The purpose of this study was to investigate the role of variability in teaching prepositions to preschoolers with typical development (TD) and developmental language disorder (DLD). Input variability during teaching can enhance learning, but is target dependent. We hypothesized that high variability of objects would improve preposition learning.…

In this case study, situated in a preschool classroom within an early childhood Spanish/English dual language programme, we examine how an emergent bilingual child engages with multimodal resources to participate in sociodramatic play discourses. Guided by sociocultural and critical discourse perspectives on multimodality, we analysed ways in…

We investigated the effect of a morphological awareness intervention on the morphological awareness and reading skills of a 6-year-old student who was struggling with early reading skills and had a history of speech and language impairment. We conducted a 7-week intervention designed to increase the student's awareness of affixes and the meaning…

Variable language outcomes have been reported in children with the metabolic disorder galactosaemia (GAL), but these outcomes do not appear to be related to the severity of symptoms in the neonatal period, compliance with the non-dairy diet, or IQ. Currently, there is no means by which at-risk children with GAL can be identified early to initiate…

This systematic case study utilized a repeated acquisition design to investigate the impact of a caregiver-implemented RECALL (Reading to Engage Children with Autism in Language and Learning) on the correct, unprompted responses of a young child with autism spectrum disorder (ASD). RECALL is an adapted shared reading intervention that includes a…

The purpose of the current study is to document phonological change from a multidimensional perspective for a 3-year-old boy with phonological disorder by comparing three measures: (1) accuracy of consonant productions, (2) dynamic assessment, and (3) acoustic analysis. The methods included collecting a sample of the targets /s, [image omitted],…

Observational data collected in ecologically valid measurement contexts are likely to be influenced by contextual factors irrelevant to the research question. Using multiple sessions and raters often improves the stability of scores for variables from such contexts. Generalizability (G) theory can be used to give researchers important information…

A communicative repair has been defined as the ability to persist in communication and to modify, repeat, or revise a signal when the initial communication attempt failed. From an operant perspective, initial communicative acts and communicative repairs can be considered members of a response class in which each response produces the same outcome.…
