A Theoretical Exploration of Mechanisms for Coding the Stimulus,
Abstract
The paper explores an information processing model of how stimuli are perceived and encoded. The model is an extension of recent work on human problem solving, which has yielded an explicit programming structure (a production system) as a representation of time course of human behavior in some relatively simple discrete symbolic tasks. The emphasis in the present paper is on obtaining an explicit representation of the control sturcture in the immediate processor and on the communication between the immediate processor and the perceptual system. The internal structure of the perceptual system is not explored in detail. The paper presents the original production system for problem solving and illustrates its structure and behavior. It then discusses the nature of stimulus encoding and what is provided by the model as it stands. This leads to the introduction of a task to guide the extension of the model. A model of the perceptual system is then presented and its behavior in conjunction with the main system illustrated. (Author)
