Abstract:

Time-to-contact (TTC) estimation refers to predicting the time for a moving object to reach a specific position. Using an occlusion paradigm, the present study conducted two behavioral experiments to investigate the effects of attentional load on TTC estimation under different time structure conditions. Experiment 1 found that when time structures were consistent, there was no significant difference in performance between high and low attentional load conditions. When time structures were inconsistent, performance under high attentional load was significantly higher than under low attentional load. Experiment 2 distinguished between consistent time structure information and consistent distance structure information. Results showed that attentional load had no significant effect on TTC estimation when time structure information was consistent, whereas high attentional load improved task performance when distance structure information was consistent. In summary, this study suggests that attentional load only affects task estimation under inconsistent time structure conditions, but not under consistent time structure conditions.

摘要：

碰撞时间(time-to-contact, TTC)估计是指预测运动客体到达特定位置的时间。目前尚不清楚注意分配在TTC估计中的作用机制。本研究利用遮挡范式，通过两个行为实验，探讨了注意负荷对不同时间结构条件下TTC估计的影响。实验1发现，当时间结构一致时，被试在高低注意负荷条件下的绩效无显著差异；当时间结构不一致时，被试在高注意负荷条件下的绩效显著高于低注意负荷条件。实验2在区分时间结构信息一致和距离结构信息一致后，结果显示当时间结构信息一致时，注意负荷对TTC估计无显著影响，而当距离结构信息一致时，高注意负荷提高了任务绩效。综上，研究结果提示注意负荷只影响时间结构不一致条件下个体的任务估计，而不影响时间结构一致时个体的任务估计。
