 Typological variations in the acquisition of relative clauses: evidence from child Cantonese

Relative clause (RC) is a widely recognized topic of investigation in the fields of language typology, acquisition and processing. The Noun Phrase Accessibility Hierarchy (NPAH, a “putative” linguistic universal) has a long history in accounting for the acquisition of RCs in European languages. Recently however, conceptual changes in rethinking the typology of RCs and child language data from certain Asian languages led researchers of language acquisition to question how far NPAH could account for the learning patterns observed. For instance, Chen & Shirai (2014) hypothesized that in attributive clause languages, multiple factors including input frequency and similarity to canonical clauses, rather than purely structure-based accounts, determine the learning trajectory of RCs. Currently, there is little direct testing of these competing theoretical perspectives. Thus far the evidence from child first acquisition of attributive clause languages (e.g. Japanese, Mandarin, Cantonese) suggesting that the developmental patterns do not follow predictions from NPAH is largely based on naturalistic speech production or comprehension data which have their own methodological limitations.

As an attributive clause language, Cantonese provides an interesting test case. In this talk, I will first review the current literature including recent and ongoing works by myself and collaborators, highlighting phenomena of apparent conflicting findings (or “variations”) that also happen in other Asian attributive clause languages, but appear to rarely occur in European languages. I will then outline a proposed project that uses multiple methods to better test the alternative theoretical perspectives. The findings offer a rich testing ground to evaluate a range of theoretical perspectives. An important innovation of the proposed project is the extension of experimental studies to not only Cantonese, and eventually to other attributive clause languages such as Japanese, Mandarin and Thai. Moreover, computational linguists can make use of these new datasets to model the acquisition and processing of RCs in attributive clause languages. The project will broaden and deepen our understanding of RC acquisition/processing in an Asian linguistic context.

Speech disorders in Huntington´s disease, Sydenham’s chorea and Neuroacanthocytosis
Tiago Attoni
Postdoc Fellow at the LPL (w/ Serge Pinto)
The basal ganglia are related classically to motor functions, being referred as the extra-pyramidal system. The assumed importance of these structures is seen in motor performance disorders as in Huntington’s disease, Sydenham’s chorea and Neuroacanthocytosis, whose common trait changes in the functioning of the basal ganglia. Speech motor disorders are reported as a common sign at the three diseases, characterized as hyperkinetic dysarthria which occurs mainly as a consequence of choreatic movements. The quality of speech performance is negatively affected by the involuntary contractions of vocal muscles, with incoordination of the jaw, tongue, palate, and facial movements. Thus, the aim current study was to examine principal disturbances of speech presented in the literature for these three diseases. In addition, the new study prospects of the Brazilian group.

Preserving and sharing linguistic resources with SLDR/ORTOLANG

November, 3, 2014

Linguistic data include recorded or written corpora, their annotations/analyses, lexical and grammatical resources, and tools for the display and processing of diverse forms of data. The main challenge of designing a repository and associated curation procedures lies in putting a minimum set of constraints on the data produced by a research project, and altogether allowing its long-term preservation for usage by other teams. To this effect, the repository should create an extensive amount of descriptive metadata in standard formats, persistent identifiers targetting fine-grain content, and an integrated management of access rights complying with the consent of project participants and the legal context of the archive.

We will describe these steps in the current SLDR/ORTOLANG framework, taking as an example the creation and curation of a speech corpus.
