RESUMO

PURPOSE: This study aimed to analyse the relationship between the use of digital devices, family function, and language development in preschool children. METHODS: This cross-sectional, descriptive-correlational study included a sample of 93 parent-child dyads. The children were of an average age of 57.01 ± 9.95 months, and the majority were female. The data collection instruments included a questionnaire on the use of digital devices, the Portuguese version of the Family Flexibility and Cohesion Evaluation Scale - Version IV (FACES-IV), and a Preschool Language Test (TL-ALPE). RESULTS: The findings showed a greater tendency of children to use smartphones, tablets, and television for 0-3 hours daily. The analysis of the responses on the FACES-IV and TL-ALPE instruments showed that most of the participating families were of the balanced type and that most children had normal language development. Statistically significant relationships were found between the FACES-IV subscales and TL-ALPE subtests, FACES-IV subscales and the use of digital devices, and the use of digital devices and TL-ALPE subtests. Notably, children in more balanced family functioning scored higher on TL-ALPE tests, and the time spent using digital devices may compromise language development. CONCLUSION: This study highlights the impact of digital device use and the role of family functioning on children's language development, suggesting that moderate digital device use and balanced family functioning are facilitating factors for good language development.


OBJETIVO: Este estudo teve como objetivo analisar a relação entre a utilização de dispositivos digitais, o funcionamento familiar e o desenvolvimento da linguagem em crianças de idade pré-escolar. MÉTODO: Estudo transversal, descritivo-correlacional com uma amostra de 93 díades pais-crianças. As crianças tinham uma média etária de 57,01 ± 9,95 meses, sendo a maioria do gênero feminino. Os instrumentos de recolha de dados incluíram um questionário sobre o uso de dispositivos digitais, a versão portuguesa da Escala de Avaliação da Flexibilidade e Coesão Familiar - Versão IV (FACES-IV) e o Teste de Linguagem - Avaliação de Linguagem Pré-Escolar (TL-ALPE). RESULTADOS: As respostas demonstram uma maior tendência para a utilização do smartphone, tablet e televisão entre 0 e 3 horas por dia nas crianças. Com a aplicação da FACES-IV e do TL-ALPE, verificou-se que a maioria das famílias participantes eram do tipo equilibrado e que a maioria das crianças apresenta um normal desenvolvimento da linguagem. Observaram-se relações estatisticamente significativas entre a FACES-IV e o TL-ALPE; a FACES-IV e a utilização de dispositivos digitais; a utilização de dispositivos digitais e o TL-ALPE. Verificou-se que crianças com um funcionamento familiar mais equilibrado pontuam mais alto nas provas do TL-ALPE e que o tempo de uso de dispositivos digitais pode comprometer o desenvolvimento da linguagem. CONCLUSÃO: Destaca-se o impacto da utilização dos dispositivos digitais e o papel do funcionamento familiar no desenvolvimento da linguagem da criança, sugerindo que uma utilização moderada de dispositivos digitais e um funcionamento familiar equilibrado são fatores facilitadores de um bom desenvolvimento da linguagem.

RESUMO

INTRODUCTION: The quick aphasia battery (QAB), which assesses all areas of language in detail and quickly, was developed in English. It has been shown to be suitable for bedside patients. There is a need for a Turkish bedside test that allows for a comprehensive yet rapid assessment of stroke patients in terms of aphasia. The aim of this study was to create a Turkish version of QAB (QAB-TR) and to determine its validity and reliability in Turkish-speaking patients after a stroke. MATERIALS AND METHODS: The study was conducted with 188 people aged 41-88 years. Of these, 37 (19.7%) had aphasia (12 chronic, 25 acute), 53 (28.2%) were acute stroke patients without aphasia, and 98 (52.1%) were healthy controls. Internal consistency and criterion validity, test-retest reliability, and inter-rater reliability of the QAB-TR were performed. The language assessment test for aphasia was used for criterion validity. For the inter-rater reliability of the test, two different speech language therapists (SLP) administered the QAB-TR. For test-retest reliability, 2 weeks later, the same SLP who filled out the QAB-TR the first time was administered the test again. To test the validity of the test, correlations between the items and subsections were determined. Receiver operating characteristic (ROC) analysis was performed to examine the sensitivity and selectivity of the QAB-TR score, and a cut-off value was determined to distinguish patients with aphasia. RESULTS: The inter-rater Krippendorff's alpha value of the QAB-TR total was 0.6754. There was no statistically significant difference (p > .05) between the first and second QAB-TR total scores. The correlation analysis between the QAB-TR subsection scores and the total QAB-TR score (0.244-0.897) revealed statistically significant relationships. The area under the ROC curve was statistically significant and was found to be 0.853 (95% confidence interval: 0.799-0.906). The cut-off point for the QAB score to discriminate between patients with aphasia and those without aphasia was found to be 8.825, with 0.767 sensitivity and 0.765 selectivity (1-0.235). CONCLUSION: All the study results show that QAB-TR has internal consistency, criterion validity, test-retest reliability, and inter-rater reliability. It can be administered in as little as 15 min and provides information about the multidimensional linguistic profiles of individuals. QAB-TR can be used for both clinical and study purposes as a language battery that allows for the measurement of the strengths and weaknesses of Turkish-speaking individuals who have suffered a stroke in basic language areas in acute and chronic periods. It can be easily administered at the bedside for individuals who have just suffered an acute stroke and can facilitate early assessment of individuals in terms of aphasia and early initiation of therapy, if necessary.

RESUMO

This study investigated interactions among linguistics, social and political factors in a linguistically rich environment. For this purpose, two-hundred Iranian preschoolers (aged 5 to 6 years old) from four ethnic/linguistic groups (Arab, Kurd, Turk and Fars) were selected using multi-stage stratified sampling. All participants took part in an Elementary English language course and their exposure to foreground TV was recorded using media exposure portfolio. Maternal education and family income were considered as criteria for socio-economic status. Children's language proficiency was measured through Language Sample Analysis (LSA). The LSA components included total number of utterances produced, total number of words produced, total number of new words produced and mean length of utterances. Regression analysis, ANOVA and t-tests were used for data analyses. The results showed that bilingual children performed slightly better than multilingual children in LSA measures but this cannot be taken for granted. Moreover, socio-economic status and LSA measures were significantly related but TV exposure was not associated with the LSA measures. These results supported the arguments purported by minority language proponents on the importance of using children's mother tongue in educational curriculum.

RESUMO

Extent evidence has shown that morphosyntax is one of the most challenging linguistic areas for children with atypical early language experiences. Over the last couple of years, comparisons between deaf children with CIs and children with DLD have gained interest - as cases of atypical early language experiences, including, but not restricted to, delayed onset of exposure to language input and language-processing difficulties. Evidence suggests that the morphosyntactic difficulties experienced by deaf children with CIs and children with DLD are very similar in nature. However, the few studies that have directly compared both groups are inconclusive, with deaf children with CIs either performing significantly better or on par with children with DLD. These differences in findings can be attributed, in part at least, to a failure to implement essential methodological controls - even more so given that deaf children with CIs comprise a very diverse population. The goal of the present study was to directly compare the performance of deaf children with CIs to that of children with DLD on a morphosyntactic ability known to be particularly difficult for both groups. Specifically, the present study conducted a detailed examination of the past tense marking abilities of deaf children with CIs and children with DLD while controlling for factors specific to deaf children with CIs, for children's basic cognitive abilities as well as for children's age, sex assigned at birth, and SES. Past tense verbs are particularly relevant as they are used as a marker of developmental language disorder (DLD) in children learning French. Moreover, extent evidence shows that deaf children with CIs and children with DLD have important WM difficulties, but also that there is an association between auditory perception, processing abilities, and working memory (WM) abilities as well as with the acquisition of morphological features, including tense marking. Unfortunately, no study has examined the relation between the accurate production of past tense verbs and WM abilities in children with CIs and children with DLD learning French. Fifteen deaf children with CIs between 5 and 7 years of age were compared to 15 children with DLD and to 15 typically-developing monolingual controls (MON), matched on important variables, using a past tense elicitation task as well as measures of phonological and nonverbal WM abilities. The results confirm that the deaf children with CIs and the children with DLD both performed significantly lower than the MON controls on the past tense elicitation task - suggesting that difficulties with past tense verbs in French might not only be a marker of DLD but, instead, a correlate of atypical language acquisition. Of importance, the present study is the first to show that deaf children with CIs perform significantly lower than children with DLD on a past tense elicitation task - highlighting the importance of using methodological controls. As well, significant correlations were found between the performance of the deaf children with CIs and of the children with DLD on the past tense elicitation task and their phonological and nonverbal WM abilities. Taken together with previous studies conducted in the same populations, this represents another evidence suggesting that early atypical language experiences result in language and WM deficits, including morphosyntactic difficulties.

RESUMO

PURPOSE: We examined the properties of mean length of utterance (MLU) in Czech, a morphologically complex Slavic language. We compared the scores of MLU calculated in different units and based on different sample lengths and assessed its validity against another transcript and test-based measures. METHOD: One hundred nine children were recorded during free-play at 2;6 and 3;11 (years;months). We compared MLU in syllables, morphemes, and words (MLUw) in transcripts of different lengths (50, 75, 100, and all available utterances). For evaluating the validity of MLU, we also calculated Index of Productive Syntax (IPSyn) and number of different words (NDW) and used results of receptive vocabulary and grammar comprehension tests. RESULTS: The different MLU measures based on different sample lengths correlated closely with MLU in transcripts of all utterances (all rs > .87). We found mostly strong correlations between MLU, IPSyn, and NDW at both time points and weak or moderate correlations between MLU and grammar and vocabulary. Regression models showed the significant unique effect of MLUw at 2;6 for MLUw (ß = .29) and grammar (ß = .33) at 3;11 and vocabulary (ß = .27) at 3;7. CONCLUSION: MLUw based on all utterances was confirmed as a valid measure of early language skills in Czech, as it is stable in time and shows concurrent and predictive relations with other transcript-based and test-based measures.

RESUMO

PURPOSE: Naturalistic-developmental-behavioral interventions (NDBIs) are a widely accepted and validated approach for treating language-related symptoms in autism spectrum disorder, including deficits in vocabulary, social skills, and grammar. The purpose of this article is to define the elements naturalistic, developmental, and behavioral as applied to children with developmental language disorder (DLD) and to provide an example of how this type of intervention can be implemented to teach vocabulary and test cross-modal generalization between expressive and receptive modalities. METHOD: A vocabulary intervention using hybrid NDBI methods (storybook reading and conversational recast interaction) was provided to three participants with DLD using a single-case design. RESULTS: The results indicated that all participants successfully learned receptive and expressive vocabulary targets with extensive cross-modal generalization. However, generalization was limited in some of the participants. CONCLUSIONS: This article provided definitions of key elements of NDBI (naturalistic, developmental, and behavioral) including a rationale for extending NDBI procedures to language intervention for children with DLD. In addition, a single-case design demonstrated that NDBI can be implemented in DLD and that broadly defined naturalistic-developmental applied behavior analysis techniques are applicable to language interventions for children with language disorders. Moreover, diverse naturalistic and developmental procedures meet the highest standards for evidence-based practice to treat DLD.

RESUMO

BACKGROUND: Individuals with amnestic mild cognitive impairment (aMCI), especially for those with multidomain cognitive deficits, should be clinically examined for determining risk of developing Alzheimer's disease. English-speakers with aMCI exhibit language impairments mostly at the lexical-semantic level. Given that the language processing of Mandarin Chinese is different from that of alphabetic languages, whether previous findings for English-speakers with aMCI can be generalized to Mandarin Chinese speakers with aMCI remains unclear. OBJECTIVE: This study examined the multifaceted language functions of Mandarin Chinese speakers with aMCI and compared them with those without cognitive impairment by using a newly developed language test battery. METHODS: Twenty-three individuals with aMCI and 29 individuals without cognitive impairment were recruited. The new language test battery comprises five language domains (oral production, auditory and reading comprehension, reading aloud, repetition, and writing). RESULTS: Compared with the controls, the individuals with aMCI exhibited poorer performance in the oral production and auditory and reading comprehension domains, especially on tests involving effortful lexical and semantic processing. Moreover, the aMCI group made more semantic naming errors compared with their counterparts and tended to experience difficulty in processing items belonging to the categories of living objects. CONCLUSIONS: The pattern identified in the present study is similar to that of English-speaking individuals with aMCI across multiple language domains. Incorporating language tests involving lexical and semantic processing into clinical practice is essential and can help identify early language dysfunction in Mandarin Chinese speakers with aMCI.

RESUMO

PURPOSE: The purpose of this study is to determine if 2.5-year-olds with language delay would learn verbs (spill) when presented with varying syntactic structure ("The woman is spilling the milk"/"The milk is spilling"; milk = patient or theme) in a therapeutic context. Children with language delay have proportionally small inventories of verbs, which limits expressive language development. Children who have typical language development learn verbs more robustly when presented with alternating arguments than with a single argument structure. METHOD: Three toddlers with expressive language delay (29-30 months of age) participated in a verb-focused treatment study using a concurrent multiple baseline design. Participants were shown action videos accompanied by sentences with varied argument structure for each target verb. To assess learning pre- and posttreatment, participants were asked to demonstrate actions corresponding to each verb. RESULTS: Visual inspection and tau analyses reveal significant posttreatment gains of target verbs taught with varying argument structures. CONCLUSIONS: Our results indicate that learning verbs with high variability of argument roles may facilitate a strong link between lexical representations of verbs and their syntactic structures. Using argument structure variability to teach verbs as an intervention strategy has great potential and should be tested further in larger group studies.

RESUMO

Anecdotal evidence suggests that learning a new foreign language (FL) makes you forget previously learned FLs. To seek empirical evidence for this claim, we tested whether learning words in a previously unknown L3 hampers subsequent retrieval of their L2 translation equivalents. In two experiments, Dutch native speakers with knowledge of English (L2), but not Spanish (L3), first completed an English vocabulary test, based on which 46 participant-specific, known English words were chosen. Half of those were then learned in Spanish. Finally, participants' memory for all 46 English words was probed again in a picture naming task. In Experiment 1, all tests took place within one session. In Experiment 2, we separated the English pre-test from Spanish learning by a day and manipulated the timing of the English post-test (immediately after learning vs. 1 day later). By separating the post-test from Spanish learning, we asked whether consolidation of the new Spanish words would increase their interference strength. We found significant main effects of interference in naming latencies and accuracy: Participants speeded up less and were less accurate to recall words in English for which they had learned Spanish translations, compared with words for which they had not. Consolidation time did not significantly affect these interference effects. Thus, learning a new language indeed comes at the cost of subsequent retrieval ability in other FLs. Such interference effects set in immediately after learning and do not need time to emerge, even when the other FL has been known for a long time.

RESUMO

BACKGROUND: Speech and language skills are important for social interaction and learning. This study characterised the communication abilities of verbal individuals with SOX11 syndrome using a standardised parent/carer questionnaire, the Children's Communication Checklist (CCC-2). METHOD: Thirteen parent/carers of verbal individuals (aged 5-19 years) diagnosed with SOX11 syndrome completed the CCC-2. In order to contextualise findings, responses were compared to norms and to data from Noonan syndrome, a relatively well-known genetic diagnosis associated with communication impairment. RESULTS: For all individuals, the CCC-2 composite score indicated significant communication difficulties. Language structure (speech, syntax, semantics and coherence), pragmatic language (inappropriate initiation, stereotyped language use of context and non-verbal communication) and autistic features (social relations and interests) scores were lower than typically developing norms. Subscale comparisons revealed relative difference in use of context compared to other pragmatic domains (stereotyped language and inappropriate initiation). Individual scores showed substantial variation, particularly in regard to language structure profile. Differences were more pronounced than for Noonan syndrome, specifically in domains of speech, syntax, non-verbal communication and social relations. CONCLUSIONS: SOX11 syndrome is associated with communication impairment. It is important to assess communication abilities as part of the management of individuals with SOX11 syndrome and understand individual strengths and difficulties in order to provide targeted support.

RESUMO

PURPOSE: This study evaluates three different language sample elicitation strategies to determine a valid elicitation strategy for early language learners who speak using augmentative and alternative communication (AAC). METHOD: Ten children who speak using AAC participated in this study. Language samples were elicited from each participant using three strategies: the Communication and Symbolic Behavior Scales (CSBS), a generic play-based elicitation strategy, and automatic data logging. Samples were transcribed and coded. Additionally, each participant's school speech-language pathologist completed a Communication Matrix. Data from coded language samples were correlated with Communication Matrix results to determine the elicitation strategy that yielded the most valid language sample in comparison to Communication Matrix results. RESULTS: Both the CSBS and the play-based strategy yielded clinically relevant information. Because the log lacked communicative context, resulting data from the log was limited. An analysis of variance revealed significant differences in the amount of information elicited from each elicitation strategy. The CSBS repeatedly elicited the most data, followed by the play-based strategy and then the log. Generic play-based strategy results yielded the most correlations with Communication Matrix data. CONCLUSIONS: This preliminary data suggest that the play-based elicitation strategy elicited the most valid language sample when compared to the Communication Matrix from early language learners who speak using AAC. Additionally, results suggest that the CSBS may be an effective tool to measure the limits of this population's expressive language abilities.

RESUMO

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.

RESUMO

BACKGROUND: Developmental language disorder (DLD) affects the ability to acquire and make use of native language. Possible underlying cognitive mechanisms are related to memory functions. AIMS: The aim was examination of the relationship between visual short-term memory of objects as well as audiovisual short-term memory, and particular nonverbal and language abilities. METHODS AND PROCEDURES: The study included 7-9-year-old children with DLD and matched control group. Participants completed the Language Development Test, the Stanford-Binet IQ scale (SB5), and two short-term memory tasks: immediate recall of the visually presented pictograms and immediate recall of audiovisually presented sequences of syllables. OUTCOMES AND RESULTS: The results revealed diminished levels of short-term visual memory for objects as well as audiovisual memory in children with DLD. However, there were no group differences in the control task of WM. CONCLUSIONS AND IMPLICATIONS: Results supported the idea of diminished abilities in children with DLD to perform mental operations on verbalizable visual objects. Importantly non-verbal working memory ability, which cannot easily be supported by verbal representations, is at typical levels. This suggests that verbalization ability should be taken into account in the assessment of seemingly non-verbal cognitive functions among children with DLD.

RESUMO

OBJECTIVE: Although language is often considered to be largely intact in multiple sclerosis (MS), word-finding difficulties are a common complaint. Recent work suggests that declines in language are not solely the result of motoric and cognitive slowing that is most strongly associated with MS. Network science approaches have been effectively used to examine network structure as it relates to clinical conditions, aging, and language. The present study utilizes a network science approach to investigate whether individuals with MS exhibit less interconnected and resilient semantic networks compared to age-matched neurotypical peers. METHOD: We used semantic fluency data from 89 participants with MS and 88 neurotypical participants to estimate and analyze the semantic network structure for each participant group. Additionally, we conducted a percolation analysis to examine the resilience of each network. RESULTS: Network measures showed that individuals with MS had lower local and global clustering coefficients, longer average shortest path lengths, and higher modularity values compared to neurotypical peers. Small-worldness, network portrait divergence measures, and community detection analyses were consistent with these results and indicated that macroscopic properties of the two networks differed and that the semantic network for individuals with MS was more fractured than the neurotypical peer network. Moreover, a spreading activation simulation and percolation analysis suggested that the semantic networks of individuals with MS are less flexible and activation degrades faster than those of age-matched neurotypical participants. CONCLUSIONS: These differing semantic network structures suggest that language retrieval difficulties in MS partially result from decline in language-specific factors.

RESUMO

PURPOSE: Article-noun disagreement in spoken language is a marker of children with developmental language disorder (DLD). However, the evidence is less clear regarding article comprehension. This study investigates article comprehension in monolingual Spanish-speaking children with and without DLD. METHOD: Eye tracking methodology used in a longitudinal experimental design enabled the examination of real time article comprehension. The children at the time 1 were 40 monolingual Spanish-speaking preschoolers (20 with DLD and 20 with typical language development [TLD]). A year later (time 2), 27 of these children (15 with DLD and 12 with TLD) were evaluated. Children listened to simple phrases while inspecting a four object visual context. The article in the phrase agreed in number and gender with only one of the objects. RESULT: At the time 1, children with DLD did not use articles to identify the correct image, while children with TLD anticipated the correct picture. At the time 2, both groups used the articles' morphological markers, but children with DLD showed a slower and weaker preference for the correct referent compared to their age-matched peers. CONCLUSION: These findings suggest a later emergence, but a similar developmental trajectory, of article comprehension in children with DLD compared to their peers with TLD.

RESUMO

This study investigated the use of referring expressions in Mandarin-speaking children with and without developmental language disorder (DLD). The data consist of narratives elicited from 18 children with DLD and 18 typically-developing (TD) children matched on chronological age. Participants' referring expressions were analysed in terms of referential form, function, and adequacy. The overall results of form - function mappings showed that the two groups of children were quite similar in their referential choices, indicating that both groups were sensitive to function constraints and listener needs. On the other hand, children with DLD were less successful than TD children in producing adequate subsequent mentions, suggesting that referential adequacy would be useful for identifying areas of difficulty children with DLD would have in referencing.

RESUMO

PURPOSE: 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. METHOD: 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. RESULTS: 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. CONCLUSIONS: 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.

PURPOSE: This study reports on a program to train student clinicians to provide recast therapy on complement clauses to children with developmental language disorder (DLD). To determine the efficacy of the program, we conducted secondary data analysis based on Owen Van Horne et al. (2023) and examined student clinicians' recasts after training and children's progress after treatment. METHOD: Three student clinicians received a two-stage training, followed by a real intervention program targeting complement clauses in six children with DLD. A third of the intervention sessions were coded for the total number and number of unique verbs in complement clauses provided by the student clinicians. An elicited production task was completed to test children's knowledge of the target structure. RESULTS: On average, student clinicians provided 30 targeted recasts to each child during each intervention session. They provided a greater number of and more variable input for that compared to WH complements. Children demonstrated significant improvement only in WH, but not in that, complements. CONCLUSIONS: A targeted training program could strengthen clinicians' ability to provide recast therapy on complex syntax; however, future refinements should shorten and broaden training to include more targets. A mismatch between input patterns and learning patterns was observed. WH complement input is more stable than that input, given the less variable complement-taking verbs provided by the student clinicians and the overtness of the WH word as a stable complementizer, which may have facilitated the identification and extraction of the target syntactic structure.

RESUMO

PURPOSE: Frustration is an emotion often clinically reported by persons who stutter. So far, mainly questionnaire-based studies have reported findings related to increased frustration or decreased frustration tolerance. The aim of this preliminary study was to determine possible group differences between children who stutter (CWS) and children who do not stutter (CWNS) using a behavioral experimental task, as well as to evaluate possible associations with the frequency, duration, and physical concomitants of stuttering disfluencies. METHOD: Participants were 13 CWS (mean age = 6;05 years) and 13 CWNS (mean age = 6;06 years), matched on age (±4 months) and gender. Frustration tolerance was assessed by the Delay Frustration task. This task includes normal delay, short delay, and long delay trials. Responses during long delay trials provide an indication of frustration tolerance and were recorded across time intervals during the response window. RESULTS: CWS, compared to CWNS, responded more frequently during the long delay trials, which is indicative of higher delay frustration. The variation in responding across time within intervals was similar for both groups. Decreased frustration tolerance was associated with increased duration of stuttered disfluencies and of physical concomitants. CONCLUSIONS: In general, the current findings seem to provide support for earlier theoretical conceptualizations about the role of emotional reactivity in the development of stuttering.

RESUMO

The ability to associate different types of number representations referring to the same quantity (symbolic Arabic numerals, signed/spoken number words, and nonsymbolic quantities), is an important predictor of overall mathematical success. This foundational skill-mapping-has not been examined in deaf and hard-of-hearing (DHH) children. To address this gap, we studied 188 4 1/2 to 9-year-old DHH and hearing children and systematically examined the relationship between their language experiences and mapping skills. We asked whether the timing of children's language exposure (early vs. later), the modality of their language (signed vs. spoken), and their rote counting abilities related to mapping performance. We found that language modality did not significantly relate to mapping performance, but timing of language exposure and counting skills did. These findings suggest that early access to language, whether spoken or signed, supports the development of age-typical mapping skills and that knowledge of number words is critical for this development.
