Code and data for Feher da Silva, C., Hare, T.A. Humans primarily use model-based inference in the two-stage task. Nat Hum Behav (2020). https://doi.org/10.1038/s41562-020-0905-y

This project contains the code required to run the spaceship and magic carpet tasks mentioned in the paper:

Feher da Silva, C., Hare, T.A. Humans primarily use model-based inference in the two-stage task. Nat Hum Behav (2020). https://doi.org/10.1038/s41562-020-0905-y

The experiments inside the magic_carpet and spaceship directories require Python 2.7 and PsychoPy 2 to run. They should run on standalone PsychoPy version 1.90.3. Just run the exp.py script in each directory.

We used the following fonts to display the instructions for the participants:

• Noteworthy-Bold.ttf for the spaceship task
• OpenSans-SemiBold.ttf for the magic carpet task

These fonts are not included in this repository because of the license. To run the tasks, you will need to change the path to these fonts. Where you have to do this is indicated in the exp.py file.

The behavioral data (choices and questionnaires) can be found in the results directory.

The data analyses and simulations are still being added to this repository. They use Python 3.6 and the Pipenv package to manage dependencies.
