Verb-marking errors such as "she play football" and "daddy singing" are a hallmark feature of English-speaking children's speech. We investigated the proposal that these errors are input-driven errors of commission arising from the high relative frequency of subject + unmarked verb sequences in well-formed child-directed…

Purpose: Although conversational recast treatment is generally efficacious, there are many ways in which the individual components of the treatment can be delivered. Some of these are known to enhance treatment, others appear to interfere with learning, and still others appear to have no impact at all. This study tests the potential effect of…

Paradigms with conflicting data patterns can be difficult to learn, resulting in acquisition error. In this dissertation, I look at how paradigms are reanalyzed over time to gain insight into the factors that influence morphophonological learning. Existing models of morphophonology (e.g. Hare & Elman 1995; Albright 2002b,a, 2010) predict…

School-age English learners (ELs) are faced with the challenging task of acquiring a foreign language while simultaneously reading academically demanding literature. Therefore, the current research aimed to examine the relation between the rate of grammatical tense marking errors made by ELs and their performance on measures of reading…

Purpose: The study examined the use of percent grammatical utterances (PGUs) for assessing grammatical skills in Mandarin-speaking 3-year-old children. Method: Participants were 30 Mandarin-speaking 3-year-olds with typical development. Language samples were collected in two visits for each child using a picture description task. Children were…

There is substantial evidence that children's apparent omission of grammatical morphemes in utterances such as "She play tennis" and "Mummy eating" is in fact errors of commission in which contextually licensed unmarked forms encountered in the input are reproduced in a context-blind fashion. So how do children stop making such…

Background & Aims: Narratives are regularly elicited as part of standardized assessments for autism spectrum conditions (ASC) such as the ADOS, but have rarely been utilized as linguistic data in their own right. We here aimed for a specific and comprehensive quantitative linguistic profile of such narratives across nominal, verbal, and…

This study explored potential biases in professional writing evaluation. An experiment was conducted in which individuals with hiring authority or influence at their workplace evaluated an email with multiple grammatical/typographical mistakes requesting that the reader make time to speak with the author. Participants were randomly assigned into…

This study aimed to analyze common syntactic errors found in the argumentative essays of third-year English major students at the Faculty of Foreign Languages, Van Lang University, Vietnam. Quantitative and qualitative methods were used to obtain data in this study. The quantitative approach involved counting and calculating the frequency,…

Subject-verb agreement errors are common in sentence production. Many studies have used experimental paradigms targeting the production of subject-verb agreement from a sentence preamble ("The key to the cabinets") and eliciting verb errors (… "*were shiny"). Through reanalysis of previous data (50 experiments; 102,369…

Purpose: Expressive language impairments are common among school-age boys with fragile X syndrome (FXS) and autistic boys. Given the high cooccurrence of autism spectrum disorder (ASD) among individuals with FXS, cross-condition comparisons can elucidate the specificity of such impairments as they relate to ASD. Language samples can provide…

This qualitative study investigates the errors committed by Turkish EFL learners and the rate of spelling mistakes to grammar errors in learners' paragraphs. In order to examine these issues, 19 participants studying at a private high school in Turkey took part in this study. The qualitative data were collected through students' paragraphs written…

School-aged English Learners (ELs) are faced with the challenging task of acquiring a foreign language while simultaneously reading academically demanding literature. Therefore, the current research aimed to examine the relation between the rate of grammatical tense marking errors made by ELs and their performance on measures of reading…

Across many language backgrounds, a consistent hurdle to accessing United States higher education is understanding the basic information necessary to apply for admission and financial aid and complete the many enrollment management processes necessary to begin one's college career (apply for housing, receive and submit vaccinations, register for…

Previous work has reported that children creatively make syntactic errors that are ungrammatical in their target language, but are grammatical in another language. One of the most well-known examples is "medial wh-question" errors in English-speaking children's wh-questions (e.g., "What do you think who the cat chased?" from…
