摘要

Previous studies have suggested that sensorimotor communication promotes joint action. However, the studies were mixed with feedback factor. So the present study questions that result. The present study explores this question using two experiments based on asymmetric alternating joint action. Experiment 1 used a 2 (task: baseline, asymmetric alternating joint action) × 4 (target location: T1, T2, T3, T4) within-subjects design to examine the performance of asymmetrical alternating joint action with and without sensorimotor communication in 62 (30 males, 32 females) college students. It was found that, without feedback, the information sender increased the target key dwell time sequentially in the order of " up left, up right, down left, down right " to establish a sensorimotor communication pattern, which facilitated the achievement of asymmetric joint action. Experiment 2 used a 2 (task: baseline, asymmetric alternating joint action) × 2 (feedback: feedback, no-feedback) × 4 (target location: T1, T2, T3, T4) mixed design to further investigate the effect of feedback on asymmetric alternating joint action. Examined the asymmetric alternating joint action performance of 170 (84 male, 86 female) college students. The results indicate that sensorimotor communication and feedback jointly facilitate interpersonal motor coordination, feedback plays a key role. Specifically, without feedback, sensorimotor communication facilitates information transfer by establishing specific patterns based on sensorimotor experiences and verbal metaphors. With feedback, feedback facilitates information transfer by updating and optimizing sensorimotor communication patterns.
