Cognitive Neural Mechanisms of Gain-loss Asymmetry in Intertemporal Choice
Intertemporal choice refers to the tradeoff between costs and benefits at different points in time.The discount rates of intertemporal choice under the gain and loss framework show a significant difference,and the discount rate of losses is usually smaller than that of gains,which is called gain-loss asymmetry.Most of the previous studies focused on the differ-ence of value function in the gain and loss framework and explained gain-loss asymmetry by loss aversion(reflected in neu-ral representations of striatum and vmPFC).In fact,from the perspective of value evaluation,gain-loss asymmetry also comes from the different information processing modes.In addition,difference in the level of cognitive control needs(re-flected in neural representations of dlPFC,ACC,and PPC)and asymmetry in anticipatory feelings(reflected in neural repre-sentations of amygdala and insula)can also explain gain-loss asymmetry.Future studies could explore the neural basis of the gain and loss framework from the perspective of different fields and different combinations of results,combined with sce-nario variables.
