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.

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.

This study investigated the role of need satisfaction in adolescent pathological internet use by comparing the differences in the perception of need satisfaction online and offline. A compensatory satisfaction theory was proposed to explain the role of need satisfaction online in pathological internet use. Cross-sectional data were collected from 4559 Chinese students from 12 to 20 years of age. The participants responded to an anonymous questionnaire concerning their internet use behavior, their perceived level of need and their need satisfaction online and offline. The results of structural equation modeling showed that pathological internet use was predicted not by the level of need, but rather by the way in which the need was satisfied. Need satisfaction perceived online predicted adolescent pathological internet use positively, while need satisfaction perceived offline predicted pathological internet use negatively. Furthermore, the direct comparison of need satisfaction online and offline showed that the advantage of need satisfaction online completely mediated the effect of unsatisfied need on adolescent pathological Internet use. Enlightenment of the theory and implications for efforts to encourage offline activities are discussed. © 2015 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.

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.
