Abstract: To explore effects of safety signs on inhibition of attention return of high and low burnout miners, experiments were carried out on 2 groups of testees, a group of 20 miners at a high degree of burnout and a group of 20 miners at a low degree of burnout, by using safety signs without auxiliary words and those with auxiliary word as 2 different stimulating cues. IOR performances were analyzed for the miners in the 2 groups on the basis of both the reaction time and correct rate basis. The results show that under the 2 kinds of stimulation cues, for the 2 groups of testees, the IOR phenonmenon occurs in all time intervals, and there is no significant different between the 2 groups of testees in IOR amount when the auxiliary text cues are absent, and that when the auxiliary text cues exist, high burnout individuals' quantity of inhibition of return is significantly greater than that of the low burnout individuals, which means text clues can regulate the IOR.
