Subjective comfort vote and air temperature as predictors of performance in factory workers.
Volunteer factory workers performed a series of tests in a mobile climate laboratory. The tests simulated factory skills and were performed at 6 degrees, 12 degrees, 18 degrees or 24 degrees C at low vapour pressures. At each temperature four groups of about 30 workers were tested: black men, and women and white men and women. A first order polynomial was used to fit the data for temperature and comfort vote. The comfort vote predicted about 6% of performance, temperature about 11%. On some manual tasks air temperature predicted more than 40% of performance. There were few differences between the groups.

Finger skin temperature and manual dexterity - some inter-group differences.
The relationship between finger skin temperature (FST) and performance was demonstrated with four manual dexterity tasks all of which were performed by black and white, male and female subjects. At air temperatures below 24 degrees C the white subjects tended to have warmer FSTs than the black subjects; white subjects were also able to equal the performance of the black subjects at air temperatures as much as 6 degrees C below that required by the black subjects.
