Crucially, this analysis revealed that, overall, the stress group showed marginally greater learning of probability-based information than the control group (as indicated by the marginally significant GROUP × PROBABILITY interaction, F (1, 51) = 3.45, p = .07, η 2 p = .06; stress group: M random high = 96.34%, M random low = 101.61%, standardized learning score: M = 5.27%; control group: M random high = 97.04%, M random low = 100.89%, standardized learning score: M = 3.85%, see Fig 4 ; for a figure with individual data points, see S5 Fig in S1 File ).
