被忽视的听觉序列对短时记忆的干扰（变态效应）常被描述为偏离事件的注意捕获（偏离效应）。然而，本研究表明，改变状态和偏离效应是听觉干扰的功能不同形式：改变状态的语音对视觉-言语序列回忆的干扰与语音中嵌入的单个偏离语音的影响无关（实验1）;在缺失项目任务中，发现了语音偏离效应，但没有发现改变状态效应（实验2）;和一个异常的语音重复的背景下，交替的语音无关的语音序列中断串行回忆（实验3）。作者的结论是，改变状态的效果是一个冲突的结果，同时适用于相关和不相关的材料，而偏差效应反映了一个更一般的注意力捕获过程。
The disruption of short-term memory by to-be-ignored auditory sequences (the changing-state effect) has often been characterized as attentional capture by deviant events (deviation effect). However, the present study demonstrates that changing-state and deviation effects are functionally distinct forms of auditory distraction: The disruption of visual-verbal serial recall by changing-state speech was independent of the effect of a single deviant voice embedded within the speech (Experiment 1); a voice-deviation effect, but not a changing-state effect, was found on a missing-item task (Experiment 2); and a deviant voice repetition within the context of an alternating-voice irrelevant speech sequence disrupted serial recall (Experiment 3). The authors conclude that the changing-state effect is the result of a conflict between 2 seriation processes being applied concurrently to relevant and irrelevant material, whereas the deviation effect reflects a more general attention-capture process.
