Research on the perception of temporal order uses either temporal-order judgment (TOJ) tasks or synchrony judgment (SJ) tasks, in both of which two stimuli are presented with some temporal delay and observers must judge the order of presentation. Results generally differ across tasks, raising concerns about whether they measure the same processes. We present a model including sensory and decisional parameters that places these tasks in a common framework that allows studying their implications on observed performance. TOJ tasks imply specific decisional components that explain the discrepancy of results obtained with TOJ and SJ tasks. The model is also tested against published data on audiovisual temporal-order judgments, and the fit is satisfactory, although model parameters are more accurately estimated with SJ tasks. Measures of latent point of subjective simultaneity and latent sensitivity are defined that are invariant across tasks by isolating the sensory parameters governing observed performance, whereas decisional parameters vary across tasks and account for observed differences across them. Our analyses concur with other evidence advising against the use of TOJ tasks in research on perception of temporal order.
研究时间顺序感知既可以使用时间顺序判断（TOJ）任务，也可以使用同步判断（SJ）任务，在这两种任务中，两个刺激会以一定的时间延迟呈现，观察者必须判断呈现的顺序。结果通常因任务而异，这引发了人们对它们是否测量相同过程的担忧。我们提出了一个包含感觉和决策参数的模型，将这些任务置于一个共同的框架中，以便研究它们对观察到的性能的影响。TOJ 任务暗示了特定的决策成分，这些成分解释了在 TOJ 和 SJ 任务中获得的结果差异。该模型还针对视听时间顺序判断的已发表数据进行了测试，拟合效果令人满意，尽管 SJ 任务可以更准确地估计模型参数。定义了潜在主观同时性和潜在敏感性的度量，这些度量通过隔离控制观察到的性能的感觉参数在任务之间保持不变，而决策参数则因任务而异，并解释了它们之间的观察到的差异。我们的分析与其他建议不要在时间顺序感知研究中使用 TOJ 任务的证据一致。
