Augmenting Cognitive Architectures to Support Diagrammatic Imagination

Diagrams are a form of spatial representation that supports reasoning and problem solving. Even when diagrams are external, not to mention when there are no external representations, problem solving often calls for internal representations, that is, representations in cognition, of diagrammatic elements and internal perceptions on them. General cognitive architectures—Soar and ACT‐R, to name the most prominent—do not have representations and...
