In two separate reports the founding and set up of Project CORES was outlined, and then a specific research project was described. Project CORES began in the efforts of three men who felt a more systematic investigation of simulation effects was needed. The criteria felt most sensitive were the physiological activities of galvanic skin potential and heart rate. A simulation chamber was constructed in the form of a small office with a screen where a program could be projected. The research project utilized the Project CORES facility with an added measure of concept meanings, the semantic differential technique. The concept meanings formed a pre- and posttest for a single group, N=32, going through the simulation sessions. A positive relationship between the degree of involvement as indicated by physiological activity and change in concept meaning was evidenced. (WH)
