The Automatic Language Growth page on this site features the script of the video and will eventually include and link to more detailed background information and research. For now you can watch the video and read this synopsis:
Almost everything I write here will directly reference or be influenced in some way by my knowledge and experience of Automatic Language Growth, so it’s worth starting off with a summary of this approach to language learning.
Automatic Language Growth, or ALG, is intended to bring learners of any age from no knowledge of a language to the native speaker’s level of ability without conscious effort.
ALG is based on the theory that, contrary to popular belief, adults have not lost the ability to pick up languages as effortlessly as young children do, and reach native-like levels of fluency and accuracy.
What has actually changed is their environment and the approach that they take, and these changes are the cause of the difficulties and lower attainment we typically observe in adults.
