Processing speed (PS) is an important indicator of cognitive functioning and normal aging. However, the tools used to evaluate these are often rather simplistic and only assess one cognitive component. The aim of this study was to use cognitive mobile games (CMG) to evaluate the evolution of reaction times over the life span during different cognitive tasks. We carried out a retrospective observational study in which we obtained anonymized results of 15,000 subjects. Scores of five CMG that train arithmetic, vocabulary, response control, visual attention and recognition, and working memory were analyzed. Overall, we observed a highly statistically significant decrease ( < 0.001) in PS and a decrease of accuracy ( < 0.001) with increasing participant age, indicating that for each cognitive function tested, older participants performed cognitive tasks more slowly than younger participants. We also observed an interaction between the age of the participants and the number of errors. These results are consistent with physiological data with respect to aging and cognition. Owing to their wide availability and ease of use, CMG could be used as a simple tool to monitor cognitive function such as PS. Further studies are needed to study the influence of pathologies on those variables.
处理速度（PS）是认知功能和正常衰老的一项重要指标。然而，用于评估这些的工具往往相当简单，且仅评估一个认知成分。本研究的目的是使用认知手机游戏（CMG）来评估在不同认知任务期间整个生命跨度内反应时间的变化。我们进行了一项回顾性观察研究，在该研究中我们获得了15000名受试者的匿名结果。分析了训练算术、词汇、反应控制、视觉注意力与识别以及工作记忆的五款CMG的得分。总体而言，我们观察到随着参与者年龄的增加，PS出现了高度统计学显著性下降（<0.001），准确性也出现了下降（<0.001），这表明对于所测试的每种认知功能，年长参与者执行认知任务的速度比年轻参与者更慢。我们还观察到参与者年龄与错误数量之间存在交互作用。这些结果与关于衰老和认知的生理数据一致。由于CMG广泛可得且易于使用，它可作为一种监测诸如PS等认知功能的简单工具。还需要进一步研究来探讨疾病对这些变量的影响。
