Title The perception of hazard - The contribution of signal detection to hazard perception.
Bibliographic information Nov. 1979, Vol.22, No.11, p.1177-1183. Illus. 5 ref.
Abstract The ability of workers to discriminate visually between dangerous and safe rock conditions in deep-level gold mines was examined. A training programme was developed in which stimuli were presented with the aid of stereoscopic slides to provide 3-dimensional views of loose rock and of surfaces on which there were no pieces of loose rock, and the responses analysed in terms of the theory of signal detection (McNicol). Underground experience and training significantly improves the ability of mine workers to discriminate between dangerous and safe rock.
