Motoric inhibition and execution modify items’ valuation
ABM
A decrease in the valuation of items associated with response inhibition is the most robust effect found in food-ECTs, even after a single twenty-minute sessionThe increase in the healthy items’ valuation (11% in the experimental vs. 4% in the control intervention) was smaller than the decrease in the unhealthy items’ valuation. We interpret this pattern as following from a ceiling effect instead of a smaller impact of the training on the items associated with response execution than inhibition. Indeed, the healthy (Go) items were highly liked by the participants from the start (baseline mean = 0.62, sd = 0.19), and thus had little room to increase, in contrast to the unhealthy items’ ratings which were also highly liked and could thus decrease more (baseline mean = 0.75, sd = 0.11). Of note, this pattern replicates the increase in valuation seen in the ABM literature
