The self-generation effect refers to the finding that people’s memory for information tends to be better when they generate it themselves. Counterintuitively, when proofreading, this effect may make it more difficult to detect mistakes in one’s own writing than in others’ writing. We investigated the self-generation effect and sources of individual differences in proofreading performance in two eye-tracking experiments. Experiment 1 failed to reveal a self-generation effect. Experiment 2 used a studying manipulation to induce overfamiliarity for self-generated text, revealing a weak but non-significant self-generation effect. Overall, word errors (i.e., wrong words) were detected less often than non-word errors (i.e., misspellings), and function word errors were detected less often than content word errors. Fluid intelligence predicted proofreading performance, whereas reading comprehension, working memory capacity, processing speed, and indicators of miserly cognitive processing did not. Students who made more text fixations and spent more time proofreading detected more errors.

自发电效应指的是发现当人们自己生成信息时，人们对信息的记忆往往会更好。与直觉相反，在校对时，这种效果可能会使发现自己写作中的错误比他人写作中的错误更难。我们在两个眼动追踪实验中研究了自我生成效应和校对性能个体差异的来源。实验 1 未能揭示自发电效应。实验 2 使用学习操作来诱导对自生成文本的过度熟悉，揭示了微弱但不显着的自生成效果。总的来说，单词错误（即错误的单词）比非单词错误（即拼写错误）更少被检测到，功能词错误比实词错误更少被检测到。流体智能预测校对性能，而阅读理解、工作记忆容量、处理速度和吝啬认知处理指标则没有。进行更多文本注视并花费更多时间校对的学生发现了更多错误。
