The human amygdala in threat learning and extinction

FEARTUS project This repository contains the behavioral and questionnaire datasets used in the FEARTUS project, investigating the causal role of the human amygdala in threat learning and extinction. All datasets are formatted for direct use in the FEARTUS R analysis pipeline (GitHub code repository: FEARTUS). Data files scr_df.RData Trial-level skin-conductance response (SCR) data for all experimental phases: acquisition (acq) threat retention (retent) extinction (ext) recovery following reinstatement (reinst) re-extinction (reext) tus_quest_df.RData Questionnaire data on participants’ sensory experiences and placebo-related beliefs about TUS: auditory tactile thermal placebo Variables correspond to items assessed during post-experiment debriefing. cs_quest_df.RData Post-experiment ratings of each CS (threat vs. safety) collected after task completion: retrospective threat probability valence arousal These ratings reference the acquisition phase. data_RW_TUS_acq.rds Acquisition-phase SCR data formatted for input into the hierarchical reinforcement-learning (Rescorla–Wagner) models.
