The counterfactual simulation model is implemented in python 3.7 using the physics engine pymunk. The model.py file contains the model code.

• to run the counterfactual simulation model, cd into code/python/

• you can then run python simulation_2ball.py 1 where the last number indicates the degree of noise that should be applied in the counterfactual simulation

• simulation_teleport.py and simulation_3ball.py are used for generating model predictions for the Experiments 2 and 3 in the paper

• in each simulation file, you can set the following parameters:

  • n_simulations: number of counterfactual simulations to run
  • trials: which trials to run (specified as a list)
  • noise: noise applied to the ball's motion in the counterfactual situation
  • record_data: logical value whether or not to record the outcome of the simulations
  • experiment: experiment indicator
  • animate: logical value whether or not to show animations of the simulations

• to create videos of the different clips, you can run the make_videos.sh script like so bash make_videos.sh '2balls' 0 (this would make a video of the first clip in Experiment 1)
