UNASSIGNED: The present study evaluated the applicability of the sentence-focused framework to Mandarin-speaking children with cochlear implants (CIs) by examining the relative contribution of receptive/expressive noun and verb lexicon sizes to later grammatical complexity.
UNASSIGNED: Participants were 51 Mandarin-speaking children who received cochlear implantation before 30 months of age. At 12 months after CI activation, parents were asked to endorse words that their child could understand only or understand and say using the infant version of the Early Vocabulary Inventory. At 24 months after CI activation, parents were asked to endorse the grammatical structures that their children were able to say using the Grammatical Complexity subtest in the Mandarin Communicative Development Inventory-Taiwan. Children\'s receptive/expressive noun and verb lexicon sizes and grammatical complexity scores were computed from these parent checklists.
UNASSIGNED: Correlational analyses showed that children\'s receptive/expressive noun and verb lexicon sizes at 12 months after CI activation were all highly correlated with their grammatical complexity scores at 24 months after CI activation (ρs = .52-.63, ps < .001). Regression analyses further revealed that verb lexicon sizes at 12 months after CI activation outweighed noun lexicon sizes in accounting for grammatical complexity at 24 months after CI activation.
UNASSIGNED: Our findings supported the prediction of the sentence-focused framework. Emphasizing the role of verbs in early intervention has the potential to enhance grammatical outcomes in Mandarin-speaking children with CIs.

Objective: To investigate the features and influencing factors of language in children with various types of speech disorders. Methods: A case-control study was carried out, 262 children with speech disorder had been diagnosed at the language-speech clinic of the Center of Children\'s Healthcare, Children\'s Hospital, Capital Institute of Pediatrics from January 2021 to November 2023, the children with speech sound disorder as the speech sound disorder group, the children with developmental stuttering as the stuttering group. There were 100 typically-developed children who underwent physical checkups at the Center of Healthcare during the same period as the healthy group. All children experienced a standardized evaluation of language with diagnostic receptive and expressive assessment of mandarin-comprehensive(DREAM-C) and questionnaire, One-way ANOVA and LSD test were conducted to compare the differences in overall language, receptive language, expressive language, semantics, and syntax scores among 3 groups of children. According to the results of DREAM-C, the children with speech disorder were divided into language normal group and language delay group. Chi-square test and multivariate Logistic regression were implemented to analyze the association between the linguistic development of children with speech disorder and potential influential factors. Results: There were 145 children in the speech sound disorder group, including 110 males and 35 females respectively, with an age of (5.9±1.0) years; 117 children in the stuttering group, including 91 males and 26 females, with an age of (5.8±1.0) years; 100 children in the healthy group, including 75 males and 25 females, with an age of (5.7±1.2) years. The variations in overall language, expressive language, and syntax scores among 3 groups of children were statistically significant (92±18 vs.96±11 vs. 98±11, 81±18 vs. 84±14 vs. 88±13, 87±16 vs. 89±11 vs. 91±10, F=5.46, 4.69, 3.68, all P<0.05). Pairwise comparison revealed that the speech sound disorder group had lower scores in overall language, expressive language, and syntactic compared to the healthy group, and the differences were statistically significant (all P<0.01) and the overall language score was lower than that of children with stuttering (P<0.05). In terms of overall language and expressive language, there was a statistically significant difference in the incidence of language delay among the three groups of children (15.9% (23/145) vs. 20.5% (24/117) vs. 7.0% (7/100), 46.2% (67/145) vs. 39.3% (46/117) vs. 26.0% (26/100); χ2=7.93, 10.28; both P<0.05). In terms of overall language, the stuttering group took up the highest proportion. In terms of expressive language, the speech sound disorder group accounted for the highest amount. The incidence of language delay in children with speech disorder was 44.3% (116/262). Non-parent-child reading, daily screen time ≥1 hour and screen exposure before 1.5 years of age are risk factors for the development of language in children with speech disorder (OR=1.87, 2.18, 2.01; 95%CI 1.07-3.27, 1.23-3.86, 1.17-3.45; all P<0.01). Negative family history are protective factors for the progress of language ability (OR=0.37, 95%CI 0.17-0.81, P<0.05). Conclusions: Children with speech disorder tend to have easy access to language delay, especially in expressive language and syntax. The occurrence of language delay in children with speech disorder is tightly connected with factors such as the family medical history, parent-child reading, screen time, etc. Attention should be paid to the development of language in children who suffer from speech disorder.

We explored whether and to what extent the neural mechanisms of second language sentence processing resemble those of native speakers by investigating the temporal dynamics of syntactic processing in terms of active or passive voice in reading English sentences by Chinese English Foreign Language (EFL) learners with high or low English proficiency. Participants were divided into two groups based on their proficiency levels in English. Three types of sentences (active, passive and ungrammatical) were presented to participants when their event-related potential responses were recorded at the verbs and the final words. The results showed that high-proficiency participants exhibited a greater anterior negativity at the verb position for ungrammatical sentences compared to active sentences. Furthermore, passive sentences elicited a larger frontal positivity than active sentences at the final word position. Additionally, greater P600 effects were observed for both passive and ungrammatical sentences than active sentences at the final word. The low-proficiency group exhibited a greater anterior negativity at the verb (but not the final word) position. In conclusion, these findings emphasize the role of proficiency as a modulating factor in the processing of English active and passive sentences among Chinese EFL learners. Furthermore, the processing of English active and passive sentences by these learners can be conceptualized as a three-stage process: prediction, correction and integration, representing the underlying cognitive mechanisms. This study provides novel insights into the understanding of the cognitive mechanism involved in second language sentence processing.

As a representative form of discourse, oral narratives offer a sensitive, flexible, and ecologically valid tool for language evaluation. Nevertheless, oral narrative assessments in mainland China remain uncommon among school-age children. Therefore, this study explores the effectiveness of narrative microstructural assessment in Mandarin-speaking school-age children. Its primary purpose is to lay a foundation for future clinical applications by establishing a feasible administration procedure and validating various viable measures to facilitate the evaluation of language proficiencies.
Narrative samples were collected through a single wordless picture from 285 Mandarin-speaking children ages 7-12 years (Grades 1-6). The samples were then coded using a semiautomatic method for 22 individual measures at word, sentence, and discourse levels.
The adapted elicitation method was effective for all grades, with most of the children\'s stories exhibiting sufficient length, coherent structure, and certain self-fabricated specifics. The semiautomatic coding was also convenient and promising. Altogether, 19 measures were identified as robust predictors of grades, revealing a general tendency of grade-related increase from Grades 1 to 5. These measures exhibited three representative nonlinear trajectory patterns with varied rates of increase. Then, we developed a comprehensive composite measure through factor analysis, which combined six individual measures. The analysis verified the single factor of narrative microstructural competence and showed strong evidence of construct validity.
This study has provided a practical set of administration procedures, validated the efficacy of 19 individual measures as well as a composite measure, and offered corresponding field test data for clinical matching. The findings underscored the reliability and informative nature of oral narrative microstructural assessment in Mandarin-speaking school-age children.

The current study examined the role of vocabulary and grammar in the listening comprehension of school-age Cantonese-speaking children with developmental language disorder in Hong Kong. Participants were 692 typically developing children (TD) and 53 children with developmental language disorder (DLD) and they were tested with a standardized test of oral Cantonese, which includes measures on listening comprehension, receptive and expressive grammar, expressive vocabulary, word definition and lexical relations. The results from multiple regression analysis revealed that listening comprehension of the TD group was explained by receptive grammar, expressive vocabulary, and lexical relationships. However, children of the DLD group mainly relied on a subset of their vocabulary knowledge, as measured in a lexical relation task on antonym, in understanding the text under the constraint of a limited grammatical knowledge.

Current theories of nonword repetition (NWR) impairments for children with Developmental Language Disorder (DLD) are developed predominantly using data from Indo-European languages. Seldom have relevant theories been attested to the morph-syllabic language Mandarin Chinese. The present research aimed to explore the locus of NWR impairments for Mandarin children with DLD. 80 Mandarin-speaking children with typical development (TD) and 80 children with DLD were compared on nonword repetition accuracy and error types. It was a three-factor design with language groups (children with DLD vs. TD children) as the between-subjects factor, and components (onset, rhyme, and tone) and syllable numbers (one to four syllables) as the within-subjects factors. The analysis showed that both groups had less accuracy on the two phonological segments (onset and rhyme) relative to tone and showed more errors in multi-syllable nonwords. Children with DLD exhibited more noticeable errors in onsets and rhymes, although they did not display similar issues with tones compared to TD children. Repeated measures ANOVAs showed that children with DLD had pronounced errors in onsets, especially in repeating multi-syllable nonwords. Error type analysis revealed that children with DLD displayed more multiple than single errors in nonword repetition. The results support the \"segment-to-frame association\" theory, suggesting that Mandarin children with DLD are constrained in the concurrent mapping process between onsets, rhymes, and tones.

A prominent methodological issue in cognitive research on bilingualism is the lack of consistency in measuring second language (L2) proficiency. To reduce the inconsistency in L2 proficiency measurements, brief and valid vocabulary tests have been developed as an objective measure of proficiency in a variety of languages (e.g., English, French, Spanish). Here, we present LexCHI, a valid lexical test to measure Chinese proficiency. This freely available short test consists of 60 two-character items presented in simplified Chinese. Although it only takes a few minutes to complete LexCHI, the LexCHI scores in two studies correlated significantly with L2 participants\' performance in a translation task and a cloze test. We believe that LexCHI is a useful tool for researchers who need to objectively measure Chinese proficiency as part of their investigations.

This study investigated the comprehension and production of long passives (i.e. bei-constructions with an overt agent) in Mandarin-speaking children with developmental language disorder (DLD). Seventeen preschool children with DLD (1 female; mean age: 61 months old) and 23 typically developing (TD) children (6 females; mean age: 62 months old) participated in a sentence-picture matching task (for comprehension) and an elicited production task. Their nonverbal working memory (NVWM) was measured with the fourth edition of the Wechsler Preschool and Primary Scale of Intelligence. Results showed that children with DLD were less accurate and more likely to choose the picture with reversed thematic roles than their TD peers on passives in the sentence-picture matching task; in the elicited production task, they produced fewer target responses than TD children in passives. For NVWM, although that of the DLD group was lower than that of TD children, most children in the DLD group were within the average range. Furthermore, their performance on passives in the comprehension and production tasks was significantly correlated with their NVWM, which adds to the body of work suggesting links between complex syntax and working memory. However, the fact that NVWM could be preserved in the face of difficulties with passives suggests that this link may be due to NVWM enhancing performance during tasks with a high visual component, while it may not be underlyingly responsible for syntactic impairments in children with DLD.

Weak theory of mind (ToM) ability is a core deficit in children with autism. A growing body of work has found that there is a close relation between complement syntax and ToM in autistic children. However, researchers have not yet investigated whether other linguistic components may explain the difficulties in ToM reasoning in autistic children.
To determine whether verb factuality (i.e., mental and action verbs) is related to ToM ability, as measured by a false belief understanding (FBU) task after controlling the effect of complement syntax for Mandarin-speaking autistic children.
Participants were verbal autistic children, aged 4-7 years. Their IQ performance (verbal, performance and total IQ) and the comprehension of complement syntax were evaluated. A total of 38 children scoring over 9 points in complement syntax test and 90 points in the verbal IQ test were selected to complete verb factuality and FBU task. The χ2 tests and correlation analyses were carried out on two relations: (1) ToM ability and understanding of verb factuality; and (2) ToM ability and comprehension of complement syntax.
A total of 11 autistic children completed the action verb factuality task, while 14 completed the mental verb factuality task and 13 completed both tasks. Participants performed well on the verb factuality task, and their ToM performance appeared to be related to their linguistic ability, regardless of the type of verb (i.e., action or mental verb). However, complement syntax scores did not significantly predict the success of the FBU task for the autistic children.
The results of this study link weaker ToM ability with the understanding of verb factuality among autistic children aged 4-7 and provide new evidence for the view that the development of language facilitates improvement of ToM skills. The findings shed new light on how language affects or determines social interactions.
What is already known on the subject ToM ability is crucial for social interaction. It has been claimed that mental verb factuality (e.g., think, had thought) may play a role in the development of ToM reasoning in typically developing children, but whether there is a link between the mastery of verb factuality and ToM skills in autistic children is still unclear. What this study adds to existing knowledge Correlational analysis revealed links between verbal ToM measured by unexpected location task and factuality test of mental verbs as well as action verbs. More importantly, this study confirmed the extra role of verb factuality in explaining ToM ability after excluding the influence of the complement syntax. What are the potential or actual clinical implications of this work? This study suggests that the factuality of verbs could serve as a tool for autistic children to infer the mental states of others. Thus, training on this linguistic structure could be taken into consideration when improving the social skills of autistic children.

The Boston Naming Test (BNT) is the most widely used measure to assess anomia. However, it has been criticized for failing to differentiate the underlying cognitive process of anomia.
We validated the color-picture version of BNT (CP-BNT) in a sample with diverse neurodegenerative dementia diseases (NDDs). We also verified the differential ability of the composite indices of CP-BNT across NDDs groups.
The present study included Alzheimer\'s disease (n = 132), semantic variant primary progressive aphasia (svPPA, n = 53), non-svPPA (n = 33), posterior cortical atrophy (PCA, n = 35), and normal controls (n = 110). We evaluated psychometric properties of CP-BNT for the spontaneous naming (SN), the percentage of correct responses on semantic cuing and word recognition cuing (% SC, % WR). Receiver operating characteristic analysis was used to examine the discriminatory power of SN alone and the composite indices (SN, % SC, and % WR).
The CP-BNT had sufficient internal consistency, good convergent, divergent validity, and criterion validity. Different indices of CP-BNT demonstrated distinct cognitive underpinnings. Category fluency was the strongest predictor of SN (β= 0.46, p < 0.001). Auditory comprehension tests highly associated with % WR (Sentence comprehension: β= 0.22, p = 0.001; Word comprehension: β= 0.20, p = 0.001), whereas a lower visuospatial score predicted % SC (β= -0.2, p = 0.001). Composite indices had better predictability than the SN alone when differentiating between NDDs, especially for PCA versus non-svPPA (area under the curve increased from 63.9% to 81.2%).
The CP-BNT is a highly linguistically relevant test with sufficient reliability and validity. Composite indices could provide more differential information beyond SN and should be used in clinical practice.
