Irrelevant Speech Eliminates The Word Length Effect. The word length effect is a phenomenon that involves a human being's capacity to recall short words better than long words. Words that take less time to pronounce, therefore, are more easily remembered. There are two well-developed explanations of the word length effect. These are Baddeley's working memory model (WMM) and Nairne's feature model. This paper compares the predictions of each view concerning interactions between word length and irrelevant speech. 4.5 pgs. 3 f/c. 2b.
