A paradigm for the determination of time-accuracy functions (TAFs) for individual participants is introduced for two pairs of tasks differing in cognitive complexity, that is, word scanning vs cued recognition and figural scanning vs figural reasoning. TAFs can be used to test dissociations of cognitive processes beyond scale-related ambiguities of ordinal interactions. The approach is applied to examine the cognitive-aging hypothesis that a single slowing factor can account for interactions between adult age and cognitive task complexity. Twenty young and 20 old adults participated in 17 sessions. Presentation times required for 75, 87.5, and 100% accuracies were determined for each task with a variant of the psychophysical method of limits. Accuracy was fit by negatively accelerated functions of presentation time. State-trace analyses showed that different slowing factors are required for high- and low-complexity tasks. Relations to speed-accuracy and performance-resource functions are discussed.

用于确定过程和人员差异的时间精度函数：认知老化的应用

针对两对认知复杂性不同的任务，即单词扫描与线索识别以及图形扫描与图形推理，引入了确定个体参与者时间精度函数 (TAF) 的范式。TAF 可用于测试认知过程的分离，超越与尺度相关的有序交互的模糊性。该方法用于检验认知老化假设，即单个减缓因素可以解释成年年龄和认知任务复杂性之间的相互作用。20 名年轻人和 20 名老年人参加了 17 次会议。75%、87.5% 和 100% 准确度所需的演示时间是通过心理物理学极限方法的变体为每项任务确定的。准确性由呈现时间的负加速函数拟合。状态跟踪分析表明，高复杂度和低复杂度的任务需要不同的减缓因素。讨论了速度精度和性能资源函数的关系。
