Studies on the learning effects of target-aiming performance (author's transl)

Abstract

The TAF (Target-Aiming Function) -test applicable to the evaluation of industrial fatigue is one of the performance test, which is due to a feed back system composed of vision, cerebral cortex and action. The present study was performed to clarlify the learning effect in TAF. A standardized curve of the TAF-tests was obtained from eleven healthy male students, being tested 5 times a day in the morning from Monday to Friday. The effects of frequency and duration of trainings on the performance curve TAF-L (L indicates the average level of TAF) were observed. The results obtained were as follows.1) The significance of daily, weekly and individual changes of TAF-L and TAF-D (D indicates the, standard deviation from L) was confirmed by variance analysis. The significant interaction in TAF-L between daily and weekly change, weekly and individual change, in TAF-D, weekly and individual change were recognized respectively.2) When the TAF-tests were employed for the study on the diurnal working load, subjects should be trained at least 5 to 7 times a day before starting the experiments in order to obtain reliable data.3) When the TAF-tests were employed for the analytical study on comparatively long duration as weekly or monthly working loads, subjects should be trained 5 to 7 times a day for 3 days. 4) Control value of TAF-L at the resting time showed about 1.0. This value may be considered to be a critical point of TAF-L, therefore the values obtained above this value would be attributed to the lack of trainings.
