Towards a Complete Model
In this chapter we compare and contrast our two models, first with each other and then with data from biological experiments. Our analysis suggests that frogs and toads do not use a single means for determining depth but, instead, use two different processes, one for determining depth of stationary environmental objects and the other for determining depth of prey. We present an accommodation control system that meets the needs of both of these processes, and show how some of the discrepancies between animal experiments and our prey localization model would be eliminated by the nonlinearities inherent in this control. The chapter concludes with an evaluation of the depth scale used in the two models.
