摘要：
Converging evidence has proved the attentional bias of Internet addicts (IAs) on network information. However, previous studies have neither explained how characteristics of network information are detected by IAs with priority nor proved whether this advantage is in line with the unconscious and automatic process. To answer the two questions, this study aims to investigate whether IAs prioritize automatic detection of network information from the behavior and cognitive neuroscience aspects. 15 severe IAs and 15 matching healthy controls were selected using Internet Addiction Test (IAT). Dot-probe task with mask was used in the behavioral experiment, while deviant-standard reverse oddball paradigm was used in the event-related potential (ERP) experiment to induce mismatch negativity (MMN). In the dot-probe task, when the probe location appeared on the Internet-related picture's position, the IAs had significantly shorter reaction time than do the controls; in the ERP experiment, when Internet-related picture appeared, MMN was significantly induced in the IAs relative to the controls. Both experiments show that IAs can automatically detect network information.

为探讨相对剥夺感与大学生网络游戏成瘾的关系及其作用机制,在病态网络使用(Pathological Internet Use, PIU)的认知-行为模型视角下,采用经济相对剥夺感问卷、非适应性认知量表、内隐人格观量表和网络游戏成瘾量表,对1008名具有网络游戏使用经验的大学生进行调查。结果表明:(1)在控制性别和年龄的条件下,相对剥夺感能够显著正向预测大学生网络游戏成瘾;(2)相对剥夺感通过非适应性认知的中介作用预测网络游戏成瘾;(3)非适应性认知的中介作用受到内隐人格观的调节。具体来说,相对于持渐变观的大学生,持实体观的大学生的非适应性认知对其网络游戏成瘾的预测作用更大。研究结果有助于揭示大学生网络游戏成瘾的形成机制,对大学生网络游戏成瘾的干预具有一定启示意义。

摘要：
Resonance is generally used as a metaphor to describe the manner how the information from different sources is combined. Although it is an attractive and fundamental phenomenon in human behavior studies, most studies observed semantic resonances in well-controlled experimental settings at word level. To make up the missing link between word and document level resonances, we devoted our contributions to topic resonances in a novel and natural setting: academic commentaries. Ninety-three academic commentaries from ninety-three authors, along with their references and original papers, are analyzed by a latent Dirichlet allocation based natural language processing approach. This approach can decompose a corpus written and read by an author into several topics with different weights, which can reveal the phenomena ignored at word or document level. We found that (1) topic resonances commonly exist between commenters' fundamental input and output topics; (2) output words are re-allocated by commenters to echo salient input topics; (3) commenters are more prone to associate references which focus on the non-dominant input topics; and (4) topic resonance can even be predicted by a Hebbian-like model which matches the aforementioned findings. These findings will continue to enrich our understanding on the relationship among probe, feedback and context.

摘要：
BACKGROUND: The effects of gender, negative life events, and coping on depression have been well-documented. But depression is a heterogeneous syndrome of which the severity ranged from mild depression to major depression. This study aimed to investigate the specific effects of gender, negative life events, and coping on different stages of depression severity. METHOD: A total of 5989 students (aged 16-25 years, M=20.85, SD=0.58), recruited from six universities in the central region of China using the stratified cluster sampling method, completed Life Events Questionnaire, Coping Response Inventory, and Beck Depression Inventory-. RESULTS: Among the participants, 708 (11.8%) students presented different severity levels of depression. Gender, negative life events, positive coping, and negative coping all had significant effects on depression. That is, the possibility of being depressed was significantly higher in female university students, or students who had more negative life events, more negative coping, or positive coping. In terms of the different stages of depression severity, all these factors had significant effects on the stage from non- depression to mild depression; only gender, negative life events and positive coping had significant effects on the stage from mild depression to moderate depression; only gender had a significant effect on the stage from moderate depression to major depression. LIMITATIONS: The causal role of these factors on different stages of depression severity could not be inferred. Moreover, the participants were from a non-clinical population. CONCLUSIONS: The effects of gender, negative life events and coping varied in different stages of depression severity. The effects of life events and coping styles became insignificant with the increasing severity of depression, whereas the effect of gender remained significant. The results could provide guidance for the prevention, intervention, and treatment of depression.
