Psychometric assessment tools aimed at measuring the driver’s ability to maintain focus and sustained attention while driving, as well as their resilience to external or internal distractions. These tests are based on scales such as the Continuous Performance Test (CPT), which assesses the ability to respond accurately and consistently to targeted stimuli, ignoring irrelevant or distracting stimuli, providing quantitative measures of attention levels, concentration, and potential distractions. This type of test focuses on the level of sustained attention, processing speed, the ability to constantly monitor traffic conditions, and the ability to distinguish between important and irrelevant information. It also measures the driver’s ability to maintain attention for long periods of time, which is a critical factor for safe driving, especially on long journeys or on busy roads where there is an increased risk of mistakes as a result of distraction or loss of concentration. The practical application of these tests is to assess the driver’s ability to control the road and predict potential hazards, helping to identify drivers who may be more prone to crashes due to lack of attention or a tendency to leave the lane. The results of these tests are also used to develop training programs aimed at developing concentration, driver assistance systems that reduce the likelihood of driver errors, as well as in traffic studies to study the relationship between attention, distraction and driving quality, contributing to improved road safety and the development of more effective preventive strategies.
