Data for: Exacerbation of the credit assignment problem in rats with lesions of the medial prefrontal cortex is revealed by Bayesian analysis of behavior in the pre-solution period of learning
Description
An excel spreadsheet of trial by trial behavioural data from 68 rats performing an ID/ED attentional set-shifting task. The file contains columns to specify rat ID; stage of task; which stimuli (i.e., a pair of bowls containing scented digging media) were presented in which location; which location/stimulus the rat chose; whether it sampled both bowls before digging in one. The likelihoods associated with each of the potential 'hypotheses' are shown: If the rat sampled only one of the bowls, spatial hypotheses are given higher weight than if it sampled both. Posterior probabilities are calculated by multiplying the prior (which is the posterior probability from the previous trial) by the likelihood. The posterior probabilities are then normalised (i.e., divided by the sum of all posterior probabilities) to give a 'b-value'. The final columns gives an example of how the b-values can be calculated in Excel, although they were actually calculated using Matlab.
