The current document is an edited and reduced version of an earlier report. In the current document, an attempt hasbeen made to improve readability through a reorganisation of the material and the elimination of content that is not central to understanding the function of the IP/PCT model within IPME. The essence of the IP model is that all factors that impact on humancognitive workload can be reduced to their effects on the amount of information to beprocessed and the amount of time available before the decision has to be actioned. Fromthis position, it can be shown that if humans are limited at the rate at which they processinformation then operator workload, performance, and error production are all functions ofthe time pressure. The IP Model is about time and the information to be processed.The PCT Model argues that humans behave as multi−layered closed loop controlsystems. The set points for these control loops are our perceptual goals (or how we wantto see, hear, feel, taste, or smell the state of the world). According to PCT, we sense theworld state, forming a perception of that state which we then compare with our goal. Ifthere is a difference between our perceived and desired states, we formulate an action.This action is implemented in order to operate on the world so as to drive the perceivedstate of the variables of interest towards the goal. The perceptual processes and thedecisional processes draw on internal knowledge states that transform sensation toperception, and difference to action. Our attentional mechanism shifts our focus from loopto loop to loop. The PCT model is therefore about Goals, Attention, Knowledge andFeedback. |
