Abstract : The research described in this final report continues, and greatly extends our ongoing investigations of basic, elemental, cognitive processes in humans. During the period covered by the report we focussed on validating the original dimensional overlap model (DO-'90: Kornblum, Hasbroucq & Osman, 1990), testing some of its fundamental predictions, and recasting the model itself in a computational form. These efforts appear to have been successful. The original model and its taxonomy have become an effective integrative framework in an important domain of human performance (stimulus-stimulus, and stimulus-response compatibility in the broadest sense of these terms), and encompass, in a principled manner, a broad family of performance tasks representing classic problems in human cognition (e.g., Stroop and Stroop-like tasks, Eriksen and Eriksen-like paradigms, and Simon and Simon-like effects). Our work has resulted in the publication of 10 peer reviewed articles, with 4 manuscripts presently under review, one dissertation, and 17 presentations at professional meetings. The model has also contributed an important theoretical perspective to investigators working on psychophysiological and neurophysiological mechanisms of response production, and stimulus-response association processes. The principal goal for our future work is to develop and extend the model further, and test its new properties and implications. Some of these new properties span inter- as well as intra-trial phenomena, and mark the beginnings of the theoretical and empirical bridges that we were hoping, originally, to be able to build between the family of SRC tasks, and the central problems of cognition.
