Temperature and Low-Stakes Cognitive Performance
利用中国全国代表性纵向调查中八年的重复认知测试数据，研究发现测试日温度高于32°C会显著降低数学成绩，相当于减少0.23年教育，且对老年人和低教育者影响更大。
This study offers some of the first evidence in a developing country context that transitory exposure to high temperatures may disrupt low-stakes cognitive activities across a range of age cohorts. By matching eight years of repeated cognitive tests among all the participants in a nationally representative longitudinal survey in China with weather data according to the exact time and geographic location of their assessment, we show that exposure to a temperature above 32°C on the test date, relative to a moderate day within 22°C–24°C, leads to a sizable decline in their math scores by 0.066 standard deviations (equivalent to 0.23 years of education). Further, the effect on the math test scores is more salient for individuals who are older or less educated.
