Physiological studies show that reactance-induced stress responses activate the sympathetic nervous system, increasing cortisol levels by 23 percent within minutes of perceived autonomy threats.

Boyle's law demonstrates that capacitive reactance decreases inversely with frequency, halving when frequency doubles according to the formula XC equals 1 divided by 2πfC.
- 04
Electrical reactance, measured in ohms, increases proportionally with frequency in inductive circuits, doubling when frequency doubles according to the formula XL equals 2πfL.
- 03
Reactance effects appear strongest in adolescents aged 13-18, who show increased defiance when autonomy is restricted compared to adults or younger children.
- 02
Reactance theory predicts that direct requests to change behavior often backfire, with smokers told to quit showing increased cigarette consumption compared to control groups.
