摘　　要：基于"大学生互联网使用动机量表"和"大学生病理性互联网使用行为量表"的测量结果,采用匹配法筛选出21名基于人际情感性动机的病理性网络用户和22名非人际情感性动机的健康性网络用户,对其实施延迟折扣任务(DDT)、stop-signal任务和Stroop色词命名任务,探讨了基于人际情感性动机的病理性网络用户的冲动控制特性。结果发现,相对于健康性网络用户,病理性网络用户对延迟强化物的折扣速度更快,但后者的反应抑制失败率、反应抑制潜伏期(SSRT)和冲突抑制功能均与前者无显著差异。这些结果表明,病理性网络用户的冲动控制障碍主要表现为以对即时强化的超敏感性和强化物长远价值的非敏感性为特征的"短视"倾向,而非行为抑制功能的缺失。To explore impulse control characteristics in social-affective motives-based pathological Internet users, 21 social-affective motives-based pathological Internet users and 22 normal Internet users who were selected by The Internet Use Motives Scale and the Pathological Internet Use Behavior Scale for Undergraduates were administered the Chinese computerized versions of the DDT based on hypothetical monetary rewards, stopsignal task and Stroop color-word naming task. The results showed that the delay-discounting rates （k）of pathological Internet users in DDT were much higher than those of normal controls, however, the failure ratio of response inhibition and SSRT in the top-signal task and the interference effect in Stroop color-word naming task were consistent between the two groups. From the present study, we conclude that the impulse control disorder in social-affective motives-based pathological Intemet users is manifested in their hyposensitivity to immediate rewards and their insensitivity to delayed value in delayed reinforcement situations, which leads to a quick decay of long-time value, but not an impairment of behavioral inhibition function.
