使用个人计算机（PC）进行简单的视觉反应时间测试是有利的，因为硬件成本相对较低，用户熟悉，并且针对特定神经行为测试协议的软件开发相对容易。然而，通用计算机的设计并没有达到这种应用所需的毫秒级操作精度。不控制各种延迟来源的软件可能返回的反应时间值与真实的反应时间有很大的不同。我们已经开发并描述了一个免费的基于pc的简单视觉反应时间测试系统，类似于广泛使用的精神运动警戒任务（PVT）。此外，我们还集成了个性化的预测算法，用于近实时的神经行为表现预测。我们描述了系统作为一个整体在各种计算机硬件配置上测量反应时间的精度和准确性，并将其性能与“黄金标准”PVT-192设备进行了比较。我们表明，该系统能够测量反应时间，平均延迟小于10毫秒，误差范围与金标准相当。硬件选择的最关键方面是用于响应检测的鼠标类型，游戏鼠标比标准鼠标具有显著优势。该软件可从http://bhsai.org/downloads/pc-pvt/免费下载。
Using a personal computer (PC) for simple visual reaction time testing is advantageous because of the relatively low hardware cost, user familiarity, and the relative ease of software development for specific neurobehavioral testing protocols. However, general-purpose computers are not designed with the millisecond-level accuracy of operation required for such applications. Software that does not control for the various sources of delay may return reaction time values that are substantially different from the true reaction times. We have developed and characterized a freely available system for PC-based simple visual reaction time testing that is analogous to the widely used psychomotor vigilance task (PVT). In addition, we have integrated individualized prediction algorithms for near-real-time neurobehavioral performance prediction. We characterized the precision and accuracy with which the system as a whole measures reaction times on a wide range of computer hardware configurations, comparing its performance with that of the “gold standard” PVT-192 device. We showed that the system is capable of measuring reaction times with an average delay of less than 10 ms, a margin of error that is comparable to that of the gold standard. The most critical aspect of hardware selection is the type of mouse used for response detection, with gaming mice showing a significant advantage over standard ones. The software is free to download from http://bhsai.org/downloads/pc-pvt/.
