虽然内隐运动适应是由感觉预测误差（SPE）驱动的，但最近的研究表明，任务成功调节这一过程。任务成功通常被定义为击中目标，这意味着运动的目标。视觉适应任务的独特之处在于通过改变目标的大小或位置来独立于SPE实验性地操纵任务成功。这两种不同的操作可能以不同的方式影响内隐运动适应，因此，在四个实验中，我们试图探索每种操作的功效。我们发现，目标大小的变化，这导致目标完全包围光标，只影响内隐适应范围狭窄的SPE大小，而跳跃的目标与光标重叠更可靠，更强大的影响内隐适应。两者合计，我们的数据表明，虽然任务成功施加一个小的影响，内隐适应，这些影响是容易受到方法的变化。未来的调查任务成功的影响内隐适应可能受益于采用目标跳跃操纵而不是目标大小manipulations.NEW & NOTEWORTHY最近的工作表明，任务成功，即击中目标，影响内隐运动适应。在这里，我们观察到，隐式适应调制的目标跳跃操作，其中的目标突然“跳跃”，以满足光标;然而，隐式适应只有微弱调制的目标大小的操作，其中一个静态的目标，要么不包括或排除光标。我们将讨论这些操作如何通过不同的机制发挥其作用。
Although implicit motor adaptation is driven by sensory-prediction errors (SPEs), recent work has shown that task success modulates this process. Task success has typically been defined as hitting a target, which signifies the goal of the movement. Visuomotor adaptation tasks are uniquely situated to experimentally manipulate task success independently from SPE by changing the target size or the location of the target. These two, distinct manipulations may influence implicit motor adaptation in different ways, so, over four experiments, we sought to probe the efficacy of each manipulation. We found that changes in target size, which caused the target to fully envelop the cursor, only affected implicit adaptation for a narrow range of SPE sizes, while jumping the target to overlap with the cursor more reliably and robustly affected implicit adaptation. Taken together, our data indicate that, while task success exerts a small effect on implicit adaptation, these effects are susceptible to methodological variations. Future investigations of the effect of task success on implicit adaptation could benefit from employing target jump manipulations instead of target size manipulations.NEW & NOTEWORTHYRecent work has suggested that task success, namely, hitting a target, influences implicit motor adaptation. Here, we observed that implicit adaptation is modulated by target jump manipulations, where the target abruptly “jumps” to meet the cursor; however, implicit adaptation was only weakly modulated by target size manipulations, where a static target either envelops or excludes the cursor. We discuss how these manipulations may exert their effects through different mechanisms.
