[The influence of computer work on reaction time and accuracy in VDT operators].
The study of simple reaction to light and sound, and differential reaction was carried out on the group of VDT operators (n = 62) and the group of persons not involved in VDT operation (n = 38). Concentration ability was tested with Couve's test twice a day, i.e. before and after work. In the analysis of the results, reaction time and the accuracy of psychomotor trials measured by the number of errors committed were considered. None of the research models disclosed statistically significant differences between the average figures calculated for the VDT operators and the other group. The figures registered before and after work in each group were not significant either. Both group also failed to show the influence of age on the duration of reaction. The ability to concentrate was lower among operators than among those not involved in VDT operation, and it decreased after work, especially in the oldest subgroup.
