The Importance of Conceptual Origins: The Case of the Just-Right Challenge.

Core concepts in occupational therapy have often developed over time with contributions from multiple clinicians and scholars. This makes it difficult to determine exactly from where, or from whom, ideas originated. Without original sources, we cannot chart the historical development of ideas and honor those whose scholarship made it possible. This article documents the process undertaken to properly cite one such common concept in occupational therapy, the just-right challenge; illustrates the value of doing so; and advocates for the importance of thorough historical scholarship.
