延时折扣范式下大学生课堂媒体多任务现象的行为经济分析

A behavioral Economic Analysis of College Students’ Media Multitasking in the Classroom Under the Delay Discounting Paradigm

为探讨中国大学生课堂媒体多任务行为背后的冲动性机制,采用由经典延时折扣范式改编的课堂假想情景实验考察了101名大学生的课堂发消息行为。拟合分析结果表明大学生课堂发消息行为本质上是一种在即时少量报酬和延迟丰厚报酬间权衡时做出的冲动性的选择。进一步采用曲线下面积辅助分析发现女生比男生更少进行课堂发消息行为,而且女生在有趣课堂中比在枯燥课堂中更少进行课堂发消息行为。文章提供了对于中国大学生课堂媒体多任务行为的行为经济学分析思路。

In order to investigate the impulsive mechanism behind Chinese college students*media multitasking behaviors in the classroom,the present study explored 101 college students*texting behaviors by using a hypothetical classroom scenario adapted from the classic delay discounting paradigm.The results of curve fitting analysis show that the college students'message-sending behaviors in the classroom is fundamentally an impulsive choice made in the trade-off between the immediate small reward and the delayed lucrative reward.Furthermore,under this mechanism,we used the area under the curve to further explore the influence of classroom interest degree and gender on college students'message-sending behavior in the classroom.The results show that the female participants had lower rates of discounting than the male participants,and the rates of discounting of female participants were lower in the interesting classroom.
