Effects of manipulation of augmented knowledge of results and work surface angle on performance of a serial positioning task.
The effects of manipulating augmented information feedback on performance efficiency of 24 male adults in a simple motor skill were studied. The three levels of information feedback were no augmented knowledge of results, positive augmented knowledge of results and negative augmented knowledge of results, using light and tone as signal modes. The motor skill was a serial-positioning movement, simulating many industrial assembly tasks, and was given at three work surface angles (0 degrees, 9 degrees and 18 degrees), utilizing an automated geometric work station. Results indicated that, disregarding the signal mode, feedback had no effect on performance. However, when light was utilized as a mode of signal, results were superior at 0 degrees and 18 degrees angles when positive knowledge of results was provided. Work surface angle had little effect on performance efficiency, the 18 degrees angle being slightly superior to the 0 degrees and 9 degrees angles.
