通过对 33 项研究（48 个独立参与者组）的荟萃分析（使用潜伏期作为依赖测量值）和 30 项研究（40 个独立参与者组）重点关注准确性，研究了双任务效应与衰老之间的关系。推导出布林利图和状态迹，并开发了一个模型来解释不同类型的复杂性（加法和乘法）。双任务处理对延迟的影响是累加性的，这种累加成本在老年人中比在年轻人中更大，并且比总体放缓的预测更大。该成本很小并且与任务复杂性无关。双任务处理对 Logit 转换准确性的影响同样是累加的，但没有特定的年龄缺陷与这种双任务成本相关。
The relations between dual-task effects and aging were examined through a meta-analysis of 33 studies (with 48 independent participant groups) using latency as the dependent measure and 30 studies (with 40 independent participant groups) focusing on accuracy. Brinley plots and state traces were derived, and a model to explicate different types of complexity (additive and multiplicative) was developed. The effects of dual-task processing on latency were additive, and this additive cost was larger in older adults than in younger adults and larger than predicted from general slowing. This cost was small and independent of task complexity. The effects of dual-task processing on logit-transformed accuracy were likewise additive, but no specific age deficit was associated with this dual-task cost.
