Instead of adding two more to the pile of numbers in the set, the listener reduces the model to be "the odd numbers." Hearing that 5 and 9 are in the set added more than two small units information: It converted two medium-sized, competing models into a single, small model. The change in the size of the predictive model was relatively large. The "information received," being a measure of the momentary change in the receiver, is a transient quantity. Hearing the same sentence twice does not bring the same information the second time. Typically, the receiver's internal predictive model does not change as much, because the restructuring is usually smaller. Suppose the speaker repeats, "... 5 and 9 are in the set...” The listener already knows that 5 and 9 are in the set. At this point, the speaker can keep naming odd numbers without disturbing the predictive model of the listener ...» |
