This work has been fun on so many levels. First, it connects my current research with my very early experiences with language sciences. Williams syndrome was often used as an example to illustrate how language functions as an independent cognitive “module” - or, even better, an “organ” - which doesn’t always behave like other functions of the brain/mind. I was academically raised with that belief, and now it was time to scrutinize it.

Second, the people with whom I worked were fantastic. This paper is based on a secondary data analysis conducted by two then-final-year undergraduate students, Ioana Sederias and Ariane Krakovitch, who I supervised. These were the years of the Covid lockdowns - dark and stressful at least for me - and working with these two smart and fun students was one of the few bright spots during that time.

Finally, the project itself went remarkably smoothly. Our predictions came naturally from previous observations and the data supported them strongly. Some confused head-scratching is fairly typical when one first looks at results, but not here. The data tell a very clear story. And this is the story:

Artificial grammar learning in Williams syndrome and in typical development: The role of rules, familiarity, and prosodic cues.

I heard about Williams syndrome (WS) for the first time when I was a linguistics student in Düsseldorf. The genetic disorder was interesting for one perceived dissociation: People with WS, so the view, had typical language capacities, but impairments of general cognitive abilities, demonstrating that the language system was independent, modular in the sense of (early) Chomsky and Jerry Fodor. Today we know this to be wrong. The language in WS may appear typical at a quick glance, but there are production as well as comprehension deficits, especially at a grammatical level. This study, led by Vesna Stojanovik at the University of Reading, aimed to understand what underlies the language profile in WS.
