A meta-analysis of 26 published articles (with 36 independent participant groups) was conducted to analyze the relationship between task-switching effects and aging. Latency served as the dependent measure. Multilevel modeling was used to test for additive and multiplicative complexity effects in local and global switch costs. Global task switching was found to add 1 or more stages to processing and resulted in a marked age deficit. Local task-switching costs, on the other hand, showed a multiplicative complexity effect but no specific attention-related age deficits. Cueing or switch predictability did not affect age differences.
对 26 篇已发表文章(涉及 36 个独立的参与者群体)进行了荟萃分析,以分析任务转换效应与衰老之间的关系。潜伏期为因变量。使用多层次模型来测试局部和全局转换成本中的附加和乘法复杂性效应。发现全局任务转换为处理过程增加了 1 个或更多阶段,导致明显的年龄缺陷。另一方面,局部任务转换成本表现出乘法复杂性效应,但没有特定的与注意力相关的年龄缺陷。线索或转换可预测性并不影响年龄差异。
