 There is more than one way to understand the explanatory import of Treisman’s claim that the window of attention corresponds to the window within which features are bound. Treisman’s early work presents that claim as an attempt to identify the processes of attention (by telling us that they are the processes of feature integration). In her later work the explanation being offered is no longer simply one in which it is attention that occupies the role of explanandum and binding processes that occupy the role of explanans. Her later claim is that solving the binding problem is one role for the kind of selectivity that attention enables.
