Mr. Hen, I'm going to break custom and say something that may be regarded as poisoning the well. It's my conclusion that P.J. Eby is more or less a quack trying to drum up support for his psychological services, and that (in such an important matter as this) you shouldn't be trying to understand his jargon, let alone trying to take his advice.

His persistent trumpeting of perceptual control theory, which couples grandiose claims of precision with a complete lack of experimental support, is telling, and it's not the only red flag I've seen...
