Previous research has investigated generalized intraverbal-tacting by teaching children with autism to respond using autoclitic frames. The present study compared the effectiveness and efficiency of a Frame and a No Frame procedure across counterbalanced stimulus sets with 4 children with autism. In the Frame condition, children were taught to…

Background and aims: Previous research into word learning in children with developmental language disorder (DLD) indicates that the learning of word forms and meanings, rather than form-referent links, is problematic. This difficulty appears to arise with impaired encoding, while retention of word knowledge remains intact. Evidence also suggests…

This study examines relationships between mathematical problem-solving performance (in terms of strategies used and accuracy) and the main cognitive domains associated with mathematical learning (i.e. executive functions, verbal comprehension and social perception) of children with and without autism spectrum disorder (ASD and non-ASD resp.). The…

Background: Vocabulary scores increase until approximately age 65 years and then remain stable or decrease slightly, unlike scores on tests of other cognitive abilities that decline significantly with age. Aims: To review the findings on ageing-related changes in vocabulary, and to discuss four methodological issues: research design; test type;…

Purpose: This study investigated articulatory patterns for American English /[Voiced alveolar approximant]/ in children with and without a history of residual speech sound disorder (RSSD). It was hypothesized that children without RSSD would favor bunched tongue shapes, similar to American adults reported in previous literature. Based on clinical…

Purpose: Individuals with proximal 16p11.2 copy number variants (CNVs), either deletions (16p11.2DS) or duplications (16p11.2Dup), are predisposed to neurodevelopmental difficulties and disorders, such as language disorders, intellectual disability, and autism spectrum disorder. The purpose of the current study was to characterize language…

Williams syndrome (WS) is a rare genetic syndrome. As with all rare syndromes, obtaining adequately powered sample sizes is a challenge. Here we present legacy data from seven UK labs, enabling the characterisation of cross-sectional and longitudinal developmental trajectories of verbal and non-verbal development in the largest sample of…

The study evaluated the convergent validity of the PEAK-E-PA and two common assessments of language development used in educational and clinical settings: the ABLLS-R and the TOLD-I:4. The PEAK-E-PA provides a measure of a participant's ability to derive arbitrary stimulus relations, and may therefore provide a more complex analysis of language…

The causes of aggressive behavior in children with autism are poorly understood, which limits treatment options. Therefore, this study used behavioral testing and parent reports of 60 children with autism to investigate the interplay of emotion misinterpretation and hostile attribution bias in the prediction of different aggressive behaviors.…

Computational thinking -- the ability to reformulate and solve problems in ways that can be undertaken by computers -- has been heralded as a foundational capability for the 21st Century. However, there are potentially different ways to conceptualise and measure computational thinking, for instance, as generalized problem solving capabilities or…

The changed sentence: The aim of this study was to investigate the reliability and validity of the Emotion Matching Task (EMT) in a sample of Croatian preschool children. The Croatian version of the EMT was applied to 198 children (52% female), together with measures of verbal ability and social competence. The internal structure of the test, as…

Purpose: Sign language, like spoken language, incorporates phonological and articulatory (or motor) processing components. Thus, the learning of novel signs, like novel spoken word forms, may be problematic for children with developmental language disorder (DLD). In the present work, we hypothesize that phonological and articulatory deficits in…

This research aimed to examine the views of preservice mathematics teachers (PMTs) on mathematically giftedness. Case study, one of the qualitative research design, was used and the study involved 25 sophomore mathematics teaching undergraduate students from Turkey. Data were collected with a semi-structured interview form with open-ended…

Objective: Verbal fluency evaluation in bilingual speakers should include dual-language assessment to obtain a comprehensive profile of word retrieval abilities. This study is the first to compare classic semantic, action, emotional, and phonemic fluency in terms of the magnitude of their performance gaps between the dominant and nondominant…

The purpose of this study is to provide content validity evidence for the Verbal Behavior Milestones Assessment and Placement Program (VB-MAPP). A national panel of 13 experts provided an evaluation of the domain relevance, age appropriateness, method of measurement appropriateness, and domain representation across the three levels of the…
