Purpose: The purpose of this study was to evaluate if higher quantity, diversity, and grammatical informativeness of verb phrases in parent follow-in utterances (i.e., utterances that mapped onto child attentional leads) were significantly related to later expressive verb vocabulary in children with autism spectrum disorder (ASD). Method: We…

Despite the importance of expressive language for individuals with autism spectrum disorder (ASD), expressive language assessments are not consistently included in ASD research and many studies do not adequately describe participants' verbal abilities. A valid and efficient measure of expressive language would facilitate consistent reporting…

Purpose: People with aphasia (PWA) use different kinds of gesture spontaneously when they communicate. Although there is evidence that the nature of the communicative task influences the linguistic performance of PWA, so far little is known about the influence of the communicative task on the production of gestures by PWA. We aimed to investigate…

Background: Children and adults with developmental disability frequently require either aided or unaided alternative and augmentative communication (AAC). Key word sign (KWS) involves using natural gesture and sign language to support the key words in spoken utterances. The purpose of this study was to determine whether communication partners of…

Purpose: This study aimed to provide detailed descriptive information about the speech of a heterogeneous cohort of children with autism spectrum disorder (ASD) and to explore whether subgroups exist based on this detailed speech data. High rates of delayed and disordered speech in both low-verbal and high-functioning children with ASD have been…

Purpose: This study investigated the production of tense and subject-verb agreement in Palestinian Arabic-speaking children with developmental language disorder (DLD) in comparison to their typically developing (TD) peers in terms of (a) performance accuracy and (b) error patterns. Method: Participants were 14 children with DLD aged 4;0-7;10 and…

Associative word learning, i.e., associating a word with an object, is an important building block of early word learning for TD infants. This study investigated the development of word-I object associations by TD infants and infants and toddlers with Williams syndrome (WS), a rare genetic disorder associated with delayed language and cognitive…

The traditional recommendation for sequencing speaker and listener instruction has been to teach listener skills prior to teaching speaker skills. In a review of the research literature prior to 2011, Petursdottir and Carr (2011) concluded that research did not support this recommendation. We reviewed the most recent research on the efficiency of…

Purpose: The aims of this study were (a) to assess the efficacy of the Vocabulary Acquisition and Usage for Late Talkers (VAULT) treatment and (b) to compare treatment outcomes for expressive vocabulary acquisition in late talkers in 2 conditions: 3 target words/90 doses per word per session versus 6 target words/45 doses per word per session.…

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…

In many autistic children, speech onset is delayed and expressive language emerges after 3 years of age. We qualitatively and quantitatively describe oral productions of autistic preschoolers, including many non- or minimally speaking, recorded during interactions with a caregiver and with an experimenter. Data clustering on manually coded oral…

Copying a text quickly and accurately is important both in school and in daily life. However, this skill has never been systematically studied, either in children with typical development (TD) or in children with specific learning disabilities (SLD). The aim of this research was to study the features of a copy task and its relationship with other…

The recent introduction of inclusive schooling settings in France has allowed children with autism spectrum disorder (ASD) as young as 3 years to benefit from teaching adapted to their special needs, while sharing the same educational environment as their typical peers. The present study examined (1) whether children with ASD attending an…

Self-assessment is an alternative assessment that can assess one's language ability, and it has been widely used, especially in classroom contexts. However, recent research has suggested different results regarding the correlation between student self-assessment and language performance. The accuracy of student assessment depends on various…

Purpose: Little is known about the specific nature of language abilities of autistic adolescents and young adults with language impairment (LI), limiting our knowledge of developmental trajectories and ability to develop efficacious speech/language supports. An important first step is establishing proof of concept of identification of LI in this…
