THE EFFECT OF AMBIENT AND BODY TEMPERATURES UPON REACTION TIME

Studies of reaction time are reported for temperatures from -50 degrees to 117 degrees F. The following conclusions apply to simple discrimination and to choice reaction times within the range of conditions examined. The conclusions should not be applied to speed of other performances. a Reaction time does not vary significantly with low ambient temperatures provided the body generally and the responding member in particular are properly protected. b During exposures for several days to temperatures as low as -20 degrees F, clothing can adequately protect the body without interfering significantly with the speed of the simple reaction. c For periods of about an hour, current-type clothing affords adequate protection against ambient temperatures as low as -50 degrees F. d Conditions which may reduce strength and dexterity of movement may leave reaction time unchanged. e Reaction time does not vary significantly with high ambient temperatures up to 117 degrees F provided the wet bulb temperature does not exceed about 86 degrees F.
