On second thought what you just described is intermittent reinforcement which can produce longer lasting training effects on animals that normal classical conditioning/reinforcement techniques. But lets not go there...however pertinent training may be to the original topic.

Is that really "intermittent reinforcement" (I'm assuming that's a valid name for it since you used it) or just confusing a dumb animal by throwing off it's perception of a simple pattern?
