网络相关文字刺激和压力对网络成瘾者线索诱发渴求的影响
The Impact of Internet-related Word Stimulus and Stress on Internet Addicts' Cue-induced Craving

渴求感特别是线索诱发渴求是成瘾行为维持和戒断失败的主要原因。本研究通过两个实验分别探讨了网络相关文字刺激和压力对网络成瘾者线索诱发渴求的影响。研究一以25名网络成瘾大学生为被试，以网络相关和中性词语为实验材料，采用线索暴露范式（Cue-reactivity Paradigm）的研究发现，只有网络相关文字刺激能显著诱发网络成瘾者的渴求感。在此基础上，研究二以40名网络成瘾大学生为被试，以公开演讲范式为压力诱发情境，以网络相关词语和中性词语为实验材料，采用线索暴露范式（Cue-reactivity Paradigm）的研究发现，在压力条件下，网络相关文字能诱发网络成瘾者更为强烈的渴求感。本研究深化了对网络成瘾形成维持心理机制的研究，也为网络成瘾的干预矫正提供了思路。
Craving, especially the cue-induced craving not only maintains and exacerbates the addictive behaviors, but also often leads to relapse. Based on existed researches, this study aimed to investigate the effect of Internet-related word stimulus and stress on Internet addicts' cue-induced craving through two experiments. In the first experiment, 25 Internet addicts participated in the Cue-reactivity experiment with Internet-related words and neutral words. The results showed that, only Internet-related words could significantly arouse Internet addicts' cue-induced craving. And in the second experiment, we examined the effect of stress on Internet addicts' cue-induced craving among 40 Internet addicts. Participants' stress was induced by Public speaking paradigm. The results showed that, under the condition of stress, Internet-related words could arouse more intense carving for Internet among Internet addicts. This study might deepen our understanding of the formation and maintenance mechanism of Internet addiction. Also, it provides a way for the intervention of Internet addiction from the perspective of craving.
