Abstract
The purpose of this study was to reconsider the concept of play in order to break the current deadlock between
psychological research and theories of play. First, regarding research problem formation, it was argued there would be
no need to answer why people play but need to consider what play is to solve the problems. This study clarified the
limitations of methodologies based on either extreme subjectivism or objectivism, and adopted structuralism instead.
Second, a new model for understanding the structures of play was advanced through a discussion of studies of play
conducted by Piaget and others. Third, it was suggested that this structure model, could elucidate both the similarities
and differences between play and exploratory behaviors and, further, that the model could be applied to qualitative
research. Finally, future research issues were discussed.
