尽管基于互联网的实验越来越受欢迎，但大多数研究依赖于直接评估参与者的反应，而不是反应时间。在本文中，我们提出了两个实验，证明了使用webexp（一种设计用于在互联网上运行心理学实验的软件包）在万维网上收集响应延迟数据的可行性。实验1使用WebExp收集已知时间间隔的测量值（使用键盘重复生成）。由此得出的测量结果在平台和负载条件下都是准确的。在实验2中，我们使用WebExp从心理语言学文献中复制了一个基于实验室的自定节奏阅读研究。基于web的复制数据与原始研究的数据显著相关，并显示出相同的主要效应和相互作用。我们得出的结论是，WebExp可以用于获得可靠的响应时间数据，至少对于自定节奏阅读范例来说是这样。
Although Internet-based experiments are gaining in popularity, most studies rely on directly evaluating participants' responses rather than response times. In the present article, we present two experiments that demonstrate the feasibility of collecting response latency data over the World-Wide Web using WebExp-a software package designed to run psychological experiments over the Internet. Experiment I uses WebExp to collect measurements for known time intervals (generated using keyboard repetition). The resulting measurements are found to be accurate across platforms and load conditions. In Experiment 2, we use WebExp to replicate a lab-based self-paced reading study from the psycholinguistic literature. The data of the Web-based replication correlate significantly with those of the original study and show the same main effects and interactions. We conclude that WebExp can be used to obtain reliable response time data, at least for the self-paced reading paradigm.
