A brief history of the model
1990 – Formulation of the principles of dimensional overlap; first stab at the representational model and taxonomy.
1991 – Experimental exploration and verification
1992 – Full development of the taxonomy and the representational model
1994-1995 – Further experimental verification
By this time, the limitations of the representational model were becoming apparent: ordinal predictions only; no predictions in the size of effects; and neglect of the importance of time-course information.
1996 – First computational model, specifically targeting the SS x SR task and timecourse information.
2000 – Full development of the computational model and testing with wide variety of tasks (Types 1-8)
(?) – The next step in the evolution of the model will be the development of The Cognitive Neural Basis of Dimensional Overlap.
