Previous research suggests that motor actions are intentionally generated by recollecting their sensory consequences. Whereas this has been shown to apply to visual or auditory consequences in the environment, surprisingly little is known about the contribution of immediate, body-related consequences, such as proprioceptive and tactile reafferences. Here, we report evidence for a contribution of vibrotactile reafferences to action selection by using a response-effect compatibility paradigm. More precisely, anticipating actions to cause spatially incompatible vibrations delayed responding to a small but reliable degree. Whereas this observation suggests functional equivalence of body-related and environment-related reafferences to action control, the future application of the described experimental procedure might reveal functional peculiarities of specific types of sensory consequences in action control.
先前的研究表明，运动动作是通过回忆其感觉后果而有意产生的。虽然这已被证明适用于环境中的视觉或听觉后果，但令人惊讶的是，对于即时的、与身体相关的后果，如本体感觉和触觉再传入的贡献却知之甚少。在这里，我们通过使用反应-效应兼容性范式报告了振动触觉再传入对动作选择有贡献的证据。更确切地说，预期动作会导致空间上不兼容的振动会在一定程度上延迟反应，虽然幅度较小但可靠。虽然这一观察结果表明与身体相关和与环境相关的再传入在动作控制方面具有功能等效性，但所描述的实验程序的未来应用可能会揭示特定类型的感觉后果在动作控制中的功能特性。
