The item-order hypothesis suggests that under certain conditions increased item processing can lead to deficits in order processing, and that this produces a dissociation in performance between item and order tasks. The generation effect is one such example. The word length effect is seen as another instance where this trade-off might be observed. The following experiments compare word length and generation effects under serial recall and single item recognition conditions. Short words are better recalled than long words on the serial recall task but long words were better recognised than short words. The results are consistent with the item-order approach and support a novel explanation for the word length effect.
项目-顺序假说认为，在某些条件下，项目加工的增加会导致顺序加工的缺陷，并且这会在项目任务和顺序任务的表现上产生分离。生成效应就是这样一个例子。词长效应被视为可能观察到这种权衡的另一个实例。以下实验比较了系列回忆和单项目识别条件下的词长效应和生成效应。在系列回忆任务中，短单词比长单词更容易被回忆起来，但在识别方面，长单词比短单词表现更好。这些结果与项目-顺序方法一致，并为词长效应提供了一种新的解释。
