Developmental science has increasingly scrutinized how environmental hazards influence child outcomes, but few studies examine how contaminants affect disparities in early skill formation. Linking research on environmental inequality and early childhood development, this study assessed whether differences in exposure to neurotoxic lead explain…

Given their easy accessibility and dual-channel model of content presentation, instructional videos have become a favoured tool for EFL vocabulary learning tool among many students. Teachers often use various nonverbal behaviours to elicit social reactions and guide learners' attention in instructional videos. The current study conducted three…

Real-time attention coordination in parent-toddler dyads is often studied in tightly controlled laboratory settings. These studies have demonstrated the importance of joint attention in scaffolding the development of attention and the types of dyadic behaviors that support early language learning. Little is known about how often these behaviors…

Background & Aims: Many young children with autism spectrum disorder (ASD) demonstrate striking delays in early vocabulary development. Experimental studies that teach the meanings of novel nonwords can determine the effects of linguistic and attentional factors. One factor that may affect novel referent selection in children with ASD is…

This study intended to examine L2 young learners' vocabulary learning (i.e. form, meaning, and use). The research design involved a 2 (advance-organizer strategy: present vs. absent) × 4 (caption type: glossed full captions, glossed keyword captions, full captions, keyword captions) between-subjects design. A total of 240 Chinese ESL primary…

Purpose: The current study compared the effects of direct instruction versus indirect exposure on multiple aspects of novel word learning for children with developmental language disorder (DLD) and children with typical language development (TLD). Method: Participants included 36 children with DLD and 45 children with TLD. All children were in the…

A solid understanding of fractions is the cornerstone for acquiring proficiency with rational numbers and paves the way for learning advanced mathematical concepts, such as algebra. Fraction difficulties limit not only students' educational and vocational opportunities but also their ability to solve everyday problems. Students who exit 6th grade…

Vocabulary differences early in development are highly predictive of later language learning as well as achievement in school. Early word learning emerges in the context of tightly coupled social interactions between the early learner and a mature partner. In the present study, we develop and apply a novel paradigm--dual head-mounted eye…

This study investigates how learners use a freely available web-based multimodal language learning environment based on videos and newspaper articles with corresponding exercises and learning support in the form of help options, "NedBox," for learning L2 Dutch. In order to measure learners' use, a combination of eye movement and screen…

The aim of this research is to determine the attitudes of elementary school 4th graders regarding electronic books developed through innovative technologies in the development of vocabulary. Qualitative research methods were used in accordance with the purpose of the research. The data of the research were collected by the semi-structured…

Few studies have explored the learning opportunities different audiovisual genres may create for vocabulary learning. Even fewer have looked at how learners' viewing experience is affected by individual differences (IDs) in vocabulary size, attention, inhibition, or working memory. Such IDs have been shown to mediate early and long-term vocabulary…

The aim of the present study is to assess the relationship between the young child's attention in a word learning interactive context with the educators in nurseries during shared-book reading and child's subsequent vocabulary growth. The participants in the study were 24 infants from eight nurseries. Each infant was first observed during five…

Theory of mind has received intensive attention in research as an important skill to develop. Furthermore, recent evidence indicates its role in discourse comprehension. In the current study, we examined the mediating role of theory of mind in the relations of foundational language and cognitive skills (working memory, attentional control,…

Eye-tracking is primarily used as a tool to capture attentional processes in second language (L2) research. However, it is feasible to design visual displays that can react to and interact with eye-movements in technology-mediated contexts. We explored whether gaze-contingency can foster L2 development by drawing attention to novel words…

The current study examined the effect of speaker variability on children's cross-situational word learning (XSWL). The study also examined the role of bilingual experience and sustained attention. Forty English monolingual children and 40 Spanish-English bilingual children ages 4-7 completed a XSWL task in a Single Speaker Condition and a Multiple…
