Psychomotor Responses and Their Relationship to Personality Traits of Young Men Performing in High Ambient Temperature (110 F)

The purpose of this study was to isolate relationships between psychomotor responses and personality structure. Fifteen subjecs were administered the Thurstone Temperament Schedule. Stress was provided by a heat chamber with an ambient temperature of 110 F (30–50 percent R.H.) and walking on a treadmill which moved at 4 mph at zero grade. Analysis of the data permits the following conclusions: (a) two-hand coordination showed a positive significant relationship to the measure of competitiveness; (b) tapping showed a positive significant relationship to the vigorous and sociable traits; and (c) a significant positive relationship between strength and the active trait was found. Hand and arm steadiness had a significant negative relationship with the emotional stability trait.
