I love the definition of "Creativity" being about puzzle-creating and puzzle-solving. See previous blog post. Maybe it's because I love playing board games, and I love creating illustrations that feel useful. (note that "decorative superficial stuff" can also be useful to someone)
I jotted down these notes from Barbara Heidenreich's video on Teaching Animals "Creativity" . The takeaway message for me is that Creativity is not "insight" in a magical sense (like it just suddenly happens because the individual is a genius) but that when view through a Behaviorist lens, there are learning processes at work like Extinction and Resurgence.
