Abstract Use of Multinomial Processing Tree (MPT) models is illustrated by fitting one to data of Dhir (2017). Her experiment examined age and association type in a paired-associate recall task. Age and Pair-Type had interactive effects on probability of a correct response. A natural interpretation of the interaction would be that both factors impact the same mental process. However, fitting an MPT leads to the conclusion that Age and Pair-Type selectively influence two separate processes, one following the other. A possible interpretation of these is as attempts at specific (verbatim) retrieval and knowledge supported (gist) processing, selectively influenced by Age and Pair-Type, respectively. The order of these processes is not determined by the response probabilities. In a further section of the paper, we show that if response times or other measures had also been available, they could have resolved the process order, but might have left it undetermined. We give necessary and sufficient conditions for two factors to selectively influence two ordered vertices in an MPT, with either order of the vertices accounting for both response probability and response time. They do so if and only if the MPT is equivalent to a special processing tree, not necessarily an MPT itself.

从与年龄相关的记忆错误概率推断出的多项处理树：如果响应时间可用，推断更多的可能性

摘要 通过对 Dhir (2017) 的数据进行拟合来说明多项处理树 (MPT) 模型的使用。她的实验在配对关联回忆任务中检查了年龄和关联类型。年龄和配对类型对正确响应的概率具有交互作用。对相互作用的自然解释是这两个因素影响相同的心理过程。然而，拟合 MPT 得出的结论是 Age 和 Pair-Type 选择性地影响两个独立的过程，一个跟随另一个。对这些的可能解释是尝试进行特定（逐字）检索和知识支持（要点）处理，分别受年龄和配对类型的选择性影响。这些过程的顺序不是由响应概率决定的。在论文的另一部分，我们表明，如果响应时间或其他措施也可用，他们可以解决流程订单，但可能无法确定。我们给出了两个因素有选择地影响 MPT 中两个有序顶点的充分必要条件，顶点的任一顺序都考虑了响应概率和响应时间。当且仅当 MPT 相当于一个特殊的处理树，而不一定是 MPT 本身时，他们才会这样做。
