Behavioural studies were conducted on a random sample of 38 glass bangle workers engaged in various occupations and exposed to high ambient temperature (38.2 +/- 3.4 degrees C) and radiant heat (46.2 +/- 5.1 degrees C) during their work in the glass bangle industries at Firozabad, India. Twenty-two control subjects of similar age and socio-economic status unexposed to heat during their work were also studied for comparison. The digit span test, digit symbol test, Bourdon-Wiersma vigilance test, flicker fusion test and Maudsley personality inventory (MPI) were used to assess the behavioural changes induced by the existing heat stress. The mean scores of immediate memory were much lower in the exposed population than in the controls thereby indicating impairment of immediate memory in the study group. The visuo-motor coordination and vigilance were also significantly affected. Visual perception showed a downward trend among the glass bangle workers, although the MPI test indicated no personality changes.
对印度菲罗扎巴德玻璃手镯行业中随机抽取的38名从事各种职业且在工作期间暴露于高温环境（38.2±3.4摄氏度）和辐射热（46.2±5.1摄氏度）的玻璃手镯工人进行了行为研究。还对22名年龄和社会经济地位相似且在工作期间未接触热的对照对象进行了研究以作比较。使用数字广度测试、数字符号测试、布尔东-维尔斯马警觉性测试、闪烁融合测试和莫兹利人格量表（MPI）来评估现有热应激引起的行为变化。暴露人群的即时记忆平均得分远低于对照组，从而表明研究组的即时记忆受损。视觉运动协调和警觉性也受到显著影响。尽管MPI测试表明人格没有变化，但玻璃手镯工人的视觉感知呈下降趋势。
