The purpose of this study was to investigate relationship between aptitude, task performance, and solution strategy of the three-term series problem, which is one of the most simple deductive reasoning. A sample of 25 subjects was selected from a larger sample of 121 female college students. They had previously taken the Kyoto University SX Intelligence Test and participated in the experiment in which, two premises of the problem being presented successively, they indicated whether three terms were ordered linearly or not. Six alternative models each corresponding to different strategies were supposed and 16 of subjects were divided into four groups by testing which model each subject's data were fit to. The results were that the correlation between general intellectual aptitude and the performance was not significant, that some strategies were advantageous for accuracy, that subjects of some strategy groups had higher intellectual abilities, and that the best strategy for accuracy did not necessarily require the highest abilities to be executed. Aptitude didn't have a direct effect on performance, but on strategy.
