“…Although the issue of whether making errors is beneficial or detrimental to learning remains controversial (Ashby, Maddox, & Bohil, 2002;Edmunds, Milton, & Wills, 2015;Potts & Shanks, 2014;Seabrooke, Hollins, Kent, Wills, & Mitchell, 2019), it is undeniably the case that, in the current experiments, single feature pretraining is not well matched to the polymorphous control condition in terms of the number of classification errors participants produce. It is therefore possible that the SFPT advantage comes from this difference in error frequency, rather than from the provision of deterministic feature-category associations assumed to be the cause by the dimensional summation hypothesis.…”
