最近的方法论进展使研究人员能够通过将线索切换与任务切换分离来解决任务切换性能中任务切换成本测量中的混淆问题。例如，在转换提示过程中，涉及为任务转换而不是任务呈现提示，可以在完整的析因设计中检查提示转换（提示切换和提示重复）和任务转换（任务切换和任务重复）。转换提示消除了提示转换和一阶任务转换之间的混淆，但它引入了提示转换和较长任务序列之间的混淆。在本研究中，对每个转换有两个提示的转换提示进行了研究（重复和再次用于任务重复；切换和更改用于任务切换），从而能够部分消除提示转换和任务序列的混淆。两项实验揭示了强大的顺序效应，当提示转换保持不变时，高阶任务转换会影响性能，而当任务序列保持不变时，提示转换会影响性能。讨论了这些发现对任务切换研究的方法论和理论意义。
Recent methodological advances have allowed researchers to address confounds in the measurement of task-switch costs in task-switching performance by dissociating cue switching from task switching. For example, in the transition-cuing procedure, which involves presenting cues for task transitions rather than for tasks, cue transitions (cue switches and cue repetitions) and task transitions (task switches and task repetitions) can be examined in a complete factorial design. Transition cuing removes the confound between cue transitions and first-order task transitions, but it introduces a confound between cue transitions and longer task sequences. In the present study, transition cuing was studied with two cues per transition (REPEAT and AGAIN for task repetitions; SWITCH and CHANGE for task switches), enabling a partial deconfounding of cue transitions and task sequences. Two experiments revealed robust sequential effects, with higher order task transitions affecting performance when cue transitions were held constant and with cue transitions affecting performance when task sequences were held constant. Methodological and theoretical implications of these findings for research on task switching are discussed.
