Our experiments were aimed at determining if the delayed matching-to-sample paradigm (DMS) could be used to study short-term acoustic recognition memory in young children and whether or not differences exist between children and adults. Our results indicate that the DMS paradigm can produce reliable data in young children. The decay of acoustic information over time was equivalent in both children and adults, beginning at about 1 s and lasting for longer than 10 s. With 7-element acoustic frequency-pattern sequences, a performance difference between children and adults was observed which appears explicable on the basis of longer memory spans in the adult subjects. When we equated for span length, this effect was no longer apparent.
我们的实验旨在确定延迟样本匹配范式（DMS）是否可用于研究幼儿的短期听觉识别记忆，以及儿童与成人之间是否存在差异。我们的结果表明，DMS范式能够在幼儿中产生可靠的数据。声音信息随时间的衰减在儿童和成人中是相同的，大约从1秒开始，持续超过10秒。对于7元素的声频模式序列，观察到儿童与成人之间存在表现差异，这似乎可以基于成人受试者更长的记忆跨度来解释。当我们使跨度长度相等时，这种效应不再明显。
