The temporal contiguity effect is the tendency to form associations between items presented in nearby study positions. In the present study, we explored whether temporal contiguity predicted conversion to cognitively unimpaired‐declining (CUD) status from a baseline of unimpaired older adults. Data from 419 participants were drawn from the Wisconsin Registry of Alzheimer’s Prevention (WRAP) data set and analysed with binary logistic regressions. Temporal contiguity was calculated using the Rey Auditory Verbal Learning Test. Other predictors included age, years of education, sex, APOE‐ε4 status, and other measures of memory recall. Lower temporal contiguity predicted conversion to CUD after accounting for covariates. These findings support the hypothesis that temporal organization in memory is related to cognitive decline and suggest that temporal contiguity may be used for studies of early detection.

时间连续性和衰老：记忆组织在认知衰退中的作用

时间邻近效应是在附近研究位置呈现的项目之间形成关联的趋势。在本研究中，我们探讨了时间连续性是否可以预测从未受损老年人的基线向认知未受损下降（CUD）状态的转变。419 名参与者的数据取自威斯康星州阿尔茨海默病预防登记处 (WRAP) 数据集，并使用二元逻辑回归进行分析。使用雷伊听觉言语学习测试计算时间连续性。其他预测因素包括年龄、受教育年限、性别、APOE-ε4状态和其他记忆回忆指标。考虑协变量后，较低的时间连续性可预测转换为 CUD。这些发现支持了这样的假设：记忆中的时间组织与认知能力下降有关，并表明时间连续性可用于早期检测的研究。
