In the last twenty years, the empirical and theoretical research on language change on the one hand and on first and second language acquisition on the other has literally exploded. Nowadays, both can be considered in their own right as two of the well established and most fruitful empirical domains of investigation. In both domains experimental methods and statistical evaluation procedures have been standardized and the results obtained have deeply increased what we know about language.
Since language change is related to language acquisition, the object of investigation of both fields is virtually the same. However, there has been relatively little contact between researchers working in the two domains. The aim of this workshop is to compare methods but above all theoretical founding assumptions to reach a better understanding of the procedure according to which language develops, both in the individual and across generations.
