Language Production In Children Research Articles

Struktur Produksi Bunyi Bahasa Anak Usia 2 Tahun (Studi Kasus Ilyas)

The production structure of sound in language by 2-year-old children is an interesting issue in the realm of language research. It lies in the imperfect yet meaningful language production of children. In their language production, some sound omissions and changes occur. This research aims to describe the structure of sound production in 2-year-old children. It is a field research conducted using a qualitative descriptive method. The research findings indicate that the structure of sound production involves sound omissions and changes. Sound omissions occur in consonant sounds such as [r], [m], [n], [ŋ], [t], [k], and [l]. Sound changes occur in sounds such as [t→c], [s→c], [au→o], and [ai→e]. These omissions and changes consistently occur

Morphological and phonological errors in the written language production of children with DLD

ABSTRACT The present study aims to investigate the written language production in Greek of Developmental Language Disorder (DLD) children and compare it to that of typically developing (TD) children matched for gender and chronological age. The participants of the study were 31 children with DLD (7.6 years old) and 31 TD children (7.7 years old). All the participants were asked to write a text on a specific prompt they were given by the researchers. Both groups were assessed for the total number of words produced in text, the proportion of incorrectly spelt words in text, the total number of morphological errors and the total number of phonological errors produced. In addition, the specific type of morphological and phonological errors students produced in their written texts of the DLD group were also taken into consideration. The findings of the study showed that the DLD group performed worse in almost all measurements as compared to their TD peers and that their errors concerned mainly replacement, omission or addition of graphemes or syllables. Further research is needed on the written production of individuals with DLD in order to replicate those findings and contribute to the almost non-existing knowledge concerning written production in Greek.

Spatial Language and Cognition in Autistic Preschoolers.

ASD is associated with relative strengths in the visuospatial domain but varying abilities in the linguistic domain. Previous studies suggest parallels between spatial language and spatial cognition in older autistic individuals, but no research to date has examined this relationship in young autistic children. Therefore, the purpose of the present study was to investigate the connection between children's spatial language production and nonverbal spatial cognition over time. We also examined two potential predictors of spatial language observed in previous literature, ASD symptom severity and parent spatial language input. In past work investigating spatial language in NT children of the same age, parent-child interactions have been a primary context for study. Therefore, in the present study, we analyzed transcripts of dyadic naturalistic play interactions between autistic children and their parents over three visits from age 30 to 66 months and administered standardized cognitive and ASD diagnostic assessments at each visit. Spatial language production was related to nonverbal spatial cognition even when accounting for overall language production, though the strength of that relationship decreased over time. Parent spatial input (but not ASD severity) significantly predicted children's spatial language production over and above the effect of overall language production. Spatial language is associated with spatial cognition in young autistic children and appears to reflect the interaction of overall linguistic skills and nonverbal spatial cognitive ability regardless of autism severity. Parent-mediated interventions may be a promising context for increasing spatial language in autistic preschoolers.

The Pausing Strategies in Chinese Preschool Children's Narratives.

Language production, a dynamic process involving real-time language processing, is crucial for children's language and communication development. To explore the early development of children's real-time language production, this study investigated Chinese preschool children's pausing strategies in narratives and their associations with verbal working memory and vocabulary abilities. A picture-elicited narrative task was employed. Sixty Mandarin-speaking children aged 4-5 years were asked to tell a story according to the book Frog, Where Are You? The pausing types and positions in narratives were coded and analyzed. Additionally, children's verbal working memory and vocabulary were measured. The results showed that 4- to 5-year-old children prefer to use silent pauses and tend to produce pauses within clauses. The total frequency of pausing decreases with age and shows a significant gender difference. Girls prefer to use within-clause pauses, whereas boys prefer to use between-clause pauses. More importantly, children's pausing frequency is closely associated with their verbal working memory and vocabulary, in which working memory plays a more important role. This study is a first-step exploration of pausing strategies in 4- to 5-year-old Chinese children's narratives. The developmental characteristics of pausing strategies shown in typically developing children serve as a crucial reference for interventions for children with language deficits.

Usvajanje jezika kod djece uzrasta dvije i tri godine / Language Acquisition in Children Aged Two and Three

This paper discusses language acquisition in children aged two and three. The analysis was carried out on a corpus of child language compiled during research conducted at a kindergarten in Sarajevo among children aged two and three who acquire their native language in the area of Sarajevo, Bosnia and Herzegovina. Qualitative and quantitative methods were applied in the corpus analysis. The development of child language production was measured by the Mean Length of Utterance, based on the number of words per utterance (MLUw). The distribution of parts of speech was established for both age groups. A special emphasis was placed on the ratio between the number of nouns and the number of verbs. The results have confirmed the nativist natural partitions hypothesis, according to which nouns are predominant in children’s early speech over verbs and other parts of speech. MacArthur Communicative Development Inventory (MCDI) was applied in the semantic analysis of nouns. The analysis confirmed the hypothesis that nouns denoting animate beings have a higher prevalence over nouns denoting inanimate objects at the early stages of language acquisition. In addition, the presence of complex and abstract concepts was detected, which supports the theory of the existence of an innate language acquisition device in humans. The creative aspect of child language was also analysed, along with differences between the language of children and the language of adult speakers.

Reverse Engineering Language Acquisition with Child-Centered Long-Form Recordings

Language use in everyday life can be studied using lightweight, wearable recorders that collect long-form recordings—that is, audio (including speech) over whole days. The hardware and software underlying this technique are increasingly accessible and inexpensive, and these data are revolutionizing the language acquisition field. We first place this technique into the broader context of the current ways of studying both the input being received by children and children's own language production, laying out the main advantages and drawbacks of long-form recordings. We then go on to argue that a unique advantage of long-form recordings is that they can fuel realistic models of early language acquisition that use speech to represent children's input and/or to establish production benchmarks. To enable the field to make the most of this unique empirical and conceptual contribution, we outline what this reverse engineering approach from long-form recordings entails, why it is useful, and how to evaluate success.

Parenting Stress and Language Development in Children: Associations in Angelman Syndrome and Down Syndrome

One of the defining characteristics of neurogenetic syndromes such as Angelman syndrome (AS) and Down syndrome (DS) is delayed language development. Although it is commonly reported that parenting stress is associated with language development, these associations have not been widely studied in AS and DS despite other research showing elevated stress levels in the parents of these children. To fi ll this gap in research, the present study examined how parenting stress relates to language production in children with AS and DS. Daylong recordings were obtained from 72 participants using a Language Environment Analysis recording device, which was then processed through an online program to produce vocal productivity scores. Parents of these participants filled out the Parenting Stress Index, Fourth Edition Short Form to report their stress levels. Using linear regression, data was analyzed to determine if there is an association between language levels and parenting stress in a low- risk (LR) group and if the magnitude of that association was stronger in either the AS group or the DS group than in the LR group. Results suggested trends toward negative associations between parenting stress and language levels, though the association was not statistically significant. Th e magnitude of these associations did not differ significantly between groups. Th is negative association should be examined more with larger sample sizes, as it is important to the future development of early intervention techniques for children with AS and DS and their families.

African multilingualism viewed from another angle: Challenging the Casamance exception.

Aims and Objectives/Purpose/Research Questions:The former region of southern Senegal, the Casamance, has been portrayed throughout the literature on African multilingualism in a singular light, for example, as an area where monolingualism does not exist. The purpose of this article is to stress the previously unacknowledged importance of monolingual settings and practices by discussing data that have yet to be presented in the literature.Design/Methodology/Approach:We investigate rural multilingualism and monolingualism across the Casamance by carrying out the following four studies: (a) we conduct a survey of 62 villages with a questionnaire and our newly created ‘blindfold test’, classifying them into two main types; (b) with 34 women we study the role of exogamy in multilingual language acquisition in one of the villages; (c) we analyse child language production data and child directed speech to examine the existence of monolingual language acquisition; (d) we examine the sociolinguistic profiles of 101 speakers of one language community to investigate intergenerational multilingualism.Data and Analysis:Data were analysed using descriptive statistics in the form of frequency counts. Additionally, we couch our results on multilingualism in the theory of canonical typology.Findings/Conclusions:We propose a distinction between multilingual settings, e.g. communities where speakers are most likely to accommodate, and who live among villages largely located on national roads and around cities, and monolingual settings, which constitute most of the villages of the Casamance and where language acquisition is monolingual and where migration, rather than exogamy, accounts for the development of individual multilingualism.Originality:This article contributes unprecedented research methodology for the study of complex multilingual situations such as those found in African multilingual contexts.Significance/Implications:Our study adds to the growing understanding of small-scale multilingualism and the emergence of multilingualism in monolingual contexts.

An infant-led approach to complementary feeding is positively associated with language development.

The timing and strategy with which parents first introduce their infants to solid foods may be an important predictor of subsequent developmental outcomes. Recent years have seen a decline in the prevalence of traditional parent‐led feeding of soft, puréed food and a rise in the prevalence of infant‐led complementary feeding. Although there has been some research espousing the benefits of infant‐led complementary feeding for improving food fussiness and self‐regulation, there has been little exploration of this approach that may impact on other developmental outcomes in children. The current study explores whether aspects of the infant‐led approach, specifically the child eating unaided and consuming finger foods and eating with the family, are related to child language outcomes. One hundred thirty one parents of children aged 8–24 months completed questionnaires about their approach to complementary feeding, their current feeding practices, their child's experiences with family foods and child language comprehension/production. The findings suggest that an approach to complementary feeding which promotes infant autonomy in feeding (i.e., eating finger foods rather than puréed foods) and consuming more family foods is related to more advanced child language production and comprehension. Specifically, the prevalence of eating family foods mediated the relationship between eating unaided at the onset of the complementary feeding period and later language outcomes. This study is the first to find a significant relationship between different approaches to introducing solid foods and child language outcomes and these findings highlight the potential for different complementary feeding approaches to influence behaviour beyond mealtimes.

Speaking of State of Mind: Maternal Mental Health Predicts Children's Home Language Environment and Expressive Language.

Maternal depression and anxiety are potential risk factors to children's language environments and development. Though existing work has examined relations between these constructs, further work is needed accounting for both depression and anxiety and using more direct measures of the home language environment and children's language development. We examined 265 mother-infant dyads (49.6% female, Mage = 17.03 months) from a large city in the Western United States to explore the relations between self-reports of maternal depression and anxiety and observational indices of the home language environment and expressive language as captured by Language Environment Analysis (LENA) and parent-reported language comprehension and production. Results revealed maternal depressive symptoms to be negatively associated with home language environment and expressive language indices. Maternal anxiety symptoms were found to be negatively associated with children's parent-reported language production. These findings provide further evidence that maternal mental health modulates children's home language environments and expressive language.

Language and Communication in Preschool Children with Autism and Other Developmental Disorders.

In this research, we studied the language and communication skills of preschool children with a diagnosis of autistic syndrome disorder (ASD) (n = 51) compared to children with other developmental disorders (DD) (n = 42), using direct measures and parental reports when assessing the development of language and communication. As a novelty, this research studied a sample of children with low language and communication skills. We found a high correlation between direct measures and parental reports for both populations. Therefore, we propose that combining the information supplied by direct measures together with that supplied by parental reports would be a suitable strategy for language assessment in these populations. In addition, the results show a delay in language comprehension with respect to language production in children with ASD, along with many difficulties with non-verbal communication, compared to children with other developmental disorders (DD). We also found significant differences between both groups with respect to lexical categories. The differences in language and communication profiles of children with ASD compared to children with other DD might have some implications for diagnoses and language intervention in these populations.

The quality of mother-toddler communication predicts language and early literacy in Mexican American children from low-income households

This longitudinal study documents the key role of early joint engagement in the language and early literacy development of Mexican American children from low-income households. This rapidly growing population often faces challenges as sequential Spanish-English language learners. Videos of 121 mothers and their 2.5-year-old children interacting in Spanish for 15 min were recorded in 2009–2011 in the Dallas-Fort Worth metropolitan area. Researchers reliably rated general dyadic features of joint engagement—symbol-infused joint engagement, shared routines and rituals, and fluency and connectedness—that have been found to facilitate language development in young English-speaking children. The construct respeto, a valued aspect of traditional Latino parenting, was also rated using 2 culturally specific items—the parent's calm authority and the child's affiliative obedience. In addition, 3 individual contributions—maternal sensitivity, quality of maternal language input, and quality of child language production—were assessed. General features of joint engagement at 2.5 years predicted expressive and receptive language at 3.6 years and receptive language and early literacy at 7.3 years, accounting for unique variance over and above individual contributions at 2.5 years, with some effects being stronger in girls than boys. The level of culturally specific joint engagement did not alter predictions made by general features of joint engagement. These findings highlight the importance of the quality of early communication for language and literacy success of Mexican American children from low-income households and demonstrate that culturally specific aspects of early interactions can align well with general features of joint engagement.

The Girl Was Watered by the Flower: Effects of Working Memory Loads on Syntactic Production in Young Children

ABSTRACT Working memory is necessary for a wide variety of cognitive abilities. Developmental work has shown that as working memory capacities increase, so does the ability to successfully perform other cognitive tasks, including language processing. The present work demonstrates the effects of working memory availability on children’s language production. Whereas most of the previous research linking working memory to language development has been correlational, we experimentally varied the working memory load during concurrent language production in children 4–5 years old. Participants were asked to describe simple picture scenes that had recently been described for them in the relatively unfamiliar, passive voice (e.g., the flower was watered by the girl). Children frequently produced the passive voice, a form of syntactic priming. These responses were performed while children sometimes retained a visual-spatial or auditory-verbal working memory load to be recalled after sentence production but there was no effect of the load on syntactic priming. In a second experiment, after hearing passive-voice descriptions of pictures, instead of relying on priming, the children were directly asked to describe the same pictures by speaking in the same “special way.” Surprisingly, under a load, children more often used the passive voice as they were instructed to do, but at the expense of producing additional semantic and grammatical errors (including some nonsensical renditions such as the girl was watered by the flower). We propose that working memory, when available, is used to impose a quality-control process whereby the semantic fidelity of the response to the stimulus picture is preserved, here at the expense of disregarding the experimental instruction to reproduce the passive voice.

The Home Literacy Environment as a Mediator Between Parental Attitudes Toward Shared Reading and Children's Linguistic Competencies.

The home learning environment plays an important role for children’s early competencies development. In particular, the early home literacy environment (HLE) that consists of all literacy resources and interactions in a family that support children’s linguistic and literacy learning is closely associated with children’s language comprehension and production. A key aspect of the HLE is shared reading that should start early in children’s life and should be part of a regular routine in the family. However, parental attitudes toward (shared) reading have hardly been analyzed.In this longitudinal study, we analyzed the associations between parental attitudes toward shared reading and children’s linguistic competencies and whether these associations may be mediated by the HLE. Further, we were interested in changes of parental attitudes over time and their association with child and family background characteristics. The sample consisted of N = 133 children with an average age of about 3 years at t1. Children were tested two more times with a 6-month period in-between each assessment. Parental attitudes toward shared reading, socioeconomic status (SES), and the HLE were assessed via parental survey. Children’s sentence comprehension, productive language, and grammar were measured with a standardized test battery. Children whose parents had a more positive attitude toward shared reading not only lived in a greater quality HLE but also performed better in the linguistic tests. In a structural equation model, an indirect effect was found showing that the HLE mediated the effect of parental attitudes on children’s linguistic competencies. Further, parental attitudes toward shared reading did not change significantly across t1 to t3, and a lower score in the SES scale was associated with a less positive attitude toward shared reading. Consequently, parental attitudes toward shared reading seem to be an important basis for individual differences in the quality of the HLE and also for children’s linguistic competencies. As these attitudes vary in the context of different family SES backgrounds, they may be a good target for interventions to support the quality of the HLE and young children’s linguistic learning.

Language Environments and Spoken Language Development of Children With Hearing Loss.

This study examined the relationships between adult language input and child language production in regard to the quantity and diversity of spoken language, as well as children's knowledge of basic concepts and vocabulary. The quantity and diversity of language provided by teachers and parents were related to children's language output and knowledge. Language ENvironment Analysis technology audio-recorded the language environments of 26 preschool children with hearing loss over 2 days. The language samples were analyzed for quantity (adult word count, child vocalization count, and conversational turn count) and diversity (lexical diversity, syntactical complexity, and clausal complexity) of language. Results indicated a relationship between adult language input and child language production, but only in regard to the quantity of language. Significant differences between the teachers and parents were reported in regard to the diversity of adult language input. These results suggest that the language input provided by adults across environments (school versus home) is considerably different and warrants further investigation.

The influence of sleep on language production modalities in preschool children with Down syndrome.

Evidence suggests that sleep may relate to oral language production in children with Down syndrome. However, these children are capable of using complex referential gestures as a compensation strategy for problems with oral production, and those with a greater productive oral vocabulary have less gestural vocabulary. The goal of this study was to explore whether sleep quality relates to oral and gestural production modalities in children with Down syndrome. We evaluated 36 preschool children with and without Down syndrome, paired by chronological age and gender, with similar sociodemographic backgrounds, using actigraphy to measure sleep behaviour and the Communicative Development Inventory for Down syndrome to measure vocabulary. Children with Down syndrome with better sleep efficiency showed more oral production but less gestural production. These results highlight the importance of sleep quality to language learning in children with Down syndrome.

Reading fluency and pitch discrimination abilities in children with learning disabilities.

BACKGROUND: Pitch perception and pitch matching may link to individual reading skills.OBJECTIVE: In this study, we examined pitch perception and pitch matching tasks in children with learning disabilities to determine whether there was any connection between these tests and the reading fluency in these children.METHOD: The study used different types of pitch discrimination tests and reading fluency tests to compare the two groups.RESULTS: Results indicated that the accuracy of pitch discrimination and reading fluency was significantly different in these children with learning disabilities relative to typically developing children. This study also indicated that they exhibit impaired pitch matching, which linked to their reading skills.CONCLUSION: The results indicate that processing and production of speech may be impacted by individuals’ musical pitch perception and matching ability. The results may also give us a piece of evidence that we need further research on how these deficits in musical pitch perception affect our speech and language production in children and adults.

The Effects of Frequency and Predictability on Repetition in Children With Developmental Language Disorder.

Purpose Studies have shown that children with typical development (TD) respond to frequency and predictability when repeating nonidiomatic multiword sequences (e.g., go wash your hands). We extended these findings by explicitly examining the interaction between frequency and predictability in a repetition task for children with developmental language disorder (DLD) and children with TD. Method We created 48 four-word phrases, manipulating two factors: the frequency of occurrence of the entire four-word phrase (e.g., look in the mirror vs. look in the basket) and the predictability of the fourth word in the phrase given the preceding three words (e.g., corn on the ___ vs. look in the ___). These phrases were presented in a repetition task to 17 children with DLD (M age = 58.89 months), 19 same-age children with TD (M age = 59.79 months), and 17 younger children with TD matched to the DLD group on nonword repetition and mean length of utterance (M age = 38.94 months). Children's repetitions were judged for the presence or absence of word and morphological errors. Only the first three words of the sequence were scored (e.g., look in the). Results We found a main effect of sequence frequency, with high-frequency sequences being repeated more accurately than low-frequency sequences, modulated by a significant interaction with predictability, where the effect of sequence frequency was larger for sequences with high-predictability contexts than for sequences with low-predictability contexts. We also found a significant effect of group, with children with DLD demonstrating poorer overall performance, particularly when compared to the same-age group with TD. Conclusions Frequency and predictability are strong predictors of language production in children with TD. These factors also have effects for children with DLD, raising important clinical questions about the design of facilitative contexts for the teaching of difficult linguistic forms.

Informal language stimulation rather than corrective feedback matters in Estonian children's language performance

The study examined associations between Estonian children's language performance and their mothers' self-reported language teaching practices, and factors related to the frequency of using these language teaching practices. Mothers reported their language teaching practices, child-rearing value orientation, and their children's expressive vocabulary at 36 months (N = 88; Mage = 35.85) via the ECDI-II. Language comprehension and production were directly assessed using the New Reynell Developmental Language Scales (NRDLS). Girls outperformed boys on language production. Children of mothers with university education scored higher than others on all language measures. Mothers with stronger autonomy orientation and fewer children reported more frequent use of informal language stimulation and corrective feedback. Self-reported informal language stimulation was positively related to children's expressive vocabulary and language comprehension, whereas corrective feedback was negatively linked to children's language comprehension and production. This study highlights the importance of engaging language-learning children into conversations rather than explicitly correcting their speech.

The development of possession in the L1 acquisition of Northern East Cree.

This study presents the first investigation of the development of possessive constructions in Northern East Cree, a polysynthetic language indigenous to Canada. It examines transcripts from naturalistic recording sessions involving one adult and one child, from age 2;01.12 to 3;08.24. Findings reveal that, despite the frequency of possessive inflection in child-directed speech, the child overwhelmingly produces a possessive construction that circumvents this morphology. This construction, named here the equational possessive strategy (EPS), is largely undescribed in existing literature but is the primary mechanism for the child to express possession. These findings have potential implications for the cross-linguistic acquisition of possessive morphology and the connections between child-directed speech and child language production.
