The effect of face covering masks on listeners' recall of spoken sentences was investigated. Thirty-two German native listeners watched video recordings of a native speaker producing German sentences with and without a face mask, and then completed a cued-recall task. Listeners recalled significantly fewer words when the sentences had been spoken with a face mask. This might suggest that face masks increase processing demands, which in turn leaves fewer resources for encoding speech in memory. The result is also informative for policy-makers during the COVID-19 pandemic, regarding the impact of face masks on oral communication.

口罩对口语句子回忆的影响

研究了面罩对听众口语回忆的影响。三十二名德国本地听众观看了一位母语人士的视频录像，该视频在有或没有口罩的情况下产生德语句子，然后完成了提示式召回任务。当用口罩说出句子时，听众回想的词明显少得多。这可能表明，口罩会增加处理需求，从而减少内存中用于编码语音的资源。该结果对于COVID-19大流行期间的决策者也很有帮助，涉及面罩对口头交流的影响。
