A comparison of concept formation strategies in pattern recognition tasks

We used two experiments to explore the effects of two kinds of strategies (nonanalytic and analytic) in concept formation. In Experiment 1, nonsense shapes were used as stimuli, which created ill-defined categories of concepts to be discovered by the subjects. In Experiment 2, highly recognizable geometrical patterns were used as stimuli, hereby placing an emphasis on the identification of highly salient categories of concepts. Subjects were better able to classify stimuli correctly in both experiments relying on memory (nonanalytic strategy) than on rule learning (analytic strategy). Here we discuss implications of nonanalytic strategy for understanding the nature of creativity.
