Based on Pacherie's dynamic theory of intentions, this study investigated how the way an intention is formed and sustained affects action performance and the experience of control during acting. In Experiment 1, task-irrelevant verbal commands were given while participants responded to stimuli in a two-choice reaction time (RT) task. The commands referred to an action goal congruent or incongruent with the actor's current intention, or ordered the initiation or abortion of the action. In Experiment 2, the same commands were given as participants freely chose between two actions. The distractors affected performance in the reactive task only. In both experiments, feelings of control were based on movement parameters as well as perceived (mis)matches between distractors and intended actions. These findings suggest that the way an intention is implemented affects how well it can be shielded against external perturbations and how much one feels in control.
基于帕谢里的意图动态理论，本研究调查了意图形成和维持的方式如何影响行动表现以及行动过程中的控制体验。在实验1中，当参与者在二选一反应时（RT）任务中对刺激做出反应时，给出了与任务无关的言语指令。这些指令涉及与行动者当前意图一致或不一致的行动目标，或者命令行动的启动或中止。在实验2中，当参与者在两个行动之间自由选择时，给出了相同的指令。干扰因素仅影响反应性任务中的表现。在两个实验中，控制感都基于运动参数以及干扰因素与预期行动之间的感知（不）匹配。这些发现表明，意图的实施方式会影响其抵御外部干扰的能力以及个人的控制感。
