Scarcity goods have generally been perceived as high in value real-world and empirical studies. However, few studies investigated this over time, such performance intertemporal decision making. This study’s chief objective was to determine how scarcity evaluation changes temporally. We used the electroencephalogram technique an outcome task with valuation of ordinary rewards delivered at different times explore effect on delay discounting. The feedback-related negativity (FRN) results show that were associated a more negative amplitude than goods, future evoked deflection compared those immediately. prominent FRN derived mainly from trials rather immediate condition only condition. Frontal Asymmetry Index (FAI) greater relative left frontal cortical activity when asymmetry indicated approach motivation. Our electrophysiology data indicate value, particularly
