A quick note about the speed and some characteristics of mental change in adults, using an example from Ron Burnett. Accommodation can happen quickly when the right conditions are in place. Accommodation is the crown jewels of mental development, including many important forms of learning and knowledge building. It is what happens to your mind as it grasps a new concept, theory or set of concepts and can now see the world in a new way, in its terms. In Cognitive Productivity, I likened this to acquiring a new perceptual modality.
Most previous thinkers on the subject emphasized the purely “cognitive” aspects of accommodation. What strikes me however are the affective dimensions of many forms of accommodation. I.e., in accommodation one doesn’t simply perceive and think differently, but one’s value system changes. Information is now pertinent that didn’t use to be pertinent. Information gets internally connected in a valenced fashion in one’s mind/brain. One of my most important theoretical and practical concerns is to understand accommodation.
