Response time information has recently attracted significant attention in the literature as it may provide meaningful information about item preknowledge. The methods that use response time information to identify examinees with potential item preknowledge make an implicit assumption that the examinees with item preknowledge differ in their response time patterns when compared to examinees without item preknowledge. This study uses a multiple-group extension of van der Linden's Lognormal Response Time Model with a gated mechanism to quantify the differences in latent speed between examinees with and without item preknowledge when responding to compromised and uncompromised items. Our findings indicate that there may be a wide range for potential effect of item preknowledge on response time. The effect of item preknowledge on response times is likely to be contextual and depends on many factors such as characteristics of test-takers, the nature of item preknowledge, and item characteristics. We recommend that researchers systematically quantify the effect sizes in their studies, and if possible, manipulate the effect size for a wide range while studying the effectiveness of already existing or new methods to detect examinees with item preknowledge through simulation.

项目预知对响应时间的影响:使用带门控机制的多组对数正态响应时间模型分析两个数据集

响应时间信息最近在文献中引起了极大的关注,因为它可以提供有关项目预知识的有意义的信息。使用响应时间信息来识别具有潜在项目预知的考生的方法隐含假设,与没有项目预知的考生相比,具有项目预知的考生的响应时间模式不同。本研究使用范德林登的对数正态响应时间模型的多组扩展和门控机制来量化考生在响应受损和未受损项目时有和没有项目预知的潜在速度差异。我们的研究结果表明,项目预知对响应时间的潜在影响可能范围很广。项目预知对响应时间的影响可能与上下文有关,并取决于许多因素,例如应试者的特征、项目预知的性质和项目特征。我们建议研究人员在他们的研究中系统地量化效应大小,如果可能,在研究现有或新方法的有效性时,在更大范围内操纵效应大小,以通过模拟检测具有项目预知的考生。
