运动感知对于适应动态环境中的行为是必不可少的。许多研究表明，隐约可见的运动能吸引注意力，而后退的运动则不能，这突显了运动感知的行为紧迫性。本研究考察了在同时显示在视野中的多个心流的情况下，特定的定向心流是否能够吸引注意资源。结果表明，当两个方向相反的流动(隐约和后退)一起显示时，参与者可以更有效地辨别隐约运动中的目标。当呈现四个流(一个隐现三个后退或三个隐现一个后退)时，结果表明，显示在隐现流内的目标被更快地识别，但也表明通过后退运动可以吸引注意力。这表明，在一个隐约可见的心流中的过程更有效率，但这种效应不能归因于注意力集中过程。
Motion perception is essential to adapt behavior in a dynamic environment. Many studies have suggested that looming motion captures attention, whereas receding motion does not, highlighting the behavioral urgency of motion perception. The present study examined whether attentional resources can be attracted by a specific directed flow in the presence of multiple flows that are simultaneously displayed in the visual field. The results showed that when two flows of opposite direction (looming and receding) are displayed together, participants more efficiently discriminate the target inside the looming motion. When four flows are presented (one looming and three receding or three looming and one receding), the results showed that the target displayed inside the looming flow was more rapidly identified but also suggest that attention can be attracted by receding motion. This suggests that the process inside a looming flow is more efficient, but this effect could not be attributed to attentional focusing processes.
