在这一系列的行为实验中，我们研究了分散注意力对短期记忆中声音场景信息维持的影响。刺激是由几个（多达12个）并发的音调流（“源”）组成的人工声学“场景”。间隙（1000毫秒）插入中途通过“场景”;变化的形式出现一个新的来源或消失的现有来源，发生差距后的50%的审判。听众被指示监视这些事件的展开“音景”。通过在差距期间呈现分心物刺激来测量分心。实验1和2使用了双任务设计，要求听众执行任务，不同的注意力需求（“高需求”与“低需求”）的简短的听觉（实验1a）或视觉（实验1b）信号期间提出的差距。实验2和3要求参与者忽略干扰声音，专注于变化检测任务。我们的研究结果表明，在短期记忆中的场景信息的维护的影响，注意和/或加工资源的可用性期间的差距，这种依赖性似乎是特定的通道。我们还表明，这些过程容易受到自下而上驱动的分心，即使在情况下，分心是不是新的，但发生在每次审判。变化检测性能系统地与独立确定的干扰音的感知显著性相关联。研究结果还表明，本任务可能是一个有用的客观手段，确定相对知觉显著性。分心是通过在场景间隙期间呈现分心物刺激来测量的。存储器中的场景维护取决于差距期间资源的可用性。这种依赖性似乎是特定的模式。场景维护也倾向于自下而上的分心，即使分心不是新颖的。表现取决于干扰音的知觉显著性。
In this series of behavioural experiments we investigated the effect of distraction on the maintenance of acoustic scene information in short-term memory. Stimuli are artificial acoustic ‘scenes’ composed of several (up to twelve) concurrent tone-pip streams (‘sources’). A gap (1000 ms) is inserted partway through the ‘scene’; Changes in the form of an appearance of a new source or disappearance of an existing source, occur after the gap in 50% of the trials. Listeners were instructed to monitor the unfolding ‘soundscapes’ for these events. Distraction was measured by presenting distractor stimuli during the gap. Experiments 1 and 2 used a dual task design where listeners were required to perform a task with varying attentional demands (‘High Demand’ vs. ‘Low Demand’) on brief auditory (Experiment 1a) or visual (Experiment 1b) signals presented during the gap. Experiments 2 and 3 required participants to ignore distractor sounds and focus on the change detection task. Our results demonstrate that the maintenance of scene information in short-term memory is influenced by the availability of attentional and/or processing resources during the gap, and that this dependence appears to be modality specific. We also show that these processes are susceptible to bottom up driven distraction even in situations when the distractors are not novel, but occur on each trial. Change detection performance is systematically linked with the, independently determined, perceptual salience of the distractor sound. The findings also demonstrate that the present task may be a useful objective means for determining relative perceptual salience. Distraction is measured by presenting distractor stimuli during a scene gap. Scene maintenance in memory depends on availability of resources during the gap. This dependence appears to be modality specific. Scene maintenance also prone to bottom up distraction even when distractors not novel. Performance depends on the perceptual salience of the distractor sound.
