Purpose: The purpose of this study was to examine the effectiveness of an augmentative and alternative communication (AAC) intervention package consisting of systematic instruction and aided AAC modeling with speech-output technology on the acquisition, maintenance, and generalization of socio-communicative behaviors in four minimally speaking,…

Researchers have identified effective instructional strategies for teaching peer imitation, including embedded classroom-based interventions. However, there is a dearth of strategies that have been effective for teaching generalization of imitation skills to novel contexts. Building on previous research, we examined the use of progressive time…

Background and aims: This study was conducted in a clinical setting with the aim of replicating previously used procedures for teaching receptive vocabulary. Researchers increased the number of vocabulary words and maintained use of match-to-sample (MtS), prompting, and reinforcement procedures. Researchers were also interested in the efficacy of…

A multiple probe design across participants was used to evaluate the effectiveness of progressive time delay (PTD) during small group instruction to teach social problem-solving to preschoolers and to assess generalization to novel contexts. PTD was used to teach children to both name and use a variety of problem-solving solutions. Target…

Engagement in strong play skills is important as an outcome by itself, but also as means to achieve other valued outcomes in early childhood development. Yet, children with autism spectrum disorder (ASD) often demonstrate challenges in this area of development. To address these challenges, intervention is needed. This study evaluated the effects…

This study assessed the effects of portable video modeling on social interactions of four children with autism, three boys and one girl, 4- to 5-year-olds, in preschools in Iceland. Participants were shown 1-min videos on a small handheld device where a peer model initiated social interactions and played with two peers. A…

Research suggests peer imitation can be taught using systematic procedures and can be embedded into ongoing play contexts with preschool-age children. However, additional research is needed to test procedures that may increase levels of peer imitation with toddlers with disabilities and in generalized contexts. We used a multiple probe across…

We examined the use of an intervention package consisting of the system of least prompts (SLP), visual schedules, peer models, and contingent reinforcement to teach four children with disabilities to independently play board games and communicate with their typically developing peers. We found the intervention package with individual adaptations…

This RCT study examined efficacy of a preschool peer social intervention (PPSI) in facilitating social engagement of preschoolers with high-functioning ASD (HFASD; N = 65). HFASD participants were randomly assigned by preschool to a 6-month intervention (play, interaction, or conversation) or a waitlisted-treatment-as-usual control group. Trained…

This study examined the effects of a reading racetrack game on acquisition, maintenance, and generalization of sight words for four kindergarten students who are deaf. The game consisted of placing sight words around a racetrack board and prompting the participant to read the words. A multiple probe design across word sets demonstrated a…

Phonological awareness (PA) is defined as a child's ability to hear and manipulate parts of spoken language (National Early Literacy Panel [NELP], 2009; National Institute of Child Health and Human Development [NICHD], 2000). Ensuring that children develop PA increases the likelihood that they are successful with later reading instruction. Two…

In this study, researchers examine the impact of e-coaching (including a web-based professional development [PD] portal consisting of a learning module, self-monitoring, and video feedback) on preschool teachers' use of a simultaneous prompting (SP) procedure and the effects of SP on teaching discrete skills to their students with autism spectrum…

Parental involvement in intervention can support intervention efficacy, improve generalization, and increase accessibility. The Preschool Life Skills (PLS) program is designed to teach 13 preschool life skills and prevent problem behavior. The current study explores the utility of the PLS program as delivered by parents. In Experiment 1, 6 parents…

We conducted a meta-analysis of 22 video modeling intervention studies that included 49 preschool children diagnosed with autism spectrum disorders. Using the Nonoverlap of all pairs ("NAP"), an index of data overlap between phases in single-case research, we calculated effect size. Effect sizes for subgroups were also calculated. The…

Preschool children's use of decontextualized language, or talk about abstract topics beyond the here-and-now, is predictive of their kindergarten readiness and is associated with the frequency of parents' own use of decontextualized language. Does a brief, parent-focused intervention conveying the importance of decontextualized language cause…
