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.
