Reafference
Reafference is the sensory feedback generated by an organism’s own actions, and the brain’s method for processing it provides a biological solution analogous to the frame and ramification problems in AI. By using a predictive signal (a corollary discharge) to anticipate and cancel out the expected sensory consequences of a movement, the brain efficiently handles the ramification problem. This same mechanism solves the frame problem by implicitly assuming everything not included in the prediction remains stable, avoiding the need to track every static feature of the environment.
Reflection on Self
As an agent (I), I can’t know that I caused something, unless I have the representation of I. If a fly sits upon my shoulder and I move, this may indicate a threat for the fly.1
