<p>Adolescence is a critical developmental period marked by significant social, emotional, and cognitive changes that profoundly impact trust. This paper examines how these developmental processes influence youth trust, as distinct from, and as an antecedent of, adult trust. Adolescence is characterized by significant brain maturation that influences social cognition, emotional regulation, and peer interactions, making it a key period for social trust development. Youth process social information differently than adults, becoming increasingly sensitive to social rewards and peer influence, while parental socialization also shapes youth trust through explicit teachings and implicit behavioral cues. The behaviors and attitudes established during adolescence have lasting impacts on adulthood, such that understanding youth trust has theoretical, practical, and methodological implications for our understanding of trust in adulthood. Current trust theories and methodologies may not fully capture the unique social dynamics of adolescent trust, suggesting the need for more ecologically valid and interdisciplinary research approaches. By integrating insights from neuroscience and psychology, this paper aims to enrich the understanding of youth trust dynamics in youth, underscoring the importance of considering adolescence as a distinct developmental phase in trust research. Ultimately, the paper advocates for a developmental lens in trust research.</p>
