Abstract :
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 experimental study was conducted on 29 male students in the climatic chamber under the
conditions of mild weather (40% relative humidity and dry bulb temperature of 20 °C) in the laboratory of the
School of Public Health, Isfahan, Iran in 2016. Participants took a rest for 10 to 15 min. Then they carried out
all tests of job skill assessment (BATTERY method) in 0, 40, 80, and 120 min after beginning. The number of
errors (accuracy assessment) and the duration of the test (pace assessment) were recorded. There was a
significant difference in the mean values of accuracy and pace in exposure to different intensities of lighting
(200, 500, 800, 1500 lux) while carrying out the job skill assessment tests (P<0.001). 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.
