Picked this up from U101 tutor Clive Hilton's wonderful Creativity and Learning curation, all about switching off 'monitoring of your mistakes' when you want to get downright creative.
For the arty in the audience, it is possible to understand this insitnctively. We all sometimes just give up structured thinking and let our minds wander. What might be interesting here is that, just like jazz performance, this is something that can be practised and developed - anyone up for a bit of scatt creativity?
For the scienty, what's really interesting about this is that it seems to be an activation of Broca's region (not necessarily a reduction in activity in other areas, such as the pre-frontal cortex). Broca's region is traditionally thought to be fundamental to language cognition - both explicit and meta-linguistic. Could jazz really be a kind of body language (anyone up for a bit of Hip-Hop creativity Faceoff)?
