The present study aims to investigate children's psychological reactance aroused by teacher's verbal threats to their behavioral freedoms. Three independent variables were used: threats (attitude-consistent and counter-attitudinal threats), children's grades (forth, sixth, and eighth graders), and their gender (male and female). A 2 X 3 X 2 factorial design was used, and 180 children participated as subjects. Three types of negative response to verbal threats (affective, verbal, behavioral reactance) were measured by both open-ended questions and a rating scale method. The main results were as follows: (1) Counter-attitudinal threat produced greater affective reactance as measured by a rating scale and greater verbal reactance measured as by open-ended questions than did attitude-consistent threat. (2) Children's affective, verbal, and behavioral reactance increased with grade level.
