Short-term memory for sound content and sound localization was investigated in normal subjects using the same/different comparison of two sound stimuli separated by an interval. Auditory or visual interference tasks requiring recognition or spatial judgements were introduced in the interval. Auditory interference tasks reduced memory for sound content and sound location in a specific way. Memory for sound content was significantly more reduced by auditory recognition than by auditory spatial interference task. Visual interference tasks reduced significantly memory for sound location but not for sound content. These results suggest that (i) short-term memory for sound content and that for sound location involve partially distinct processing; and (ii) auditory spatial functions are more closely linked to visual functions than auditory recognition.
利用两个声音刺激之间的间隔进行相同/不同比较，对正常受试者的声音内容短期记忆和声音定位进行了研究。在间隔期间引入了需要识别或空间判断的听觉或视觉干扰任务。听觉干扰任务以特定方式降低了声音内容和声音位置的记忆。与听觉空间干扰任务相比，听觉识别对声音内容的记忆减少更为显著。视觉干扰任务显著降低了声音位置的记忆，但对声音内容的记忆没有影响。这些结果表明：（i）声音内容的短期记忆和声音位置的短期记忆涉及部分不同的处理过程；（ii）听觉空间功能与视觉功能的联系比听觉识别更紧密。
