Purpose: The development of vocabulary size in deaf/hard of hearing (DHH) children and adolescents can be delayed compared to their peers due to lack of access to early language input. Complementary vocabulary interventions are reported in the literature. Our aim is to evaluate the effectiveness of intervention methods for their vocabulary…

Aided language stimulation is an augmented input strategy that facilitates the expressive and receptive language skills of persons who require augmentative and alternative communication (AAC). The aim of this study was to determine and compare the acquisition of receptive vocabulary items during implementation of aided language stimulation with…

Discrete trial teaching (DTT) is a common teaching methodology used within intervention for autistics/individuals diagnosed with autism spectrum disorder (ASD). Practice recommendations related to using DTT for receptive language instruction includes the desired size of the array of stimuli to be presented. Some recommendations include ensuring…

Purpose: Manual sign is a common alternative mode of communication taught to children with childhood apraxia of speech (CAS). Gesture use is positively related to later increases in vocabulary and syntactic complexity in typical development, but there is little evidence supporting the use of manual sign for children with CAS. We sought to identify…

The ability to narrate past personal events is important for classroom participation and socio-emotional wellbeing. Although school-age children with Down syndrome show significant challenges producing personal event narratives, there is little research to guide personal narrative intervention. This study used a single subject experimental design…

Background: Pivotal response treatment (PRT) is suggested to be an effective treatment for children with autism spectrum disorder (ASD). Objectives: We aimed to compile evidence examining the effectiveness of PRT on social communication, social interaction, and repetitive behavior for children with ASD. Methods: We performed a systematic and…

Children with intellectual disabilities experience well-documented challenges in the development of problem-solving, particularly related to mathematical word-problem solving. Such challenges are related to both linguistic and conceptual skills. While interventions to assist children in developing conceptual skills are well reported, linguistic…

Young deaf and hard-of-hearing children enrolling in school in Sri Lanka often display language delay due to limited amplification and limited language stimulation. The scarcity of speech and language therapy support within the educational context at present necessitates a rethink of service-delivery models to reach more children. Multi-sensory…

Problem/Purpose: Young children with developmental speech and/or language impairment (DSLI) often fail to develop important oral language and early literacy skills that are foundational for subsequent schooling and reading success. The purpose of this investigation was to examine the efficacy of the TELL curriculum and associated evidence-based…

Research indicates the characteristics of Autism Spectrum Disorder include challenges with receptive and expressive language, which can negatively impact social-emotional development and physical regulation. The needs of children with autism are expected to greatly impact the current medical and educational resources, thus effective intervention…

Variability in clinical expression and in intervention outcome has been described in autism spectrum disorder (ASD). The study examined progress after 1 and 2 years of intervention and compared the impact of baseline cognitive ability on outcome trajectories in 46 children (m = 25.5 months) with ASD. The entire group showed a gradual decrease in…

This community effectiveness trial examined the feasibility and efficacy of a comprehensive psychosocial treatment for 28 children, aged 7 to 10 years with high-functioning autism spectrum disorders (HFASDs). Treatment included instruction and therapeutic activities targeting social skills, face-emotion recognition skills, interest expansion, and…

Purpose: We sought to identify factors predictive of or associated with receipt of speech/language services during early childhood. We did so by analyzing data from the Early Childhood Longitudinal Study-Birth Cohort (ECLS-B; Andreassen & Fletcher, 2005), a nationally representative dataset maintained by the U.S. Department of Education. We…

Background: This study evaluates the effects of a language and literacy intervention for children with Down syndrome. Methods: Teaching assistants (TAs) were trained to deliver a reading and language intervention to children in individual daily 40-min sessions. We used a waiting list control design, in which half the sample received the…
