Missing Surface Inflection or Impairment in Second Language Acquisition? Evidence from Tense and Agreement.

In this article, two accounts of the variable use of inflection in adult second language (L2) acquisition are examined. The Missing Surface Inflection Hypothesis (MSIH) proposes that L2 learners have unconscious knowledge of the functional projections and features underlying tense and agreement. However, learners sometimes have a problem with realization of surface morphology, such that they resort to non-finite forms (e.g. Haznedar and Schwartz, 1997; Prévost and White, 1999). The Impaired Representation Hypothesis (IRH) claims that L2 inflection is essentially impaired, due to lack of functional categories, features or feature strength (e.g. Eubank, 1993/94; Meisel, 1997). These views make different predictions for adult L2 acquisition. Spontaneous production data from two adult learners of French and two adult learners of German are examined. The data show that finite forms do not occur in non-finite contexts, that learners exhibit syntactic reflexes of finiteness and that inflected forms largely show accurate agreement. These results suggest that adult L2 learners represent finiteness and agreement at an abstract level, rather than being impaired in this domain, supporting the MSIH.

The acquisition of French : the development of inflectional morphology and syntax in L1 acquisition, bilingualism, and L2 acquisition

This book presents a thorough description of morphosyntactic knowledge developed by learners of French in four different learning situations — first language (L1) acquisition, second (L2) language acquisition, bilingualism, and acquisition by children with Specific Language Impairment — within the theoretical framework of generative grammar. This approach allows for multiple comparisons across acquisition contexts, which provides the reader with invaluable insights into the nature of the acquisition process. The book is divided into four parts each dealing with a major morphosyntactic domain of acquisition: the verbal domain, the pronominal domain, the nominal domain, and the CP domain. Each part contains four chapters, the first one presenting an overview of the basic facts and analyses of the relevant properties of French, and the next three focusing on the different acquisition contexts. This book will be useful to anyone interested in the acquisition of French and in language development in general. It is also meant to stimulate cross-linguistic research from a theoretical perspective.

Mood Selection in Relative Clauses: Interfaces and Variability.

There is presently a lively debate in second language (L2) acquisition research as to whether (adult) learners can acquire linguistic phenomena located at the interface between syntax and other modules, such as semantics, pragmatics, and lexical semantics, in contrast to phenomena that are purely syntactic in nature. For some researchers, the interface is precisely the place where fossilization occurs and the source of nonconvergence in L2 speakers. In this article we focus on the acquisition of the morphosyntax-semantics interface by examining the acquisition of mood in Spanish relative clauses by native speakers (NSs) of English. In particular, we focus on the contrast illustrated by Busco unas tijeras que corten “I am looking for scissors that cut- subj ” versus Busco unas tijeras que cortan “I am looking for scissors that cut- ind .” When the indicative is used, there is a specific pair of scissors that the speaker is looking for. With the subjunctive, any pair of scissors will do, as long as it satisfies the condition expressed by the relative clause; the determiner phrase is nonspecific. In other words, we are dealing not with ungrammaticality, as both moods are possible in these contexts, but rather with differences in interpretation. General results showed that the learners could appropriately select the expected mood. We also saw that performance was not uniform across the various conditions tested. However, variability is not solely a product of L2 acquisition; we show it can be found in NSs as well.

How to identify SLI in bilingual children: A study on sentence repetition in French

ABSTRACT Identifying specific language impairment (SLI) in bilingual children represents a clinical challenge because of similarities in language behavior between child second language learners and monolinguals with SLI and because of the lack of standardized language tests on bilingual children. This study investigated the relevance of a LITMUS (Language Impairment Testing in Multilingual Settings) sentence repetition (SR) task based on language properties difficult for French-speaking children with SLI for the diagnosis of language impairment in bilinguals. The task was administered to 47 bilingual children aged 5;02 to 8;09, 35 with typical development (TD) and 12 with SLI, and to 50 monolingual controls (37 with TD and 13 with SLI). Percentage of identical repetition significantly distinguished between children with SLI and children with TD in both bilinguals and monolinguals and on all structure types. Moreover, no correlations were found between factors of bilingual development, such as age of onset, length of exposure, and quantity and quality of input, and the low repetition rates of the bilingual children with SLI, suggesting that the LITMUS-SR-French task can be used as an efficient diagnosis tool in bilinguals.

Wh-questions in child L2 French: Derivational complexity and its interactions with L1 properties, length of exposure, age of exposure, and the input

This study investigates how derivational complexity interacts with first language (L1) properties, second language (L2) input, age of first exposure to the target language, and length of exposure in child L2 acquisition. We compared elicited production of wh-questions in French in two groups of 15 participants each, one with L1 English (mean age 8 years 10 months or 8;10) and one with L1 Dutch (mean age 6;3), which were further subdivided into subgroups matched for the different variables under examination. Although in their L1s wh-questions display wh-movement and subject–verb/aux inversion, the learners did not perform similarly. A high number of wh-in-situ questions (i.e. the least complex option) was produced by the L1-English children, suggesting that derivational complexity can override L1 influence. In the L1-Dutch group, questions with overt wh-movement were more frequent. This may stem from the influence of generalized XP-movement to the left periphery in Dutch. Inversion (i.e. the most complex option) was rare in both groups and was related to contact with formal schooling. These results hold across the different subgroups, which suggests not only that complexity plays a role in child L2 acquisition, but also that its effects may differ according to the properties of the L1.

Identifying language impairment in bilingual children in France and in Germany: Language impairment in bilingual children

BACKGROUND The detection of specific language impairment (SLI) in children growing up bilingually presents particular challenges for clinicians. Non-word repetition (NWR) and sentence repetition (SR) tasks have proven to be the most accurate diagnostic tools for monolingual populations, raising the question of the extent of their usefulness in different bilingual populations. AIMS To determine the diagnostic accuracy of NWR and SR tasks that incorporate phonological/syntactic complexity as discussed in recent linguistic theory. The tasks were developed as part of the Language Impairment Testing in Multilingual Settings (LITMUS) toolkit, in two different national settings, France and Germany, and investigated children with three different home languages: Arabic, Portuguese and Turkish. METHODS & PROCEDURES NWR and SR tasks developed in parallel were administered to 151 bilingual children, aged 5;6-8;11, in France and in Germany, to 64 children in speech-language therapy (SLT) and to 87 children not in SLT, whose first language (L1) was Arabic, Portuguese or Turkish. Children were also administered standardized language tests in each of their languages to determine likely clinical status (typical development (TD) or SLI), and parents responded to a questionnaire including questions about early and current language use (bilingualism factors) and early language development (risk factors for SLI). Monolingual controls included 47 TD children and 29 children with SLI. Results were subjected to inter-group comparisons, to diagnostic accuracy calculation, and to correlation and multiple regression analyses. OUTCOMES & RESULTS In accordance with previous studies, NWR and SR identified SLI in the monolingual children, yielding good to excellent diagnostic accuracy. Diagnostic accuracy in bilingual children was fair to good, generally distinguishing children likely to have SLI from children likely to have TD. Accuracy was necessarily linked to the determination of clinical status, which was based on standardized assessment in each of the childs languages. Positive early development, a composite risk factor for SLI, and not variables related to language exposure and use, generally emerged as the strongest predictor of performance on the two tasks, constituting additional, independent support for the efficacy of NWR and SR in identifying impairment in bilingual children. CONCLUSIONS & IMPLICATIONS NWR and SR tasks informed by linguistic theory are appropriate for use as part of the diagnostic process for identifying language impairment in bilingual children for whom the language of assessment is different from the home language, in diverse sociolinguistic contexts.

Production and comprehension of French wh-questions by children with autism spectrum disorder: A comparative study with specific language impairment: CORRIGENDUM

The nature of structural language difficulties in children with autism spectrum disorder (ASD) was explored in a comparative study with specific language impairment (SLI) through investigation of the frequently reported ASD weakness in receptive skills relative to expressive skills. Twenty French-speaking children with ASD aged 6 to 12 were compared to age-matched children with SLI on production and comprehension of wh-questions. The two groups displayed similar effects of the complexity of the different wh-strategies. In the ASD group (as in the SLI group), these effects were not greater in comprehension compared to production; moreover, nonverbal ability (which varied from normal to impaired) was not related to language performance. Observed ASD-SLI differences are argued to largely be due to ASD pragmatic deficits, rather than to a qualitative difference in structural language skills.

Pragmatic versus structural difficulties in the production of pronominal clitics in French-speaking children with autism spectrum disorder

Background and aims Impaired production of third person accusative pronominal clitics is a signature of language impairment in French-speaking children. It has been found to be a prominent and persistent difficulty in children and adolescents with specific language impairment. Previous studies have reported that many children with autism spectrum disorder also have low performance on these clitics. However, it remains unclear whether these difficulties in children with autism spectrum disorder are due to structural language impairment or to pragmatic deficits. This is because pragmatics skills, notoriously weak in children with autism spectrum disorder, are also needed for appropriate use of pronouns. Use of pronouns without clear referents and difficulty with discourse pronouns (first and second person), which require taking into account the point of view of one’s interlocutor (perspective shifting), have frequently been reported for autism spectrum disorder. Methods We elicited production of nominative, reflexive and accusative third and first person pronominal clitics in 19 verbal children with autism spectrum disorder (aged 6–12, high and low functioning, with structural language impairment, or with normal language) and 19 age-matched children with specific language impairment. If pragmatics is behind difficulties on these elements, performance on first-person clitics would be expected to be worse than performance on third person clitics, since it requires perspective shifting. Furthermore, worse performance for first person clitics was expected in the children with autism spectrum disorder compared to the children with specific language impairment, since weak pragmatics is an integral part of impairment in the former, but not in the latter. More generally, different error patterns would be expected in the two groups, if the source of difficulty with clitics is different (a pragmatic deficit vs. a structural language deficit). Results Similar patterns of relative difficulties were found in the autism spectrum disorder language impairment and specific language impairment groups, with third person accusative clitics being produced at lower rates than first-person pronouns and error patterns being essentially identical. First-person pronouns did not pose particular difficulties in the children with autism spectrum disorder (language impairment or normal language) with respect to third-person pronouns or to the children with specific language impairment. Performance was not related to nonverbal intelligence in the autism spectrum disorder group. Conclusions The elicitation task used in this study included explicit instruction, and focus on perspective shifting (both visual and verbal), allowing for potential pragmatic effects to be controlled. Moreover, the task elicited a variety of types of clitics in morphosyntactic contexts of varying complexity, providing ample opportunities for employment of perspective shifting, which may have also curtailed perseveration of third person over first person. These properties of the task allowed for the grammatical nature of children’s difficulties with third-person accusative clitics to emerge unambiguously. Implications Assessment of structural language abilities in children with autism spectrum disorder requires careful consideration of task demands. The influence of pragmatic abilities on structural language performance can be circumvented by making the pragmatic demands of the task explicit and salient. Filtering out this potential influence on structural language performance is fundamental to understanding language profiles in children with autism spectrum disorder and thus which children could benefit from which kinds of language intervention.

A strategic plan to identify key neurophysiological mechanisms and brain circuits in autism

Autism and Autism Spectrum Disorder (ASD) cover a large variety of clinical profiles which share two main dimensions: social and communication impairment and repetitive behaviors or restricted interests, which are present during childhood. There is now no doubt that genetic factors are a major component in the etiology of autism but precise physiopathological pathways are still being investigated. Furthermore, developmental trajectories combined with compensatory mechanisms will lead to various clinical and neurophysiological profiles which together constitute this Autism Spectrum Disorder. To better understand the pathophysiology of autism, comprehension of key neurophysiological mechanisms and brain circuits underlying the different bioclinical profiles is thus crucial. To achieve this goal we propose a strategy which investigates different levels of information processing from sensory perception to complex cognitive processing, taking into account the complexity of the stimulus and whether it is social or non-social in nature. In order to identify different developmental trajectories and to take into account compensatory mechanisms, we further propose that such protocols should be carried out in individuals from childhood to adulthood representing a wide variety of clinical forms.

A review of four books introducing the Minimalist Program

Although Minimalism is often referred to as a program, it is now sufficiently developed to be an indisputable part of the discussion in theoretical syntax and even the subject of introductory manuals. The four books reviewed in this article each reflect the place Minimalism now holds in linguistic theory. They can be divided into two groups, depending on the intended readership. Radford’s and Ouhalla’s volumes are introductions to theoretical syntax and can be read with no linguistic background. The two other books are much more technical and address more advanced readers. Each group can be further subdivided according to whether Minimalism is presented from an historical perspective or discussed ‘in its own right’.
