| 摘 要： | 本研究旨在探讨运动信息对多目标追踪的影响, 具体为考察多目标追踪中是否存在基于运动信息的分组效应, 以及不同类型表面特征(颜色和形状)对这一效应的影响。实验1发现多目标追踪中存在基于运动信息的分组效应, 并且这一分组效应是自动化的。实验2和实验3分别在不同颜色和不同形状组合条件下考察了基于运动信息的分组效应的稳定性, 结果都表明不同表面特征的组合不会干扰基于运动信息的分组效应的形成, 但其效应量都因表面特征的出现而缩减。整体而言, 多目标追踪中存在基于运动信息的自动化分组效应, 并且这一效应是格式塔法则中共同命运律的具体表现, 能稳定存在于不同表面特征组合之间。

| Abstract: | The automatic grouping effect is the finding that inter-target grouping improves performance, while target-distractor grouping impairs performance during multiple object tracking (MOT). Many features can induce the automatic grouping effect, such as color, shape, interpolation, and symmetry. However, none of these features are spatial-temporal. Motion information is the principal spatial-temporal feature, and it plays an important role in multiple object tracking (MOT). Using motion information stored in visual spatial working memory (VSWM), people can not only keep track of multiple moving targets among identical distractors, but also periodically extrapolate the motion trajectory of targets. We investigated whether or not participants can use motion information as the basis of the automatic grouping effect just as they can with other feature (e.g. color, shape) during attention tracking. |
