Exploring the effects of a repair strategies training program among children with auditory processing disorder: A pilot study.

OBJECTIVES: Children with hearing loss, as well as those with auditory processing disorder (APD), experience more communication difficulties than their normal-hearing peers. Receiving training on communication strategies has been shown to be beneficial for children with hearing loss, but little is known on the effect of such training on children with APD. The main purpose of this pilot study was to assess the effects of a repair strategies training program among children with APD. METHODS: Ten school-aged children with APD participated in a ten 60-min weekly repair strategies training program (experimental group) and ten did not receive any training (control group). In pre- and post-intervention, children were filmed while taking part in short scripted conversation situations in which communication breakdowns were introduced. Additionally, questionnaires on communication difficulties and repair skills, on life habits related to communication and education as well as on emotional well-being were filled by the children and their parents. RESULTS: In post-compared to in pre-intervention, children in the experimental group used significantly more of the repair strategies taught right after a communication breakdown occurred, used a greater variety of repair strategies, and overcame more communication breakdowns. The number of strategies needed to overcome a breakdown was not significantly different after the training compared to before. The level of difficulty to accomplish education-related life habits was generally lower, although not significantly, after entering the program than before. The individualized data showed that the studied training was more suited for children aged 9 years and older. The results of the children in the control group were not significantly different between the two measured times on all outcomes. CONCLUSION: Learning how to recognize and overcome communication breakdowns through a training program was beneficial for children with APD. The program enabled them to use a wider variety of repair strategies and to be more proactive in situations where communication is difficult. Studies are needed to further examine these findings in a larger sample of children with APD and in real-life settings.

The Influence of Bilingual Language Exposure on the Narrative, Social and Pragmatic Abilities of School-Aged Children on the Autism Spectrum.

We examined the narrative abilities of bilingual and monolingual children on the autism spectrum (AS), whether bilinguals presented stronger social and pragmatic language abilities compared to monolinguals, and the link between narrative, social, and pragmatic language abilities.The narrative, social, and pragmatic language skills of school-aged bilinguals (n = 54) and monolinguals (n = 80) on the AS were assessed using normed measures. Language exposure was estimated through a parent questionnaire.Bilinguals performed similarly to monolinguals on measures of narrative, social, and pragmatic language skills. However, balanced bilinguals performed better on a nonliteral language task.Overall, results indicate that bilingual children on the AS can become as proficient in using language as monolinguals and may enjoy a bilingual advantage.

Bilingualism in School-Aged Children with ASD: A Pilot Study.

Preschool-aged bilingual children with autism spectrum disorder (ASD) can keep pace with their monolingual peers with ASD. However, can older children with ASD continue to do so as language demands become greater? Also, can they reach language levels similar to those of neurotypically developing (ND) bilingual children? The current study compares the language abilities of 3 school-aged bilingual children with ASD to those of 2 monolingual peers, and 19 ND bilingual and 12 ND monolingual peers. Using cluster analyses, we found that bilingual children with ASD had similar language to those of monolingual children with ASD and neurotypically developing bilingual and monolingual children. Results suggest that bilingual children with ASD can keep pace with their peers with similar intellectual abilities.

English Verb Accuracy of Bilingual Cantonese-English Preschoolers.

Purpose: Knowledge of verb development in typically developing bilingual preschoolers may inform clinicians about verb accuracy rates during the 1st 2 years of English instruction. This study aimed to investigate tensed verb accuracy in 2 assessment contexts in 4- and 5-year-old Cantonese-English bilingual preschoolers. Method: The sample included 47 Cantonese-English bilinguals enrolled in English preschools. Half of the children were in their 1st 4 months of English language exposure, and half had completed 1 year and 4 months of exposure to English. Data were obtained from the Test of Early Grammatical Impairment (Rice & Wexler, 2001) and from a narrative generated in English. Results: By the 2nd year of formal exposure to English, children in the present study approximated 33% accuracy of tensed verbs in a formal testing context versus 61% in a narrative context. The use of the English verb BE approximated mastery. Predictors of English third-person singular verb accuracy were task, grade, English expressive vocabulary, and lemma frequency. Conclusions: Verb tense accuracy was low across both groups, but a precocious mastery of BE was observed. The results of the present study suggest that speech-language pathologists may consider, in addition to an elicitation task, evaluating the use of verbs during narratives in bilingual Cantonese-English bilingual children.

Narratives in Two Languages: Storytelling of Bilingual Cantonese-English Preschoolers.

PURPOSE: The aim of this study was to compare narratives generated by 4-year-old and 5-year-old children who were bilingual in English and Cantonese. METHOD: The sample included 47 children (23 who were 4 years old and 24 who were 5 years old) living in Toronto, Ontario, Canada, who spoke both Cantonese and English. The participants spoke and heard predominantly Cantonese in the home. Participants generated a story in English and Cantonese by using a wordless picture book; language order was counterbalanced. Data were transcribed and coded for story grammar, morphosyntactic quality, mean length of utterance in words, and the number of different words. RESULTS: Repeated measures analysis of variance revealed higher story grammar scores in English than in Cantonese, but no other significant main effects of language were observed. Analyses also revealed that older children had higher story grammar, mean length of utterance in words, and morphosyntactic quality scores than younger children in both languages. Hierarchical regressions indicated that Cantonese story grammar predicted English story grammar and Cantonese microstructure predicted English microstructure. However, no correlation was observed between Cantonese and English morphosyntactic quality. CONCLUSIONS: The results of this study have implications for speech-language pathologists who collect narratives in Cantonese and English from bilingual preschoolers. The results suggest that there is a possible transfer in narrative abilities between the two languages.

Improving Preschool Educators' Interactive Shared Book Reading: Effects of Coaching in Professional Development.

PURPOSE: The objective of this study was to examine the effects of coaching by speech-language pathologists on educators' interactive shared book reading, children's participation in shared reading, and children's language development. METHOD: Thirty-two educators and small groups of preschoolers were randomly assigned to experimental and comparison groups. The experimental group (n = 15) received 4 in-service workshops plus 5 individualized coaching sessions. The comparison group received only the 4 workshops. Participants were video-recorded during a shared book reading activity with a small group of children at pretest and posttest. The video recordings were transcribed and coded to yield measures of conversations, educators' questions, and children's responses. The mean length of utterances of the children's responses was also calculated. RESULTS: There were no significant Time × Group interaction effects for the number and length of shared reading conversations or for the number of participants in these conversations. However, significant Time × Group interactions were observed for the use of educators' experiential reasoning questions, children's experiential reasoning responses, and the mean length of utterances of children's responses. CONCLUSION: These results suggest that coaching increases educators' use of inferential questions, enhancing an interactive shared-reading strategy that had a direct impact on the children's quality and complexity of language.

Oral narratives in monolingual and bilingual preschoolers with SLI.

BACKGROUND: The body of literature on narratives of bilingual children with and without specific language impairment (SLI) is growing. However, little is known about the narrative abilities of bilingual preschool children with SLI and their patterns of growth. AIMS: To determine the similarities and differences in narrative abilities between preschoolers with and without SLI who are either monolingual or bilingual at two time points. METHODS & PROCEDURES: Forty children completed a narrative retell task in English at two test points. The mean ages were 52 and 58 months at Times 1 and 2, respectively. We examined performance on measures of narrative macrostructure (narrative information) and microstructure (sentence length, number of different words, verb accuracy, first mentions) in monolingual and bilingual children with and without SLI. The bilingual children were from diverse first-language backgrounds and all spoke English most of the time. OUTCOMES & RESULTS: A series of repeated-measures analyses of variance was used with language ability (typical development or SLI) and bilingual status (monolingual versus bilingual) as the between-subjects factors and time (Times 1 or 2) as the within-subjects factor. Results indicated a significant main effect of time for four measures (i.e., Information Score, lexical diversity, sentence length and verb accuracy). The between-subjects analyses indicated a significant difference between the typically developing children and the children with SLI in all measures and a significant difference between monolingual and bilingual children for verb accuracy only. CONCLUSIONS & IMPLICATIONS: This study showed that all four groups of children showed growth over a 6-month period and that bilingual children exposed predominantly to English in the home performed similarly to their monolingual peers in measures of narrative information, sentence length, number of different words and first mentions.

Maternal recasts and activity variations: a comparison of mother-child dyads involving children with and without SLI.

This study investigated maternal recast and the children's responses comparing dyads made up of a mother and a child with typical language development (TD) or a child with specific language impairment (SLI). More specifically, this article deals with the influence of the type of activity being carried out on the number and types of maternal recasts. A sample of 17 French-speaking children with SLI (age 5 to 7 years) matched with 17 TD same-age peers was observed in interaction with their mother during four different activities (joint reading, symbolic play, question guessing game and clue guessing game). The results showed that group and activity had an impact on the number and type of recasts. Mothers of children with SLI offered more recasts than mothers of TD children. The former preferred phonological recasts whereas the latter preferred lexical ones. Moreover, recasts were more frequently used in joint reading than in other activities. Regarding the children's responses, no significant difference was observed between the two groups. Children with SLI took up the maternal proposition more frequently after a lexical recast than after a recast of another type. The findings provide evidence for considering the features of the activities in clinical settings.

Family-level covariation between parasite resistance and mating system in a hermaphroditic freshwater snail.

Genetic compatibility, nonspecific defenses, and environmental effects determine parasite resistance. Host mating system (selfing vs. outcrossing) should be important for parasite resistance because it determines the segregation of alleles at the resistance loci and because inbreeding depression may hamper immune defenses. Individuals of a mixed mating hermaphroditic freshwater snail, Lymnaea ovata, are commonly infected by a digenetic trematode parasite, Echinoparyphium recurvatum. We examined covariation between quantitative resistance to novel parasites and mating system by exposing snail families from four populations that differed by their inbreeding coefficients. We found that resistance was unrelated to inbreeding coefficient of the population, suggesting that the more inbred populations did not carry higher susceptibility load than the less inbred populations. Most of the variation in resistance was expressed among the families within the populations. In the population with the lowest inbreeding coefficient, resistance increased with outcrossing rate of the family, as predicted if selfing had led to inbreeding depression. In the other three populations with higher inbreeding coefficients, resistance was unrelated to outcrossing rate. The results suggest that in populations with higher inbreeding some of the genetic load has been purged, uncoupling the predicted relationship between outcrossing rate and resistance. Snail families also displayed crossing reaction norms for resistance when tested in two environments that presented low and high immune challenge, suggesting that genotype-by-environment interactions are important for parasite resistance.
