About this trial
This study tests the efficacy of a new behavioral intervention with the goal of reducing spontaneous recovery of threat expectancy in healthy adults. This real-time functional magnetic resonance imaging (fMRI) neurofeedback intervention delivers feedback based on a functional connection between the prefrontal cortex and the hippocampus.

Trial outcomes
Primary outcomes
Spontaneous recovery behavior
The investigators will assess neurofeedback related changes in behavioral threat expectancy ratings in a discriminatory Pavlovian conditioning task. Spontaneous recovery is taken as the difference in responding to the conditioned stimulus that was paired with an outcome (CS+) vs. the conditioned stimulus that was not paired with an outcome (CS-) during a test of extinction recall following acquisition and extinction learning.
Secondary outcomes
Neurofeedback learning
The investigators will assess the overall trend in neurofeedback scores over the course of the intervention. If neurofeedback learning is successful, the investigators expect participants in the experimental group to increase the number of positive neurofeedback instances as the experiment progresses.
