The free online magazine The Reasoner has recently published an interview with me in their February 2010 issue.  Much of it is discussing argument mapping and its uses.  However the first third or so of the interview covers my earlier work in the foundations of cognitive science (distributed representation, dynamical systems and such topics).

Thanks to Kevin Korb for initiating and conducting the interview.


KK: What are argument maps and why are they important?

TvG: Typically an argument map is a box-and-arrow or node-and-link diagram showing the relationships among propositions in some piece of informal reasoning or argumentation. Argument mapping is thus “semi- formal”, blending formal graph structure with natural language. You can think of argument mapping as addressing a design challenge: come up with a maximally transparent way of representing informal reasoning and argumentation for human thinkers, one that makes the reasoning as explicit, rigorous and yet easily comprehensible and communicable as possible.  From this point of view, the various forms of argument mapping around today—such as the one embodied in the Rationale software—as particular attempts to come up with that optimal format. No doubt improved schemes, supported by more sophisticated technologies, will arise in coming years.

KK: How does your understanding of their importance relate to what you know about human cognition?
TvG: The diagrammatic format of typical argument maps is useful for humans with cognitive machinery dominated by powerful visual systems. Diagrammatic argument maps complement the idiosyncratic strengths and weaknesses of our evolutionarily-endowed cognitive equipment. For example, argument maps compensate for our limited short-term memory, providing a stable external representation of complex inferential webs. At the same time they facilitate access to this externally represented information by exploiting our powerful visual scanning capacities. In computer terms, our eyes constitute the high-capacity bus connecting the argument map, stored in external RAAM, to our brains as the CPU…
