A sometime enthusiast of the Automatic Language Growth approach recently remarked to me that there’s a somewhat cultish aspect to the theory.
I definitely agree that the central claims of ALG—that given the right experiences and approach, adults can acquire new languages effortlessly and approach native-like levels of fluency—are of the sort that can inspire potentially cult-like devotion.
One of the main messages I try to communicate is that there are good reasons to take such claims seriously and they need to be the subject of rigorous scientific research.
In the meantime, we need to think clearly and carefully about how we go about putting ALG ideas and concepts into practice.
A danger that can arise from an uncritical devotion to ALG based on aspects of the theory that can capture the imagination is to become dogmatic about applying it without regard to practical concerns such as the overall context.
