Research Summary
My research interests include language processing, phonological and lexical development, and category learning. My research includes experimental studies and mathematical models of people's perception of similarity relationships, and of their ability to generalize knowledge acquired by limited experience to interpret and produce novel patterns.
How do English speakers decide whether novel words like pokami should be pronounced POkami, poKAmi, or pokaMI? Which pair sounds more similar, dog-cog or dog-dot, and why? When people encounter new objects and learn that this is a dax and that is a neem, how do they decide whether a third item is a dax or a neem? These are some of the questions my research addresses.

Biography
Undergraduate Education
I received my undergraduate degree (BSc Computer Science with Distinction) from the University of Minnesota, USA, in 1983. I subsequently developed computer-aided engineering instruments at Hewlett-Packard in Colorado Springs, Colorado, USA.
Postgraduate Education
I studied linguistics and cognitive science at the University of Minnesota from 1989 under the supervision of Professor Joseph Stemberger, and obtained an MA in 1993 and a PhD in 1995. During this time I was affiliated with the Center for Research in Learning, Perception and Cognition, and I enjoyed a Graduate Traineeship sponsored by the National Institute of Child Health and Human Development (1993-94). My thesis examined patterns of primary word stress across many languages and considered the mental representations required to learn and generalize various attested patterns and accommodate lexical exceptions. I also achieved a certificate in Spanish language proficiency.
Employment
worked with Professor Kim Plunkett in the McDonnell-Pew Centre for Cognitive Neuroscience and the Department of Experimental Psychology at Oxford University from 1996 to 2000, studying phonological and lexical development in very young children. Establishing collaborations with Ulrike Hahn and Emmanuel Pothos, I also broadened my interest in categorisation and developed an interest in what it means for things to seem similar.
I took up my current post at Cardiff University in 2000. Lewis Bott and I have recently obtained research council funding to examine the time course of understanding literal and non-literal sentence meanings. Also, the Welsh Institute of Cognitive Neuroscience has helped to identify possibilities for collaboration with colleagues in Bangor, resulting in WICN grants to look at brain activity associated with phonological processing in monolingual and bilingual children (with Debbie Mills), to study memory for words using repetition priming (with Stephen Boehm), and to examine brain activity evoked by sentences describing the temporal order of events (with Lewis Bott, Ed Wilding, and Guillaume Thierry).
