The cues contributing to people's metacognitions of agency were investigated in two experiments in which people played a computer game that involved trying to "touch", via a mouse moving a cursor, downward scrolling X's (Experiment 1), or trying to "explode" the downward scrolling X's (Experiment 2). Both experiments varied (a) proximal action-related information by either introducing or not introducing Turbulence into the mouse controls and (b) distal outcome-related information such that touched X's "exploded" either 100 or 75 % of the time. Both variables affected people's judgments of agency (JOAs), but the effect was different. First, the decrement in feelings of agency was greater with the proximal variable than with distal variable. Second, while the proximal variable always had a large direct effect on JOAs, even taking judgments of performance (JOPs) into account, JOPs completely accounted for the effect of the distal variable in Experiment 1, where the instructions were just to touch the X's. And even in Experiment 2, in which the instructions were to explode the X's, the direct effect of the distal variable on JOAs was small. These data indicate that these two cues exhibit different psychological profiles. The proximal action-related information is a diagnostic cue to agency indicating the match between one's own intentions and actions. Internal monitoring of intentions is necessary and so the self is implicated. However, distal outcome can be largely monitored using information external to the agent, and so-while it is used by people to make agency judgments-it is a non-diagnostic cue.
两个实验考察了促使人们对代理权进行元认知的线索,在这两个实验中,人们玩了一个电脑游戏,通过鼠标移动光标来尝试“触摸”向下滚动的 X(实验 1),或尝试“爆炸”向下滚动的 X(实验 2)。两个实验都改变了(a)近端动作相关信息,要么引入波动,要么不引入鼠标控制;(b)远端结果相关信息,使得触摸 X 的“爆炸”概率为 100%或 75%。这两个变量都影响了人们对代理权的判断(JOA),但效果不同。首先,近端变量对代理权的削弱作用大于远端变量。其次,虽然近端变量总是对 JOA 有很大的直接影响,即使考虑到对表现的判断(JOP),JOP 也完全解释了在实验 1 中远端变量的影响,在实验 1 中,只是指示触摸 X。即使在实验 2 中,指令是爆炸 X,远端变量对 JOA 的直接影响也很小。这些数据表明,这两个线索表现出不同的心理特征。近端动作相关信息是代理的诊断线索,表明自己的意图和行动之间的匹配。对意图的内部监控是必要的,因此自我也被牵连进来。然而,远端结果可以通过代理人之外的信息进行很大程度的监控,因此,尽管人们用它来做出代理权判断,但它是非诊断性线索。
