In his comment on Heck and Erdfelder (2016, Psychonomic Bulletin & Review, 23, 1440-1465), Starns (2018, Psychonomic Bulletin & Review, 25, 2406-2416) focuses on the response time-extended two-high-threshold (2HT-RT) model for yes-no recognition tasks, a specific example for the general class of response time-extended multinomial processing tree models (MPT-RTs) we proposed. He argues that the 2HT-RT model cannot accommodate the speed-accuracy trade-off, a key mechanism in speeded recognition tasks. As a remedy, he proposes a specific discrete-state model for recognition memory that assumes a race mechanism for detection and guessing. In this reply, we clarify our motivation for using the 2HT-RT model as an example and highlight the importance and benefits of MPT-RTs as a flexible class of general-purpose, simple-to-use models. By binning RTs into discrete categories, the MPT-RT approach facilitates the joint modeling of discrete responses and response times in a variety of psychological paradigms. In fact, many paradigms either lack a clear-cut accuracy criterion or show performance levels at ceiling, making corrections for incautious responding redundant. Moreover, we show that some forms of speed-accuracy trade-off can in fact not only be accommodated but also be measured by appropriately designed MPT-RTs.
在他对 Heck 和 Erdfelder（2016，《心理通报与评论》，23，1440-1465）的评论中，Starns（2018，《心理通报与评论》，25，2406-2416）关注了用于 yes-no 识别任务的扩展反应时-双高阈限（2HT-RT）模型，这是我们提出的广义扩展反应时多项式处理树模型（MPT-RTs）的一个具体示例。他认为，2HT-RT 模型不能容纳速度-准确性权衡，这是速度识别任务中的一个关键机制。作为补救措施，他提出了一种特定的识别记忆离散状态模型，该模型假设检测和猜测的竞争机制。在本回复中，我们澄清了使用 2HT-RT 模型作为示例的动机，并强调了 MPT-RTs 作为一种灵活的通用、易于使用的模型类的重要性和优势。通过将 RT 分为离散类别，MPT-RT 方法促进了各种心理范式中离散响应和反应时间的联合建模。事实上，许多范式要么缺乏明确的准确性标准，要么表现出接近上限的水平，因此对轻率反应的校正变得多余。此外，我们表明，某些形式的速度-准确性权衡实际上不仅可以被容纳，而且可以通过适当设计的 MPT-RTs 进行测量。
