Helen to present her PhD research at Interspeech 2011

Posted on 22 June 2011

Helen Brown has recently had an oral presented accepted at the Interspeech 2011 conference.

Helen will present her PhD research on talker-specificity effects for newly-learned pseudowords, supervised by Gareth Gaskell. Click here for more information on Interspeech 2011. Here is Helen's abstract:

The time-course of talker-specificity effects for newly-learned pseudowords: Evidence for a hybrid model of lexical representation

Whilst research shows that talker information affects recognition of recently studied words, it remains unclear whether this information is stored in long-term memory. Three experiments explored whether talker-specificity effects (TSEs) for pseudowords changed over time and were affected by within- and between-talker variability during study. Results showed TSEs immediately after study in all experiments, consistent with episodic models, but TSEs remained a week later only for pseudowords studied in a single voice. Furthermore, source memory data suggested that talker information becomes less accessible over time, supporting hybrid models that incorporate aspects of both episodic and abstract lexical representation.
