Code and data for "An Active Inference Model of Trust Game Behavior"

This is a zipped version of the github reposiory and behavioral data for an Active Inference model of trust game behavior. It contains the software for simulation, model inversion, model comparison, classification and parameter/ prediction recovery. To use this code and reproduce any results or figures, follow the steps detailed in our readme file below.

To reproduce all results and run the code, follow these steps: ### 1. Clone the repository ```bash git clone [e-mail]:fb04/ag-endres/pymdp_depression.git ``` ### 2. Install in editable mode Navigate to the `src/` directory and run: ```bash pip install -e . ``` --- ## 🗂️ Repository Structure ``` pymdp_depression/ ├── pyproject.toml ├── README.txt ├── .gitignore ├── data/ ├── notebooks/ │ └── # Contains all plotting notebooks in order of appearance in the manuscript ├── src/ │ └── pymdp_depression/ │ ├── model/ │ ├── classification/ │ ├── model_comparison/ │ ├── simulations/ │ ├── optimization/ │ ├── recovery/ ├── archive/ ``` --- ## 🔈 Naming conventions The model variants have slightly different names in the paper vs. in the optimization algo for readability reasons: Paper name --> repo name --- 1) ABC --> fits_alpha16 2) ABCE --> with_E 3) ABCDE --> with_EandD 4) ABCDEα --> with_E_and_alpha 5) ABCDE_lrAlrB --> hyperparam_opt 6) ABCD_policy2 --> incr_policy_horizon --- ## 📊 Reproducibility All figures in the manuscript can be reproduced using the notebooks found in the `notebooks/` directory. * The notebooks are **numbered in the order they appear in the paper**. * Each notebook imports the necessary functions from the `model`, `simulations`, `optimization`, and `recovery` submodules. * All figures are generated directly from data stored under: ``` data/results/... ``` --- ## 📚 Citation Please cite our manuscript - once published, you will find the full citation on Google Scholar or here: https://eckertal.github.io/personal-website/publications/
