiveness of th...

It is my great pleasure to introduce this special issue on specific language impairment (SLI). The special issue re-examines the diagnostic criteria for SLI and questions whether the term ‘SLI’ should continue be used as a diagnostic label for children with ‘unexplained language problems’ (the term used by Bishop 2014 in her lead article).

Correct use of verb argument structure relies on accurate verb semantic representations whose formation depends partly on use of reverse linking. We predicted that children with Specific Language Impairment (SLI), who have difficulties with reverse linking, would have inaccurate semantic representations for verbs and hence difficulties with verb ar...

Non-word repetition (NWR) difficulties are common, but not universal, among children with specific language impairment (SLI). However, older children and adolescents with SLI have rarely been studied. Studies disagree on the relationship between NWR difficulties and difficulties with other areas of language and literacy. There is also no consensus...

Purpose The authors aimed to establish whether 2 theoretically motivated interventions could improve use of verb argument structure in pupils with persistent specific language impairment (SLI). Method Twenty-seven pupils with SLI (ages 11;0–16;1) participated in this randomized controlled trial with “blind” assessment. Participants were randomly a...

This paper describes an approach to teaching grammar which has been designed for school-aged children with specific language impairment (SLI). The approach uses shapes, colours and arrows to make the grammatical rules of English explicit. Evidence is presented which supports the use of this approach with older children in the areas of past tense mo...

The results of a pilot study into meta-syntactic therapy using visual coding for four children (age 11-13 years) with severe receptive and expressive specific language impairment (SLI) are presented. The coding system uses shapes, colours and a system of arrows to teach grammatical rules. A time-series design established baseline pre-therapy measur...

The speech and language processing abilities of a 10 year old with a severe hearing impairment and additional word retrieval difficulties are examined at a single word level using Stackhouse and Wells’ psycholinguistic framework. Performance on a variety of output tasks is compared and input processing is investigated in detail. Evidence is found f...

Children with Specific Language Impairment (SLI) have difficulty with, amongst other things, non-word repetition tasks. This paper presents preliminary research into the nature of the phonological deficit in SLI. We report results from four SLI children tested on a new set of non-words which, unlike previous sets, takes metrical and syllabic comple...
