Within each estimated level of reactance, different number superscripts indicate significant pairwise differences across the required, freedom, and control for choice freedom conditions, and different letter superscripts indicate significant pairwise differences between the two levels of norms.
Intentions were measured on a 1–5 scale, where 1 = extremely unlikely, 2 = somewhat unlikely, 3 = neither likely nor unlikely, 4 = somewhat likely, and 5 = extremely likely.
