While at Dalhousie as a mature student studying cognitive and social psychology I had a conversation with the chair of the history department, who's introductory course I had taken in second year.
I suggested that some aspects of cog-psych (What we might now call "social cognition") might shed some light on matters of historiography.
I suggest today that this approach can be enabled by our best information practices i.e. studying a topic in one discipline brings up points that might be best treated by another. Say, in Poli Sci, studying the war in Iraq, we would touch on the cultural aspects of policy, on matters of macro- and micro-economics ... in short, psychology, economics, sociology and anthropology would come into play.
Conventional techniques strive to focus, quite appropriately. But student engagement, I suggest, would be best nurtured by a more full-spectrum approach.
