This study examines whether, and how, multiple risks in early childhood are associated with an increased likelihood of a poor language or literacy outcome in early adolescence. Using data from 210 participants in the longitudinal Twins Early Developmental Study, we focus on the following risk factors at age 4: family risk, and poor language,…

Background & aims: Individuals with non- or minimally verbal autism (nvASD) are primarily characterized by a severe speech production deficit, with speech limited to no or only a few words by school age. Significant unclarity remains over variability in language profiles across the lifespan, the nature of the language impairment seen, and…

Education is central to the acquisition of knowledge, such as when children learn new concepts. It is unknown, however, whether educational differences impact not only what concepts children learn, but how those concepts come to be represented in semantic memory--a system that supports higher cognitive functions, such as creative thinking. Here we…

Although extensive research has focused on the perceptual abilities of second language (L2) learners, a significant gap persists in understanding how cognitive functions like phonological short-term memory (PSTM) and nonverbal intelligence (IQ) impact L2 speech perception. This study sets out to investigate the discrimination of L2 English…

This study provides evidence connecting two aspects of visual-orthographic skills (orthographic awareness and delayed copying) to the common variance shared by Chinese word reading and arithmetic calculation, as well as in identifying positional knowledge of numbers as a potential mediator of these connections in Chinese primary school students (N…

Many individuals with autism experience challenges using language in social contexts (i.e., pragmatic language). Characterizing and understanding pragmatic variability is important to inform intervention strategies and the etiology of communication challenges in autism; however, current manual coding-based methods are often time and labor…

The present study presents a meta-analysis of the relations between phonological processing abilities and different mathematics subskills. Using a random-effects model with 94 studies (135 unique samples, 826 effect sizes), the present meta-analysis revealed a significant general association between phonological processing and mathematics (average…

To explore the roles of character recognition, expressive vocabulary, and syntactic awareness in deaf and hard of hearing (DHH) students' reading fluency, 52 Chinese DHH students (mean age = 13.29 years) in elementary school participated in the present study. The results showed that character recognition, expressive vocabulary, and syntactic…

Skilled reading requires fast and accurate access to previously encountered words stored in memory. Yet, little research addresses skills that support such lexical access. Based on theoretical predictions, one skill that may support lexical access is orthographic knowledge. Thus, our goal was to investigate the relation between lexical access and…

This study characterized the rates of attention-deficit/hyperactivity disorder (ADHD) in adolescent and young adult males with fragile X syndrome (FXS) using a multi-method approach integrating a DSM-based parent interview (Children's Interview for Psychiatric Syndromes; P-ChIPS, Fristad et al., 1998) and a parent rating scale (Child Behavior…

Purpose: This study examined language group differences in English syntactic knowledge based on performance on a sentence repetition task. Method: Fourth and sixth grade students who were monolinguals (n = 30), early bilinguals (i.e., simultaneous; n = 27), or late bilinguals (i.e., sequential; n = 29) completed an English sentence repetition…

Multiplication and division are complex constructs for young children to understand. In this article, the authors explore young children's ability to visualise and make groups of objects before they had formally been introduced to multiplication and division. The results provide some valuable insights into students' early understandings of…

This study examined the persistent problem of practice that ELLs are not identified for gifted programs at the same rate as their native English-speaking peers. The purpose of this research study was to investigate the relationship among English language proficiency levels and general intellectual ability of English language learners for gifted…

Adaptive behavior is a critical metric for measuring outcomes in those with autism spectrum disorder (ASD). Executive function skills predict adaptive behavior in youth with ASD with average or higher IQ; however, no study has examined this relationship in ASD with lower IQ (IQ = 75). The current study evaluated whether executive function…

A qualitative case study research design was used to examine American female elementary students' perceptions about mathematics before and after participating in a math practices workshop designed specifically for females. The workshop sought to address perceived barriers to learning math by applying math concepts to real-life situations while…
