Study Summary
The primary purpose of this study is to investigate the effects of tDCS timing on extinction memory in PTSD. A total of 90 participants will be randomized equally across one of three groups: 1. One group receiving active stimulation during extinction followed by sham stimulation during consolidation 2. One group receiving sham stimulation during extinction followed by active stimulation during consolidation 3. One group receiving sham stimulation both during extinction and consolidation This study also includes an online sub-study (Aim 2) focused on contextual processing along the PTSD spectrum. The online study tests if there is an association between threat and non-threat learning in contextual and non-contextual situations. A maximum of 500 participants will be recruited using an online, panel-based platform.
Primary Outcome
Main protocol: Threat reactivity as quantified by skin conductance responses to a conditioned and subsequently extinguished stimulus versus a never conditioned stimulus.
