The analysis of the impact of lighting on accuracy and pace of working in men by tests of job skill assessment under experimental condition

the results of the studies indicate that harmful physical factors of workplace including lighting may affect the cognitive performance of human. Therefore, tests of job skill assessment (BATTERY method) were used to conduct this study under experimental condition, with the aim of determining the effect of lighting on the accuracy and pace of working in men.
this interventional study was conducted on 29 male students in the environmental chamber of School of Public Health, Isfahan University of Medical Sciences, under the conditions of mild weather (40% relative humidity and dry bulb temperature of 20 ° C). After gathering demographic information, participants took a rest for 10 to 15 minutes. Then in 0, 40, 80, and 120 minutes after beginning, they carried out all tests of job skill assessment (BATTERY method) including clockwise and counter-clockwise two-arm coordination test, V Pieron test, and vibrometer test of targeting accuracy measurement. The number of errors (accuracy assessment) and the duration of the test (pace assessment) were recorded by the researcher.
the one-way analysis of variance (ANOVA) with repeated observations, indicated that there was a meaningful difference in the mean values of accuracy and pace in exposure to different intensities of lighting while carrying out job skill assessment tests (P the results of the present study indicate that an increase in the intensity of lighting may enhance people’s performance and limit unsafe behaviors by increasing the accuracy and pace of working while conducting cognitive activities.
