Tilburg center for Cognition and Communication (TiCC)

We study how people communicate with each other and how computer systems can be taught to communicate with us.


TiCC Colloquium: Emmanuel Keuleers

What: The lab has left the building: What mass behavioral experiments tell us about vocabulary and lexical processing
Where: TZ 005
When: Wednesday, 2 March 2016, 12:30 - 13:30 hours


In this talk, I will present some results of a series of currently running studies in which data from hundreds of thousands of participants were collected. I will briefly discuss how we used participant engagement strategies to adapt the lexical decision task ‒ a traditional experimental method used in psycholinguistics ‒ for online testing of vocabulary size and lexical processing. Then, I will focus on two substantial empirical findings from these data: (1) vocabulary size shows logarithmic growth with age according to Herdan's law, and (2) L1 vocabulary size is shown to increase with additional languages known. Both these findings have profound implications for research and theories about aging, vocabulary testing and multilingualism. Finally, I will present initial results demonstrating how the large datasets obtained using these methods can be used to study differences between vocabulary in different regions and how effects of historical language policies in different areas are reflected in the data.
