Aggressiveness is a research area that examines the causes, consequences, and manifestations of aggressive behavior in individuals. This research seeks to understand the underlying factors that contribute to aggressive tendencies, as well as how aggression is expressed and the impact it has on the individual and those around them. Researchers may investigate various forms of aggression, such as physical violence, verbal hostility, or relational aggression, and explore how these behaviors are influenced by biological, psychological, and social factors. Additionally, research in this area may aim to develop interventions and strategies for reducing aggressive behavior and promoting healthier ways of coping with conflict and frustration.
