根据来源猜测的概率匹配解释（Spanwald & Bayen，Journal of Experimental Psychology：Learning，Memory，and Cognition 28：631-651，2002），当人们在来源监控任务中不记得项目的来源时，他们将来源猜测概率与来源和项目类型之间的感知偶然性相匹配。在源监测实验中，两个源中的每一个所呈现的项目的一半与关于该源的示意性期望一致，而项目的另一半与关于另一源的示意性期望一致。参与者的源图式在编码时或在源监控测试之前被激活。测试结束后，受试者判断项目类型和来源的偶然性。通过β-多项式处理树建模获得源猜测的个体参数估计（β-MPT; Smith & Batchelder，Journal of Mathematical Psychology 54：167-183，2010）。我们发现，感知的偶然性和来源猜测之间的显着相关性，以及猜测偏差从真实的偶然性和来源记忆之间的相关性时，被试没有收到的图式信息，直到检索。这些发现支持概率匹配的帐户。
According to the probability-matching account of source guessing (Spaniol & Bayen, Journal of Experimental Psychology: Learning, Memory, and Cognition 28:631-651, 2002), when people do not remember the source of an item in a source-monitoring task, they match the source-guessing probabilities to the perceived contingencies between sources and item types. In a source-monitoring experiment, half of the items presented by each of two sources were consistent with schematic expectations about this source, whereas the other half of the items were consistent with schematic expectations about the other source. Participants' source schemas were activated either at the time of encoding or just before the source-monitoring test. After test, the participants judged the contingency of the item type and source. Individual parameter estimates of source guessing were obtained via beta-multinomial processing tree modeling (beta-MPT; Smith & Batchelder, Journal of Mathematical Psychology 54:167-183, 2010). We found a significant correlation between the perceived contingency and source guessing, as well as a correlation between the deviation of the guessing bias from the true contingency and source memory when participants did not receive the schema information until retrieval. These findings support the probability-matching account.
