Implicit (unconscious) and explicit (strategy) processes have been shown to contribute to visuomotor adaptation. Current methods, such as the Process Dissociation Procedure (PDP) and the Verbal Report Framework (VRF), simultaneously evaluate both implicit and explicit contributions to visuomotor adaptation. It is unclear whether the act of assessing explicit adaptation leads to variations in the magnitude of implicit adaptation observed. To address this question, four groups of participants adapted their reaches to a 40° clockwise visuomotor rotation. Implicit and explicit adaptation were assessed in a PDP-IE group and a VRF-IE group following 3 blocks of rotated reach training trials. In contrast, only implicit adaptation was assessed at the same time points for a PDP-I group and VRF-I group. Results indicated a similar magnitude of implicit adaptation regardless of whether explicit adaptation was assessed or not. Thus, assessing explicit adaptation simultaneously with implicit adaptation following reach adaptation does not influence the magnitude of implicit adaptation established via the PDP and VRF methods.
内隐（无意识）和外显（策略）过程已被证明有助于视动适应。目前的方法，如过程分离程序（PDP）和言语报告框架（VRF），同时评估对视动适应的内隐和外显贡献。目前尚不清楚评估外显适应的行为是否会导致观察到的内隐适应幅度的变化。为了解决这个问题，四组参与者适应了他们的伸手去适应 40°顺时针视动旋转。在 3 个旋转伸手训练试验块后，在 PDP-IE 组和 VRF-IE 组中评估内隐和外显适应。相比之下，对于 PDP-I 组和 VRF-I 组，仅在相同的时间点评估内隐适应。结果表明，无论是否评估外显适应，内隐适应的幅度相似。因此，在进行伸手适应后，同时评估外显适应和内隐适应不会影响通过 PDP 和 VRF 方法建立的内隐适应幅度。
