如果动作是在受试者执行的任务(SPT)中执行的，那么对动作短语的记忆比只在言语任务(VT)中听的要好。这种效应归因于SPTS比VTS更好的特定项目编码。项目间关系信息的作用是有争议的，分类结构列表的聚类结果也不一致(见Engelkamp，1998)。本研究通过证明有意关系编码在VTS中的使用比在SPTS中更有效，并影响聚集的程度，从而有助于阐明这些效应。如果列表结构不明显，通过在列表呈现之前呈现类别标签并要求受试者使用该前信息来诱导有意编码会增加VTS中的聚集性而不是SPTS中的聚集性。在没有前置信息的情况下，VTS和SPTS的聚类分没有差异；有前置信息时，VTS的聚类性强于SPTS。作者建议如何解释关于集群效应的不一致发现。
Memory for action phrases is better if the actions are enacted in subject-performed tasks (SPTs) than if they are only listened to in verbal tasks (VTs). This effect is ascribed to better item-specific encoding of SPTs than of VTs. The role of interitem relational information is controversial, and the findings of clustering with categorically structured lists are inconsistent (see Engelkamp, 1998). The present study contributes to clarifying these effects by demonstrating that intentional relational encoding can be used more efficiently in VTs than in SPTs and influences the degree of clustering. If the list structure is not obvious, inducing intentional encoding by presenting the category labels prior to list presentation and asking subjects to use this preinformation increases clustering in VTs but not in SPTs. Without preinformation, clustering scores of VTs and SPTs did not differ; with preinformation, clustering of VTs was stronger than that of SPTs. The authors suggest how the inconsistent findings with regard to clustering effects can be explained.
