当额外的项目背景从一个研究到另一个测试发生变化时，思考以前研究过的项目的能力往往会受到损害。在一系列的五个实验中，这种损害是以一种稍微不同的方式诱导的。一个片段（如ri-rop）的一个刚刚学习的字（雨滴）被证明是不容易完成，如果它是一位一位（r--p，r-rp，ri--rp，ri--rop），而不是一次全部（实验1，3，4和5）。没有这样的效果被发现，如果这个词没有事先研究（实验2，3，4和5）。这种模式的结果发生，即使片段的研究和nonstudied的话出现在同一个测试中，并在受试者不能告诉是否一个给定的片段是一个研究或nonstudied的话（实验4和5）。此外，对于事先已经研究过的话，减值被证明是增加系统的步骤数参与呈现的单词片段（实验3），也坚持当完成的最终版本的片段所允许的时间从4秒增加到一个完整的分钟（实验5）。
The ability to think of a previously studied item has often been shown to be impaired when, in one way or another, the extraitem context is changed from study to test. In a series of five experiments, such impairment is induced in a somewhat different way. A fragment (eg ri--rop) of a just-studied word (raindrop) is shown to be less readily completed if it is presented bit by bit (r------p, r----rp, ri--rp, ri--rop) rather than all at once (Experiments 1, 3, 4, and 5). No such effect is found if the word has not been studied beforehand (Experiments 2, 3, 4, and 5). This pattern of results occurs even when fragments of studied and nonstudied words occur in the same test and under conditions in which subjects cannot tell whether a given fragment is of a studied or nonstudied word (Experiments 4 and 5). In addition, for words that have been studied beforehand, the impairment is shown to increase systematically with the number of steps involved in the presentation of the word fragment (Experiment 3) and also to persist when the time allowed for completion of the final version of the fragment is increased from 4 s to a full minute (Experiment 5).
