Comparing intertemporal decision-making models: Predictions and applications in lifespan through subjective time perception.

ABSTRACT: Intertemporal decision-making is essential in daily life, requiring individuals to evaluate the value of investments over time. This study aimed to assess how well intertemporal choice models explain and predict decision-making behaviours, focusing on subjective time perception across the lifespan. Five models were compared: two basic models (hyperbolic and exponential discounting) and three based on psychophysical principles of time perception (Stevens' power law exponential, Weber-Fechner exponential and Stevens' power law hyperbolic discounting). Using three datasets, this study identified which model better describes delay discounting and measured each model's predictive accuracy through cross-validation across the lifespan. Findings revealed that Stevens' power law exponential and hyp
