线索有助于检索和执行任务集，这些任务集是工作记忆中待执行任务的实际表示。然而，尽管先前的研究表明，基于线索选择和执行任务集的有效性取决于线索的类型（即，透明词与任意形状），仍然不清楚线索的哪些特征是造成这些差异的原因，以及线索的影响是仅限于任务集检索还是也影响任务集表征。例如，在实际的任务性能的干扰量已被报告改变依赖于线索类型做准备收益，如减少开关成本。为了研究线索特征的有效性（即，线索透明度和线索格式），我们操纵那些内部和之间的参与者在三个实验。主要的依赖措施是转换成本的反应时间和错误率时，发生的参与者切换任务集，从而更新工作记忆的内容。我们的研究结果一致表明，有益的影响，透明的线索，减少开关成本。提示格式的影响仅表现在被试内操作上，主要表现在错误率上。总的来说，我们的数据表明，在实际的任务表现所经历的干扰量可以显着调制依赖于线索类型，这表明灵活的适应的认知系统的上下文信息。
Cues help in retrieving and implementing task-sets, that are actual representations of the to-be performed task in working memory. However, whereas previous studies revealed that the effectiveness of selecting and implementing task-sets based on cues depends on the type of cue (i.e., transparent words vs. arbitrary shapes), it is still unclear which characteristics of cues are responsible for these differences and whether the impact of the cue is bound to task-set retrieval only or also impacts task-set representations. For instance, the amount of interference during actual task performance has been reported to alter dependent on cue type as do preparation gains such as the reduction of switch cost. To investigate the effectiveness of cue characteristics (i.e., cue transparency and cue format), we manipulated those within- and between-participants in three experiments. Main dependent measures were switch costs in reaction times and error rates that occur when participants have to switch task-sets, and thus update working memory content. Our results consistently show beneficial effects of transparent cues for the reduction of switch cost. The influence of cue format was manifest in within-participants manipulation only and was mainly found in error rates. Overall, our data suggest that the amount of interference experienced in actual task performance can be significantly modulated dependent on cue type, suggesting flexible adaptation of the cognitive system to contextual information.
