Abstract

The thesis titled "A Consciousness Simulation Model" by R. Edward Mitchell (1977) explores the theoretical design of a digital model aimed at simulating human consciousness. The model is structured around a collection of independent processing modules that mimic various human cognitive and emotional processes. These modules include components for thought selection, ego/achievement, memory, and emotion processing, which interact with one another in a fashion that simulates aspects of human thought and behavior.

Mitchell's primary goal is to develop a system that could behave more like a human, particularly in communication and decision-making processes, to improve human-machine interaction. The thesis highlights that traditional computing systems, though powerful, remain "dumb" and are incapable of handling complex communication with humans due to a lack of what Mitchell calls "common sense" or "consciousness." His model aims to bridge this gap by simulating consciousness with a modular design that gives machines an illusion of human-like awareness and adaptability.

A critical feature of the proposed model is its focus on parallel processing, where multiple independent programs or "thought centers" analyze the same stimuli and generate responses based on their programmed behavior. These programs can "compete" or "collaborate" to produce a final system response, similar to how the human mind handles thoughts. The system also includes memory and emotional processors that influence the model’s overall behavior, offering human-like reactions such as joy, sadness, or curiosity.

While Mitchell's model acknowledges the limitations of contemporary computing power, it proposes methods for implementing basic artificial consciousness using existing technology. He suggests that such a model, though unable to fully replicate human consciousness, could be practical for use in industrial or business environments, providing more natural and effective human-computer interactions. The thesis serves as a forward-looking effort in the field of artificial intelligence and cybernetics, predating many modern advancements in AI technology.
