AbstractWe herein investigate the following question:(Q3) What does the contemporary craft of character design (by human authors), which is beyond the reach of foreseeable AI, and which isn't powered by any stunning, speculative, AI-infused technology (immersive or otherwise), but is instead aided by triedand-true "AI-less" software tools and immemorial techniques that are still routinely taught today, imply with respect to today's computational cognitive architectures?Because this is a large question, we narrow its scope so as to be able to productively consider it in the space of but the present chapter. Our narrowing is accomplished by making three moves. First, we anchor the discussion to a simple, single story (Double-Minded Man) populated by only a pair of characters, and crafted in a particular "AI-less" software system taught and used by scriptwriters today. Second, we focus specifically on the expressivity of a cognitive architecture, in light, specifically, of two expressivity challenges that arise from considering Double-Minded Man and its characters. And third, we partition cognitive architectures, with respect to these challenges, into three categories. The first category is composed of those architectures that appear to have no chance of meeting the challenges; the second, of those that perhaps meet the challenges; and the third, of those that clearly meet the challenges. As shall be seen, the cognitive architecture ACT-R falls into the second category, and CLARION falls into the third. Encapsulating, then, here's the core of our answer to (Q3):(AQ3) While ACT-R and cognitive architectures that have its level of expresivity or less are perhaps able to support cognitive models of characters in narrative, CLARION certainly has a level of expressivity sufficient to capture such characters. While we know of no other cognitive architecture that has this high level of expressivity, any architecture with this level of expressivity would at least be a candidate for the robust modeling implied by contemporary story and character design.
