The Bioecological environment is understood as something far beyond the immediate situation that directly affects the developing person - the objects he responds to or the people he directly interacts with in the novel The Perks of Being a Wallflower (1999).
This research examined the identification of bioecological systems and the role of proximal processes (PPCT) in the development of the main character. The objective is analysed how these systems and processes represented in relation to Charlie’s development, drawing on Urie Bronfenbrenner’s theory and the concept of Proximal Process. The final project adopted a qualitative approach, with the primary data taken from Stephen Chbosky’s novel The Perks of Being a Wallflower.
The study shows that the surrounding social environment, including the microsystem (family and peers), mesosystem (interactions between family and peers), exosystem (family members' mental state), macrosystem (cultural values and norms), and chronosystem (the character's past experiences), affects Charlie's development. The proximal process is reflected in Charlie’s personal characteristics, such as being curious yet withdrawn due to parenting patterns, and later shaped by supportive peer relationships that encourage social exploration, including smoking and romantic interactions. Context is observed through the roles of family, school, neighbourhood, and broader societal influences that affect Charlie’s emotional well-being and growth. Time, as a developmental factor, is illustrated by the long-term effects of past abuse that continue to shape Charlie’s relationships and coping strategies
