之前的几项研究表明，短词的记忆广度比长词的记忆广度大。这种效应即使在短词和长词的音节和音素数量相匹配的情况下也会发生，从而为亚声发音是记忆广度的一种机制提供了证据(Baddeley，Thomson，&Buchanan，1975)。本文报道的三个实验进一步考察了词长对广度任务的发音决定因素。实验一重复了S的发现，即当刺激中的单词音节数不同时，词长对听觉和视觉广度的影响。实验2和实验3表明，当广度任务中的单词在音节和音素数量上匹配时，词长的影响被消除，但在发音手势的持续时间和/或复杂性方面不同。这些结果表明，在广度任务中，决定词长效应大小的是单词的语音结构，而不是其实际发音特征。
Several previous studies have shown that memory span is greater for short words than for long words. This effect is claimed to occur even when the short and long words are matched for the number of syllables and phonemes and so to provide evidence for subvocal articulation as being one mechanism that underlies memory span (Baddeley, Thomson, & Buchanan, 1975). The three experiments reported in this paper further investigate the articulatory determinants of word length effects on span tasks. Experiment 1 replicated Baddeley et al.'s finding of an effect of word length on auditory and visual span when the stimuli consist of words that differ in terms of the number of syllables. Experiments 2 and 3 showed that the effects of word length are eliminated when the words in the span task are matched for the number of syllables and phonemes but differ with respect to the duration and/or complexity of their articulatory gestures. These results indicate that it is the phonological structure of a word and not features of its actual articulation that determines the magnitude of the word length effect in span tasks.
