At higher temperatures, women's performance on math and verbal tests is best, while men perform best on the same tests at lower temperatures, stated new study published in the open-access journal PLOS ONE by Tom Chang and Agne Kajackaite from the USC Marshall School of Business, Los Angeles, USA, and the WZB Berlin Social Science Center, Berlin, Germany.

Although many surveys have shown that women tend to prefer higher indoor temperatures than men, no experimental research examining temperature's effect on cognitive performance has taken possible gender differences into account. To address this gap, between September-December 2017, 24 groups of 23-25 students (542 participants total) took logic, math, and verbal tests in a room cooled or heated to one of a range of temperatures between 16.19 C/61.14 F and 32.57 C/90.63 F, receiving cash rewards based on the number of questions correctly answered. 41% of the participating students identified as female.

Conversely, male students generally performed better on these tests at lower temperatures - at the warmer end of the temperature distribution, they submitted fewer responses, as well as fewer correct responses. The improved performance of women in response to higher temperature was larger and more precisely estimated than the corresponding decrease in male performance. Temperature did not appear to impact performance on the logic test for either gender.
