Adults are skilled at using language to construct/negotiate identity and to signal affiliation with others, but little is known about how these abilities develop in children. Clearly, children mirror statistical patterns in their local environment (e.g., Canadian children using "zed" instead of "zee"), but do they flexibly…

Scale errors are intriguing phenomena in which a child tries to perform an object-specific action on a tiny object. Several viewpoints explaining the developmental mechanisms underlying scale errors exist; however, there is no unified account of how different factors interact and affect scale errors, and the statistical approaches used in the…

Purpose: Language abilities have long been thought to be weaker in adults who stutter (AWS) compared to adults who do not stutter (AWNS). However, it is unknown whether modality affects language performance by AWS in time pressure situations. This study aimed to examine lexical access and retrieval abilities of AWS in oral and typed modes. Method:…

Chinese-English dual language learners (Chinese DLLs) are a growing population in the US. Existing studies of preschool-aged Chinese DLLs mostly focused on single-word vocabulary and rarely explored other skills important for school readiness. In the current study, we examined Chinese DLLs' development of receptive vocabulary and comprehension of…

Children's increasing expertise in composition relies partly on word choice. Little is known about how children consider words as they write, their meta-lexical awareness, or about their choice of words for writing. In this study, we investigate children's meta-lexical awareness, as one aspect of their metalinguistic awareness, which guides their…

Background: Core lexicon (CL) analysis is a time efficient and possibly reliable measure that captures discourse production abilities. For people with aphasia, CL scores have demonstrated correlations with aphasia severity, as well as other discourse and linguistic measures. It was also found to be clinician-friendly and clinically sensitive…

Purpose: The purpose of this study was to explore the relationship between speech perception, speech production, and vocabulary abilities in children with and without speech sound disorders (SSDs), analyzing the data both by group and continuously. Method: Sixty-one Australian English--speaking children aged 48-69 months participated in this…

Vocabulary is regarded as an important part of communicative language ability and a significant predictor of second language proficiency. The relation between vocabulary knowledge and communicative language ability has important implications for L2 students, foreign language teachers and educational systems. Thus, many studies have been conducted…

The study investigated how well Swedish adolescents recognize the meaning of derived words in English and whether this knowledge is determined by learner proficiency, word frequency, or affix type. Participants were 88 school students in two proficiency groups: 39 advanced 12th graders and 49 intermediate 9th graders. Two tests of receptive…

Middle school is one of the most important times during which students gain knowledge. However, a large proportion of adolescents have continued to complete middle school without mastering essential knowledge of, and skills in, vocabulary and reading comprehension. Adolescents who miss school in the 30-60 days leading up to high-stakes exams…

Background: Maternal input plays an important role in influencing linguistic development during the first years of life, and it is evident that mothers adapt their language according to their child's characteristics. Recently, it was demonstrated that maternal input addressed to children with sex chromosome trisomies (SCTs) at 8 months of age is…

Despite support for the importance of early language environments, little is known about the naturally occurring experiences children have in preschool settings. The current study sample included 91 children (M[subscript age] = 4.72 years; 56% male; 67% White) from 23 preschool classrooms and nearly 1500 h of language environment data from three…

As the United States continues to grow with English language learners entering schools, teachers must focus on helping them improve their reading comprehension. The problem addressed in this study was the lack of vocabulary instruction implemented by teachers impedes the development of English language learners' reading comprehension. The purpose…

Dyslexic children often fail to correct errors while reading aloud, and dyslexic adolescents and adults exhibit lower amplitudes of the error-related negativity (ERN)--the neural response to errors--than typical readers during silent reading. Past researchers therefore suggested that dyslexia may arise from a faulty error detection mechanism that…

Previous research on the effects of word-level factors on lexical acquisition has shown that frequency and concreteness are most important. Here, we investigate CDI data from 1,030 Dutch children, collected with the short form of the Dutch CDI, to address (i) how word-level factors predict lexical acquisition, once child-level factors are…
