We study the correlation of the separability dimension of neural data from the value judgment sessions at the end of each day, with the response accuracy of participants on the first day. We find that quick learners do not have a particularly large dimension of neural response patterns on the first day, r = −0.05, df = 17, p = 0.85, as compared to the fourth day, r = 0.56, df = 17, p = 0.01, suggesting that this larger dimension for quick learners takes time to emerge. Pearson’s correlations and parametric p-values reported here; n = 19 in a one-sided test.
