There is debate about how implicit and explicit processes interact in sensorimotor adaptation, implicating how error signals drive learning. Target error information is thought to primarily influence explicit processes, therefore manipulations to the veracity of this information should impact adaptation but not implicit recalibration (i.e. after-effects). Thirty participants across three groups initially adapted to rotated cursor feedback. Then we manipulated numeric target error through knowledge of results (KR) feedback, where groups practised with correct or incorrect (+/-15°) numeric KR. Participants adapted to erroneous KR, but only the KR + 15 group showed augmented implicit recalibration, evidenced by larger after-effects than before KR exposure. In the presence of sensory prediction errors, target errors modulated after-effects, suggesting an interaction between implicit and explicit processes.
关于内隐和外显过程在感觉运动适应中如何相互作用存在争议，这涉及到错误信号如何驱动学习。目标误差信息被认为主要影响外显过程，因此对该信息的准确性进行操纵应该会影响适应，但不会影响内隐的重新校准（即后效）。最初有 30 名参与者分为三组适应旋转光标反馈。然后，我们通过结果知识（KR）反馈来操纵数字目标误差，其中各组分别使用正确或错误（+/-15°）的数字 KR 进行练习。参与者适应了错误的 KR，但只有 KR + 15 组表现出增强的内隐再校准，这表现为后效比 KR 暴露前更大。在存在感觉预测误差的情况下，目标误差调节了后效，这表明内隐和外显过程之间存在相互作用。
