Language destabilization and (re-)learning from a Complexity Theory perspective
Timescales and patterns across four studies
Conny Opitz | Trinity College Dublin & University of St Andrews
The growing interest in Complexity Theory (CT) within second language acquisition has refocused our attention on development and change, as exemplified by the non-linear processes of language destabilization and (re-)learning in multilingual systems. It is clear that this theoretical perspective has important implications for empirical research from design to analysis and interpretation. In this chapter, I take a first step towards applying the theoretical apparatus of CT to findings obtained in four different studies of multilingual development. I show how the findings can be interpreted using CT as a post-hoc theoretical prism and, in turn, how the findings support and explicate CT claims. The four studies involved multilingual adult second-language learners and users in Ireland and were designed to address different timescales ranging from weeks to years, and time windows from one year to decades. Thus, the study goes some way towards de Bot’s (2012, 2015) suggestion to investigate complex dynamic systems by focusing on adjacent timescales. Although the studies differ in their purpose and design, they partially overlap in methodology and analysis, and exemplify how, through convergence of methodological and analytical procedures, one may generalise from the particular.
