Re: differential mechanism/dose reponse

Susan:

The design feature that you describe here is a strength of your study. However, I don't believe I represented your study otherwise. (Please correct me if I'm wrong about this.)

While I have probably made some provocative statements (after all, this would be a dull and pointless exchange if we all agreed with one another), I don't recall asserting anywhere in the current series of posts that EMDR involves letting people avoid conditioned stimuli (again, correct me if I'm wrong here). And I certainly never said that's ALL that's going on in EMDR. At the very least you should have picked up by now the idea that I think exposure is one of the important ingredients in EMDR. Part 5 of my earlier post explicitly noted exposure and other elements I believe are likely to be active in EMDR (the so-called "common factors" or "non-specifics" of therapy).

In Part 6 of my post, I did ask the question as to how the CONCEPT of DUAL TASK was different from DISTRACTION. Perhaps this is to what you were referring. If so, let me clarify that I was not suggesting that EMDR works through distraction or a dual task. Rather, I wanted clarification of the difference between these two concepts. Shapiro previously suggested that the effects of eye movements may come about through distraction, but then discarded this notion given the data that distraction during exposure may interfere with between-session fear reduction. She apparently is now trying to suggest that the key variable is having a dual task.

Now, as you may know, the world can be divided into two kinds of people: lumpers and splitters, and I'm a lumper. I don't understand the difference between these two concepts. Now mind you, I'm not asserting or denying either one as an explanation for EMDR. I just want to know how the two things differ, because in my mind they seem awfully similar.

Please, I'm being kept busy enough explaining and defending the positions that I have advanced, I don't need to be bogged down defending positions I have not (or at least not yet) advanced.
