本研究考察了准备对线索任务转换抑制效应的影响。在三个实验中，我们通过比较任务序列中的表现，如ABA(即n 2次重复，A、B和C代表不同的任务)与任务序列如CBA(即n-2开关)，来评估n-2重复成本作为抑制刚刚执行的和现在无关的任务的标志。具体地说，我们改变了线索-目标间隔(CTI)来检查基于线索的准备效果。此外，我们还在三个实验中操纵了线索类型(即抽象线索、言语线索和直接线索)。当使用抽象线索(即彩色框架)和任务名称(即数字)时，我们通过延长CTI获得了显著的n-2重复成本，但当使用任务特定的刺激-反应映射作为即将到来的任务的线索时，我们没有得到显著的降低。这些数据表明，基于线索的准备不是一个统一的过程，而是取决于线索提供的信息。(C)2014爱思唯尔B.V.保留所有权利。
The present study investigates the influence of preparation on inhibitory effects in cued task switching. In three experiments, we assessed n - 2 repetition costs as marker of inhibition of the just executed and now irrelevant task by comparing performance in task sequences such as ABA (i.e., n 2 repetitions, with A, B and C standing for different tasks) to task sequences such as CBA (i.e., n - 2 switches). Specifically, we varied the cue-target interval (CTI) to examine cue-based preparation effects. In addition, we manipulated cue type (i.e., abstract, verbal, and direct cues) across the three experiments. We obtained significant reductions of n - 2 repetition costs with prolonged CTI when using abstract cues (i.e., coloured frames) and task names (i.e., digit), but not when using the task-specific stimulus-response mapping as cue for the upcoming task. These data suggest that cue-based preparation is not a uniform process but depends on the information provided by the cue. (c) 2014 Elsevier B.V. All rights reserved.
