Based on attitude questionnaires and film analysis. three training simulators, electromechanical (E), perceptual (P), and (E) + (P),were developed to teach suturing to medical students. Training effectiveness on these simulators was compared to the traditional training method. Intergroup comparisons were obtained by having nine subjects from each of the three experimental groups, subsequent to training, practice on porcine skin by placing 35 sutures similar to those o{ the traditional group (N = 9). Results indicate that all three experimental training methods provided for significantly better quality of performance, briefer training times. and less psychophysiological stress (as measured by sinus arrhythmia, chin and neck EMG, and skin conductance) than the traditional training method.
