Summary

This study investigates the validity of the Traffic Monotonous Attention Test (TMAT) as a measure for psychotechnical driver assessments in Turkey, where recent laws mandate such testing for drivers with serious offenses. Motivated by high traffic accident rates and the need to identify drivers with suitable cognitive abilities, the researchers examined the relationship between monotonous attention and driving behaviors, including violations, errors, and accident involvement. The study specifically hypothesized that low monotonous attention would correlate with higher accident rates and that drivers involved in active accidents (where they hit another object) would exhibit lower attention levels than those in passive accidents. The methodology involved 79 volunteer drivers from Ankara, Turkey, comprising automobile and taxi drivers. Participants completed the Driver Behavior Questionnaire (DBQ) to self-report violations and errors, along with demographic data regarding their accident history over the previous three years. They also performed the TMAT, a paper-and-pencil cancellation task requiring the identification of 75 target traffic signs within a matrix. Performance was measured by correct, incorrect, and omitted responses, with an attention index calculated as the ratio of incorrect to correct responses. Statistical analyses included correlation tests and ANOVAs, with participants categorized into high, medium, and low attention groups, as well as groups based on accident type (no accident, active, passive). The results revealed that initial correlations between the attention index and major variables were largely non-significant, suggesting a nonlinear relationship. ANOVA results indicated that drivers with medium levels of monotonous attention reported significantly higher levels of driving errors than both high and low attention groups. Regarding accident involvement, drivers who experienced active accidents had significantly higher rates of both incorrect and omitted responses on the TMAT compared to drivers with no accidents or passive accidents. No significant differences were found between the no-accident and passive-accident groups. The findings imply that individual differences in monotonous attention are specifically related to the risk of active accidents rather than general accident involvement. The study suggests that drivers with intermediate attention levels may suffer from "illusory over-confidence," leading to higher error rates, while those with low attention may drive more cautiously. Consequently, the authors conclude that monotonous attention measures should be included in computer-based psychotechnical assessment systems, particularly for screening drivers prone to active accidents. The study acknowledges limitations regarding the paper-and-pencil format and mixed sample, recommending future research using computerized testing.
