This study investigates the acquisition and maintenance of periphrastic and se-passives in second language (L2), heritage (HS), and (Spanish-dominant) native Spanish speakers (NS) by addressing: (i) How accessible are Spanish periphrastic passives (which also exist in English) and se-passives (unique to Spanish) for L2ers and HSs in production?…

The importance of fostering in students the requisite language to understand what is being communicated and how to communicate their understanding requires educators to conceptualize themselves as teachers of language and content. It is possible to engage in activities of the mathematics classroom and through that participation engage in language…

There is a well-documented association between developmental language disorder (DLD) and executive function (EF) deficits. These co-occurring deficits pose risks to students' short- and long-term academic and social outcomes. In the United States, school-based speech-language pathologists (SLPs) are tasked to ensure that students with DLD are able…

Intentional communication is a correlate of later language in children with autism spectrum disorder (ASD). A meta-analysis on two pragmatic functions of intentional communication acts (ICAs) suggested that declarative ICAs (used to comment) are correlated with language skills, but did not provide clear evidence regarding the association of…

The current study investigated the nature of second language (L2) learning influence on first language (L1) production and perception by systematically examining several L1 and L2 related factors (L1:L2 relative dominance, L2 production and perception acuity, and learning context) and their effect on L1 change. It is the first of its kind in…

In language learning, aided language modeling refers to the method by which communication partners provide models of the communication system used by individuals with complex communication repertoires that involving both symbols and speech. Providing aided language models creates opportunities for individuals with complex communication repertoires…

Previous research by Williams, Siegel and Mazefsky (2018) investigated the relationship between verbal abilities and problem behaviors using data from the Autism Inpatient Collection (AIC). This research found a weak and inconsistent association between verbal abilities and problem behavior severity; however, adapting/coping scores were…

Generalization is the ability to apply regularities to novel instances, for example, correctly guessing that the plural for the novel English word 'wug' should be 'wugs'. Early language learners make overgeneralization errors like 'mouses', applying regularities beyond their attested uses. Theories concerned with the question of how learners learn…

An experimental crossover research design was utilized to investigate the effects of multimedia-enhanced instruction on the vocabulary acquisition of dual language learners in the early childhood age range. Sixteen 3-year-olds stratified by classroom and randomly assigned to condition participated in an eight-week intervention that incorporated…

In English as a lingua franca (ELF) communication, in which English is used as a common language among interlocutors of different first languages, successful communication often features communication strategies that enhance mutual understanding and relationship management. Although prior research suggests that including such strategies in English…

Twenty-two years ago, the National Reading Panel (2000) released a research synthesis of effective reading practices for classroom instruction. The first is phonemic awareness. The others are phonics, fluency, vocabulary, and comprehension. This study examined the connection of assessment for kindergarten through second-grade students in the…

It is well-documented that there is a strong relationship between vocabulary and reading comprehension in school-age children. Limited vocabulary knowledge can impact a student's reading achievement, as may be the case for school-age English Learners (ELs). This study aims to analyze the role of vocabulary in predicting reading comprehension…

This study compared between the roles of the socio-pragmatic and data-driven aspects of caregiver input in the vocabulary development of both Typically Developing (TD) Children and children with Autism Spectrum Disorders (ASD). The role of Joint Attention (JA) and Supported Joint Engagement (SJE) episode types, as well as Follow-In (FI) Comments,…

With the increasing prevalence of autism diagnoses, large percentage of diagnosed individuals with comorbid language difficulties, and negative effects of these difficulties on language development and overall functioning, research on language acquisition in children diagnosed with autism spectrum disorder is essential. The current study used data…

This thesis examines whether native, heritage, and L2 speakers of Spanish engage a morphological layer of representation in the processing of inflected words, and whether they do so with both regularly- and irregularly-inflected words. Also examined is whether this tendency towards compositional (i.e. morphological rule-based) processing is…
