This study presents a formal device which can be used to display interlanguage variability while revealing its overall systematicity. Two types of variability are recognized: (1) production of a number of variant structures for a single target language structure at one point in time; and (2) variation over time that is attributable to the…

Discusses the similarities between the science of chaos/complexity and second language acquisition (SLA). Notes that chaos/complexity scientists focus on how disorder yields to order and on how complexity arises in nature. Points out that the study of dynamic, complex nonlinear systems is meaningful in SLA as well. (78 references) (Author/CK)
