Acceleration in the bilingual acquisition of phonological structure: evidence from Polish–English bilingual children

This study examines the production of consonant clusters in simultaneous Polish-English bilingual children and in language-matched English monolinguals (aged 7;01- 8;11). Selection of the language pair was based on the fact that Polish allows a greater range of phonologically complex cluster types than English. A nonword repetition task was devised in order to examine clusters of different types (obstruent-liquid vs. s + obstruent) and in different word positions (initial vs. medial), two factors that play a significant role in repetition accuracy in monolingual acquisition (e.g. Kirk & Demuth, 2005). Our findings show that bilingual children outperformed monolingual controls in the word initial s + obstruent condition. These results indicate that exposure to complex word initial clusters (in Polish) can accelerate the development of less phonologically complex clusters (in English). This constitutes significant new evidence that the facilitatory effects of bilingual acquisition extend to structural phonological domains

Language non-selective syntactic activation in early bilinguals: the effect of verbal fluency

Numerous studies have shown that bilinguals presented with words in one of their languages spontaneously and automatically activate lexical representations from their other language. However, such effects, found in varied experimental contexts, both in behavioural and psychophysiological investigations, have been essentially limited to the lexical-semantic domain. Using brain potentials in a mental decision task in early highly proficient Welsh�English bilinguals and English monolingual controls, a recent study suggests that language non-selective effects exist in the domain of syntax. In this paper, we test whether syntactic access in bilinguals is affected by relative language abilities, as indexed by verbal fluency measures in the bilingual's two languages. Results reveal that non-selective syntax in English sentence comprehension is limited to bilinguals with higher Welsh verbal fluency. This result suggests for the first time directionality in cross-language syntactic activation in early bilinguals

Pronoun comprehension in individuals with Down syndrome: The role of age

Background A number of studies have suggested that language in individuals with Down syndrome (DS) may not be simply delayed compared with language in typically developing (TD) children, but deviant. The deviance has been detected in the comprehension of pronouns, and it has triggered proposals for the existence of a specific syntactic deficit in individuals with DS. However, the developmental path of pronoun comprehension in individuals with DS is unknown as there are no studies examining individuals of different ages. Aims To perform a pilot study examining pronoun comprehension in adolescents and adults with DS in comparison with TD children. Research questions include: Are some pronoun types more difficult than others for each of the two groups (DS and TD)? Is there a difference in performance between the two groups? Does performance correlate with chronological age in the DS group? Methods & Procedures Using a manual picture selection task, we examined the comprehension of different types of pronouns in 14 Greek-speaking individuals with DS, ranging from 10 to 34 years of age. We also tested a control group of TD children as well as a typical adult group. The TD and DS groups were recruited and tested in pre-schools and schools/centres for individuals with learning disabilities, respectively. Within- and between-group comparisons were performed for all conditions. For the DS group, correlations between chronological age and performance in each condition were also explored. Outcomes & Results Results reveal a significant positive correlation of age with performance in the DS group, but only in structures that also presented difficulties to TD children. Structures that presented difficulties only to individuals with DS do not appear to be less problematic for older participants. Conclusions & Implications These findings provide support to the deviance hypothesis by suggesting that the syntactic deficit in the comprehension of pronouns in individuals with DS is present in individuals of a wide age range. At the same time, the results, if corroborated by large-scale studies, suggest that some aspects of grammatical development in individuals with DS may continue even after adolescence and well into adulthood. We argue that these findings can contribute towards more targeted intervention practices by increasing our knowledge of the behavioural phenotype of DS. © 2014 Royal College of Speech and Language Therapists

Task Effects in the Interpretation of Pronouns

Children acquiring a range of languages have difficulties in the interpretation of personal pronouns. Ongoing debates in the relevant literature concern the extent to which different pronoun types are subject to this phenomenon, as well as the role of methodology in relevant research. In this study, we use two different experimental tasks to examine the interpretation of pronominal elements in Greek, a language that has both strong pronouns and pronominal clitics. Results reveal a complete absence of problems in the interpretation of clitics irrespective of task. However, there were task effects in the comprehension of strong pronouns in both children and adults. Findings indicate that the phenomenon is intrinsically linked to the properties of the elements in question. Analysis of the task effects highlights how different methodological manipulations can shed light on different properties of the elements studied. © , Copyright © Taylor & Francis Group, LLC

Pronoun comprehension in individuals with down syndrome: Deviance or delay?

Purpose: Results of recent pilot studies suggest that the interpretation of pronouns in individuals with Down syndrome (DS) may follow a pattern unattested in typical development, indicating the presence of a selective deficit targeting the comprehension of reflexive pronouns. These findings come at a time when there is a heated debate surrounding pronoun comprehension in typical development as well. This study aims to contribute to these debates by examining pronoun comprehension in Greek, a language that exhibits unusual patterns in pronoun comprehension in typical development. Method: Seven Greek-speaking individuals with DS and a control group of 14 typically developing (TD) children were tested. The authors examined the comprehension of strong pronouns, reflexive pronouns, and pronominal clitics, using a picture selection task. Results: The data reveal evidence of deviant pronoun comprehension in individuals with DS compared with theTD group. The DS group encountered problems in the interpretation of reflexive pronouns when compared with the TD group, while the performance of the two groups was comparable in all remaining conditions. Conclusions: Findings are in line with the selective deficit model of language comprehension in DS, supporting the presence of a cross-linguistic reflexive deficit. © American Speech-Language-Hearing Association
