Residual switch costs are notoriously difficult to eliminate. Yet Hunt and Klein (2002) eliminated them in a task that required observers to alternate between 8 trials of prosaccades and 8 trials of antisaccades, as long as there was at least 1 sec between the task cue and the onset of the saccade target. It was proposed that the elimination of residual switch costs occurred because prosaccade responses are computed very rapidly. These so-called hypercompatible responses bypass memory retrieval stages of the response process, thereby eliminating the source of residual switch costs. Here we tested this hypothesis by requiring observers to alternate between responding with the finger that was vibrated (another task that meets the criteria for hypercompatibility) and responding with the finger of the opposite hand. Residual switch costs were not eliminated, suggesting that their elimination in Hunt and Klein (2002) was due to special properties of the prosaccade-antisaccade task.
众所周知，残余切换成本很难消除。然而，亨特和克莱因（2002年）在一项任务中消除了它们，该任务要求观察者在8次前扫视试验和8次反扫视试验之间交替进行，只要任务提示与扫视目标出现之间至少有1秒的时间。有人提出，残余切换成本的消除是因为前扫视反应的计算非常迅速。这些所谓的超兼容反应绕过了反应过程中的记忆检索阶段，从而消除了残余切换成本的来源。在这里，我们通过要求观察者在被振动的手指做出反应（另一项符合超兼容性标准的任务）和用另一只手的手指做出反应之间交替进行，来检验这一假设。残余切换成本并未消除，这表明在亨特和克莱因（2002年）的研究中，它们的消除是由于前扫视-反扫视任务的特殊性质。
