The prevalence of late language emergence (LLE) in young children is high, comprising 10 to 20% of toddlers. Late language emergence refers to children who do not use at least 50 single words and 2-word phrases at the age of two. Current best practices for the under-three population with or at risk of having disabilities include the use of…

Background: Drawing on the family stress model (Conger and Donnellan in Ann Rev Psychol 58:175-199, 2007. https://doi.org/10.1146/annurev.psych.58.110405.085551), parenting programs typically support caregivers' nurturing and cognitively stimulating practices to mitigate the effects of poverty on child development, with small-to-moderate…

This article puts forward several proposals for replicating two well-known "First Exposure" studies dealing with the earliest stages of adult second language acquisition. Both of them enquire into the word-level knowledge that complete beginners are able to extract from minimal input when exposed to a new language for the first time.…

The purpose of the study was to examine word learning in preschool children from families who differed in socioeconomic status (SES). Preschool children (N = 58) were assigned to SES groups based on maternal education and completed a dynamic assessment of explicit word learning 2 times. At the first administration, no SES-group differences were…

Children with multiple disabilities may experience significant disabilities in two or more areas of functioning including vision, motor, hearing, and communication such that they face limitations in social interactions throughout their daily lives (Bruce & Ivy, 2017). Many children have complex communication needs and evidence indicates that…

This paper describes a new automated disengagement tracking system (DTS) that detects learners' maladaptive behaviors, e.g. mind-wandering and impetuous responding, in an intelligent tutoring system (ITS), called AutoTutor. AutoTutor is a conversation-based intelligent tutoring system designed to help adult literacy learners improve their reading…

Purpose: Parent engagement is a critical component of optimizing services for young children with disabilities, including those with language disorders. Without training, however, many parents may lack the knowledge and skills to effectively facilitate their children's language development during the essential early childhood years. The Parents…

The goal of this study was to describe how underlying vocabulary knowledge manifests into vocabulary usage, and in turn, how usage predicts writing quality among adult basic education (ABE) learners. ABE learners were administered tasks that measured vocabulary knowledge, in the forms of both vocabulary breadth and depth. Participants were also…

It is widely recognized that language acquisition is one of the key elements that can boost migrants' and refugees' social inclusion, although some research has stressed that the mastery of language can be intended as a necessary but not a sufficient condition in the process of integration. This contribution aims at shaping further analysis on the…

Hu and Nation's (2000) study, which stipulated that second language (L2) readers need to be familiar with 98% of lexical items for adequate text comprehension, has become highly influential in L2 vocabulary research and pedagogy. However, the 98% critical threshold figure is based on findings from a research project in which a regression analysis…

Interventions focused on the home language environment have been shown to improve a number of child language outcomes in the first years of life. However, data on the longer-term effects of the intervention are still somewhat limited. The current study examines child vocabulary and complex speech outcomes (N = 59) during the year following…

During early childhood, economically disadvantaged children can experience challenges that affect their social-emotional, language, and physical health development across the lifespan. Psychologists have tested several interventions to address developmental problems during early childhood, but information about the degree to which economically…

This quantitative study was based on a parental intervention focused on children's language development. The Test de Vocabulario de Imagenes Peabody-III was used to assess children's vocabulary in Spanish pre- and post-intervention. The data was collected during five semesters from Fall 2015 to Fall 2017 from 421 economically-disadvantaged urban…

Phonological awareness relates closely to listening and speaking skills. It also has an important role in learning to read in an alphabetic writing system. In the context of learning a new language, it is essential to figure out an appropriate strategy in accelerating the phonological awareness skill. The present study aims at investigating the…

Lexical ability, an umbrella term to cover various knowledge and skills pertaining to words in print, is a key component in reading comprehension. Little is known how different facets of lexical ability jointly contribute to L2 reading comprehension and how the contributions may differ between higher- and lower-proficiency L2 learners. This study,…
