 When Broadbent does use the word ‘attention’ it is mostly in discussions of attention shifting. His view, at least in his early work, seems to have been that where there is a bottleneck in our information processing capacity there need to be additional mechanisms that control how our limited capacity resources will be deployed. These additional mechanisms of bottleneck-control seem to have been what Broadbent thought of as the attention mechanisms. He never took himself to have given a theory of them, only to have given a theory of where they would be needed. Nor were these mechanisms the topic that was at issue in the debates about attention that Broadbent prompted. Those debates were concerned with questions about the nature and location of the bottleneck itself, not about the factors that determine what, on any particular occasion, gets to pass through it.
