Adolescence is a critical developmental phase characterized by profound biological, psychological, emotional, and social transformations. These changes do not occur uniformly but are shaped by age, gender, and sociocultural contexts. The present research article explores gender-based differences between early and late adolescents, focusing on emotional regulation, cognitive development, academic motivation, self-concept, peer relationships, and risk-taking behaviors. Drawing on developmental psychology and gender studies, the study highlights how gender differences manifest differently across stages of adolescence rather than remaining static. The analysis demonstrates that early adolescence is marked by heightened emotional vulnerability, particularly among females, whereas late adolescence shows increased autonomy and risk-taking tendencies, especially among males. However, the findings also reveal narrowing gender gaps in several domains, suggesting evolving gender roles and social expectations. The article underscores the importance of stage-specific and gender-sensitive interventions in educational and mental health contexts and contributes to a more nuanced understanding of adolescent development.
