A Causal Inference Model for the McGurk Effect

View the stimuli

  1. Example stimuli can be view on the CI Stimuli page

System setup

  1. Install GNU R
  2. Download the Code File and Data
  3. Extract the zip file to your Desktop/ or other preferred location

Program Information

We need to ensure R can find the data and code files

1. The main file is mcgurk_causal_inference.R

2. Set the path to be the location of the downloaded files. If you extracted the code pack to your desktop, the path may already be correct

  setwd('~/Desktop/cims_mcg_code_pack/')

3. Run the code as needed to reproduce the graphs

4. Changing values in mcgurk_causal_inference_constants.R will change model predictions

5. There is a code file in the data/ folder that analyzes the behavioral data.
