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.
