negative cases

Especially after today's conversation, the top line on pg. 257 stuck out as if already highlighted: "(See Nelson, 1988, for negative cases)". Not only did Nelson isolate Carmen's case in her own chapter, but the rest of the negative cases are found in a different publication all together? Maybe that actually means something different, but that's what it seemed like to me. I understand that Carmen's case was long, so having its own chapter made sense for organizational purposes, but the lack of detail everywhere else was more disturbing. We talked a lot about this in class today, so I don't want to be too repetitive, but this was interesting to me. It seems like class discussion seems to predict the next day's reading on a fairly consistent basis!
