提取任务对联合效应和特征效应的调节不具有测验范式敏感性

The Modulation of Retrieval Tasks on Conjunction Effect and Feature Effect in Faces is Insensitive to Test Paradigm

我们近期发表的研究显示,联合效应和特征效应具有提取任务敏感性,表现为来源提取较项目再认任务的相应效应更强。然而,来源提取任务中仅采用了排除范式,其他测验范式的相应效应尚未报告。因此本实验在此基础上更改了测验范式,采用三键范式。结果显示,来源提取任务中的联合效应和特征效应仍然比再认任务中的相应效应强,表明联合效应和特征效应的提取任务敏感性不为测验范式所调节,提取任务对两类效应的调节与双重加工模型相吻合。

One of our recent studies has shown that both item recognition and source retrieval can elicit a robust conjunction effect and feature effect for faces,but they are both larger in the source retrieval task. However,these findings are found by adopting only the exclusion paradigm. Whether the same patterns can be observed under other paradigms is unclear. To solve this problem,this research adopted three-key paradigm rather than the exclusion paradigm for further study. The results showed that both the conjunction effect and the feature effect were still much larger in the source retrieval task than in the item recognition task. These results strongly demonstrate that both conjunction effect and feature effect are sensitive to retrieval tasks,but not to the test paradigm; such regulation of retrieval tasks on these two effects is consistent with the dualprocess model.
