环境支持假说认为，通过在编码和/或提取阶段提供环境支持，可以减少老年人情景记忆的缺陷。为了检验这一假设的有效性，我们通过操纵数据驱动的过程来改变检索支持的量。年轻人和老年人进行了词干线索回忆任务的低数据驱动条件（LDDC），其中检索线索包括3个字母，和较高的数据驱动条件（HDDC），其中线索包括4个字母。老年人比年轻人从额外支持中受益更多。在LDDC条件下，老年人相对于年轻人表现出较大的缺陷，但在HDDC条件下没有发现年龄差异。这些研究结果表明，与年龄相关的记忆缺陷，可以减少通过增加环境支持检索与数据驱动的组成部分的检索处理。
The environmental support hypothesis postulates that it may be possible to reduce older adults' deficits in episodic memory by providing environmental support at the encoding and/or retrieval phases. To examine the validity of this hypothesis, we varied the amount of retrieval support by manipulating data-driven processes. Young and older adults performed a word-stem cued recall task under a low data-driven condition (LDDC) in which the retrieval cue comprised 3 letters, and a higher data-driven condition (HDDC) in which the cue comprised 4 letters. Older adults benefitted more than younger adults from the additional support. Older adults exhibited a large deficit relative to younger adults in the LDDC condition but no age differences were found in the HDDC condition. These findings demonstrate that age-related memory deficits can be reduced by increasing the environmental support at retrieval associated with the data-driven component of retrieval processing.
