Purpose: This tutorial summarizes current best practices in treating American English /r/ distortions in children with residual speech errors. Method: To enhance the effectiveness of clinicians' cueing and feedback, the phonetics of /r/ production is reviewed. Principles of acquisition, which can inform how to practice /r/ in the early stages of…

Young children who cannot use their natural speech to communicate their daily wants, needs, thoughts, and opinions often rely on augmentative and alternative communication (AAC) strategies that frequently use graphic symbols to assemble messages. Early intervention strategies typically focus on visual scene displays (VSDs) to place target messages…

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 article enters the debate about the complex and dynamical nature of second language acquisition (SLA) by discussing and commenting on Pallotti's critique of Complex Dynamic Systems Theory (CDST). Pallotti's critique brings to the fore the argument that, due to its anti-reductionist stance, CDST research fails to observe three fundamental…

In this article, first we obtained the correct mean square error expression of Gupta and Shabbir's linear weighted estimator of the ratio of two population proportions. Later we suggested the general class of ratio estimators of two population proportions. The usual ratio estimator, Wynn-type estimator, Singh, Singh, and Kaur difference-type…

The authors conducted three experiments examining the effect of grouping on children's generalization of animal labels. In Experiment 1 (N = 96), first graders (M age = 6 years, 10 months) who had seen a novel animal grouped with similar animals generalized its trained label more broadly than those who had seen it by itself or grouped with…

Purpose: An increasing number of anomia treatment studies have coupled traditional word retrieval accuracy outcome measures with more fine-grained analysis of word retrieval errors to allow for more comprehensive measurement of treatment-induced changes in word retrieval. The aim of this study was to examine changes in picture naming errors after…

This study aimed to determine whether attentional prioritization of stimuli associated with reward transfers across conceptual knowledge independently of physical features. Participants successively performed two color-word Stroop tasks. In the learning phase, neutral words were associated with high, low, or no monetary reward. In the…

A popular technology-based intervention is video-based instruction (VBI). VBI is known to be effective in teaching various skills to individuals with intellectual disability. Although many researchers have taught this population various skills using video modeling and/or prompting, none have conducted a literature review for this population. The…

Despite the call for an argument-based approach to validity over 25 years ago, few examples exist in the published literature. One possible explanation for this outcome is that the complexity of the argument-based approach makes implementation difficult. To counter this claim, we propose that the Assessment Triangle can serve as the overarching…

Recently it has been shown that rewarded variability can be used to adapt visuomotor behavior. However, its relevance seems limited because adaptation to binary rewards has been demonstrated only when the same movement is repeated throughout the experiment. We therefore investigated whether the adaptation is action-specific and whether the amount…

The literature suggests that children with autism spectrum disorder (ASD) educated in inclusive settings generally do not interact with typically developing classmates during social activities. This study assessed whether an intervention package consisting of interest-based structured play activities involving adult instruction, modeling, and…

Generalization and maintenance of intervention outcomes are of paramount importance in achieving socially significant outcomes within applied behavior analysis. Social skills interventions for young children with autism spectrum disorders (ASD) are widely represented within the empirical literature; however, generalization and maintenance outcomes…

Background: Cognitive-linguistic treatments and interventions targeting communication have been developed within the context of primary progressive aphasia (PPA), however knowledge about the scope of generalization and maintenance of therapy gains considering PPA subtypes remains scarce and awaits systematic investigation. Aims: To analyse the…

This review examined school-based social skills interventions for students with autism spectrum disorder who were educated in inclusive school settings. Secondary aims sought to explore observation protocols and the resulting social outcomes used to measure the social behaviors of students with autism spectrum disorder within authentic social…
