Everyone knows that perception is the result of a combination of pickup (bottom-up processing) and expectation (top-down processing). There are many, many ways to implement this idea.
Richard, Thanks for describing perception, in the same fashion that I believe is explained by James Albus in his design for intelligent systems. I'm adopting that for Texai. For example, in discourse, a received utterance is perceived and comprehended in a context that is rich with expectations drawn from the previous utterances and the common ground (shared knowledge) of the participants. -Steve Stephen L.

This is the issue of top-down vs bottom-up processing. Everyone knows that perception is the result of a combination of pickup (bottom-up processing) and expectation (top-down processing).
