Recent evidence suggests the existence of we-mode processing, but little is still known about how such processing influences the sense of control during intentional joint actions. To examine this issue, dyads performed a video game in which they moved a dot to the target of their choice out of a set of targets. By having each participant control the dot movements in only one dimension (orthogonal to their partner) and by varying the target locations, participants took on different roles. By chance, they also could have congruent or incongruent intentions prior to the movements. In a decider-follower scenario, where one actor decided on the target, judgments of control and judgments of performance depended on whether a prior intention was instantiated, but not on actor role. This finding is consistent with we-mode processing. When participants had conflicting intentions that needed to be resolved online, both the dominant and the nondominant participant showed a marked reduction in the perceived quality of the performance. Thus, dynamic intention negotiation reduced we-mode processing and shifted it toward I-mode processing. The nondominant actor also reported a strongly reduced sense of control. Implications for theories on the sense of agency and for applied settings are discussed.
最近的证据表明存在“我们模式”加工，但对于这种加工如何在有意的联合行动中影响控制感，我们仍知之甚少。为了研究这个问题，两人一组进行了一个电子游戏，在游戏中他们将一个点从一组目标中移动到自己选择的目标。通过让每个参与者仅在一个维度（与他们的伙伴垂直）上控制点的移动，并改变目标位置，参与者承担了不同的角色。偶然地，他们在移动之前也可能有一致或不一致的意图。在一个决策者-追随者的情境中，即一个参与者决定目标，控制判断和表现判断取决于先前的意图是否被实例化，而不取决于参与者的角色。这一发现与“我们模式”加工一致。当参与者有需要在线解决的冲突意图时，主导参与者和非主导参与者都表现出表现质量感知的显著下降。因此，动态意图协商减少了“我们模式”加工，并将其转向“我模式”加工。非主导参与者也报告说控制感大幅降低。本文还讨论了对能动性理论和应用场景的启示。
