A Causal Inference Model for the McGurk Effect
View the stimuli
- Example stimuli can be view on the CI Stimuli page
System setup
- Install GNU R
- Download the Code File and Data
- 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.
