Analysis of consistent Zearn Math users and a comparable group of non-users in District of Columbia Public Schools (DCPS) shows that students who used Zearn Math consistently had higher levels of academic growth than similar students with low- or no-usage. This analysis used two quasi-experimental methods, Coarsened Exact Matching (CEM) and fixed…

The purpose of this longitudinal investigation was to examine the effectiveness of a comprehensive, integrated curricular and co-curricular program designed to build community, provide academic and social support, and promote engagement in academically purposeful activities resulting in more equitable environments for historically…

Adolescents belonging to minority or marginalized groups often experience discrimination, which may negatively affect their mental and physical health. Using the dataset of the 2018 Health Behaviour in School-Aged Children (HBSC) study, we analyzed perceived discrimination based on various grounds in four minority groups of schoolchildren in…

We explored third- to fifth-grade children's friendship concepts in 20 autistic and 21 nonautistic students matched for mental age. Transcripts of semi-structured interviews were coded for definitions of friendship, friendship expectations, and friendship transgressions (i. e., violations of friendship expectations), and subjected to quantitative…

In the causal inference literature, evaluating blocking from a potential outcomes perspective has two main branches of work. The first focuses on larger blocks, with multiple treatment and control units in each block. The second focuses on matched pairs, with a single treatment and control unit in each block. These literatures not only provide…

Oral language abilities have been reported to be related to reading development. This relationship seems to be determined by orthographic systems and reading development. Children with developmental language disorder (DLD) show reading difficulties, although most studies focus on reading comprehension. The present study has two main objectives: to…

This study investigated bilingualism effects on the production of focus in 5- to 9-year-old Cantonese-English bilingual autistic children's L1 Cantonese, compared to their monolingual autistic peers as well as monolingual and bilingual typically developing children matched in nonverbal IQ, working memory, receptive vocabulary and maternal…

Understanding the nature of olfactory abnormalities is crucial for optimal interventions in children with autism spectrum disorders (ASD). However, previous studies that have investigated odor identification in children with ASD have produced inconsistent results. The ability to correctly identify an odor relies heavily on visual inputs in the…

Purpose: Cognition and language difficulties are frequently reported in both children and adults with epilepsy. The majority of the existing research has focused on pediatric epilepsy, documenting impairments in learning, academics, and social-emotional functioning. In comparison, language deficits in younger and older adults with epilepsy have…

Metabolic syndrome (MetS) is a growing epidemic related with higher values of blood pressure (BP) and autonomic dysfunction. Scientific evidence has been indicating that functional resistance training (FRT) is superior over conventional (CRT) for muscle fatigue and pain, yet its effects on autonomic modulation (AM), BP and heart rate in MetS are…

The current study examined cognitive effects of two pathways of second language (L2) acquisition longitudinally in Chinese speakers learning English in an L2-dominant environment. Thirty-nine participants who attended an intensive 10-week English course (L2-instruction group) were compared to 38 participants who attended regular university courses…

We consider situations in which public charter school lotteries are neither universally conducted nor consistently documented. Such lotteries produce "broken" Randomized Control Trials, but provide opportunities to assess the internal validity of quasi-experimental research designs. Here, we present the results of a statewide charter…

Despite much research examining whether bilingual individuals demonstrate superior executive function (EF) skills compared to monolinguals, the purported bilingual advantage remains controversial. One potential reason for discrepant findings across studies examining the bilingual advantage is the difficulty in matching monolingual and bilingual…

Children with autism often display discrepancies in their intellectual functioning, with nonverbal skills frequently being more developed than verbal. Compared to monolingual autistic children, however, much less is known about how bilingualism affects intelligence in autism. The current study examined the intelligence profiles of 146 bilingual…

Individuals with autism spectrum disorder (ASD) often exhibit disordered speech prosody, but sources of disordered prosody remain poorly understood. We explored patterns of temporal alignment and prosodic grouping in a speech-based metronome repetition task as well as manual coordination in a drum tapping task among Cantonese speakers with ASD and…
