The list length effect in recognition memory refers to the finding that recognition performance for a short list is superior to that for a long list. The list length effect is consistent with the predictions of item noise models, but context noise models predict no effect. Recently, it has been argued that if potential confounds are controlled, the list length effect is eliminated. We report the results of two experiments in which we looked at the role of attention and the remember-know task in the detection of the list length effect. We conclude that there is no list length effect when potential confounds are controlled and that it is the design used to control for attention that is most vital.
在再认记忆中，列表长度效应是指对短列表的识别表现优于对长列表的识别表现。列表长度效应与项目噪声模型的预测一致，但上下文噪声模型预测没有影响。最近，有人认为，如果控制潜在的混淆因素，列表长度效应就会消除。我们报告了两项实验的结果，在这些实验中，我们研究了注意和“记得-知道”任务在检测列表长度效应中的作用。我们的结论是，当控制潜在的混淆因素时，不存在列表长度效应，而且对注意力进行控制的设计是最重要的。
