Leveraging occasional reinforced extinction via mental imagery of the unconditioned stimulus to optimize extinction learning
Occasionally presenting the unconditioned stimulus (US) during extinction training (occasional reinforced extinction, ORE) either unpaired or paired with the conditioned stimulus (CS) provides initial evidence for a less pronounced return of fear. However, translating this approach into clinical practice is challenging due to ethical and practical concerns of exposing patients to the original USs. The present study investigated extinction of fear responses in a novel approach employing ORE using vivid fear imagery of the US instead of actually exposing to it. Three experimental groups underwent differential fear conditioning. Subsequently, participants either received a non-reinforced (standard extinction, N = 25), occasional paired (N = 26), or occasional unpaired (N = 25) reinforced extinction training, followed by assessments for spontaneous recovery, reinstatement, and reacquisition of fear responses. Response patterns during spontaneous recovery, reinstatement and reacquisition showed no benefit from either paired or unpaired imaginative ORE. The current findings suggest that incorporating fear imagery of the US in ORE so far does not result in reducing the return of fear. Further investigation is needed to determine whether imaginal ORE with adjustments could still be a readily applicable strategy for translating the ORE approach into clinical practice.
期刊介绍:
The major focus of Behaviour Research and Therapy is an experimental psychopathology approach to understanding emotional and behavioral disorders and their prevention and treatment, using cognitive, behavioral, and psychophysiological (including neural) methods and models. This includes laboratory-based experimental studies with healthy, at risk and subclinical individuals that inform clinical application as well as studies with clinically severe samples. The following types of submissions are encouraged: theoretical reviews of mechanisms that contribute to psychopathology and that offer new treatment targets; tests of novel, mechanistically focused psychological interventions, especially ones that include theory-driven or experimentally-derived predictors, moderators and mediators; and innovations in dissemination and implementation of evidence-based practices into clinical practice in psychology and associated fields, especially those that target underlying mechanisms or focus on novel approaches to treatment delivery. In addition to traditional psychological disorders, the scope of the journal includes behavioural medicine (e.g., chronic pain). The journal will not consider manuscripts dealing primarily with measurement, psychometric analyses, and personality assessment.
