So what is this escape hatch that you've written about?

The way I would describe it is sort of like the fact that the brain, the body, and the environment are extremely tightly integrated, means that if you sort of wiggle anywhere in that system, it's going to show up.

It's going to have an effect all across the system.

And so as a concrete example, in my lab, I did a study looking at mental rotation.

And I wanted to manipulate the non-neural body, so I did that by restricting hand movement, even though hands were not, strictly speaking, involved in this task.

It was a mental rotation task.

And restricting the hand movements had an effect on the ability to mentally rotate.

I just don't have an answer.
