Study on the influence mechanism between ordinal factors and cognitive resource consumption

Abstract

Destination as the cognitive tasks have relatively fixed resource consumption, whether the ordinal factors influence the cognitive resource consumption or not is an important question, which means the threshold of dangerous performance may be anticipated accurately if the answer is found for true. Methods Two experiments are designed for cognitive analysis, which were based on the pilot-climbing status tasks. Each experiment procedure contains three steps of mode decision, warning and broadcasting. Orders were changed in two procedures. What’s more, warning task had two sub-steps, and climbing step had three sub-steps, the inside group orders were not changed while the steps transformed. The reaction time of each task, step and sub-step was checked and the implicit mechanism of the ordinal effect was drawn. Conclusions the sequence of the task implementation has a significant impact on the reaction time, which is a reflection of cognitive resources consumption. Although the repetition of tasks may cause the promotion of familiarity, the reaction time of the subsequent task is still longer than the previous one. The ordinal effect should be taken into account in the total amount of cognitive resources consumption and anticipation.
