Short vita

(for a longer, downloadable CV, see below)

 

I am a linguist specializing in language acquisition by typical, impaired, and multilingual populations. I earned my MA degree from Utrecht University in 1990, my PhD degree from UCLA in 1997, and was a Postdoc at MIT until 1998. From 1998-2011 I worked at Ben Gurion University in Israel as an Assistant and an Associate Professor. I have been affiliated with the University of Amsterdam since 2011.

 

Research interests

My research varies from the study of language acquisition by typically developing monolingual Dutch-, English-, Italian-, Hebrew-, and Russian-acquiring children, to multilingualism (including L2) and the study of language disorders, particularly in individuals with Specific Language Impairment, Autism Spectrum Disorder, and Hemispherectomy.

The recurring theme in my research is the question as to whether grammar and pragmatics are two separate language components or not, and what their respective roles and interaction are in language development. The linguistic phenomena I investigate to this end include object scrambling, clitic placement, Wh-movement, article drop, article choice, the mass/count distinction, subject drop, subject-verb agreement, Root Infinitives, Case, implicatures. Besides using behavioral experimental techniques, I also have a special interest in brain-imaging and electrophysiological techniques to collect data.

Grammar and Pragmatics in Specific Language Impairment and Autism Spectrum Disorder

 

Period: March 2012 - March 2014

 

In this project we investigate grammatical and pragmatic development in Dutch-speaking children with Specific Language Impairment (SLI), Dutch-speaking children with Autism Spectrum Disorder (ASD), and typically developing (TD) monolingual Dutch-speaking children between the ages of 6 and 12 years old.  The goal of the project is to find a double dissociation between grammar and pragmatics. As for the grammatical phenomena, we examine subject-verb agreement / finiteness and the mass/count distinction. The pragmatic phenomena under consideration are article choice and direct object scrambling. To collect data, we use elicited production tasks, comprehension tasks, and judgment tasks. Hypothesizing that children with SLI are mainly impaired in their grammar, but not in their pragmatics, I predict that they perform well on article choice and direct object scrambling, but that they make more errors than their age mates on subject-verb agreement / finiteness and the mass/count distinction. Furthermore, hypothesizing that children with ASD are mainly impaired in their pragmatics, but not in their grammar, I predict that they perform well on subject-verb agreement / finiteness and the mass/count distinction, but that they make more errors than their age mates on article choice and direct object scrambling. If the predictions are borne out, the results would provide support for the domain specificity of grammar vs. pragmatics.

 

Currently, two students participate in this research project:

Merel van Witteloostuijn - rMA student Linguistics, Utrecht University

Leanne Matimba - BA student Linguistics, University of Amsterdam
