From: Greater mindful eating practice is associated with better reversal learning
Intervention effects on reversal learning. (a) The mindful eating (ME) and educational cooking (EC; active control) intervention did not differentially affect reversal learning from reward or punishment. Overall participants were impaired at learning from reward relative to punishment (main effect Valence: F(1,63) = 10.1, p = 0.002, ηp2 = 0.138). (b) Valence-dependent reversal learning (i.e. mean error rates on trials following reversals signaled by unexpected reward - unexpected punishment) was not associated with the amount of time participants invested in either intervention (p’s>0.15). (c) Better valence-independent reversal learning (i.e. lower mean error rates on trials following reversals in general ([unexpected reward + unexpected punishment]/2)) was related to increased time investment in the mindful eating (dashed line: r = −0.464, p = 0.005), but not the educational cooking training (solid line: r = 0.117, p = 0.538). Note that whereas the statistics were performed on the transformed error rates (see Methods), the untransformed error rates were plotted for illustrative purposes. Error bars reflect 1 SEM.
