受试者估计的时间意图执行的行动，行动本身，或听觉效果的行动。在行为和随后的效果之间发生的感知吸引或约束效果。对意图的判断并没有表现出这种约束力，这表明它们是独立于行动及其效果的。在额外的不可预测的判断条件下，受试者仅在每次试验后才被指示判断这些事件中的哪一个，从而阻碍了对特定事件的集中注意。发现了更强的约束效应，意图、行动和效果在时间上融合到一个单一的中心点。在控制任务中，受试者按顺序报告第一个或第二个音调的时间。当受试者事先知道要判断哪个音调时，音调序列没有表现出任何约束力，但当要判断的事件不可预测时，音调序列表现出与动作相同的融合。动作和效果的结合，而不是音调序列的结合，是预先注意和自动发生的。这些数据与行动后实施的重建过程相一致，这产生了一种连贯的主体感。然而，只有当我们的行动使其适当时，才应启动这一进程。我们认为，这种机制是触发提前传出处理。这一结论得到了进一步的研究支持，在去传入受试者IW。这个受试者表现出对一个动作的音调的正常约束，尽管他对这个动作的体验是前运动的，而不是外周起源的。有意行动的经验涉及前运动和重建过程之间的相互作用。(c)2006年爱思唯尔公司All rights reserved.
Subjects estimated the time of intentions to perform an action, of the action itself, or of an auditory effect of the action. A perceptual attraction or binding effect occurred between actions and the effects that followed them. Judgements of intentions did not show this binding, suggesting they are represented independently of actions and their effects. In additional unpredictable judgement conditions, subjects were instructed only after each trial which of these events to judge, thus discouraging focussed attention to a specific event. Stronger binding effects were found, with intention, action and effect fusing to a single central point in time. In a control task, subjects reported the time of the first or second tone in sequence. Tone sequences showed no binding at all when subjects knew in advance which tone to judge, but showed the same fusion as actions when the event to be judged was not predictable. Binding of actions and effects, but not of tone sequences, occurs pre-attentively, and automatically. The data are consistent with a reconstructive process, implemented after actions, which generates a coherent sense of agency. However, this process should only be triggered only when our actions make it appropriate. We suggest that this mechanism is triggered in advance by efferent processing. This conclusion was supported by a further study in deafferented subject IW. This subject showed the normal binding of a tone towards an action, although his experience of the action was of pre-motor, rather than peripheral origin. The experience of intentional action involves an interplay between pre-motor and reconstructive processes. (c) 2006 Elsevier Inc. All rights reserved.
