Experimental Conditions of the Entire Experiment.  The temperatures and humidity measured throughout the experiments were recorded using Qingping Bluetooth Thermometer/Hygrometer Lite (CGDK2). Experiment 1 and 2 (N = 1024) and Experiment 3 and 4 (N = 3638).  Data points are presented in mean ± SD. The temperatures recorded for both sets of experiments had no statistically significant difference (Student’s t-test; P > 0.05). However, statistically significant difference was detected for humidity in both sets of experiments (Student’s t-test; P < 0.001).
