Looking for articles on specialty-specific learning format preferences

Does anyone know of any literature/journal

articles out there on the preferred format of learning for the different specialties? A reader just asked if I knew of any specific to Ob-Gyn docs, and I couldn't find anything on a quick search, so I thought I'd ask you all instead. I wrote up a great session from last year's CME Congress that looked at learning preferences for

cardiologists, psychiatrists, pediatricians, and general surgeons here, but was hoping there was a lot more out there than what I've seen so far.

If you know of any such research, please leave a comment below, or drop me an e-mail. Thanks in advance for any help you can provide.
