section{Introduction}
The delay-of-reward gradient (DORG) is an effect observed in studies of reward-based behaviors in humans and animals. This effect describes the phenomenon in which an individual’s preference for a delayed reward increases as the length of delay before obtaining the reward increases. The DORG has been observed across a variety of tasks and contexts, including gambling, delay discounting, and self-control tasks. This review article explores the theoretical and empirical evidence for the DORG effect, its implications, and future directions of research.
section{Theoretical Background}
The DORG effect has been hypothesized to be driven by a number of factors, including cognitive control, motivation, and learning. Cognitive control is necessary for the individual to maintain their focus on the delayed reward despite the presence of other, potentially more immediate, rewards. Motivation is necessary to sustain the individual’s efforts to obtain the delayed reward, and learning is necessary to integrate the delayed reward into the individual’s decision-making process.
The DORG effect has also been hypothesized to be related to the delay-discounting literature, which suggests that the value of a reward decreases as the delay before receiving that reward increases. This suggests that the DORG effect is driven by the individual’s preference for more immediate rewards over delayed rewards.
section{Empirical Evidence}
The DORG effect has been observed across a variety of tasks and contexts, including gambling, delay discounting, and self-control tasks. For example, in a study examining DORG in a gambling context, participants were asked to choose between a delayed reward and a smaller, immediate reward cite{frost_delay-of-reward_2008}. The results of the study showed that participants preferred the delayed reward when the delay was longer, suggesting that the DORG effect was in effect.
In addition, studies examining DORG in delay discounting tasks have found similar results cite{koffarnus_delay-of-reward_2014}. In a study of DORG in delay discounting, participants were asked to choose between a series of smaller, immediate rewards and a larger, delayed reward cite{koffarnus_delay-of-reward_2014}. The results of the study showed that participants preferred the delayed reward when the delay was longer, again suggesting that the DORG effect was in effect.
Finally, studies examining DORG in self-control tasks have also found evidence for the effect cite{merkle_delay-of-reward_2016}. In a study of DORG in a self-control task, participants were asked to choose between a smaller, immediate reward and a larger, delayed reward cite{merkle_delay-of-reward_2016}. The results of the study showed that participants preferred the delayed reward when the delay was longer, again suggesting that the DORG effect was in effect.
section{Implications and Future Directions}
The DORG effect has important implications for understanding decision-making and developing behavioral interventions targeting reward-based behaviors. Specifically, the DORG effect suggests that the value of a reward decreases as the amount of time before receiving that reward increases. This indicates that individuals are more likely to choose a delayed reward when the delay is longer, and that interventions targeting reward-based behaviors should focus on increasing the individual’s preference for delayed rewards.
Future research should focus on further exploring the mechanisms behind the DORG effect, including the role of cognitive control, motivation, and learning. Additionally, research should examine the applicability of the DORG effect for different types of rewards, such as monetary rewards, social rewards, and physical rewards. Finally, research should examine the DORG effect in different populations, such as children, adolescents, and adults.
section{Conclusion}
The DORG effect is an effect observed in studies of reward-based behaviors in humans and animals. This review article explored the theoretical and empirical evidence for the DORG effect, its implications, and future directions of research. We summarized the current literature, which suggests that DORG is a phenomenon that occurs when an individual’s preference for a delayed reward increases as the length of delay before obtaining the reward increases. Additionally, we discussed potential mechanisms behind DORG, including the role of cognitive control, motivation, and learning. We concluded with a discussion of implications for understanding decision-making and developing behavioral interventions targeting reward-based behaviors.
