The six experiments presented in these two manuals were designed for use in any introductory or advanced undergraduate psychology course either partially or totally concerned with human cognition. One manual serves as the teacher's accompaniment to the actual experiments detailed in the student's manual. A list of textbooks which might be compatible with the manual is provided in the instructor's section and shows the chapters from each book relevant to each experiment. The approach of the manual is unique in that it requires the active participation of the learner. Each of the six experiments is run on a timesharing computer system using a teletype terminal as the input/output device. The computer presents a task to the student and to a model or miniature theory which is supposed to describe the student's thinking in the task. The student is then asked to compare his performance with that of the model, and to compare what he thought he did in the task with what the model said he did. The experiments cover the range of cognitive activity represented in the current general conception of the human information processing system. (Author/PC)
