Abstract:
Adolescence is a critical developmental stage marked by profound physical, emotional, and social transformations. During this stage, bodily changes, emotional vulnerability, environmental stimuli, and cultural influences may expose adolescents to behaviors that appear unpredictable or maladaptive. Moreover, a central aspect of adolescence is the drive for self-affirmation, which often manifests through aggression, in actions, thoughts, and interpersonal relationships. More than merely an individual reaction, adolescent aggression also constitutes a broader social phenomenon. The present work seeks to explore the contemporary role played by aggression in adolescence and its varied expressions. It supports a paradigm in which adolescent aggression fluctuates between two poles: one aligned with the pleasure principle, characterized by self-gratifying behavior that disregards others and seeks unmediated satisfaction; and the other aligned with the reality principle, characterized by self-affirming behavior grounded in moral consciousness and respect for social norms. The dominance of either form of aggression plays a crucial role in shaping adolescent development. In contemporary society, cultural models and myths promote a narcissistically driven, empathy-deficient form of aggression. This mode of behavior, which is socially rewarded and normalized, risks becoming the adolescent's internalized version of the reality principle, with success achieved at the expense of others. Such a framework may inhibit the transformation of aggression into socially and morally attuned behavior. Thus, it is essential to understanding adolescent aggression as a powerful, though ambivalent, force in the human development.
