The articles in the present volume enhance the understanding of the role of perceived time in human development. Together, they point to the multifaceted nature of perceived future time and the associations different aspects of time have with goals, preferences, and well-being. Specifically, the articles showcase antecedents and consequences of perceived time left in life, consider ways to optimize measurement of future time horizons, and advance novel questions about the neural correlates of domain-specific aspects of subjective time. Findings are considered within the framework of socioemotional selectivity theory. Future directions for research on time horizons are discussed.
