• A total of 455 cases, 5 tasks by 91 subjects, of the simplest form of concept identification with stimuli, each consisting of 5 letters, were stratified into 8 groups according to strategies used by the subjects. Two representative strategies were identified through verbal reports of the subjects and also differences in performance: whole-letter strategy to pursue all of an appropriate set of letters simultaneously and one-letter strategy to test one letter at a time and without replacement. Both strategies were simulated by a computer. All the results, the whole cases, 8 separate groups, computer simulations, were also fitted by the original form of Bower-Trabasso stochastic model (1964). Two main findings were as follows: there are substantial individual differences in regard to strategy and the stochastic model gives apparent good fits to each of the heterogeneous set of data which were generated through qualitatively different strategies, provided the value of a parameter, the probability of hitting the correct hypothesis, is appropriately defined.
