SEDSU - Stages in the Evolution and Development of Sign Use|
There remains, despite centuries of debate, no consensus about what makes human beings intellectually and culturally different from other species, and even less so concerning the underlying sources of these differences. The main hypothesis of the project Stages in the Evolution and Development of Sign Use (SEDSU) is that it is not language per se, but an advanced ability to engage in sign use that constitutes the characteristic feature of human beings; in particular the ability to differentiate between the sign itself, be it gesture, picture, word or abstract symbol, and what it represents, i.e. the “semiotic function” (Piaget 1945).perception and categorisation (Workpackage 2)
iconicity and pictures (Workpackage 3)
space and metaphor (Workpackage 4
imitation and mimesis (Workpackage 5)
intersubjectivity and conventions (Workpackage 6)
The project is an interdisciplinary collaboration between Lund University, Goldsmiths - University of London, Portsmouth University, MPI-EVA Leipzig, INCM-CNRS Marseille and ISTC-CNR Rome, founded by the EU Sixth Framework Programme. The single research effort will afford new possibilities for methodological innovation, and the collection and analysis of new types of comparative data. The central research objective of the project is to investigate the developmental and comparative distribution of semiotic processes, and their effect on cognition.
For this purpose we study five cognitive domains, each one corresponding to a Workpackage in the Project,
and study their interrelations and role in the development of sign use:
These domains are all characterised by stage-like developmental profiles which we expect to correlate with differences in sign use. The investigations in the different domains will be carried out in parallel, with extensive sharing of methodologies and results. Since we hold that each domain plays a key role in providing cognitive prerequisites for the development of sign use, and at the same time is transformed by the acquisition of the latter, we expect to find considerable similarities and interactions between developments in the domains. Finally, we intend to integrate all the results of the SEDSU project in a coherent theory of semiotic development.
