To account for natural variability in cognitive processing, it is standard practice to optimize a model's parameters by fitting it to behavioral data. Although most language-related theories acknowledge a large role for experience in language processing, variability reflecting that knowledge is usually ignored when evaluating a model's fit to…

Dual language learner children (DLLs) benefit from early childhood education (ECE) and learning multiple languages, but research has predominantly focused on English monolingual children, with limited insight on the ECE and early development of DLLs. This study investigated whether DLLs' developmental assets assessed at pre-k entry (i.e. English…

Given concerns about the reading achievement of Dual Language Learners (DLLs) in comparison to English Monolinguals (EMs), this study examined individual difference variables contributing to English reading comprehension growth in Spanish-speaking DLLs and their EM counterparts in Grades 1-4. The participants, who included 578 DLLs and 412 EMs,…

Further, in this study the authors also examined whether the…
