Figure captionsFigure S1. Strength of the inter-limb interference following instructions to direct attention to both sides regardless of the AC (Experiment 1). Under the C-VF condition, the inter-limb couplings were relatively stronger than those in the S-VF condition. Additionally, when the participants were required to always direct their attention to both sides regardless of the AC location, the couplings did not vary depending on AC location under the S-VF condition [F(2,30) = 0.062, p = 0.94, ηp2 = 0.0041 for the AC locations; F(1,15) = 1.46, p = 0.25, ηp2 = 0.089 for the interfered side; and F(2,30) = 0.85, p = 0.44, ηp2 = 0.054 for the interaction] or the C-VF condition [F(2,30) = 0.21, p = 0.81, ηp2 = 0.014 for the AC locations; F(1,15) = 0.092, p = 0.77, ηp2 = 0.0061 for the interfered side; and F(2,30) = 0.96, p = 0.39, ηp2 = 0.060 for the interaction]. Error bars indicate the standard deviation across participants.Figure S2. Percentage of the parallel-asymmetric response when directing attention to the left task space. a: When the participants corrected with their left hand, the responses did not significantly change (Bonferroni multiple comparison tests, between “HCL-OBJL” and “HCL-OBJR”: p = 0.38; between “HCR-OBJL” and “HCL-OBJR”: p = 0.059; and between “HCL-OBJL” and “HCR-OBJL”: p = 0.99) b: When the participants corrected with their right hand, there was a higher percentage of parallel asymmetric responses under the HCR-OBJL visual configuration in which the operation object was shown in the left space (Bonferroni multiple comparison tests, between “HCL-OBJL” and “HCL-OBJR”: p = 0.82; between “HCR-OBJL” and “HCL-OBJR”: p = 0.0021; and between “HCL-OBJL” and “HCR-OBJL”: p = 0.030). Error bars indicate the standard deviation across participants. †p p p图注：补充图S1：无论注意线索（Attention Cue, AC）位置如何，被要求将注意力分配至双侧时的肢体间干扰强度（实验1）。在C-VF条件下，肢体间耦合强度相对S-VF条件更强。此外，当被试被要求无论注意线索位置如何，均需将注意力分配至双侧时，在S-VF条件下，肢体间耦合未随注意线索位置发生显著变化[注意线索位置主效应：F(2,30)=0.062, p=0.94, ηp²=0.0041；受干扰侧主效应：F(1,15)=1.46, p=0.25, ηp²=0.089；交互效应：F(2,30)=0.85, p=0.44, ηp²=0.054]；在C-VF条件下同样未出现显著变化[注意线索位置主效应：F(2,30)=0.21, p=0.81, ηp²=0.014；受干扰侧主效应：F(1,15)=0.092, p=0.77, ηp²=0.0061；交互效应：F(2,30)=0.96, p=0.39, ηp²=0.060]。误差棒表示被试间的标准差。补充图S2：仅将注意力指向左侧作业空间时的平行不对称响应占比。a：当被试使用左手进行修正操作时，响应占比无显著变化（Bonferroni多重比较检验："HCL-OBJL"与"HCL-OBJR"组间p=0.38；"HCR-OBJL"与"HCL-OBJR"组间p=0.059；"HCL-OBJL"与"HCR-OBJL"组间p=0.99）。b：当被试使用右手进行修正操作时，在操作对象呈现于左侧空间的HCR-OBJL视觉配置下，平行不对称响应占比更高（Bonferroni多重比较检验："HCL-OBJL"与"HCL-OBJR"组间p=0.82；"HCR-OBJL"与"HCL-OBJR"组间p=0.0021；"HCL-OBJL"与"HCR-OBJL"组间p=0.030）。误差棒表示被试间的标准差。†p p p
