The article integrates socio-cognitive and psychodynamic models to explore the cognitive processes and defense mechanisms that influence aggressive reactions. Socio-cognitive models, such as the Social Information Processing (SIP) model, General Aggression Model (GAM), and Integrative Cognitive Model (ICM), focus on how individuals process social information and the role of cognitive control processes in inhibiting aggressive impulses. Psychodynamic models, including Freud's drive theory, Klein's object relations theory, and Kohut's psychology of the self, emphasize the unconscious psychological processes and defense mechanisms (DMs) that mediate aggressive behavior. The study conducted an empirical analysis using the Hostile Expectancy Violation Paradigm (HEVP) and Stop Signal Task (SST) to assess the relationship between reactive aggression, hostile attribution bias (HIA), response inhibition, and DMs. Results showed that reactive aggression and HIA were not significantly correlated with response inhibition but were positively and negatively correlated with image distorting and adaptive defense styles, respectively. The article highlights the importance of integrating socio-cognitive and psychodynamic models to better understand the complex psychological processes underlying aggressive behavior.The article integrates socio-cognitive and psychodynamic models to explore the cognitive processes and defense mechanisms that influence aggressive reactions.
