Studies of clinical reasoning are essential if we are to extend our knowledge of occupational therapy practice, better communicate our work to clients and colleagues, and reveal to our students the nuances of therapy that cannot be gained from texts. However, accessing therapists' clinical reasoning is not an easy task because these cognitive processes can be studied only indirectly. The aim of this article is to promote the study of clinical reasoning by reviewing a new approach to data collection in this field. To achieve this purpose, the article outlines current data collection methods, such as the think-aloud method written notes, free recall, and audio-assisted and video-assisted recall. A novel method involving a head-mounted video camera is described, and details are provided on a modified approach to debriefing using video-assisted recall. Anecdotes from the authors experience of using this technology illustrate the text.
