We also investigate how the learning of value emerges throughout the first day. We examine how performance accuracy changes across the three learning sessions and value judgement session on the first day of training where the greatest individual differences were observed, and its correlation with stimuli separability dimension on the final day of training. We see that this correlation increases from r = 0.38 in the first learning session (top left) to r = 0.56 by the end of the first day in the value judgement session (bottom right). These data suggest that this relationship between the dimension of neural data and the response accuracy of participants emerges across sessions on the first day of training. Note that in contrast to the non-parametric permutation test used to yield p < 0.001 for the bottom right data in the main text, here we simply provide the parametric p-values from the one-sided Pearson’s correlation (df = 17, n = 19) which are much less computationally intensive to estimate.
