For example, it says (concerning using mental imagery) "This result comes as no surprise to anyone with even basic training in NLP. Imagining “themselves performing this act, with as much sensory detail as possible” has been a standard and essential part of rehearsing or “future-pacing” any behavioral change."
A quick search shows that behavior rehearsal was part of non-NLP since at least the early 1970s. See for example http://www.ncbi.nlm.nih.gov/pmc/articles/PMC1311981/ , "Training predelinquent youths and their parents to negotiate conflict situations":
> In response to parental requests for assistance in dealing with adolescent problem children, three parent-child pairs were taught negotiation responses to hypothetical conflict situations using behavior rehearsal and social reinforcement. The negotiation process was separated into component behaviors that were practised during simulations by each youth and his parent under the direction of trainers. Results indicated that (a) the procedures were successful in training youths and their parents in negotiation behaviors that produced agreements to conflict situations, and (b) these behaviors generalized to actual conflict situations in subjects' homes.
or a clinical trial from 1981 at http://www.ncbi.nlm.nih.gov/m/pubmed/7205244/ , "The treatment of social phobia. Real-life rehearsal with nonprofessional therapists."
> It was concluded that repeated behavior rehearsal, both in the clinic and in real life is a cost-effective treatment procedure for many social phobias. The approach is straightforward and can be applied by nonprofessionals, including the patients themselves, after limited training and with minimal supervision.
Further, the original synopsis at http://digest.bps.org.uk/2011_06_01_archive.html points out that it's not just imagery which is important, but that there was question: why was there a seeming
> contradiction with earlier research showing implementation intentions are most helpful to those with compromised willpower? Churchill and Jessop can't be sure, but they said one possibility could be because their task of eating more fruit and veg is more complex than some of the lab tasks studied previously.
