这项研究着眼于需要多少输入来获得足够的重复前9,000个英语单词的学习发生。它使用各种大小和组成的语料库，看看需要多少输入标记才能获得至少12次重复，并满足9个1000个单词家族级别中的8个级别的大多数单词。略低于200，000个标记和300万个标记的语料库大小分别在第二个1，000字水平和第九个1，000字水平提供平均至少12次重复。就小说而言，这相当于2到25部小说（每部小说12万个代币）。考虑到每年大约1,000个单词家族的学习速度，这些输入量是可控的。已创建了免费提供的“中频阅读器”，以提供所需的适当类型的输入。
This study looks at how much input is needed to gain enough repetition of the 1st 9,000 words of English for learning to occur. It uses corpora of various sizes and composition to see how many tokens of input would be needed to gain at least twelve repetitions and to meet most of the words at eight of the nine 1000 word family levels. Corpus sizes of just under 200,000 tokens and 3 million tokens provide an average of at least 12 repetitions at the 2nd 1,000 word level and the 9th 1,000 word level respectively. In terms of novels, this equates to two to twenty-five novels (at 120,000 tokens per novel). Allowing for learning rates of around 1,000 word families a year, these are manageable amounts of input. Freely available "Mid-frequency Readers" have been created to provide the suitable kind of input needed.
