在正常的衰老过程中，联想记忆的衰退比单个项目的记忆更严重。单位化是一个编码过程，定义为创建一个新的单一实体来表示一个新的任意关联。目前的研究测试的假设，年龄相关的差异，在联想记忆可以减少以下编码指令，促进单位化。在两个实验中，20名年轻人和20名老年人组成的小组在两种情况下学习单词和背景颜色之间的新联系。在项目细节条件下，他们必须想象项目与背景的颜色相同;这是一个促进关联单位化的指令。在上下文细节条件下，这并没有促进单位化，他们必须想象该项目与另一个彩色对象相互作用。在测试中，他们必须检索与每个单词相关的颜色（源记忆）。在这两个实验中，结果表明，在上下文细节，但不是在项目细节条件下的源记忆性能的年龄相关的递减。此外，实验2研究了老年受试者的接收器操作特性，并表明熟悉度对项目细节中的源记忆表现的贡献大于背景细节条件。这些研究结果表明，新的协会单位化可以克服在老化中观察到的联想记忆缺陷，至少对于项目颜色协会。
In normal aging, memory for associations declines more than memory for individual items. Unitization is an encoding process defined by creation of a new single entity to represent a new arbitrary association. The current study tested the hypothesis that age-related differences in associative memory can be reduced following encoding instructions that promote unitization. In two experiments, groups of 20 young and 20 older participants learned new associations between a word and a background color under two conditions. In the item detail condition, they had to imagine that the item is the same color as the background; an instruction promoting unitization of the associations. In the context detail condition, that did not promote unitization, they had to imagine that the item interacted with another colored object. At test, they had to retrieve the color that was associated to each word (source memory). In both experiments, the results showed an age-related decrement in source memory performance in the context detail but not in the item detail condition. Moreover, Experiment 2 examined receiver operating characteristics in older participants and indicated that familiarity contributed more to source memory performance in the item detail than in the context detail condition. These findings suggest that unitization of new associations can overcome the associative memory deficit observed in aging, at least for item-color associations.
