Impulsive individuals perceive time as more costly, leading them to overestimate durations and devalue delayed rewards. This study explores the theoretical link between altered time perception and impulsivity.

Area of Science:

Cognitive Psychology
Neuroeconomics
Decision Science

Background:

Time is a critical factor in decision-making, with subjective time perception influencing the valuation of delayed rewards.
Existing literature presents an unclear relationship between impulsivity and time perception, necessitating a stronger theoretical framework.

Purpose of the Study:

To develop a theoretical foundation for understanding the association between altered time perception and impulsivity.
To propose that impulsive individuals experience time with a higher subjective cost, impacting their decision-making processes.

Main Methods:

Theoretical development integrating concepts of time perception and impulsivity.
Analysis of existing literature to identify gaps and propose a new conceptual model.

Related Experiment Videos

Main Results:

Impulsive individuals are hypothesized to overestimate time intervals due to a heightened perception of time's cost.
This overestimation leads to stronger discounting of delayed rewards compared to self-controlled individuals.

Conclusions:

An altered sense of time, specifically overestimation of duration, is proposed as a key mechanism underlying impulsivity.
Further empirical research is needed to validate the proposed theoretical link between subjective time perception and impulsive behavior.
