ABSTRACT It is commonly believed that expressions visually signal rich diagnostic information to human observers. We studied how observers interpret the dynamic expressions that people spontaneously produced during a real-life high-stakes televised game. We find that human observers are remarkably poor at recovering what events elicited others' facial and bodily expressions. Beyond simple inaccuracy, people's causal reasoning exhibits systematic model-based patterns of errors. We show that latent emotion representations can explain people's reasoning about the unseen causes of expressions. A hierarchical Bayesian model simulates which events people infer to be the cause of others' expressions by comparing the emotions inferred from the expressions against the emotions people were predicted to experience in various situations. This causal model provides a close, parameter-free fit to human causal judgments, suggesting that humans interpret expressions in the context of emotion predictions generated by a causally-structured mental model of other minds.

You can install the dependencies necessary to regenerate the results and figures using (1) a Docker container (2) a conda environment (3) a pip requirements specification.

Requires Docker. NB Docker is finicky about the cpu architecture. These instructions are for building the image on an arm64 processor. For an example of building the image for an amd64 processor, see .devcontainer/.

### Clone git repo to the current working directory
git clone --branch main https://github.com/daeh/emotionreasoning-cogsci22.git emotionreasoning-cogsci22

### Enter the new directory
cd emotionreasoning-cogsci22

### Build Docker Image
docker buildx build --platform=linux/arm64 --tag emoreasimg .

### Run Container
docker run --rm --platform=linux/arm64 --name=emoreas --volume $(pwd)/:/host/ \
    emoreasimg -u /host/code/wrapper_cogsci.py --projectdir /host/

The container tag is arbitrary (you can replace emoreasimg with a different label).

You can use the conda-lock.yml file to create an environment. Requires conda, conda-lock, and a local installation of TeX Live.

### Clone git repo to the current working directory
git clone --branch main https://github.com/daeh/emotionreasoning-cogsci22.git emotionreasoning-cogsci22

### Enter the new directory
cd emotionreasoning-cogsci22

### Create the conda environment
conda-lock install --name emoreasenv conda-lock.yml

### Activate the conda environment
conda activate emoreasenv

### Run the python code
python ./code/wrapper_cogsci.py --projectdir $(pwd)

The conda environment name is arbitrary (you can replace emoreasenv with a different label).

If the conda-lock.yml lock file cannot resolve the dependencies for your system, you can use the environment.yml file to create an environment with the latest package versions available. Simply replace the conda-lock install line with conda env create -f environment.yml. NB the environment.yml package specifications are not version-locked, so it is possible that there will be package-version idiosyncrasies.

If you use a strategy other than conda or Docker to manage python environments, you can install the dependencies using the requirements.txt file located in the root directory of the project. You additionally need to have TeX Live installed locally.
