On the complementarity of Chaos/Complexity Theory and Dynamic Systems Theory in understanding the second language acquisition process

In the late 1980s, I reviewed what was known about the field of second language acquisition (SLA), first with a co-author in a book (Larsen-Freeman and Long, 1991) and then in a highly condensed form for a 25th anniversary issue of the TESOL Quarterly (Larsen-Freeman, 1991). Stock-taking activities can be very useful, and I was grateful for these opportunities.
