Knowledge of PLANT was manipulated via different types of instructions, so that four different groups were created: (1) Minimal instructions only; (2) Minimal instructions + dynamic relationships (Principles); (3) Minimal instructions + guidelines for operation (Procedures); (4) Minimal instructions + Principles + Procedures + Relationships between Principles and Procedures. Subjects then controlled PLANT in a variety of situations which required maintaining production while also diagnosing familiar and unfamiliar failures. Despite the fact that these manipulations resulted in differences in subjects' knowledge as assessed via a written test at the end of the experiment, instructions had no effect upon achievement of the primary goal of production. However, those groups receiving Procedures controlled the system in a more stable manner. Principles had no apparent effect upon subjects' performance. There was no difference between groups in diagnosis of unfamiliar events.","Based on results of this and other research, the following recommendations are made: (1) Providing operators with operational heuristics and procedures can be an effective means of giving them an appropriate control strategy, and effort should be devoted to development of good procedures. (2) Knowledge of theoretical aspects of system functioning appears to have no impact upon control performance, and inclusion of theory in training programs should be judicious. (3) Training programs and operator evaluation should include both verbal content and experience with the actual or simulated process. (4) Attention should be devoted to providing operators assistance in using the knowledge they have.","Made available in DSpace on 2014-12-15T19:45:52Z (GMT).
