mini lightbulb moment

...and a mini entry. I'll write something more substantial soon, honest! I was just talking with a colleague about how you end up not noticing half the things you do in your job once you've been doing the same thing for ages. You know what it's like - you automatically fill in forms, give enrolments, write up stuff, and virtually forget that you've done it at all.
It suddenly struck me that this is precisely what happens in acculturation and fossilization in adults in an L2 environment. It is not merely that they are 'stuck' in their language learning: rather, they have acculturized and fossilized to their entire lifestyle. This would explain why adult learners tend not to progress with language learning - they've simply got used to doing the same old things in the same old way, just because the same old things in the same old way work well enough for them in the way of life they've got used to!
So, what approach could we take to rouse them from their slumbersome routines? Something like a Buddhist bell might work - a sudden 'chime' to bring somoeone back to mindfulness.
Personally, I favour cattle prods.
More on this later.
