Problem Solving Under Time-Constraints.
Richardson, Michael; Hunt, Earl
A model of how automated and controlled processing can be mixed in computer simulations of problem solving is proposed. It is based on previous work by Hunt and Lansman (1983), who developed a model of problem solving that could reproduce the data obtained with several attention and performance paradigms, extending production-system notation to time-constrained problem solving. Four college students were required to do mental arithmetic rapidly, keeping track of the running total of a visually presented series of numbers using base three (to keep the task from being fully automated). From time to time, they had to deal with an interruption and then return to the arithmetic task. The students generally, but not always, managed to remember the things they needed to remember, and often became aware of an error after making it, indicating there was a good deal of self-monitoring of behavior. The problem solver's internal control of information seems to be an essential part of real-time problem solving. These processes were reflected in the simulation model, which is described in detail.
