That is a great question, and thinking about it a bit, I am wondering how quickly one becomes aware of this.
Taking this a bit further, in the Jack Mezirow perspective, which is primarily cognitive, there would seem to be a rather suddenness of this, so it the learning would not occur until the transformation already occurs. However, in teh Meyer and Land perspective of threshold concepts and troublesome knowledge, there is less a focus on the cognitive element.
Hmmm, I wonder if perhaps there may be another direction for my research . . .
Thanks for asking this question, Cristina.
