| Abstract: | This research aims to investigate how task features within a video-based hazard prediction test affect item difficulty and the ability to discriminate between novice and experienced drivers. A video-based hazard prediction test was taken online by 77 participants. Along with the test, a small questionnaire and several demographic questions was administered to the participants. All scenarios within the hazard perception test were assessed based on several key task features, that lead up to a total task complexity score. The scored task features were related to performance on each scenario. Along with that, the degree to which each scenario was able to discriminate between experienced and novice drivers was also related to the task features of each scenario. The analysis showed no significant correlations between any of the task features and the performance on the test (test difficulty). A trend for the available time to think and the performance was found, this effect neared significance (r = 0.34, p = 0.06). The full test was unable to discriminate successfully between novice and experienced drivers. No significant differences were found for any of the scenarios in the intended direction. In scenarios 10 and 20, novice drivers significantly outperformed experienced drivers, directly contradicting the goal of the test. The correlational analysis between the discriminatory power of the scenarios and the task features resulted in no significant correlations. A strong significant correlation was however found between the discriminatory power and the difficulty of the test ( r = 0.59, p = 0.04). In conclusion, the study did not confirm a clear relationship between task features and either the discriminatory value or test difficulty. |
