Modelling Vocabulary Loss
University of Wales Swansea
This paper describes some simple simulation models of vocabulary attrition. The attrition process is modelled using a random autonomous Boolean network model, and some parallels with real attrition data are drawn. The paper argues that applying a complex systems approach to attrition can provide some important insights, which suggest that real attrition data may need to be treated with caution. It concludes that simulation methodsa technique that is not widely used in applied linguistic researchmay be able to throw interesting new light on attrition, and provide a way of examining some of the assumptions that we take for granted in attrition experiments with human subjects.
