During my weekly meeting with Pierre, I tried to understand from which approach to tackle the PhD work I am involved with. At first we defined the approaches we did not want to pursue further: a) the Mental Representation of Space; b) the cognitive Navigation of space; c) the forming of the idea of the city.
Instead we decided to focus on the language and psycho-linguistic studies, particularly the mutual modeling which happen through the language and the dialogue. Language uses context, in particular space and history, following the principle of the least collaborative effort (Clark)
However other approaches and theoretical branches will be needed, like the cognitive understanding of maps.
