Abstract: Executive function deficits are one of the causes of the onset, maintenance, and recurrence of internet addiction. Previous studies focused on the impairment of executive function components such as attentional control and response inhibition in internet addicts; however, the status of memory suppression in internet addicts is unclear. This study aimed to explore the characteristics of memory suppression and the mechanism of the retrieval-induced forgetting (RIF) by testing the RIF of college students with internet addiction. The results showed that individuals with low internet addiction yielded a significant RIF in the condition of high-item competition intensity rather than the low-item competition intensity condition. In contrast, individuals with high internet addiction yielded a significant RIF in the condition of low-item competition intensity, but not under the high-item competition intensity condition. These results indicate that the memory suppression ability of college students with internet addiction is seriously impaired; and the RIF is affected by the correlated costs and benefits problem (CCB), which causes interference-based RIF under low-item competition intensity condition.

Key words: internet addiction, retrieval-induced forgetting, item competition intensity, the correlated costs and benefits problem, memory suppression

摘要: 执行功能缺陷是网络成瘾发生、维持和复发的原因之一,以往研究侧重于探讨网络成瘾者注意控制、反应抑制等执行功能成分的损伤状况,而其记忆抑制状况尚不清楚。本研究通过考察网络成瘾大学生的提取诱发遗忘(RIF)来探讨其记忆抑制的特点及RIF的产生机制。结果发现:低网络成瘾个体在高项目竞争强度下表现出显著的RIF,在低项目竞争强度下未产生;高网络成瘾个体在低项目竞争强度下表现出显著的RIF,在高项目竞争强度下未产生。结果表明网络成瘾大学生的记忆抑制能力受损严重,其在低项目竞争强度下易受相关代价与效益问题(CCB)影响而产生干扰性RIF。
