与外部产生的相同效果相比，由自己的行为产生的感官效果的感知通常会减弱。然而，目前还不清楚这是否与自我生成有关。最近的研究表明，感觉衰减主要依赖于动作准备，而不是实际的动作执行。因此，如果可以预期这些动作，那么就可能会发生另一个人产生的感觉效果的衰减。在这里，我们比较了由自己的动作和另一个人的动作产生的声音的感知响度，这些动作可以或不能被预期。我们发现，与其他产生的声音相比，自我感知的响度衰减。这种差异与另一个人的声音诱发行为是否可以预期无关。因此，感觉衰减似乎与自我生成特别相关，而不是为即将到来的行动做独立于代理人的准备的次要效果。(C)2012 Elsevier Inc.

The perception of sensory effects generated by one's own actions is typically attenuated compared to the same effects generated externally. However, it is unclear whether this specifically relates to self-generation. Recent studies showed that sensory attenuation mainly relies on action preparation, not actual action execution. Hence, an attenuation of sensory effects generated by another person might occur if these actions can be anticipated and thus be prepared for.Here, we compared the perceived loudness of sounds generated by one's own actions and actions of another person that either could or could not be anticipated. We found an attenuation of the perceived loudness for self- as compared to other-generated sounds. This difference was independent of whether the sound-eliciting actions of the other person could be anticipated or not. Thus, sensory attenuation seems to be specifically tied to self-generation instead of being a secondary effect of agent-independent preparation for an upcoming action. (C) 2012 Elsevier Inc.
