无关声音效应是记忆心理学家在研究语音回路的结构时所发现的无关声音刺激干扰系列回忆任务的现象。近年来对无关声音效应的研究已经出现很多,但是由于理论的侧重点和研究的方法学不同,对无关声音效应的解释仍然存在着不少疑义。目前对无关声音效应的解释主要有听觉强制加工说、状态改变假设说、记忆加工负荷说三种,而响度差异的研究至今还没有一个定论。 Irrelevant sound effects are the phenomenon of memory-psychologists’ interference with a series of recall tasks found in the study of the structure of the speech loop. In recent years, there have been many researches on unrelated sound effects. However, there are still many doubts about the explanation of unrelated sound effects because of the different emphasis of the theory and the methodology of the study. At present, the explanations of unrelated sound effects mainly include auditory processing, hypothesis of state change, memory processing load, and so on. However, there is still no conclusion about the study of loudness difference so far.
