The present study aims to investigate children's psychological reactance aroused by their mothers' verbal threats to their behavioral freedoms. Three independent variables were used: threats (attitude-consistent and counter-attitudinal threats), children's grades (second, fouth, sixth, eighth and tenth graders), and their sex (male and female). A 2 x 5 x 2 factorial design was used, and 800 children participated in the present experiment as the subjects. Three types of negative response to verbal threats were measured: affective, verbal and behavioral resistance. The main results were as follows: (1) Counter-attitudinal threat produced greater affective, verbal and behavioral resistance than attitude-consistent threat. (2) The higher the children' s grades become, the greater their affective, verbal and behavioral resistance were. (3) In the second grade the male showed greater affective resistance than the female, but not in other grades. (4) In the eighth and tenth grades the female showed greater verbal resistance than the male, but not in other grades.
