We know a great deal about the neurophysiological mechanisms supporting instrumental actions, i.e., actions designed to alter the physical state of the environment. In contrast, little is known about our ability to select communicative actions, i.e., actions directly designed to modify the mental state of another agent. We have recently provided novel empirical evidence for a mechanism in which a communicator selects his actions on the basis of a prediction of the communicative intentions that an addressee is most likely to attribute to those actions. The main novelty of those findings was that this prediction of intention recognition is cerebrally implemented within the intention recognition system of the communicator, is modulated by the ambiguity in meaning of the communicative acts, and not by their sensorimotor complexity. The characteristics of this predictive mechanism support the notion that human communicative abilities are distinct from both sensorimotor and linguistic processes.
我们对支持工具性动作(即旨在改变环境物理状态的动作)的神经生理机制了解颇多。相比之下,我们对自身选择交际动作(即直接旨在改变另一个体心理状态的动作)的能力却知之甚少。我们最近为一种机制提供了新的实证证据,在这种机制中, communicator 根据对受话者最有可能赋予这些动作的交际意图的预测来选择自己的动作。这些发现的主要新颖之处在于,这种意图识别预测在 communicator 的意图识别系统中在大脑层面得以实现,由交际行为意义的模糊性而非其感觉运动复杂性进行调节。这种预测机制的特征支持了这样一种观点,即人类的交际能力既不同于感觉运动过程,也不同于语言过程。
