Tetris

In this ongoing series of studies, the CogWorks lab is interested in studying the distinction between "epistemic" and "pragmatic" actions. Pragmatic actions are quite straightforward, but the idea of an epistemic action is that when a mental computation is estimated to be too taxing, we can sometimes "offload" the thinking into the world by manipulating it a certain way. Tetris provides us with a fantastic testbed to evaluate the role these actions have in learning. In this video, the frame changes color when we suspect an epistemic action is underway.
