where steeper curvature reflect greater discounting of delayed rewards \citep{McKerchar2009,Yi2009,Myerson_2001,Myerson_1995,Green_1994,Rachlin_1972}. High rates of delay discounting were found associated with a wide range of behaviors including substance abuse use \cite{Wilson2015,Sheffer2012} , pathological gambling \cite{Alessi_2003} , and overeating\cite{Reimers_2009,Price_2014}. Despite its contribution to our understanding of the maladaptive behaviors in a clinical setting, delay discounting was also found to be an explanatory variable in various decision domain, ranging from academic performance \cite{Olsen_2018,Acuff_2017} to consumptive choice (\cite{Dittmar_2010,Chen_2005}).
