Significant moderation effect of inhibitory control on older adults’ choices behavior (mean inhibitory control – 1 standard deviation vs. mean inhibitory control vs. mean inhibitory control + 1 standard deviation). Here, the y-axis corresponds to the four choice options reflecting the extent to which the alternative offer is preferred (1 = strong no, 2 = weak no, 3 = weak yes, 4 = strong yes). Note. Significant interaction of €self x €other x inhibition ability. Note that we split up the sample in low vs. medium vs. high inhibitory control for illustration purposes only. Inhibition ability entered the model as a continuous predictor. In older adults with high inhibition abilities (right panel, mean inhibitory control + 1 SD), choices to accept the proposed offer were impacted by a multiplicative effect of both €self and €other. In older adults with medium inhibition abilities (middle panel, mean inhibitory control), choices to accept the proposed offer were impacted by values for €self and €other, but not by the interaction of €self x €other. Older adults with low inhibition abilities (left panel) were only influenced by the values for self (€self). The shaded areas around the lines represent the 95% confidence intervals. SD = standard deviation, OA = older adults.
