对复杂事件的完整记忆不仅需要对特定特征(如物品、位置、颜色、大小)的记忆，还需要将这些特征绑定在一起的完整认知过程。绑定提供了某些功能属于一起的纪念体验。这里提出的实验旨在解释这些是复杂记忆中与年龄相关的变化的潜在可分离来源-即，调查复杂事件的与年龄相关的记忆变化是否可能源于(1)组成复杂记忆的信息的记忆类型的记忆缺陷，(2)将这些信息绑定到复杂记忆中所需的过程，或(3)这两个组成部分都有缺陷。年轻人和老年人被呈现在一个阵列中的彩色物品。与年轻人相比，老年人在对位置的识别记忆方面存在特定和不成比例的缺陷，但对物品或颜色的识别记忆没有。此外，老年人对绑定信息的识别记忆一直较差，特别是当所有特征都是故意获得的时候。这些特征和绑定缺陷分别导致了被描述为老年人的背景和源记忆障碍。
Intact memory for complex events requires not only memory for particular features (e.g., item, location, color, size), but also intact cognitive processes for binding the features together. Binding provides the memorial experience that certain features belong together. The experiments presented here were designed to explicate these as potentially separable sources of age-associated changes in complex memory-namely, to investigate the possibility that age-related changes in memory for complex events arise from deficits in (1) memory for the kinds of information that comprise complex memories, (2) the processes necessary for binding this information into complex memories, or (3) both of these components. Young and older adults were presented with colored items located within an array. Relative to young adults, older adults had a specific and disproportionate deficit in recognition memory for location, but not for item or for color. Also, older adults consistently demonstrated poorer recognition memory for bound information, especially when all features were acquired intentionally. These feature and binding deficits separately contribute to what have been described as older adults' context and source memory impairments.
