Post-choice Bias

Repository for post-decision confirmation bias paper.

You can obtain the data for the perceptual task from: https://doi.org/10.6084/m9.figshare.7048430

If you use the data or the code, please cite: Talluri, B. C., Urai, A. E., Tsetsos, K., Usher, M., Donner, T. H. (2018) Confirmation bias through selective overweighting of choice-consistent evidence. Current Biology 28, 1-8. doi: 10.1016/j.cub.2018.07.052

The repository is organized into the following folders:

  1. Perceptual_Experiment: Code to run the perceptual experiment. This code uses Psychtoolbox-3 (http://psychtoolbox.org/) on MATLAB.
  2. Data: Contains raw data from both perceptual and numerical tasks. The data for numerical task was obtained from Bronfman et al. 2015 (https://datadryad.org/resource/doi:10.5061/dryad.40f6v). The folder also contains analysis-ready data files that are called by the analysis scripts, to replicate the figures and results in the paper. In addition, matlab scripts that give the analysis-ready data files from the raw data files are also provided in the folder. All data files are in csv format.
  3. Code: Contains all analysis scripts to replicate the figures and other results in the paper.

Note: All the scripts have been commented for readers to understand and any functions used in these scripts that are not built-in have been added. However, please understand that the description may not be complete and if you run into any issues while running the code please contact Bharath Chandra Talluri (bharathchandra.talluri@gmail.com) or Anne Urai (anne.urai@gmail.com).
