given goal state. The model is referred to as connectionistic rather than neural, be­ cause, while the basic components are neuron-like, there is only limited commitment to physiological realism. Consequently the neuron-like ele­ ments are referred to as "nodes" rather than "neurons". The model is directed more at the behavioral level, and at that level, numerous con­ cepts from animal learning theory are directly applicable to connectionis­ tic modeling. An attempt to actually implement these behavioral theories in a computer simulation can be quite informative, as most are only partially specified, and the gaps may be apparent only when actual­ ly building a functioning system. In addition, a computer implementa­ tion provides an improved capability to explore the strengths and limita­ tions of the different approaches as well as their various interactions.
