بررسی اثرات توام گرما و روشنایی بر روی زمان واکنش دانشجویان در شرایط آزمایشگاهی

Introduction: In many workplaces there is exposure to heat and light simultaneously. This study investigated the combined effect of heat and lighting on some cognitive performance, i.e. reaction time. Methodology: the present semi-experimental study was conducted 2015 on 33 healthy students (16 girls and 17 boys) with a mean age of 22.1 in the thermal stress chamber. The reaction time parameter by the reaction time measurement device, after exposure to different heat surfaces (dry temperatures 22 &deg;C and 37 &deg;C) and lighting surfaces (200, 500 and 1500 lux). Data were analyzed using ANOVA test in SPSS-20. Results: The results showed that the average simple, diagnostic, two-color selective, two-sound selective reaction times and reaction time error increased after combined exposure to heat and lighting and showed a significant difference (P<0.05). The maximum score of reaction time belong to temperature of 37 c&deg; and lighting of 1500 lux, the minimum score of reaction time belong to temperature of 22 &deg;c and lighting of 1500 lux.
