The word length effect is one of the cornerstones of trace decay plus rehearsal models (TDR) of memory. Words of long spoken duration take longer to rehearse than words of short spoken duration and as such suffer more decay and are thus less well recalled. The current experiment manipulates both syllable length and spoken duration within words of fixed syllable length in an aim to test the assumptions of the TDR model. Our procedures produced robust effects of both syllable length and spoken duration in four measures of the time it takes to pronounce the different types of words. Serial recall for the same materials produced robust syllable effects, but no duration effects.
词长效应是记忆痕迹衰退加复述模型（TDR）的基石之一。发音持续时间长的单词比发音持续时间短的单词需要更长的时间来复述，因此会遭受更多的衰退，从而回忆效果更差。当前的实验在固定音节长度的单词内同时操纵音节长度和发音持续时间，旨在检验TDR模型的假设。我们的程序在四种衡量不同类型单词发音所需时间的指标上产生了音节长度和发音持续时间的显著效应。对相同材料的系列回忆产生了显著的音节效应，但没有持续时间效应。
