- Abstract:
- In order to study the factors that influencing the speed judgment after finishing a secondary task，and to study how the difficulty of the secondary task and respond clue interval influences the switching cost, a typical experiment scenario based on EPrime was developed. In the experiment, the driving speed judgment task was selected as the main task, and a typical alternative driving distraction task (arrow direction selection task) was selected as the secondary task. Eightyseven participants participated in this experiment and made judgments according to the quality. For the experiment, secondary task complexity and task interval were considered as two independent variables, and each variable had two experimental levels. There were four groups of experiments, and each group included two situations, doing two adjacent main tasks and switching to the main task after finishing the secondary task. The results show that the drivers reponse time for the main task is more after switching from the secondary task to the main task, compared to performing two adjacent main tasks, and there are significant differences (p<0.01). The drivers reponse time for the primary task increased when the secondary task became complex, and there are significant differences (p<0.001). When the task interval changed from 200 ms to 2 000 ms, there is no significant effect on the average reponse time for the primary task. There is no significant interaction between the two factors. It still has an influence on the main task after finishing the secondary task. Besides these factors, gender and age also have an impact on the reponse time. The conclusions of this study can provide a reference for the optimal design of invehicle information systems. 5 tabs, 7 figs, 30 refs.
