Mittell's book also builds cognitivist assumptions, which means that to Mittell “comprehension is based on the cognitive poetic model developed primarily through David Bordwell’s work on film narration. The core assumption of this approach is that viewers actively construct storyworlds in their minds, and that the best way to understand the comprehension process is through the tools of cognitive psychology.” In line with this, Mittell also draws on Murray Smith's work. Mittell, however, makes a point of stressing that he believes that cognitivist approaches are fully compatible with cultural approaches in terms of understanding and studying television shows, arguing that we "can combine what we know about cultural contexts with the mechanics of mental comprehension and engagement to develop a more pluralistic set of theoretical tools."
