In case you don’t have time to track it down right sway, the basic idea is that one stimulus triggers a response which changes the environment, creating a new stimulus… creating a pattern that feeds forward. To simplify a bit… One behavior feeds forward into another. A great example that my sister uses when teaching the theory is that she goes into the small restroom near her office daily, flips on the light and goes about her business. One day, someone had left the light on. She walked into the brightly lit room and flipped the switch, turning the light off. Her previous experience had set up a pattern, so the act of walking into that room fed forward to the act of flipping the switch — even if it made no sense.
R. Allen Gardner did the original work on the theory. That may help you track it down. If you can’t find it, let me know.
