I would view them as quite different techniques, to be honest. I actually think it’s quite important to be clear what the underlying mechanism is in different psychological practices. In CBT we tend to place a lot of emphasis on that because clients usually gain more benefit from an exercise when they’re clear about the purpose and how it works — that often requires carefully distinguishing techniques that might appear superficially similar. Of course, sometimes a technique may be effective for several different reasons. Nevertheless, I believe it’s in our interests to try to clarify what the mechanism is that we’re aiming to employ.
