There is widespread evidence that children display a mutual exclusivity response upon encountering new words. Children displaying this behaviour will select a novel, name-unknown object in response to a novel label, rather than a familiar, name-known object. The mutual exclusivity response has been viewed as a means of fast-mapping…

This meta-analysis examined the relationship between prenatal maternal stress and/or anxiety and the outcomes of children aged 3 months to 9 years. Of the 8754 studies published before June 2021 that were synthesized, 17 conducted in Western countries were included in the meta-analysis (N[subscript total] = 23,307; M[subscript males] 54%;…

Prior research has revealed robust and consistent relations between spatial and mathematical skills. Yet, establishing a causal relation has been met with mixed effects. To better understand whether, to what extent, and under what conditions mathematics performance can be improved through spatial training, we conducted a systematic meta-analysis…

Purpose: Developmental dyslexia is a specific learning disorder that affects 5-17% children, and persists into adulthood. Speech perception in noise (SPIN) ability in dyslexia has been largely examined in previous studies. However, the available literature remains controversial and it is unclear under which conditions the deficits occur. The…

This meta-analysis reviews the literature on communication modes, communicative functions, and AAC type examined during interventions with school-age participants with ASD and/or ID who experience CCN. Considering potential differences related to outcomes taught could help identify the most effective means of individualizing AAC interventions. We…

Statistical learning is a key concept in our understanding of language acquisition. Ample work has highlighted its role in numerous linguistic functions--yet statistical learning is not a unitary construct, and its consistency across different language properties remains unclear. In a meta-analysis of auditory-linguistic statistical learning…

Purpose: The purpose of this study is to identify predictors of treatment outcomes in Rapid Syllable Transition Treatment (ReST) for childhood apraxia of speech through an individual participant data meta-analysis. Method: A systematic literature search identified nine ReST studies for inclusion. Individual participant data were obtained, and…

This meta-analysis reviews the literature on communication modes, communicative functions, and AAC type examined during interventions with school-age participants with ASD and/or ID who experience CCN. Considering potential differences related to outcomes taught could help identify the most effective means of individualizing AAC interventions. We…

This meta-analytic review demonstrates that language interventions can improve oral language in children with neurodevelopmental disorders. We assessed interventions that target language skills in children with neurodevelopmental disorders. The interventions had to use techniques ranging from explicit and structured activities (explicit…

Which domain-specific self-evaluations are most central to children's global self-worth? And does this differ between countries with different levels of collectivism-individualism? We conducted a preregistered cross-cultural meta-analysis to address these questions. We included 141 independent samples (21 countries/regions, 584 cross-sectional…

Background: Although children with intellectual disabilities (ID) are at greater risk of falls from poorer balance ability than typically developing children, reliable information about which types of physical intervention are most effective is scarce. Objective: A meta-analysis was used to examine the most effective programs on balance ability in…

Purpose: The purpose of this study was to investigate whether there are elevated symptoms of anxiety or depression in children and adolescents (aged 2-18 years) who stutter, and to identify potential moderators of increased symptom severity. Method: We conducted a preregistered systematic review of databases and gray literature; 13 articles met…

We compared the Wechsler scores of individuals with twice-exceptionality (2e) and giftedness using a three-level Bayesian meta-analysis. Ninety-five effect sizes were calculated from 15 studies (n = 2,106). Results show that individuals with 2e who have learning disabilities perform lower than individuals with giftedness in Full-Scale Intelligence…

This meta-analysis examines the inconsistent findings across experimental studies that compared children's learning outcomes with digital and paper books. We quantitatively reviewed 39 studies reported in 30 articles (n = 1,812 children) and compared children's story comprehension and vocabulary learning in relation to medium (reading on paper…

Previous meta-analyses highlight the role of executive functions (EF), encompassing working memory, task-switching, and inhibition, in reading comprehension, but have not demarcated its role in decoding, defined as use of orthographic patterns to access oral pronunciations. According to the dual-route model, decoding involves parallel activation…
