这项研究探索了超越个人目标的社会协调信息是否归因于简单几何形状产生的贫穷运动。我们通过呈现两个追逐者和一个共同的目标进行协调或个别(即非协调)追逐来操纵协调信息，并测量与理解社会互动相关的MU节律(感觉运动区8-13赫兹范围内的脑电振荡)。我们发现，虽然被试的任务与加工追逐动作完全无关，但协调追逐比控制条件(向后重放的追逐动作)对Mu节律的抑制作用更强，而不协调追逐的这种影响消失了。此外，单位抑制随着社会协调测验后评分的提高而增加，但与不协调的信息无关。这种影响不能用一般的注意力参与来解释，因为在不同条件下，与注意力相关的枕叶阿尔法抑制没有差异。这些发现与处理协调动作的解释一致，表明我们的视觉系统可以自动将社会协调信息归因于运动，至少在追逐场景时是这样。
This study explored whether social coordination information that extends beyond individual goals is attributed to impoverished movements produced by simple geometric shapes. We manipulated coordination information by presenting two chasers and one common target performing coordinated or individual (i.e., uncoordinated) chases, and measured mu rhythms (electroencephalogram oscillations within the 8–13 Hz range at sensorimotor regions) related to understanding social interactions. We found that although the participants’ task was completely unrelated to processing chasing motion, mu rhythms were more suppressed for coordinated chasing than in the control condition (backward replay for chasing motion), and this effect disappeared for uncoordinated chasing. Moreover, mu suppression increased with higher post-test ratings of social coordination but did not correlate with uncoordinated information. Such effects cannot be explained by general attentional involvement, as there was no difference in attention-related occipital alpha suppression across conditions. These findings are consistent with interpretations of processing coordinated actions, suggesting that our visual system can automatically attribute social coordination information to motion, at least in chasing scenes.
