The Journal of Mind and Behavior , Spring 1989, Vol. A distinction is drawn between a predicational and a mediational model in accounting for human cognition.
Predication is a process moving from a wider to a narrower context of meaning.
The wider context of meaning is intrinsically oppositional. Mediation involves taking in or inputting factors which are not initially a part of the process but which come to play a directing role in that process. It is the frequency and contiguity of such inputs that direct the mediational process. The aim here is to confront the mediational theorizing of network theory with the predicational theorizing of logical learning theory. It is predicted that the direction of impression formation can be stipulated based upon oppositionality even though frequency and contiguity are removed from consideration.
