The subjective experience of conscious intention is a key component of our mental life. Philosophers studying 'conscious free will' have discussed whether conscious intentions could cause actions, but modern neuroscience rejects this idea of mind-body causation. Instead, recent findings suggest that the conscious experience of intending to act arises from preparation for action in frontal and parietal brain areas. Intentional actions also involve a strong sense of agency, a sense of controlling events in the external world. Both intention and agency result from the brain processes for predictive motor control, not merely from retrospective inference.
有意识意图的主观体验是我们精神生活的关键组成部分。研究“有意识自由意志”的哲学家们讨论过有意识意图是否能引发行动,但现代神经科学摒弃了这种身心因果关系的观点。相反,最近的研究结果表明,有意行动的有意识体验源于额叶和顶叶脑区对行动的准备。有意行动还涉及强烈的能动感,即控制外部世界事件的感觉。意图和能动感都源于大脑用于预测性运动控制的过程,而不仅仅来自追溯推理。
