Abstract:
Objective:To examine the information processing patterns of college students with high and low procrastination in intertemporal decision-making.Methods:A total of 29 high procrastination college students[Irra-tional Procrastination Scale(IPS)score＞27]and 29 low procrastination college students(IPS score≤27)were recruitted.A 2(group:high/low procrastination)×2(amount:￥100,￥1 000)×5(delay:10/30/90/180/360 days)mixed experimental design was employed.Behavioral measures(delay discounting rates,Payne index)and eye-tracking measures(option/dimension fixation time ratios)were collected.Results:The delay discounting rate had the main effects of group,amount and delay(F=6.62,25.38,121.31,Ps＜0.05).The delay discounting rates were higher in the high procrastination group than in the low procrastination group.The delay discounting rates were higher for a amount of 1 000 yuan than 100 yuan.The delay discounting rate was the highest when the delay was 10 days.The option fixation time ratios were higher in the high procrastination group than in the low procrastination group(P＜0.01),and there were interaction effects between group and amount and between group and delay(F=5.67,2.52,Ps＜0.05).The dimension fixation time ratios were lower for a amount of 1 000 yuan than 100 yuan(P＜0.01).Conclusion:College students with high procrastination exhibit a higher delay discounting rate and stronger attentional bias toward immediate options during intertemporal decision-making.However,both groups pri-oritized the monetary dimension in their information processing strategies.
