In three experiments we investigated cryptomnesia (unconscious plagiarism) and source memory using a word-search puzzle task. Subjects first alternated with a "computer partner" in locating words from 4 puzzles. They then attempted to recall their previously generated items as well as to locate additional new words. Substantially more plagiarism was committed in these tasks than was observed in a study by A. S. Brown and D. R. Murphy (1989), in which Ss generated category exemplars. Manipulations of retention interval (Experiment 1) and degree of encoding (Experiments 2a and 2b) reliably influenced plagiarism rates. Source confusions from a modified recognition memory task (Experiment 3) were used as the basis for a unitary relative strength model to explain both source and occurrence (item) forgetting.
在三项实验中，我们使用单词搜索谜题任务研究了潜隐记忆（无意识抄袭）和源记忆。受试者首先与“计算机伙伴”交替从4个谜题中找出单词。然后，他们试图回忆自己之前生成的项目，并找出更多新单词。与A.S.布朗和D.R.墨菲（1989年）的一项研究相比，这些任务中的抄袭行为要多得多，在该研究中，受试者生成类别范例。对保持间隔（实验1）和编码程度（实验2a和2b）的操纵可靠地影响了抄袭率。来自修改后的识别记忆任务（实验3）的源混淆被用作一个统一相对强度模型的基础，以解释源遗忘和出现（项目）遗忘。
