两个实验研究外来语音和非语音噪声对年轻人和老年人的视觉短期记忆任务的影响。实验1证实了一个早期的报告，即播放与任务无关的语音对老年人的干扰并不比年轻人多（Rouleau &贝尔维尔，1996），表明在竞争性语音存在的情况下，短期记忆中的“不相关声音效果”以不同的方式回忆目标（Tun，O'Kane，&温菲尔德，2002）。实验2将这一结果扩展到非言语噪声，并表明该结果不能归因于老年组中的听力困难，尽管数据还显示，老年人认为噪音比年轻人更不烦人和不舒服。无关的声音效果的理论，和认知老化的影响，进行了讨论。
Two experiments examine the effects of extraneous speech and nonspeech noise on a visual short-term memory task administered to younger and older adults. Experiment 1 confirms an earlier report that playing task-irrelevant speech is no more distracting for older adults than for younger adults (Rouleau & Belleville, 1996), indicating that "irrelevant sound effects" in short-term memory operate in a different manner to recalling targets in the presence of competing speech (Tun, O'Kane, & Wingfield, 2002). Experiment 2 extends this result to nonspeech noise and demonstrates that the result cannot be ascribed to hearing difficulties amongst the older age group, although the data also show that older adults rated the noise as less annoying and uncomfortable than younger adults. Implications for theories of the irrelevant sound effect, and for cognitive ageing, are discussed.
