A Review of the Research Supporting (and Not Supporting) Inhibitory Learning Strategies

In my posts about exposure therapy, I’ve written about inhibitory learning theory a bit. I’ve particularly focused on how inhibitory learning theory has supplanted emotional processing theory (EPT) as the best supported model for exposure.

I recently came across a thorough review article that walks through the major inhibitory learning principles and recommended procedures—as well as some not explicitly tied to inhibitory learning –and assess the degree to which these principles and strategies are supported by research to date

The authors conclude:

Collectively, research support for exposure augmentation techniques aimed at optimizing inhibitory learning has fallen short of theoretical expectation in several respects. Though the literature strongly suggests that this theory provides a better mechanistic explanation for the results of exposure therapy than alternatives such as EPT (at least as originally proposed), findings regarding particular enhancement strategies have been quite inconsistent; even among studies in support of specific techniques, the majority of effects are modest at best.

As a summary can’t do justice to this article, I recommend you check it out yourself. If you have any interest in exposure therapy, it is essential reading.
