I thought that Prof. Gilbert's part about error correction and how our brains do error correction was really interesting. Of course, we form models and understandings of the world around us, but these models are very oftentimes wrong. Thus, we must reformulate our models to account for the things that we previously did not. However, as demonstrated by Prof. Goodman in the walking down sidewalk example, even correcting our models is not enough to stop us from failing sometimes. As she said, if we're already falling down, then we have made a correction that the sidewalk isn't very smooth, but it's too late now for the correction to the model to be made, and instead we have to be panic mode and hope that we catch ourselves from falling. Thus, our cognitive model of the world is constantly changing and being updated based on new information; however, this updating must be highly rapid in order for mishaps to be avoided (e.g., Prof. Goodman would've avoided falling if she had updated her model of the sidewalk soon enough to realize that it wasn't smooth).
