I would say computation provides models for these systems, but, in general, these systems are not themselves computations - some of them are not literally the manipulation of abstract symbols by formal rules. But, from a broader perspective, I don't think the "is this computation" question is a very useful one to pursue. Any true understanding of the conscious mind will have to answer the question of why it is different from the things we understand now: if it is, in fact, computation, then it is different in some way from the computations that we do understand now, and it is the differences that will be key to understanding it. When we understand it, we will have a informed basis for fitting it into our ontology.
