The purpose of present study was to investigate what types of mothers' verbal stimulus aroused psychological reactance among their children. Two independent variables were used: situation (real and imaginary situations) and response condition (rejective and acceptive response conditions). Sixth graders (n=1101) were asked to write their mothers' verbal stimulus which aroused them reactance. Results indicated that Command Type of mothers' verbal stimulus facilitated their childrens' reactance and that Reward-Concession Type inhibited it. Methodological advantages of using an imaginary situation were discussed.
