This is a bit of a theoretical question I guess but as you have lots of experience hopefully you'll be able to help me out.
Obviously teachers want to get their students to produce more complex, longer stretches of talk and so getting them to recount events which have an emotional resonance is one way of doing this. I've attended training sessions with titles like 'Speaking From Within' which this kind of approach .
However, I'm sure I also remember hearing research cited which suggested that when we start to talk about an emotional topic, we are actually less likely to remember to be accurate and any new vocab as we're too focused on the content of what we're saying. Any ideas specifically where I might have got this from?
As I said, I know this is a bit theoretical but hopefully others will find the subject of 'emotional classroom talk' interesting and useful.
