ABSTRACT
These results cast severe doubts on the adequacy of SST models data in choice reaction tasks and in memory scanning. It should be noted that the distributional inequality (equation (8» is based on weaker assumptions and is thus a test of a broader class of SST models than the usually tested predictions concerning changes in mean RT which require the assumption of a constant mean duration per processing step. It seems therefore desirable to conduct the distributional tests under conditions where SST models have been shown to be successful with respect to mean RT's, in order to see whether the model passes the more general but possibly also more stringent test.
