Going back to the RAM metaphor, in the computing world the bus speed of the RAM is almost as important as the size of the RAM module. If we believe that this computational metaphor holds in human beings, the speed at which information is entered into, manipulated, and ultimately retrieved from working memory will predict performance in a different way relative to what limitations in WM capacity would dictate. Back to the computing metaphor, when computers max out their RAM, they either recruit resources from the hard disk (swap) or they maintain a bottleneck at which subsequent information cannot be processed until previous information processing has been completed. The nature of this bottleneck is heavily mediated by the bus speed because, for example, if information can be processed quickly, then it can be entered, manipulated, and retrieved from working memory faster, reducing the amount of time that the information needs to sit idle in the RAM storage banks. Though untested, this scenario may manifest itself in humans as well and initial support can be provided by the substantial overlap in the predictability of PS and WM task performance on more complex cognitive tasks.
