marginally significantp = .081
Analysis of simple slopes of the significant interaction showed that the link between ST values and attitudes towards cooperative methods was positive in the ST condition and the control condition (combined effect, b = 0.17, SE = 0.06, t (116) = 2.93, p = .004, 95% CI [0.06, 0.29], η 2 = 0.07), but negative and marginally significant in the SE condition ( b = −0.16, SE = 0.09, t (116) = −1.76, p = .081, 95% CI [− 0.35, 0.02], η 2 = 0.03).
