意向捆绑是指一种自愿行为与其感觉结果之间的时间吸引。自2002年被发现以来，它一直被认为是一种有效的内隐测量代理感(SoA)，因为它只发生在自愿行动的背景下。绝大多数考虑IB的研究都招募了年轻人作为参与者，而忽略了可能与年龄相关的差异。本研究旨在研究10岁儿童IB的发展状况。我们决定采用一种新的、更合适的范式来研究IB，以取代Libet的经典时钟方法，因为孩子们在处理阅读时钟方面可能会有一些困难。因此使用了一系列不可预测的字母：参与者必须记住当他们自愿采取行动、听到声音或感觉到右手食指被动向下移动时，屏幕上显示的是哪个字母。在实验一中，对一组年轻人进行了测试，以便用这种新的范式复制IB效应。在实验II中，同样的范式被应用到儿童身上，以调查这种影响是否已经在这个年龄出现。实验I的数据显示，成年人中存在IB效应。然而，实验II显示了IB的明显减少。两组的比较表明，青壮年组与儿童组不同，表现出明显更强的行为及其后果之间的联系。结果表明，IB效应有发展的趋势。根据额叶皮质网络的成熟过程对这一发现进行了讨论。
Intentional binding (IB) refers to the temporal attraction between a voluntary action and its sensory consequence. Since its discovery in 2002, it has been considered to be a valid implicit measure of sense of agency (SoA), since it only occurs in the context of voluntary actions. The vast majority of studies considering IB have recruited young adults as participants, while neglecting possible age-related differences. The aim of the present work is to study the development of IB in 10-year-old children. In place of Libet’s classical clock method, we decided to implement a new and more suitable paradigm in order to study IB, since children could have some difficulties in dealing with reading clocks. A stream of unpredictable letters was therefore used: participants had to remember which letter was on the screen when they made a voluntary action, heard a sound, or felt their right index finger moved down passively. In Experiment I, a group of young adults was tested in order to replicate the IB effect with this new paradigm. In Experiment II, the same paradigm was then administered to children in order to investigate whether such an effect has already emerged at this age. The data from Experiment I showed the presence of the IB effect in adults. However, Experiment II demonstrated a clear reduction of IB. The comparison of the two groups revealed that the young adult group differed from the children, showing a significantly stronger linkage between actions and their consequences. The results indicate a developmental trend in the IB effect. This finding is discussed in light of the maturation process of the frontal cortical network.
