Opening with a discussion of the role of computer simulation in cognitive psychology, this paper proceeds to examine the major perspectives on computer simulation as a tool for theoretical research on cognitive processes. The claim that computer simulation enforces rigor in theory specification is analyzed; the use of simulation as a method for…

This article examines a current, explicit, central theory accounting for the observed flexibility in motor performance: the generalized motor program with a multiplicative rate parameter. Reanalysis of data reported in the literature and a study of skilled typewriting show that a generalized motor program generally does not fit observed…
