Temperature and High-Stakes Cognitive Performance

This study provides the first nation-wide estimates on temperature effects on high-stakes cognitive performance in a developing country using data from the National College Entrance Examination (NCEE) in China. The NCEE is one of the most important institutions in China and affects hundreds of millions of families.

A one-standard-deviation increase in temperature (3.29° C) decreases the total test score by 1.12% (9.62% of a standard deviation) and decreases the probability of getting into first-tier universities by 1.97% (4.38% of a standard deviation).

This suggests that temperature plays an important role in high-stakes cognitive performance and has potentially far-reaching impacts for the careers and lifetime earnings of students.
