We will implement an asymmetric version of this model that allows for differential updating of value estimates in response to positive and negative prediction errors (see here).https://wiki.thewiselab.org/docs/computational_modelling/tutorial/2.-implementing-an-update-function/Mon, 01 Jan 0001 00:00:00 +0000https://wiki.thewiselab.org/docs/computational_modelling/tutorial/2.-implementing-an-update-function/Implementing an update function First, we need to create a function that implements the core update method for our model (i.https://wiki.thewiselab.org/docs/computational_modelling/tutorial/3.-selecting-actions/Mon, 01 Jan 0001 00:00:00 +0000https://wiki.thewiselab.org/docs/computational_modelling/tutorial/3.-selecting-actions/Selecting actions In most learning tasks we are asking participants to select different actions or stimuli based on their estimated value.https://wiki.thewiselab.org/docs/computational_modelling/tutorial/4.-updating-value-across-trials/Mon, 01 Jan 0001 00:00:00 +0000https://wiki.thewiselab.org/docs/computational_modelling/tutorial/4.-updating-value-across-trials/Updating value across trials So far, we’ve implemented a function that will select an action and update its value estimate based on the reward received for a single trial.https://wiki.thewiselab.org/docs/computational_modelling/tutorial/5.-running-the-model-for-multiple-subjects/Mon, 01 Jan 0001 00:00:00 +0000https://wiki.thewiselab.org/docs/computational_modelling/tutorial/5.-running-the-model-for-multiple-subjects/Updating value across subjects The model we’ve implemented so far works for a single subject, but we will typically want to run it for multiple subjects.https://wiki.thewiselab.org/docs/computational_modelling/tutorial/6.-model-fitting-using-mcmc/Mon, 01 Jan 0001 00:00:00 +0000https://wiki.thewiselab.org/docs/computational_modelling/tutorial/6.-model-fitting-using-mcmc/Model fitting using MCMC Next, we’ll try fitting our model to some simulated data. Imports First, we import necessary packages.
