Areas of expertise
My primary research interest is the way verbal short-term memory is supported by speech and language processing skills. In the case of speech, the general aim has been to identify the way acoustic, prosodic and lexical components form a multi-layered representation that allows us to reproduce a sequence of words immediately after it is heard. I have collaborated with Beth Jefferies (York) and Annabel Thorn (Bristol), investigating how short term memory is supported by knowledge of vocabulary and rules that determine how sounds may be combined to form words in a particular language. My research on reading has shown how perception of wordlike letter strings is influenced by the integration of visual processing with reading mechanisms that automatically create a representation of the corresponding spoken form.
I have worked extensively on aspects of human-computer interaction, with a particular focus on the design of "naturalistic" interfaces involving speech or handwriting recognition.
