Operator’s Human Error Features in Compensatory Tracking Task Based on Cognitive Process

To explore the cognitive characteristics of human error in different cognitive processes and the correlations between basic cognitive abilities and compensation tracking task, a simulated compensatory tracking task with four stages (perception task, judgment task, regulation task and comprehensive task, in which the comprehensive task include perception link, judgment link and regulation link) was performed. Four basic cognitive ability of 36 volunteers and the performance of the compensatory tracking task were obtained for statistical analysis. The results showed that the error rate of perception task/link was the lowest and that of regulation task/link was the highest. Moreover, the sustained attention ability was significantly associated with perception and regulation task. The working memory ability was significantly related to perception task. These observations indicated that human errors are most likely to occur in the regulation phase, and sustained attention and working memory are important abilities in compensatory tracking task.
