In peer-mediated intervention (PMI), peers act as agents of intervention. Previous reviews in this area have not addressed the effectiveness of using PMI with children with autism who are minimally verbal. Following a systematic search, we reviewed 25 studies where PMI was used to increase communication in minimally verbal participants. The…

This study examined the extent to which classroom quality (emotional and instructional climate) moderates the associations between teachers' beliefs about children, self-efficacy, and children's early language gains (receptive and expressive vocabulary). The study employed multilevel modeling with 606 preschool teachers and 2,536 preschool…

Background and aims: Nongenerative speech is the rote repetition of words or phrases heard from others or oneself. The most common manifestations of nongenerative speech are immediate and delayed echolalia, which are a well-attested clinical feature and a salient aspect of atypical language use in autism. However, there are no current estimates of…

Research has begun to investigate the reliability of cannabis-intoxicated eyewitnesses; however, no studies have evaluated eyewitness memory among chronic cannabis users after a minimum 24-h abstinence. This study compared cannabis users' (n = 23) and nonusers' (n = 26) eyewitness recall/identification and investigated the relationship between…

Cognitive abilities and interests both play an important role in guiding knowledge acquisition, but most previous studies have examined them separately. The current study used a large and representative dataset to integrate interests and abilities using a person-centered approach that examines how distinct profiles of interests and abilities…

We inquired whether introducing variability into a word-learning task would facilitate, inhibit, or have a neutral effect on adults' speech production and language learning. Twenty young adults from the U.S. Midwest with typical development participated. They repeated four novel words 10 times sequentially (blocked practice) and another four novel…

Background: Children's numerical and arithmetic skills differ greatly already at an early age. Although research focusing on accounting for these large individual differences clearly demonstrates that mathematical performance draws upon several cognitive abilities, our knowledge concerning key abilities underlying mathematical skill development is…

The present study examined how culture and gender influence the self-construal of mothers and their four-year-olds during dyadic reminiscing. Participants were 21 Thai (11 girls, 10 boys) and 21 American (10 girls, 11 boys) mother-child dyads. Thai dyads exhibited a more interdependent self-construal, whereas American dyads exhibited a more…

A cluster randomized design was used to investigate the effects of the "Story Friends" vocabulary curriculum on learning of 84 preschoolers in 24 classrooms who were at risk for language difficulties. Children in the treatment condition received explicit vocabulary instruction of 36 words during small-group storybook listening centers…

Because language-related skills in early childhood can predict reading and writing skills in school, as well as social engagement in adulthood, it is important to implement concrete actions to assist in the development of language skills among these children (Council of Ministers of Education, Canada [CMEC], 2021). Knowledge of existing research…

In this commentary on the Special Issue, I will address the question of what memory spans measure concerning language, as language has, at least, a linear and a hierarchical dimension. I suggest that if anything what is measured has to do with the linear dimension. Then, I will discuss the welcome results on bilingual children with language…

Pearson now uses a technology-based testing platform, Q-Interactive, to administer tests previously available in paper versions. The same norms are used for both versions; Pearson's in-house equivalency studies indicated that both versions are equated. The goal of the current study is to independently evaluate equivalency findings. For the current…

Language abilities in early childhood show stability over time and play an important role in the development of other cognitive processes. Identifying modifiable environmental risk factors is important to informing prevention and early intervention efforts. Maternal verbal ability has been previously linked to child verbal ability. The current…

During preschool age, three precursors to self-regulated learning (SRL) can be identified: general self-regulation ability, speech competence, and executive functioning. There is evidence for a large interindividual heterogeneity in these precursors which may have an impact on the development of SRL. This study (a) examined heterogeneity in SRL…

There is increasing literature showing that the presentation of Autism Spectrum Disorder (ASD) could be different according to the sex of the patient. Through the analysis of the Autism Diagnostic Interview Revised interview results of a study group consisting of 56 preschool children diagnosed with ASD potential differences in the presentation of…
