Sixty subjects, 30 young and 30 old, were treated for word recognition using a controlled-lag method. A significant age differences was found for both recognition and for a subsequent recall task. Young subjects were superior to old on both recognition and recall. The greater the lag between the two presentations of a word, the greater the number of errors for both age groups. Most errors were made towards the beginning of the list, with a sharp drop in the middle, and a slight increase in the end. The older people took more time to complete the recognition task than the young.
60名受试者，30名年轻人和30名老年人，采用控制延迟法进行单词识别治疗。在识别和随后的回忆任务中均发现了显著的年龄差异。年轻受试者在识别和回忆方面均优于老年受试者。单词两次呈现之间的延迟越大，两个年龄组的错误数量就越多。大多数错误出现在列表开头，中间急剧下降，结尾略有增加。老年人完成识别任务比年轻人花费更多时间。
