Intra–individual Variation in Language

Which linguistic and extra-linguistic factors explain intra-individual variation? Is there observable intra-individual variation that cannot be explained by linguistic and extra-linguistic factors? Can group-level results be generalised to individual language usage and vice versa? Is intra-individual variation indicative of actual patterns of language change? How can intra-individual variation be examined in historical data?
Consequently, the various theoretical, methodological and empirical approaches in this volume offer a better understanding of the meaning of intra-individual variation for patterns of language development, language variation and change.
The inter- and transdisciplinary nature of the volume is an exciting new frontier, and the results of the studies in this book provide a wealth of new findings as well as challenges to some of the existing findings and assumptions regarding the nature of intra-individual variation.
