Background: Although the independent effects of childhood adversities and of recent negative events on suicidality have been well-documented, the combinative role of childhood and recent adversities on risk for suicidality is still underexplored, especially in the context of Chinese culture and in consideration of specific types of negative events. Method: 5989 students, randomly sampled from six universities in central China, completed the online survey for this study. Suicidal behavior, life adversity during childhood and stressful events in recent school life were assessed with designed questionnaires. Results: Students experiencing recent stressful life events more often reported an experience of life adversity during childhood. While recent stressful life events and childhood life adversity both were associated with an increased risk for suicidal behavior, the two exposures presented conjunctively and acted interactively to increase the risk. There was noticeable variation of effects associated with specific childhood life adversities, and sexual abuse, poor parental relationship, divorce of parents and loss of a parent were among the adversities associated with the highest increased risk. Recent conflicts with classmates, poor school performance and rupture of romantic relationships were the recent school life stressors associated with the highest increased risk. Conclusions: Childhood adversity and recent school life stressors had a combinative role in predicting suicidality of young people studying in Chinese colleges. Unhappy family life during childhood and recent interpersonal conflicts in school were the most important predictors of suicidality in this population. © 2014 You et al.

Objective: Internet addiction is one of the most common problems among adolescents and effective treatment is needed. This research aims to test the effectiveness and underlying mechanism of multi-family group therapy (MFGT) to reduce Internet addiction among adolescents. Method: A total of 92 participants consisting of 46 adolescents with Internet addiction, aged 12-18. years, and 46 their parents, aged 35-46. years, were assigned to the experimental group (six-session MFGT intervention) or a waiting-list control. Structured questionnaires were administered at pre-intervention (T1), post-intervention (T2) and a three-month follow-up (T3). Results: There was a significant difference in the decline both in the average score and proportion of adolescents with Internet addiction in MFGT group at post-intervention (MT1=3.40, MT2=2.46, p<0.001; 100 versus 4.8%, p<0.001) maintained for three months (MT3=2.06, p<0.001; 100 versus 11.1%, p<0.001). Reports from both adolescents and parents were significantly better than those in the control group. Further explorations of the underlying mechanisms of effectiveness based on the changed values of measured variables showed that the improvement in adolescent Internet use was partially explained by the satisfaction of their psychological needs and improved parent-adolescent communication and closeness. Conclusions: The six-session multi-family group therapy was effective in reducing Internet addiction behaviors among adolescents and could be implemented as part of routine primary care clinic services in similar populations. As family support system is critical in maintaining the intervention effect, fostering positive parent-adolescent interaction and addressing adolescents' psychological needs should be included in preventive programs for Internet addiction in the future. © 2014 Elsevier Ltd.

Internet gaming addiction (IGA) is an increasing mental health issue worldwide. Previous studies have revealed decision-making impairments in excessive Internet gamers (EIGs) with high symptoms of IGA. However, the role of feedback processing in decision-making deficits among EIGs remains unknown. The present study aimed to investigate the effect of feedback processing on decision-making deficits under risk among EIGs, using the Game of Dice Task (GDT) and a modified version of the GDT in which no feedback was provided. Twenty-six EIGs and 26 matched occasional Internet gamers (OIGs) were recruited. The results showed: (a) OIGs performed better on the original GDT than on the modified GDT (no feedback condition); however, EIGs performed similarly on both tasks; (b) EIGs and OIGs performed equally on the modified GDT; however, EIGs chose more disadvantageous options than OIGs on the original GDT; (c) EIGs utilized feedback less frequently on the original GDT relative to OIGs. These results suggest that EIGs are not able to utilize feedback to optimize their decisions, which could underlie their poor decision-making under risk. © 2014 Elsevier Ireland Ltd.

Objectives: To examine predictive power of psychache and life satisfaction on risks for suicidal ideation and suicide attempt among young people. Design: A cross-sectional study. Setting: Data were collected from an online survey in Wuhan, China. Participants: 5988 university students from six universities were selected by a stratified cluster sampling method. Primary and secondary outcome measures: Suicidal ideation and suicide attempt at some point of the students' lifetime were the outcomes of interest. Results: Students with suicidal ideation or attempted suicide reported a lower level of life satisfaction and high degree of psychache than counterparts without suicidal ideation or attempt. Regression analyses indicated that life satisfaction and psychache were significantly associated with the risk of suicidal ideation and the risk of suicidal attempt. Though psychache showed a relatively stronger predictive power than life satisfaction, the effect of the two factors remained significant when they were individually adjusted for personal demographic characteristics. However, when the two factors were included in the model simultaneously to adjust for each other, psychache could fully explain the association between life satisfaction and suicidal attempt. Life satisfaction remained to contribute unique variance in the statistical prediction of suicidal ideation. Conclusions: Psychache and life satisfaction both have a significant predictive power on risk for suicidal behaviour, and life satisfaction could relieve the predictive power of psychache when suicidal behaviour is just starting. Shneidman's theory that psychache is the pre-eminent psychological cause of suicide is perhaps applicable only to a more serious form of suicidal behaviour.

Data were collected from 3556 Chinese junior and senior high school students to explore the associations between adolescent pathological Internet use (PIU) and parental variables, including parent-adolescent communication, parental Internet use and parental Internet-specific norms regarding adolescent Internet use. In particular, this study considered the different role of parental variables under two conditions: parental norms that were consistent or inconsistent with parents' Internet use behaviors. The participants were asked to answer an anonymous questionnaire that included all mentioned factors. The results revealed an 11% rate of adolescent PIU, and hierarchical multiple regressions indicated that parent-adolescent communication predicted PIU negatively under both conditions. When parental norms were consistent with their Internet use behaviors, parental norms predicted adolescent PIU negatively; conversely, when parental norms were inconsistent with their Internet use behaviors, parental behaviors predicted adolescent PIU positively. Implications for family-based prevention and the limitations of this study are discussed. © 2012 Elsevier Ltd. All rights reserved.

A growing body of evidence suggested that elapsing time is tightly associated with space in a specific way (e.g., Spatial Temporal Association of Response Codes or STARC effect). However, existing findings cannot justify a hypothesis that elapsing time is recoded directly into a spatial linear representation in working memory. The present study addresses this fundamental question by using three modified STARC-related working memory paradigms. In different experiments, participants were asked to give order judgment, order-irrelevant STM recognition judgment, or motor-related free-choice judgment, immediately after successive presentation of a set of disparate stimuli. Results show that responses to early stimuli were faster or more often with the left key and responses to late stimuli were faster or more often with the right key. These findings clearly support the hypothesis that elapsing time is directly and automatically recoded into a spatial linear representation in working memory. © 2014 Hogrefe Publishing.

Mobile phone is popular among residents in rural areas of China, especially among the adolescents. The aim of the present research was to investigate how the attitude towards mobile phone as a social status symbol affected life satisfaction of adolescents living in rural areas of China. Teacher-student relationship and student-student relationship as important interpersonal relationship indicators of adolescents were included as mediator variables. Participants were 656 adolescents (316 girls, Mage = 14.43 ± 1.67 years), and they were surveyed on the attitude towards mobile phone as a social status symbol, teacher-student relationship, student-student relationship, and life satisfaction in the present research. Results showed that the attitude towards mobile phone as a social status symbol reduced life satisfaction. What's more, attitude towards mobile phone as a social status symbol could reduce life satisfaction via teacher-student relationship, as well as via teacher-student relationship and student-student relationship in sequence. We concluded that the attitude towards mobile phone as a social status symbol is a new risk factor of adolescents' development. © 2016 Elsevier Ltd

Environment condition has been shown to play an important role in brain development. The present study examined the effects of enriched and impoverished environment on both spatial and emotional learning and memory of young mice and explored the underlying mechanisms. 3-week-old mice were housed in enriched environment (n=10, 10 mice in a large cage with toys and a running wheel), or standard environment (n=10, 10 mice in a large cage without objects), or impoverished environment (n=10, single mice in a small cage without objects) for 6. weeks. Then, the spatial and emotional cognition of mice were evaluated by the water maze and step-down inhibitory avoidance test, respectively. To explore the underlying mechanisms, oxidation measurement in hippocampus and medial-temporal lobe cortex (MTLC) and apoptosis examination in hippocampus were performed. Results showed that compared with standard environment group, enriched and impoverished mice exhibited high and low performance levels in behavior tests, respectively. The oxidative status of hippocampus and MTLC were decreased in enriched group but increased in impoverished group. Moreover, changes in apoptosis of hippocampus in these two groups showed the same tendency with oxidative status. These results suggest that environment condition can simultaneously influence spatial and emotional learning and memory, which may result from inducing changes in the oxidative and apoptosis status in associated brain regions. Here, we firstly report using young mice to examine the oxidative status as a primary and direct factor to explore the mechanism of effects of different environment on both spatial and emotional cognition. © 2012 The Japanese Society of Child Neurology.

ERPs were elicited to (1) words, (2) pseudowords derived from these words, and (3) nonwords with no lexical neighbors, in a task involving listening to immediately repeated auditory stimuli. There was a significant early (P200) effect of phonotactic probability in the first auditory presentation, which discriminated words and pseudowords from nonwords; and a significant somewhat later (N400) effect of lexicality, which discriminated words from pseudowords and nonwords. There was no reliable effect of lexicality in the ERPs to the second auditory presentation. We conclude that early sublexical phonological processing differed according to phonotactic probability of the stimuli, and that lexically-based redintegration occurred for words but did not occur for pseudowords or nonwords. Thus, in online word recognition and immediate retrieval, phonological and/or sublexical processing plays a more important role than lexical level redintegration. © 2014 Cheng et al.
