As the less resistant fields are destroyed while the more resistant remain, the average movement of the repre- sentative point, as the parameter is alternated between p' and p", will change from a large circuit like C towards a small central circuit like D. So both the number of step-function changes and the range of movement evoked by the stimulus p will diminish. Habituation 13/10. Some uniformity is now discernible in the responses of an ultrastable system to repeated stimuli. There is a tendency for the response, whether measured by the number of step-functions changing or by the range of movement of the main variables, to diminish. The diminution is not due to any triviality of definition or to any peculiarity of the homeostat: it follows from the basic fact, inseparable from any delicate or ultrastable system, that large responses tend, if there is feedback, to destroy the 151.
