Sažetak:
The findings on selective attention (SA) aging decline, although depending on the specific SA test, have significant implications for the population of professional drivers, in particular given their role in traffic safety. For this reason, we found it vital to examine the effects of aging on SA in railroad engineers and its’ relation to different measures of SA interference. A study was conducted by using 2 forms of the Stroop test: the 1st - verbal uncoloured and the 2nd - verbal coloured paper-and-pencil form. Both forms consisted of two parts: with incongruent stimuli (measured SA and processing speed, i.e. PS) and with neutral stimuli (measured PS). The subjects were male drivers of the Croatian Railways, ages 25-59, non-evenly distributed into 4 age groups distinguished by specific functional characteristics of professional drivers. 50 subjects completed the 1st and 52 completed the 2nd form. The subjects’ task was to cross out as many of the target words in the context of distractors during 60 seconds (with distraction more intensive at incongruent stimuli). Descriptive statistics for both forms of the SA interference (SA time – PS time) indicates expected mean scores, with normal distributions. The interference variability across age groups was homogenous at the 1st Stroop form, but not at the 2nd one. The mean number of errors in the 1st Stroop form is as expected, very low with positive asymmetric distributions and homogenous variability, while in the 2nd one, errors are evident only for the 30-39 age group. For the 1st Stroop form, a significant difference in SA interference time was found between the 40-49 and 50-59 age groups, the latter showing a higher interference. For the 2nd Stroop form, no significant effects of age on SA interference were found. The effect of specific experience of railroad engineers with colours (red-green) is indicated by the results. The findings are discussed in relation to the theory of cognitive aging and empirical findings in the general population, with the implications on railroad engineers aging process.
