How Hostility Unfolds During Online Argumentation – Study 3 and 3R: fMRI Data and Code

Repository SummaryThis repository contains the analysis code and MRI data associated with the manuscript:"How Hostility Unfolds During Online Argumentation". All figures reported in the manuscript can be reproduced using the scripts provided in the `code` directory and the MRI data included in the `data` directory.To replicate the second-level fMRI results, download the code folder and run the following python scripts."python_rsa_parametric_tox_received.py", Fig.3C, D."python_rsa_received_dislike_like_period.py", Fig.3F, G."python_rsa_amplification_toxicity.py", Fig.4A, B."python_rsa_amplification_dislike.py", Fig.4D, E."python_cloudFig_download_neurosynth_dataset.py" and "python_cloudFig_generation.py", Fig.3E, H, and Fig. 4C, F.Script "python_believability_corr_RSA_wb_cluster_based_Perm.py", Supplementary Fig.3.4.The raw MRI dataset includes structural (T1), functional (BOLD), and fieldmap imagesfor Study3 and Study3R. All MRI data were preprocessed using FSL version 6.0.7.15. The resulting multi-voxel activity patterns were used as inputs for the representational similarity analysis (RSA) implemented in matlab_searchlight_matlab_HDF5_fullrsa.m. The bash scripts included in this repository were used for parallel computing.Programming environment:The Python environment can be recreated using the following packages.Python==3.13numpy==2.3.5scipy==1.17.0pandas==2.3.3nibabel==5.3.3nilearn==0.11.1nimare==0.6.0h5py==3.15.1torch==2.9.1joblib==1.5.3matplotlib==3.10.8wordcloud==1.9.5Matlab versionR2024aBash versionGNU bash, version 3.2.57(1)-release (arm64-apple-darwin25)Copyright (C) 2007 Free Software Foundation, Inc.Repository structureproject||-- data|  |-- event_txt_files_Study3.zip    # Event timing of Study3 for RSA|  |-- event_txt_files_Study3R.zip    # Event timing of Study3R for RSA|  ||  |-- Fieldmap_Image_Study3       # Fieldmap images of Study3|  |-- Fieldmap_Image_Study3R      # Fieldmap images of Study3R|  ||  |-- Raw_BOLD_Image_Study3       # BOLD images of Study3|  |-- Raw_BOLD_Image_Study3R      # BOLD images of Study3R|  ||  |-- Preprocess_BOLD_Image_Study3   # Preprocessed BOLD images without smoothing for Study3|  |-- Preprocess_BOLD_Image_Study3R   # Preprocessed BOLD images without smoothing for Study3R|  ||  |-- T1_Image_Study3          # T1 images of Study3|  `-- T1_Image_Study3R         # T1 images of Study3R|`-- code  |-- bash_*              # Bash scripts for first-level preprocessing and parallel computing  |-- python_*             # Code for second-level fMRI analysis and result replication  |-- matlab_*             # Code for first-level representational similarity analysis  `-- resources             # Resources and intermediate results necessary for replication
