Background: Language interventions are complex behavioural interventions, making it difficult to distinguish the specific factors contributing to efficacy. The efficacy of oral language comprehension interventions varies greatly, but the reasons for this have received little attention. Aims: The aim of this meta-analysis was to examine which…

Background: The Language Development Survey (LDS) and the MacArthur-Bates Communicative Development Inventories (MB-CDI) are two parental report forms that have been productive in providing data on early child language during the past 30 years. The instruments have been used both in studies relating to typical developing children and in screening…

Background: Phonological difficulties are prevalent in children with speech and/or language disorders and may hamper their later language outcomes and academic achievements. These children often form a significant proportion of speech and language therapists' caseloads. There is a shortage of information on evidence-based interventions for…

Background: Language disorder and associated vocabulary difficulties can persist into adolescence, and can impact on long-term life outcomes. Previous reviews have shown that a variety of intervention techniques can successfully enhance students' vocabulary skills; however, none has investigated vocabulary intervention specifically for adolescents…

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…

On average, language and communication characteristics of individuals with Down syndrome (the most common genetic cause of intellectual disability) follow a consistent profile. Despite considerable individual variability, receptive language is typically stronger than expressive language, with particular challenges in phonology and syntax. We…

Background: Receptive language impairment (RLI) is one of the most significant indicators of negative sequelae for children with speech and language disorders. Despite this, relatively little is known about the most effective treatments for these children in the primary school period. Aims: To explore the relationship between the reported practice…

By looking at data on expressive phonology, non-word repetition, non-word discrimination and phonological sensitivity in two groups of Swedish children, the common basis for tasks tapping into different levels of phonological processing is discussed. Two studies were performed, one including children with language impairment (LI) and one including…

This article discusses the potential of applying research based on the principles of stimulus equivalence and related phenomena to the investigation and remediation of language disabilities, particularly with individuals with intellectual disabilities and autism. It describes studies which have applied an equivalence framework to different aspects…

This article on oral narratives in school-age children focuses on the changing demands from home to school use of narratives, developmental changes expected in school-age children, differences between narratives of children with and without language disorders, difficulties inherent in current assessment methods, and alternative assessment and…

The performance data of individuals with Alzheimer's on language comprehension and expression tests are presented and discussed in the context of possible contributions from impaired working memory functions. It is argued that diminished scores result primarily from attenuated span capacity, difficulty focusing attention, encoding, and activation…

The impact of a disordered phonological system (expressive or receptive) on language development is examined. Research results and guidelines are presented for identification of critical intelligibility and phonological awareness deficiencies and for intervention. Options for expediting intelligibility gains and research findings on enhancing…

This article reviews the developmental literature in spoken persuasion and discusses implications for assessment and intervention with students with language-learning disorders, in terms of persuading others, analyzing persuasive appeals, and responding to persuasive appeals. (JDD)

This article outlines key components of a medical evaluation of a child who is not talking. Factors to consider during diagnosis and screening are discussed, including the presence of mental retardation, hearing impairments, autism, cerebral palsy, and other disorders. The physiology of speech/language disorders in children is also examined.…
