The Cognitive and Neural Mechanism of the Internet Addiction Effect on Intertemporal Choice
Intertemporal choice refers to the individual weighing of benefits against costs in different time points, and the corresponding judgment and choices (Loewenstein, 1988; Frederick, Loewenstein, & Donoghue, 2002). Intertemporal choice is a very common phenomenon, which covers from minor things like individual’s daily life and economic behavior, to an organization’s or a nation’s public policy making. Therefore, the study of intertemporal choice has great theoretical and practical significance, to help people make more scientific, rational decision. Our research is based on the classic intertemporal choice tasks, by using a scale and an experimental task, to investigate the relationship between Internet addiction and delay discounting in intertemporal choice. Results: 1) Internet addiction test scores and delay discounting rate in intertemporal choice tasks of 33 sub-jects were negatively correlated; at the same time, there were 80 subjects whose Internet addiction test scores and delay discounting rate in intertemporal choice tasks were positively correlated, presenting different characteristics of people; 2) using moderating effect analysis it is found that impulsivity has significant moderating effects on Internet addiction test scores and delay dis-counting rate in intertemporal choice. The results show that, due to the moderation of impulsivity, different groups of people are in different directions on the relationship between Internet addiction and delay discounting rate in intertemporal choice.
