Abstract:

The effects of subject aptitude and performance aid mode of presentation on the performance of procedural, between-stage troubleshooting tasks on a real piece of electronic equipment were studied. The study used nondecision aids presented in three modes, namely, an automatic retrieval of visual information, an automatic retrieval of audio information, and a manual retrieval of visual information. Two aptitude groups Air Force electronic index 40-60 and 75-95 with no previous electronic training or experience were given from 3 to 5 hours of task training before the experiment. Each subject solved 26 actual, and 11 synthetic problems. The study indicated no difference in effectiveness of aids using visual presentations. Both were superior to audio presentations. The two aptitude groups were equally effective in performing troubleshooting tasks using nondecision aids. In comparison with a previous study using decision aids, the study showed nondecision aids produced superior performance on the same between-stage troubleshooting problems using similar subjects.
