对大样本单音节英语单词的主观频率估计从574名年轻人（本科生）和1590名不同年龄和教育背景的成年人中收集。后一组的估计数据是通过互联网收集的。此外，90名健康的老年人提供了480个这些单词的随机样本。所有小组对每个单词的估计出现频率进行评分，评分标准为7分，范围从从未遇到到每天遇到几次。年轻人和老年人组还对每个单词在不同感知领域（如阅读、听力、写作或口语）遇到的频率进行了评分。回归分析结果表明，客观对数频率和意义在主观频率估计中占大部分方差，而邻域大小在评级中占最小方差。对数频率和意义的预测能力取决于主观频率估计的水平。意义能更好地预测不常见词的主观频率，而对数频率能更好地预测常用词的主观频率。我们的讨论集中在主观频率估计与其他熟悉度估计的效用上。所有单词的原始主观频率数据可以在http://www.artsci.wustl.edu/similar到dbalota/labpub.html上获得。
Subjective frequency estimates for large sample of monosyllabic English words were collected from 574 young adults (undergraduate students) and from a separate group of 1,590 adults of varying ages and educational backgrounds. Estimates from the latter group were collected via the internet. In addition, 90 healthy older adults provided estimates for a random sample of 480 of these words. All groups rated words with respect to the estimated frequency of encounters of each word on a 7-point scale, ranging from never encountered to encountered several times a day. The young and older groups also rated each word with respect to the frequency of encounters in different perceptual domains (e.g., reading, hearing, writing, or speaking). The results of regression analyses indicated that objective log frequency and meaningfulness accounted for most of the variance in subjective frequency estimates, whereas neighborhood size accounted for the least amount of variance in the ratings. The predictive power of log frequency and meaningfulness were dependent on the level of subjective frequency estimates. Meaningfulness was a better predictor of subjective frequency for uncommon words, whereas log frequency was a better predictor of subjective frequency for common words. Our discussion focuses on the utility of subjective frequency estimates compared with other estimates of familiarity.
