动作效应的感觉处理已经被证明不同于外部触发的刺激，关于其发生的感知时间（有意绑定）和其强度（感觉衰减）。这些现象通常归因于前向行为模型，当行为预测与我们环境的变化一致时，我们对这些影响的体验就会改变。虽然近年来在理解感觉衰减和有意结合方面取得了很大进展，但有关所涉及的预测机制的确切性质的一些重要问题仍然没有答案。此外，这些机制往往没有在实证文件中讨论，对这些问题的全面审查尚未出现。本文试图填补这一空白。我们系统地研究了时间预测，时间控制，身份预测和运动预测在以前发表的报告中的感觉衰减和有意绑定的作用。通过分离先前已经对比的个体过程，并将这些实验与时间注意力和刺激期望的相关领域的研究相结合，我们评估了现有数据在多大程度上为正向动作模型在这些现象中的作用提供了证据。我们进一步提出了一些未来研究的途径，这可能有助于更好地确定运动预测在处理自愿行动效应中的作用，以及提高对这些现象如何适合一般预测处理框架的理解。此外，我们的分析对理解精神分裂症的代理障碍具有重要意义。
Sensory processing of action effects has been shown to differ from that of externally triggered stimuli, with respect both to the perceived timing of their occurrence (intentional binding) and to their intensity (sensory attenuation). These phenomena are normally attributed to forward action models, such that when action prediction is consistent with changes in our environment, our experience of these effects is altered. Although much progress has been made in recent years in understanding sensory attenuation and intentional binding, a number of important questions regarding the precise nature of the predictive mechanisms involved remain unanswered. Moreover, these mechanisms are often not discussed in empirical papers, and a comprehensive review of these issues is yet to appear. This review attempts to fill this void. We systematically investigated the role of temporal prediction, temporal control, identity prediction, and motor prediction in previous published reports of sensory attenuation and intentional binding. By isolating the individual processes that have previously been contrasted and incorporating these experiments with research in the related fields of temporal attention and stimulus expectation, we assessed the degree to which existing data provide evidence for the role of forward action models in these phenomena. We further propose a number of avenues for future research, which may help to better determine the role of motor prediction in processing of voluntary action effects, as well as to improve understanding of how these phenomena might fit within a general predictive processing framework. Furthermore, our analysis has important implications for understanding disorders of agency in schizophrenia.
