作者调查了工作记忆广度任务受干扰影响的可能性，以及干扰对广度和其他测量之间的相关性的贡献。年轻人和老年人要么以标准格式接受跨度任务，要么以旨在减少干扰影响而不影响容量需求的格式接受跨度任务。然后，参与者阅读并回忆一段简短的散文。减少跨度任务中的干扰量提高了跨度分数，重复了先前的结果（c.p. May， L. Hasher, & M. J. Kane, 1999）。同样减少干扰的操作，提高广度，实质上改变了广度和散文记忆之间的关系。这些结果表明，跨度受干扰的影响，跨度的年龄差异可能是由于克服干扰能力的差异而不是能力的差异，干扰在跨度与其他任务之间的关系中起着重要作用。
The authors investigated the possibility that working memory span tasks are influenced by interference and that interference contributes to the correlation between span and other measures. Younger and older adults received the span task either in the standard format or one designed to reduce the impact of interference with no impact on capacity demands. Participants then read and recalled a short prose passage. Reducing the amount of interference in the span task raised span scores, replicating previous results (C. P. May, L. Hasher, & M. J. Kane, 1999). The same interference-reducing manipulations that raised span substantially altered the relation between span and prose recall. These results suggest that span is influenced by interference, that age differences in span may be due to differences in the ability to overcome interference rather than to differences in capacity, and that interference plays an important: role in the relation between span and other tasks.
