Background: The implicit learning deficit hypothesis claims that impaired implicit learning underlies deficits in social-communicative abilities associated with developmental language disorder (DLD). However, previous research testing this hypothesis revealed inconsistent results and largely used process-impure sequential learning tasks. Aims:…

Executive function (EF), a set of neurocognitive processes, is central to students' emotional and behavioral well-being. Despite students with emotional and behavioral disorders (EBD) being at risk for negative long-term outcomes, there is a paucity of EF research with students at risk for EBD in early elementary school, an important…

We examined the development of 3 executive function (EF) components--inhibition, updating, and task shifting--over time in monolingual and bilingual school-age children. We tested 41 monolingual and 41 simultaneous bilingual typically developing children (ages 8-12) on nonverbal tasks measuring inhibition (the Flanker task), updating (the Corsi…

We assessed a range of theoretically critical predictors (numerosity discrimination, number knowledge, counting, language, executive function and finger gnosis) of early arithmetic development in a large unselected sample of 569 children at school entry. Assessments were repeated 12 months later. Although all predictors (except finger gnosis) were…

The importance of early vocabulary development to later reading comprehension has been well-established. However, there have been a number of criticisms that the assessments typically used to measure oral vocabulary knowledge do not adequately capture the complexity of this construct. This conceptual review works towards a more robust theoretical…

Research Findings Research suggests children from low-income environments have vocabularies that differ from those of their higher-income peers. They may have basic knowledge of many words of which children from higher income environments have acquired sub- or supra-ordinate knowledge. This study sought to determine if children from low-income…

Models of monolingual literacy propose that reading acquisition builds upon children's semantic, phonological, and orthographic knowledge. The relationships between these components vary cross-linguistically, yet it is generally unknown how these differences impact bilingual children's literacy. A comparison between Spanish-English bilingual and…

California's Kindergarten Readiness Act of 2010 revised the cutoff date by which children must turn five for kindergarten entry in that year and established transitional kindergarten (TK), defined as the first year of a two-year kindergarten program for all students affected by the birthdate eligibility change. Since it has been implemented across…

In the current study, we employed a concurrent multiple probe across participants design to examine the effects of an intervention package (i.e., response prompting, frames, technology) on sentence writing for three participants, ages 10-12, with intellectual and developmental disabilities (IDD). Specifically, we taught participants to write…

By the end of primary school, students are confronted with expository texts known for their high proportion of domain-specific academic vocabulary words. These words usually comprise Greek or Latin roots in their internal structure. Recent findings showed that knowledge of Greek and Latin roots is related to reading comprehension. However, no…

This two-year longitudinal study examined the role of linguistic interdependence between Spanish and English among a group of first, second, and third generation immigrant Spanish-English bilingual children. Starting from a theoretical perspective on linguistic interdependence that takes into account linguistic constructs and their measurement,…

Purpose: The goal was to determine whether interactive book reading outcomes for children with developmental language disorder (DLD) were affected by manipulation of dose (i.e., the number of exposures to the target word during a book reading session) and dose frequency (i.e., the number of repeated book reading sessions) and whether pretreatment…

This study examined accuracy on syllable-final (coda) consonants in newly-learned English-like nonwords to determine whether school-aged bilingual children may be more vulnerable to making errors on English-only codas than their monolingual, English-speaking peers, even at a stage in development when phonological accuracy in productions of…

Inference skill is one of the most important predictors of reading comprehension. Still, there is little rigorous research investigating the effects of inference instruction on reading comprehension. There is no research investigating the effects of inference instruction on reading comprehension for English learners with reading comprehension…

Reading comprehension is a complex task which depends on a range of cognitive and linguistic processes. According to the Simple View of Reading, this complexity can be captured as the product of two sets of skills: decoding and linguistic comprehension. The Simple View explains variance in reading comprehension and provides a good framework to…
