摘要：

目的:对四种延迟贴现模型(两个单参数贴现模型:指数衰减模型和双曲线模型;两个双参数模型:类双曲线模型和幂函数模型)进行比较,选择最优模型用于贴现数据拟合。方法:分别用四种贴现模型对61名青少年被试的延迟贴现数据进行拟合,比较它们在群组水平和个体水平的拟合情况。结果:1无论是在群组水平还是在个体水平,双参数模型对贴现数据拟合的有效性、适配性均优于单参数贴现模型;2两双参数模型的参数s均显著小于1,其增加合理。结论:双参数模型优于单参数模型。

Objective:The present study compared four discounting models(two one-parameter models: the exponential decay model and the hyperbola model, and two two-parameter models: the hyperboloid-like model and the power exponen tial function model) in order to select an optimal fitting discounting model. Methods:The delay discounting data of sixtyone adolescents were fitting separately into the four discounting models, and the fitting indexes in the four models were com pared at both group and individual levels. Results:①Two-parameter models were more better-fitting than one-parameter models both on data fitting validity and parameter estimates. ②The parameter s of both two-parameter models were signifi cantly less than 1.0, and its increase was reasonable. Conclusion: Two-parameter models provides more-to-excellent fits than one-parameter models for the delay discounting.
