中文摘要 | Voluntary action is important for human to adapt and change outside world. Voluntary action has an concomitant effect -- the temporal interval between an action and its outcome is subjectively compressed, known as intention binding. Most studies on intentional binding examined whether action is self-generated, but whether the outcome is self-related has not been paid much attention. At present, the main models or mechanisms of theoretical interpretation do not explicitly discuss the role of self-related information, and there is some confusion with anticipation, causality and expectation. Study 1 systematically examined the effect of self-related information on intentional-binding in the behavior experiment. Participants completed a time interval estimation task and a time point estimation task. Since the result type of action was unpredictable, there was no causal relationship with the action behavior. In study 2, the brain mechanism of time interval estimation task and time point estimation task was studied by EEG technology. This study draws the following main results: The study found different self-related information may affect time perception and sense of agency.It is not only the self-relevance voluntary actions affects intention binding, but also the self-relevance outcomes. These results suggest that postdictive explanatory mechanisms may play an important role in intentional binding, independent of causality and expectation. Through Libet clock task, self-related information effects outcome binding morethan action binding. In the EEG, P2/P3 at least partially reflected the differencebetween self-related information and non-self-related information in the sense ofagency. The midline electrode of EEG may play an important role in cognitiveprocessing. In this study, the influence and neural mechanism of self-related information insense of agency can be explored to enrich and improve the theoretical basis of sense of agency, which can help to further understand the internal mechanism of self-relatedinformation. |
英文摘要 | 主动动作是人类主动适应和改变环境的重要手段。主动动作有一个重要的伴随效应——动作和结果之间的时间产生主观压缩,被称为意图绑定效应。大多数关于意图绑定效应的研究都在考察动作是自我产生,但结果是否与自我有关却鲜被关注。目前理论解释的主要理论也没有明确讨论自我关联信息的作用,并与意向性、因果性和预期存在一定的混淆。 研究一采用行为实验考察了自我关联信息对意图绑定效应的影响。被试需完成时间间隔估计任务和时间点估计任务,由于任务的结果类型是不可预测的,与动作行为没有因果关系。研究二在研究一的基础上,通过脑电技术来研究时间间隔估计任务和时间点估计任务所对应的脑机制。 本研究得出以下主要结果: 1. 研究发现不同的自我关联信息可能会影响时间知觉和主动控制感。不仅是以往研究发现的主动动作的自我关联性会影响意图绑定效应,结果本身的自我关联性也会影响意图绑定效应。 2. 通过时间点估计任务发现,自我关联信息的影响可能相较于动作绑定而言更多是发生在结果绑定阶段。这个结果说明事后解释机制在意图绑定效应和自我意识中可能发挥着重要的作用,这一机制独立于因果关系和预期。在脑电上P2/P3 至少部分反映了被试在自我关联信息和非自我关联信息在主动控制感中的差异,脑电的中线电极在认知加工过程中可能发挥重要的作用。 本研究通过探究自我关联信息在主动控制感中作用的影响和神经机制,可以丰富和完善主动控制感的理论基础,有助于进一步了解自我关联信息影响主动控制感的内在机制。 |
