ABSTRACT

Tasks and methods can be considered mediating concepts in problem solving (Chandrasekaran, Johnson and Smith 1992). The symbolic and connectionist methods because of their different philosophical, cognitive and computational underpinnings impose their own constraints on the quality (e.g. time, resources, user intelligibility, no. of levels of abstraction/solution hierarchy, reliability, etc.) of task accomplishment. Further these constraints can lead to task generation depending upon which constraints have been violated by a certain method, and the degree of tolerance of the violated constraints. A proper integration of symbolic and connectionist methods for task accomplishment can thus improve the quality of task accomplishment and restrict task generation. Besides such an integration has important implications in terms of overall understanding of the human information processing system. A proper integration of the symbolic and connectionist methods can be achieved by explicitly outlining integration at the task structure level, computational level, and the program level (see Figure 1).
