项目摘要

Time perception in action settings is biased. Participants judge the occurrence of a voluntary action latter and the occurrence of a self-produced action effect earlier than the occurrence of an action without effect or the occurrence of a stimulus without prior action (e.g., Haggard, Aschersleben, Gehrke, & Prinz, 2002). This effect is called intentional binding effect and presumably occurs because of a binding mechanism that takes places between an intentional action and an intended effect. In the first project part, we applied a psychophysical method - the method of constant stimuli - to verify that the interval between action and effect is perceived shorter when an action causes an effect. With this method, we were able to demonstrate that action-effect intervals are perceived shorter irrespective of whether participants perform a voluntary action or a stimulus-instructed response to produce the effect. In addition, we demonstrated that time perception does not depend on whether the identity of the action effect or the action-effect interval is predictable or not. Finally, we showed that time perception in action settings is closely related to the feeling to have caused an effect, thus to sense of agency. In the second project phase, we aim to investigate whether time perception of action-effect intervals and sense of agency depend on the variability of action-effect episodes. Additionally, we aim to elaborate the impact of learning processes regarding the time point of an effect on time perception and sense of agency. And finally we are interested in the impact of top-down strategical knowledge on time perception of actions and effects.

动作情境中的时间知觉存在偏差。参与者判断自愿行动的发生较晚，自发行动效果的发生较早，而不是没有效果的行动的发生或没有先前行动的刺激的发生（例如，Haggard，Aschersleben，Gehrke，& Prinz，2002）.这种效果被称为有意的约束效果，并且可能是由于在有意的行为和预期的效果之间发生的约束机制而发生的。在项目的第一部分，我们应用了心理物理学的方法-恒定刺激的方法-来验证当一个动作引起一个效果时，动作和效果之间的间隔被感知得更短。通过这种方法，我们能够证明，无论参与者是否执行自愿行动或刺激指示的反应来产生效果，动作-效果间隔都被认为较短。此外，我们还证明了时间知觉不依赖于动作效应或动作效应间隔的同一性是否是可预测的。最后，我们表明，在行动设置的时间知觉是密切相关的感觉，造成了效果，从而代理感。在第二个项目阶段，我们的目标是调查是否时间知觉的动作效果间隔和代理感依赖于动作效果情节的变异性。此外，我们的目标是详细说明学习过程的时间点上的时间知觉和代理感的影响。最后，我们感兴趣的是自上而下的战略知识对行动和效果的时间知觉的影响。
