This project contains the full code for an Attractor Network Model (ANM) simulating Changes of Mind (CoM) in voluntary action, as reported in:
Löffler, Sylaidi, Fountas & Haggard (2019). "A hierarchical attractor network model of perceptual versus intentional decision updates." Nature Communications 12.1 (2021): 2020.
The model is implemented in both Python and Matlab.
-
The Python folder contains all code required to implement the model (ANM.py) and perform model optimization based on Powell's methods (fmin_powell.py).
-
The Matlab folder contains code that simulates a specified number of trials (ANM_runSim.m) and plots single-trial model outcomes (plotTrials.m).
