使用提示听觉任务切换的二元聆听变体，我们改变了反应-提示间隔（RCI）来检验时间耗散效应。在每次试验中，参与者都会听到两个不同的数字词，一个是由女性说话者说的，另一个是由男性说话者说的（二分聆听），这两个词作为数字判断的竞争目标。在每次试验之前，通过视觉任务提示来指示与任务相关的说话者的性别。实验1A对每个任务（即性别）使用了两个不同的线索，并且只显示了小的线索重复效益（相同线索vs.替代线索），但大的听觉转换成本（替代线索vs.任务切换）。没有即时提示重复的重复实验（实验1B）显示了非常相似的转换成本，这表明即时提示重复对听觉任务转换成本的影响可以忽略不计。此外，当与任务相关的说话者（完全与任务无关）的位置发生变化时，转换成本相对于不变时有所降低，这表明在我们的二元听力任务中存在情景特征绑定成分。重要的是，两个实验都没有显示RCI对听觉转换成本的影响。因为这个零效应的统计能力在实验中相当高（n = 50），这一发现表明听觉注意力设置不会随着时间的推移而迅速消散。
Using a cued auditory task-switching variant of dichotic listening, we varied the response–cue interval (RCI) to examine temporal dissipation effects. On each trial, participants were presented with two different number words, one spoken by a female speaker and another by a male speaker (dichotic listening), that served as competing targets for a numerical judgment. The gender of the task-relevant speaker was indicated by a visual task cue prior to each trial. Experiment 1A used two different cues for each task (i.e., gender) and showed only small cue repetition benefits (same cue vs. alternate cue) but large auditory switch costs (alternate cue vs. task switch). A replication without immediate cue repetitions (Experiment 1B) showed very similar switch costs, suggesting that immediate cue repetitions play a negligible role for the size of auditory task switch costs. Moreover, switch costs were reduced when the (entirely task-irrelevant) location of the task-relevant speaker changed, relative to when it was unchanged, suggesting an episodic feature-binding component in our dichotic-listening task. Importantly, both experiments showed no effect of RCI on auditory switch costs. Because statistical power for this null effect was reasonably high across experiments (n = 50), this finding suggests that auditory attention settings do not dissipate quickly over time.
