Instead, we need a theory of Why we can rehearse only a limited amount of information at a time. Here we address why we can rehearse only limited information at a time. Articulatory Loop Rehearsal limitations are due to limits in how long it takes verbal material to decay, not how many items we can store. Word length effect. How long it takes to read words predicts how many words will be remembered.
Articulatory loop is called the phonological loop due to evidence that it involves speech.
We can rehearse about 1.5 seconds of verbal material before it decays. These hold information for use by a central executive. There is evidence that a particular area of the frontal cortex is involved in working memory. How well we have practiced it. Subjects learn some sentences.
