Source memory for truth is usually better than for falsity, and similar effects are observed for important compared with unimportant information. A recently found interaction between information veracity and importance indicates that people effectively prioritize encoding true information (but not false). Yet it is unclear whether the feedback about veracity and importance of the information is integrated into joint memory representation. In the following experiment, we investigated whether source memory for veracity and importance dimensions is stochastically dependent. Students (N = 82) memorized trivia statements along with their veracity and importance status, which resulted in four different combinations of sources ("true and important", "true and unimportant", "false and important", "false and unimportant"). The analysis with a multidimensional source memory multinomial model revealed that the joint retrieval of "true" and "important" feedback as compound information is better than for all other combinations. Moreover, the veracity dimension was memorized better than the importance dimension, showing that we remember whether information is true or false better than whether it is important or unimportant.
对真实信息的源记忆通常比对虚假信息的源记忆更好，并且与不重要的信息相比，对重要信息也观察到类似的效果。最近发现的信息准确性和重要性之间的相互作用表明，人们有效地优先编码真实信息（而非虚假信息）。然而，尚不清楚关于信息准确性和重要性的反馈是否会整合到联合记忆表征中。在接下来的实验中，我们研究了准确性和重要性维度的源记忆是否存在随机依赖性。学生（N = 82）记忆琐事陈述以及它们的准确性和重要性状态，这产生了四种不同的源组合（“真实且重要”、“真实且不重要”、“虚假且重要”、“虚假且不重要”）。使用多维源记忆多项式模型进行的分析表明，作为复合信息的“真实”和“重要”反馈的联合检索比所有其他组合都更好。此外，准确性维度的记忆比重要性维度更好，这表明我们记住信息是真是假比记住它是否重要更好。
