先前的研究表明，与年龄相关的变化检测下降可能是由于老年人使用了更保守的反应标准。然而，这一发现可能反映了传统变化检测设计的方法学局限性，在传统变化检测设计中，显示会持续呈现，直到检测到变化。在两个实验中，在变化检测版本中评估了成人年龄差异，该版本需要在每对变化前后显示后做出响应，从而减少响应标准的潜在贡献。老年人的表现比年轻人差，错误更大，需要更多的显示周期才能正确检测。在对基本知觉速度进行统计控制后，这些与年龄相关的表现下降显着减少。两个年龄组的搜索策略在很大程度上相似，但当需要更精确的变化空间定位时，感知速度在解释可检测性中与年龄相关的方差方面不太成功（实验 2）。因此，当前任务中老化的负面影响在于检测效率的降低，这主要是由于处理速度造成的，尽管一些策略级的影响也可能有所贡献。
Previous research has suggested that an age-related decline in change detection may be due to older adults using a more conservative response criterion. However, this finding may reflect methodological limitations of the traditional change detection design, in which displays are presented continuously until a change is detected. Across two experiments, adult age differences were assessed in a version of change detection that required a response after each pair of pre- and post-change displays, thus reducing the potential contribution of response criterion. Older adults performed worse than younger adults, with greater errors and requiring a greater number of display cycles for correct detection. These age-related performance declines were substantially reduced after controlling statistically for elementary perceptual speed. Search strategy was largely similar for the two age groups, but perceptual speed was less successful in accounting for age-related variance in detectability when a more precise spatial localization of change was required (Experiment 2). Thus, the negative effect of aging in the present tasks lies in a reduction of detection efficiency due largely to processing speed, though some strategy-level effects may also contribute.
