A Longitudinal Assessment of Trait Argumentativeness and Verbal Aggressiveness between Seventh and Eighth Grades.

Finds no significant differences between measures of general tendency to argue taken immediately after a one-week training program on "Arguing Constructively" and measures obtained 7 months to 1 year later. Finds, however, that students' self-reported levels of verbal aggressiveness were significantly higher 7 months to 1 year later than immediately following the training. (SR)
