The study of expertise is difficult to do in a laboratory environment due to the challenge of finding people at different skill levels and the lack of time for participants to acquire mastery. In this paper, we report on two studies that analyze naturalistic gameplay data using cohort analysis to better understand how skill relates to practice and habit. Two cohorts are analyzed, each from two different games (Halo Reach and StarCraft 2). Our work follows skill progression through 7 months of Halo matches for a holistic perspective, but also explores low-level in-game habits when controlling game units in StarCraft 2...

: 27 Background: Oncologists engage in emotionally charged conversations with patients and families about prognosis, goals of care, and end of life transitions. Many oncologists lack key skills for guiding patients through such conversations. Key skills include posing open ended questions to elicit the patient's perspective, using silence effectively, and responding to emotion with empathy. We previously described a communication skills curriculum for first year medical oncology fellows consisting of a series of one hour monthly seminars (Epner and Baile, Academic Medicine, 2014)...
