Description

The professional competency level of high-speed railway (HSR) dispatchers is key to the efficiency and safety of high-speed railway operations.This study employed standardized testing methods to collect test scores of high-speed railway dispatchers' professional competency levels, resulting in a regular curve of improvement in their professional competency levels.Through this regular curve, it was discovered that the improvement of professional competency levels has a time effect, with scores briefly rising at the beginning of the second phase before stabilizing, then stagnating, or even declining, indicating that improvement in professional competency levels is affected by the plateau effect.This study took 97 HSR dispatchers from Chengdu Railway Bureau as the research sample, using psychometric scales to measure personality traits, emotional regulation, goal orientation, and other personality system factors, as well as collecting demographic factors of the subjects.Correlation analysis and hierarchical regression analysis were used to explore the impact of personality system and demographic factors on professional competency level, as well as individual psychological susceptibility factors to the plateau effect.The results found that HSR dispatchers with a lack of experience, lower educational level, and performance-avoidance goal orientation might be more susceptible to the plateau effect.
