Perceptual control theory in a nutshell

Are you familiar with perceptual control theory? If you aren’t, the basic idea is this: People are not rocks. As Philip Runkel puts it,
“Living creatures behave very differently from lifeless things. Unlike a rock, a human does not just sit until something bumps it.”
– Philip Runkel, “Casting Nets and Testing Specimens,” pg 75

The idea is, organisms and agents and people get a bunch of different sensory inputs. They have some internal standards for what they want that set of sensory inputs to be like — some desired state of the world. The difference between how they want the world to be and what the world is actually like drives what they do — what we see as behavior.
The reason this is appealing to me? Perceptual control theory (PCT) says we’re not just input-output machines. Behavior is goal-directed and purposeful.
It’s a useful theory if you want to figure out why people are doing what they do and how to avoid or mediate conflict. Everyone has internal standards that they’re trying to control. As Runkel says,
“[M]ost of us very often act as if we expect other people to behave like rocks. And when we act toward other people as if they were rocks or blankets or typewriters or teacups, we make unending trouble for ourselves. It is true that people do have some features in common with rocks and typewriters. There are, however, important differences between living and nonliving things that most of us overlook time and time again, and to our sorrow.”
– Philip Runkel, “People as Living Things; The Psychology of Perceptual Control,” pg 14
If you want to learn more, I’ve found you a nice list of articles, an informative Less Wrong post a friend linked me to, a comprehensive website, and Google.
And yes, talking about PCT really just was my excuse to share those lovely quotes from Runkel.
My lab is lined up in the front row, fidgeting, exchanging nervous glances. We trade seats between the other students’ presentations, taking turns with the laptop to read over the half-done powerpoint.
He kept repeating that: don’t worry. It’s just a presentation.
One of the difficult parts of playing a new sport is that I’m not good at it yet.
My usual sport is fencing: highly individual, always solo. When you’re on the strip, it’s just you. If you mess up, if you lose, you only have yourself to blame. Even in team competitions, you’re just adding up the scores you and your teammates have separately acquired. You don’t realize, unless you’ve been part of a team, how important it is to trust your teammates. And that’s what made volleyball difficult: because none of us were that good, it wasn’t easy to trust my teammates to be there, backing me up, putting in their best effort to win even though the games were casual and couldn’t be taken seriously given our level of experience.
