  "abstract": "The perception that time accelerates with advancing age represents one of the most universally reported yet poorly understood subjective experiences in human cognition. While the physical clock remains invariant, seconds, days, and years retain their objective duration; however, the felt experience of time undergoes profound transformation across the lifespan. This paper synthesizes evidence from multiple disciplines to propose that perceived temporal acceleration emerges from the convergence of five interacting mechanisms: 1) mathematical compression, wherein each successive year represents a diminishing fraction of total lived experience; 2) neurocognitive aging, characterized by reductions in novelty processing, dopaminergic signaling, memory encoding density, and temporal processing efficiency; 3) emotional salience, whereby meaningful events expand in retrospective memory while routine experiences contract; 4) attentional engagement, which modulates real-time temporal awareness; and 5) sociobehavioral stabilization, marked by increasing routine and fewer life transitions across adulthood. We critically evaluate the evidence supporting each mechanism, acknowledge contradictory findings and individual differences, and discuss methodological challenges inherent in studying lifespan changes in temporal experience. Clinical implications are explored across depression, anxiety, and neurodegenerative disorders, with attention to assessment approaches, functional impacts, and intervention strategies. Finally, we identify key priorities for future research, including the need for validated measures of subjective time compression, longitudinal study designs, and translational investigations linking neurobiological mechanisms to lived experience.",
