通过比较匹配组的老年人和年轻人在文本识别任务中的表现，研究了老年人话语记忆。实验对象听了一段口头文本，然后被要求检测文本的书面版本的变化。在文本的相关部分被呈现之前，材料的延迟和数量被操纵。结果表明，话语记忆通常会随着年龄的增长而受损。延迟对记忆的影响表现出年龄差异。对措辞的记忆（检测非语义变化的能力）在两个年龄组中都迅速下降。虽然年轻人表现出良好的意义保留（在10秒延迟时，语义变化的检测正确率为98%，在40秒延迟时，正确率为88%），但老年人对语义信息的保留很差（在10秒延迟时，语义变化的检测率从83%下降到40秒延迟时的33%）。不同类型语义变化的表现比较表明，旧的，但没有…
Memory for discourse in old age was examined by comparing the performance of matched groups of old and young subjects in a text recognition task. Subjects listened to a spoken text, and were then required to detect changes in a written version of the text. The delay and amount of material intervening before the relevant portion of the text was re‐presented, were manipulated. The results showed that memory for discourse is generally impaired by aging. The effects of delay showed age differences in retention. Memory for wording (ability to detect non‐semantic changes) declined rapidly in both age groups. While the young showed good retention of meaning (detection of semantic changes was 98 percent correct at 10 seconds delay and 88 percent correct at 40 seconds), semantic information was poorly retained by the old group (detection of semantic Changes fell from 83 percent at 10 seconds to 33 percent at 40 seconds). Comparison of performace across different types of semantic change showed that the old, but no...
