Verbal aggressiveness functions as a catalyst for physical aggressiveness (Infante & Wigley, 1986; Infante et al., 1989; Sabourin et al., 1993). The negative effects of verbal aggressiveness may be more devastating and by physical aggression because its effects last for our entire life (Infante, 1995). The majority of research shows that the verbal aggressiveness is considered destructive feature (Infante, 1995; Myers & Rocca, 2000; Bekiari, Kokaridas & Sakellariou, 2006; Myers et al., 2007; Bekiari, 2012; 2014; …show more content…
