我们感知外部产生和自身产生的感觉刺激的能力可以通过训练来增强，这种训练被称为被动和主动感知学习(APL)。在这里，我们试图通过使用主动触觉训练(AHT)来探索APL的潜在机制，该训练已被证明在训练的运动技能中增强了手指的体感知觉。共有120名钢琴家参与了这项研究。首先，AHT重组了钢琴击键时的肌肉协调性。第二，与预测信息相比，AHT增加了对传入感觉信息的相对依赖，而总体知觉敏感度没有增加。最后，AHT改进了对按键的反馈运动控制。这些结果表明，APL涉及对预测性感觉整合的主动探索和适应，这是训练有素的个体主动感知和反馈控制运动共同增强的基础。
Our ability to perceive both externally generated and self-generated sensory stimuli can be enhanced through training, known as passive and active perceptual learning (APL). Here, we sought to explore the mechanisms underlying APL by using active haptic training (AHT), which has been demonstrated to enhance the somatosensory perception of a finger in a trained motor skill. In total 120 pianists participated in this study. First, AHT reorganized the muscular coordination during the piano keystroke. Second, AHT increased the relative reliance on afferent sensory information relative to predicted one, in contrast to no increment of overall perceptual sensitivity. Finally, AHT improved feedback movement control of keystrokes. These results suggest that APL involves active exploration and adaptation of predictive sensory integration, which underlies the co-enhancement of active perception and feedback control of movements of well-trained individuals.
