Changes in the control group's liking did not differ across the two phases (rest phase: mean change 0.27±1.89, experiment phase: mean change 0.31±1.36; paired t =0.24; P =0.81) but was large and highly significant for the intervention group (rest phase: mean change 0.39±1.61, experiment phase: mean change 2.81±2.50; paired t =9.94; P <0.001).
