Personality correlates and perceptual detectability of locomotive drivers

Abstract

In this study an attempt was made to determine the relationship of personality correlates with the vigilance performance of locomotive drivers in a continuous white noise background. Eighty locomotive drivers of Varanasi were selected, with a mean age of 35 yr. Each subject was instructed to detect critical signals which had slightly more height than the signals immediately after the presentation. The correct detection of tachistoscopic critical signals were recorded as the index of vigilance performance. Three personality scales viz. the occupational stress index (OSI), the job anxiety scale (JAS) and the 16 PF scale were administered after the completion of data regarding detection performance. Results were interpreted in terms of means, standard deviations and coefficients of correlation. A step wise multiple regression analysis was also done. The findings indicated that the personality correlates were significantly associated with sustained attention performances in different ways. © 1989.
