Y luego un tiburón blanco ha abrido la boca: Spanish children’s overregularization of irregular past participles

Abstract The current study investigates the influence of Age, Lexical frequency, and Language background on children’s overregularization of irregular past participles (e.g., ponido ‘put’, cf. puesto). A total of 536 past participles used in compound tenses (e.g., he escrito ‘I have written’) were extracted from child speech in online corpora from both monolingual Spanish (N = 45) and Spanish-English bilingual children (N = 2) between the ages of 3;0 and 6;11. The children overregularized 7 % of their past participles and did so more often with low-frequency participles like escrito ‘written’ than with high-frequency ones like hecho ‘done/made’. Additionally, Spanish-English bilinguals overregularized more than the monolinguals, and the bilinguals’ overregularizations persisted with age while the monolingual children’s rates decreased with age. These results demonstrate that both monolingual and bilingual children overregularize irregular past participles in the structures of interest and that their overregularizations are mediated by lexical frequency. Further, these results suggest that children must be exposed to enough examples of irregular forms before they stop applying the regular pattern. While the monolingual children who were exposed to extended amounts of Spanish retreated from participle overregularization with age, bilinguals’ rates of overregularization persisted through the ages studied. These findings indicate that children from both speaker groups follow a similar acquisitional path of irregular past participles; however, language experience predicts their rates of overregularization, and the timespan required to master the irregulars.

Where to start: Use of the bilingual multidimensional ability scale (B-MAS) to identify developmental language disorder (DLD) in bilingual children

Purpose The identification of developmental language disorder (DLD) is challenging for clinicians who assess bilinguals. This paper introduces a protocol-based approach, the Bilingual Multidimensional Ability Scale (B-MAS), for expert raters to identify DLD in bilinguals. Method Three bilingual speech-language pathologists (SLPs) reviewed 166 Spanish-English bilingual children’s profiles, which included performance on direct (morphosyntax, semantics, and narrative tasks) and indirect (parent/teacher survey) measures in both languages. A multidimensional scale (0–5) was adopted to rate children’s performance. A diagnosis of DLD was made if at least two raters assigned a summary rating of ≤2. Result Analysis of the scores on the B-MAS resulted in the identification of 21 children as having DLD. Though different strategies were employed to make decisions, the three SLPs demonstrated high inter-rater agreement across different ratings (intraclass correlation coefficient values ranged from .83 to .90). Conclusion For bilingual populations that are understudied and for which gold standards of assessment are not available, the B-MAS can be adopted as a starting point to study DLD or as a reference standard to develop new assessment tools in that population. Clinically, this protocol could be tailored and evaluated by a group of SLPs serving a large population of a particular bilingual group for diagnostic purposes.

Diagnostic Accuracy of Grammaticality and Utterance Length in Bilingual Children.

The purpose of this study was to investigate the diagnostic accuracy of two measures derived from spontaneous language samples, mean length of utterance in words (MLUw) and percentage of grammatical utterances (PGU), in identifying developmental language disorder (DLD) in Spanish-English bilingual children. We examined two approaches: best language and total language. The participants in this study included 74 Spanish-English bilingual children with (n = 36) and without (n = 38) DLD. Language samples were elicited through a story retell and story generation task using Frog wordless picture books in English and Spanish. Stories were transcribed and coded using the Systematic Analysis of Language Samples (Miller & Iglesias, 2020) to extract MLUw and PGU in both languages. Logistic regression analyses suggested that a model that included PGU, MLUw, and age achieved the best diagnostic accuracy in predicting group membership. Both approaches, best language and total language, had fair diagnostic accuracy. In combination, PGU and MLUw seem to be useful diagnostic tools to differentiate bilingual children with and without DLD. Clinical implications and usability are discussed.

On the Acquisition of Differential Object Marking in Child Heritage Spanish: Bilingual Education, Exposure, and Age Effects (In Memory of Phoebe Search)

Studies on school-aged children have been infrequent in research on Spanish as a heritage language. The present study explored how dual-language immersion education, patterns of heritage language use, proficiency, and age shape child Spanish heritage speakers’ production and selection of differential object marking (DOM). A total of 57 English–Spanish bilingual children and 18 Spanish-dominant adults completed sentence completion and morphology selection tasks. Results revealed that the group of heritage speaker children that produced and selected the differential object marker most frequently was the seventh and eighth grade children (ages 12–14, the oldest in the study) who had completed a dual-language immersion program. Different factors accounted for variability in each task: bilingual education and proficiency affected the production of DOM, while age affected selection. Heritage speakers selected DOM more frequently than they produced this structure. These findings have implications for theories of heritage language acquisition that emphasizes that language experience and exposure account for differences between heritage speakers and argue for the dissociation of production from underlying syntactic knowledge. The data also argue that heritage speakers may possess a bilingual alignment for DOM, whereby underlying receptive knowledge is modulated by cumulative exposure, while production depends more on bilingual education and proficiency in Spanish.

Early bilingualism enhances theory of mind in children from low-income households via executive function skills

The study focuses on children in poverty and investigates whether early bilingualism enhances economically disadvantaged children’s Theory of Mind (ToM), and what role Executive Function plays in the relation between bilingualism and ToM. Sixty-eight preschool-aged children (35 English monolinguals, 51.4% boys, and 33 English-Spanish bilingual children, 57.5% boys) from low-income backgrounds completed standardized language assessments, three executive function tasks, and a five-task ToM battery. Results showed that after controlling for children’s age, income-to-needs ratio, and English proficiency, bilingual children demonstrated greater ToM competence compared to monolingual children. A higher degree of bilingualism was associated with better ToM performance in bilingual children. Mediation analyses showed that children’s working memory and attention shifting accounted for the links between bilingualism and ToM. The findings suggest that an early bilingual learning experience may facilitate preschool children’s ToM development in economically disadvantaged environments, and this relation was differentially impacted by executive function components.

Neural Correlates of Morphosyntactic Processing in Spanish-English Bilingual Children: A Functional Near-Infrared Spectroscopy Study.

The aim of this study was to examine the effects of early bilingual exposure on Spanish-English bilingual children's neural organization of English morphosyntactic structures. This study examines how children's age and language experiences are related to morphosyntactic processing at the neural level. Eighty-one children (ages 6-11 years) completed an auditory sentence judgment task during functional near-infrared spectroscopy neuroimaging. The measure tapped into children's processing of early-acquired (present progressive -ing) and later-acquired (past tense -ed and third-person singular -s) English morphosyntactic structures, the primary language of academic instruction. We observed effects of syntactic structure and age. Early-acquired morphemic structures elicited activation in the left inferior frontal gyrus, while the later-acquired structures elicited additional activations in the left middle temporal gyrus and superior temporal gyrus (STG). Younger children had a more distributed neural response, whereas older children had a more focal neural response. Finally, there was a trending association between children's English language use and left STG activation for later-acquired structures. The findings inform theories of language and brain development by highlighting the mechanisms by which age and language experiences influence bilingual children's neural architecture for morphosyntactic processing.

Relationships Among Motor, First, and Second Language Skills Among Bilingual Children With Language Disorders.

The purpose of this study was to determine the significance and directions of the relationships among oral and manual fine motor skills and language abilities among Spanish-English bilingual children. If such relationships exist, this would support a shared biological influence on motor and language development. Participants included 56 bilingual children, 24 of whom met criteria for developmental language disorder (DLD), recruited based on teacher concern for language and/or reading comprehension abilities. Students participated in a battery of baseline tests to determine motor, language, and cognitive abilities. Correlations among all variables were examined for direction of relationships. Regression models explored the predictive power of motor skills with Spanish and English language ability as the outcome measure. Oral fine motor abilities (diadochokinetic rate productions of /pa/ and /pata/) predicted Spanish (but not English) oral language abilities in the expected direction (i.e., faster rates were associated with better language). Manual fine motor performance on computer tapping tasks was not related to performance in either language. Oral fine motor abilities are related to language abilities in bilingual children, but only for the native language. We did not find reliable differences in oral and manual fine motor skills between groups of bilingual children with and without DLD. These findings support a limited role of shared biological influences on motor and language development.

Code-Switching During Narratives by Bilingual Children With and Without Developmental Language Disorder.

This study examined the frequency, direction, and structural characteristics of code-switching (CS) during narratives by Spanish-English bilingual children with and without developmental language disorder (DLD) to determine whether children with DLD exhibit unique features in their CS that may inform clinical decision-making. Spanish-English bilingual children, aged 4;0-6;11 (years;months), with DLD (n = 33) and with typical language development (TLD; n = 33) participated in narrative retell and story generation tasks in Spanish and English. Instances of CS were classified as between utterance or within utterance; within-utterance CS was coded for type of grammatical structure. Children completed the morphosyntax subtests of the Bilingual English-Spanish Assessment to assist in identifying DLD and to index Spanish and English morphosyntactic proficiency. In analyses examining the contributions of both DLD status and Spanish and English proficiency, the only significant effect of DLD was on the tendency to engage in between-utterance CS; children with DLD were more likely than TLD peers to produce whole utterances in English during the Spanish narrative task. Within-utterance CS was related to lower morphosyntax scores in the target language, but there was no effect of DLD. Both groups exhibited noun insertions as the most frequent type of within-utterance CS. However, children with DLD tended to exhibit more determiner and verb insertions than TLD peers and increased use of "congruent lexicalization," that is, CS utterances that integrate content and function words from both languages. These findings reinforce that use of CS, particularly within-utterance CS, is a typical bilingual behavior even during narrative samples collected in a single-language context. However, language difficulties associated with DLD may emerge in how children code-switch, including use of between-utterance CS and unique patterns during within-utterance CS. Therefore, analyzing CS patterns may contribute to a more complete profile of children's dual-language skills during assessment. https://doi.org/10.23641/asha.23479574.

A cross-sectional investigation of disfluencies in typically developing Spanish-English bilingual children

PurposeThis study examined the language skills and the type and frequency of disfluencies in the spoken narrative production of typically developing Spanish-English bilingual children. MethodA cross-sectional sample of 106 bilingual children (50 boys; 56 girls) enrolled in kindergarten through Grade 4, produced a total of 212 narrative retell language samples in English and Spanish. A specialized fluency coding system was implemented to index the percentage of total (%TD) and stuttering-like disfluencies (%SLD) in each language. Large-scale reference databases were used to classify children’s dual language proficiency profiles (balanced, English dominant, Spanish dominant) based on language sample analysis measures of morphosyntax and lexical diversity. ResultsThe bilingual Spanish-English children in this study did not demonstrate significant cross-linguistic differences for mean %TD or %SLD. However, the mean %TD and %SLD in both languages exceeded the risk threshold based on monolingual English-speaking norms. English dominant bilingual children demonstrated significantly lower %TD in English than Spanish. Spanish dominant children demonstrated significantly lower %SLD in Spanish than English. ConclusionsThis study included the largest sample size of bilingual Spanish-English children investigated to date from a fluency perspective. The frequency of disfluencies was found to be variable across participants and change dynamically as a function of grade and dual language proficiency profiles, indicating the need for studies that employ larger sample sizes and longitudinal designs.

A cross-linguistic approach to treating speech sound disorders in bilingual children

ABSTRACT The present study explores generalisation of production skills across languages when treating speech sound disorders in bilingual children. Early work suggests that treating shared sounds across languages may facilitate cross-linguistic generalisation. Thus, selecting shared sounds across languages as targets may have clinical advantages. In this study, we asked if cross-linguistic generalisation can be facilitated for targets using shared sounds in bilingual children with phonological delays from Spanish (L1) into English (L2) when treating only the L1. Two Spanish-English bilingual children between the ages of 5;0–5;3 with speech sound disorders participated in an intervention with shared sounds as targets. Each child received two sessions per week of therapy that included both linguistically-based and motor-based approaches. Accuracy of targets was assessed within and across languages using a single-subject case design. Results show increased accuracy of targets and generalisation of sounds across languages when treatment was administered only in the L1. Specific growth varied per target and child. The implications affect how we select treatment targets in bilingual children. Future studies should explore additional ways to select targets to increase generalisation of skills and replicate with additional participants.

A Complexity Approach to Promoting Within- and Cross-Language Generalization in Bilingual Children With Phonological Delays.

The purpose of this study was to explore the effects of generalization when treating complex targets with shared sounds in Spanish for a 5-year-old Spanish-English bilingual child with a phonological delay. Two complex clusters (/fl/ and /fɾ/) and one additional target (/l/) were chosen for treatment. Intervention sessions were held in Spanish over the course of 1 year on a weekly basis. The accuracy of the treated and untreated targets was monitored using a single-subject case design and was assessed using visual analysis. The accuracy of the production of treated targets increased upon administering the intervention. Accuracy also increased for untreated /fl/ targets in Spanish and English, /l/ in English, and untreated /fɾ/ clusters in Spanish. The results suggest that choosing complex targets consisting of shared sounds helps promote the generalization of skills within and across languages. Future studies should examine the outcomes of selecting additional forms of complex targets for bilingual children.

L2 vocabulary learning in a mixed-proficiency community-engaged program: Designing vocabulary instruction for college students

Although extensive research exists on the personal, social, and academic outcomes of community-engaged programs (CEPs), limited research exists on vocabulary learning and students’ perceptions of their own vocabulary learning through participation in a CEP. Likewise, limited research exists on vocabulary learning in mixed-proficiency groups of Spanish second language (L2) learners. This study contributes to the current literature by exploring the vocabulary learning of 57 mixed-proficiency L2-Spanish college students who participated in a health-focused after-school program with Spanish–English bilingual children in a Midwestern city in the US. The higher proficiency students were enrolled in a language-focused class, whereas the lower-level students were enrolled in a Spanish for health professional’s class. Student reflective narratives revealed positive perceptions of vocabulary learning during the CEP, as vocabulary learning was seen to be fundamental to connecting with children in the Latino community. Productive vocabulary tests revealed significantly higher gains on vocabulary items that had been explicitly taught in class, but gains varied according to learners’ proficiency levels. Lower-level students showed both higher gains and a higher perception of vocabulary gains than more advanced students. Students’ reflective narratives suggest that the focus on health content in the lower-level class may have contributed both to vocabulary gains and to students’ awareness of learning. Recommendations for effective vocabulary instruction for mixed-proficiency students in a CEP are presented.

Semantic Difficulty for Bilingual Children: Effects of Age, Language Exposure, and Language Ability.

Semantic tasks evaluate dimensions of children's lexical-semantic knowledge. However, the relative ease of semantic task completion depends on individual differences in developmental and language experience factors. The purpose of this study was to evaluate how language experience and language ability impact semantic task difficulty in English for school-age Spanish-English bilingual children with and without developmental language disorder (DLD). Participants included 232 Spanish-English bilingual children in second through fifth grade with (n = 35) and without (n = 197) DLD. Data included children's performance on the English Semantics subtest of the Bilingual English-Spanish Assessment-Middle Extension Field Test Version (BESA-ME), age of English acquisition, and percent English language exposure. Task difficulty, a measurement of the relative ease of task completion, was calculated for six semantic task types included on the BESA-ME. Multilevel regression modeling was conducted to estimate longitudinal growth trajectories for each semantic task type. Results showed that language ability and grade level drive semantic task difficulty for all task types, and children with DLD experienced greater difficulty on all task types compared to their typically developing peers. Longitudinally, semantic task difficulty decreased for all children, regardless of language ability, indicating that semantic task types became easier over time. While children made gains on all semantic tasks, the growth rate of task difficulty was not equal across task types, where some task types showed slower growth compared with others. English language exposure emerged as a significant predictor of semantic task difficulty while age of acquisition was not a significant factor. This study clarifies developmental profiles of lexical-semantic performance in bilingual children with and without DLD and supports clinical decision-making regarding children's English language learning.

Complexity and cross-linguistic transfer in intervention for Spanish-English bilingual children with speech sound disorder.

With bilingual children, intervention for speech sound disorders must consider both of the child's phonological systems, which are known to interact with each other in development. Further, cross-linguistic generalization following intervention for bilingual children with speech sound disorders (i.e., the impact of treatment in one language on the other) has been documented to varying degrees in some prior studies. However, none to date have documented the cross-linguistic impact of treatment with complex targets (e.g., consonant clusters) for bilingual children. Because complex phonological targets have been shown to induce system-wide generalization within a single language, the potential for bilingual children to generalize learning across languages could impact the efficiency of intervention in this population. This pilot intervention study examines the system-wide, cross-linguistic effects of treatment targeting consonant clusters in Spanish for two Spanish-English bilingual children with phonological disorder. Treatment was provided with 45-minute sessions in Spanish via teletherapy, three times per week for six weeks. Comprehensive phonological probes were administered in English and Spanish prior to intervention and across multiple baselines. Pre-intervention data were compared to data from probes administered during and after intervention to generate qualitative and quantitative measures of treatment outcomes and cross-linguistic generalization. Results indicate a medium effect size for system-wide generalization in Spanish (the language of treatment) and English (not targeted in treatment), for both participants (mean effect size in Spanish: 3.6; English 4.3). These findings have implications for across-language transfer and system-wide generalization in treatment for bilingual children.

What predicts individual response to language treatment in bilingual children with developmental language disorder?

For bilingual children with developmental language disorder (DLD), language treatment response is the degree to which an individual child progresses in both of their languages. Understanding what predicts language treatment response for an individual child can help clinicians plan treatment more effectively. This study is a retrospective analysis of data from Ebert et al. (2014). Participants included 32 school-age Spanish-English bilingual children with DLD who completed an intensive language treatment program. Gains in Spanish and English were measured using raw test scores in each language. Predictors of language gains include language, cognitive, and demographic variables. To examine which predictors were significant, we calculated partial correlations between the potential predictors and the posttreatment language test scores, controlling for the effects of pretreatment test scores. In Spanish, several predictors correlated with the outcome measures. After controlling for pretreatment scores, English grammaticality, female sex, processing speed, age, and fluid reasoning were related to Spanish posttreatment scores. In English, correlations with individual predictors were minimal. After controlling for pretreatment scores, only one variable was associated with one English posttreatment score: English grammaticality. The original study reported limited gains in Spanish compared to robust gains in English (Ebert et al., 2014). Treatment response in Spanish is more variable given the lack of environmental support for Spanish in the US. As a result, individual factors (including nonverbal cognition, pretreatment language levels, and demographic variables) influence treatment gains in Spanish. In contrast, strong environmental support for English supports a more consistent treatment response, with a smaller role for individual factors.

Bilingual children’s vocabulary skills at 5 years predict reading comprehension development within, not across, languages

ABSTRACT Extensive evidence indicates that early vocabulary skills predict later reading development among monolingually developing children. Some evidence suggests that a relationship between vocabulary and later reading also holds across languages among children whose home language differs from the school language. However, these findings have been mixed and it remains unclear if, and under what circumstances, vocabulary in one language supports reading comprehension development in another. The present study followed 84 Spanish-English bilingual children, assessing their vocabulary skills at 5 years and their reading comprehension at 6, 7, 8, and 9 years. Longitudinal multilevel models revealed significant within-language relations between early vocabulary knowledge and subsequent reading comprehension in both English and Spanish and no across-language relations. There were significant concurrent across-language relations between English and Spanish reading comprehension skills. These findings suggest that the contribution of vocabulary knowledge to reading comprehension is language specific but that there are also language general components to reading comprehension, which result in significant concurrent relations between reading comprehension skill across languages.

Interaction in bilingual early speech acquisition: Acceleration in the bilingual acquisition of English liquids for English-Spanish bilinguals

This study contributes to the understanding of bilingual speech sound acquisition, as it explores substitution patterns by preschoolers undergoing a language shift. Specifically, it investigates the distribution of glides [j w] as substituted sounds for rhotics and laterals sounds in English and Spanish. Spanish glides [j] and [w] share acoustic and phonological features with the high vowels [i] and [u], whereas English includes both glides in the consonant inventory. In English, the substitution pattern of gliding ([w]abbit) is frequently found in preschoolers, but it does not occur in monolingual Spanish-speaking children. Gliding was studied in Spanish-English bilingual and monolingual English-speaking children born and raised in a southwest border region of the U.S. Single word outputs of 61 typically-developing children were analyzed. Twenty-two (36%) exhibited gliding (11 bilingual children and 11 monolingual children). Through quantitative and qualitative analysis, this study shows evidence of distributed phonological systems and between-language interactions (Paradis, 2001). Gliding was found to occur significantly more often in English monolingual than Spanish-English bilingual children. Additionally, cross-linguistic effects were found in the Spanish data. These results indicate that maintenance of the minority language at home bootstraps the acquisition of English rhotics for these bilingual Spanish-English preschoolers in the borderlands.

Understanding (un)grammaticality in context: Evidence from young Spanish-English bilinguals over time

PurposePercent grammatical utterances (PGU) provides clinicians and researchers with meaningful information on young children's grammatical abilities (Eisenberg & Guo, 2016). However, work is still needed to place PGU within the context of conventional language sample measures and understand how PGU reflects grammatical development in bilingual populations. The current study focuses on Spanish-English bilingual preschoolers to examine: 1) change in Spanish and English PGU over one year of preschool English instruction, 2) associations between PGU and other language sample measures within each language and across time, and 3) the types and frequency of error patterns in each language. MethodPlay-based language samples were elicited in English and Spanish from bilingual children (n = 19) at the beginning and end of an instructional preschool year in English. PGU was derived from each sample along with other language sample measures (e.g., mean length of utterance). We examined change in PGU from Time 1 to Time 2, and correlations between Time 1 PGU and Time 2 PGU for each language. Specific grammatical errors were described in terms of their frequency in each language and stability across time. ResultsAverage English PGU increased from Time 1 to Time 2, and correlated with other language sample measures. Conversely, average Spanish PGU did not increase from Time 1 to Time 2, nor did PGU correlate with any other Spanish measure. Error patterns in each language reflected grammatical differences across English and Spanish. ConclusionsOur results revealed distinct developmental patterns in bilingual children's first and second languages. Associations between time points and measures in English contrasted with disassociations in Spanish. Error patterns revealed more detailed information as to how bilingual children begin to acquire grammatical structures in each of their languages. We provide a case example to illustrate how grammaticality and error patterns can be used to characterize children's language abilities. We conclude with clinical implications of grammaticality in Spanish-English bilingual children.

Evaluating how language and masked-speech recognition change over time for bilingual children in the Midwest

Spanish-English bilingual children living in the US often become more proficient in English compared to Spanish over time, in part due to education models. For example, most bilingual children in the Midwest receive educational instruction in English or rapidly transition to English-only instruction. If a bilingual child’s relative proficiency shifts, how does that shift affect their speech recognition? To address this question, we invited participants from the Children’s English and Spanish Speech Recognition Test (ChEgSS) normative study back three years later to retest their speech recognition. The initial study evaluated word recognition in 83 Spanish-English bilingual children with normal hearing. Children completed Spanish and English word recognition tests in speech-shaped noise and two-talker speech using a 4AFC procedure. Language proficiency and language use were assessed using standardized tests and a questionnaire. Results indicated that age and receptive vocabulary influenced word recognition performance. In this study we retested a subgroup of children who were between the ages of 4-8 years in the initial study using the same procedures. Results will advance our understanding of the association between language proficiency and word recognition in this demographic of bilingual children.

The effect of speaker reliability on word learning in monolingual and bilingual children

The present study examined the effect of speaker reliability on novel word learning in 4- and 5-year-old English-speaking monolingual (N = 25) and Spanish-English bilingual (N = 25) children, using an eye-tracking paradigm. Results revealed that children retained novel labels taught by both the reliable and the unreliable speaker. Yet, time-course analyses revealed that children showed faster word recognition in the reliable condition but demonstrated more persistent looks to target in the unreliable condition. This suggests that speaker reliability impacts the time-course of retrieval, but not the ultimate retention of novel words. No group differences were observed in children’s overall accuracy of novel word learning, although monolingual and bilingual children did demonstrate subtle differences in the time-course of novel word recognition. Together, the findings suggest that while speaker cues shape the process by which children recognize newly-learned words, language experience has minimal influence on this process.
