Perceptual control theory (PCT) is a psychological theory of animal and human behavior. PCT postulates that an organism's behavior is a means of controlling its perceptions. The model is based on the principles of negative feedback [1]. It is to some extent an application of the ideas used in the engineering discipline of control theory to the modeling of the human mind and behavior.

Controversy

It's unclear whether PCT is a valid theory that explains anything. The advocates of the theory on the blog were unable to make a clear case for it. For example, see these critical comments about the paper version of this technical report.

This blog post called out that PCT "has no theory of information or how that information comes to be made," and this post grappled with a similar problem: struggling to find a place for implicit models, priors, and updates when working with a PCT framework.
