网络游戏中化身参照的加工优势：来自行为与ERPs的证据

采用R/K范式和事件相关电位技术(ERPs)分别从加工结果和加工过程考察网络游戏中化身参照的加工优势。实验1采用R/K范式比较40名玩家在不同参照条件下的记忆成绩。结果发现：化身参照的总再认正确率、R反应再认正确率和辨别力d'都显著优于他人参照, 初步证实化身参照的记忆加工优势。实验2借助ERPs内隐地考察网络游戏中20名玩家的化身参照在加工时间进程上的神经机制。结果发现：加工化身名字比熟悉他人名字诱发更大的P2 (160~260 ms)和P3 (370~600 ms)波幅, 比外国熟悉他人名字的P3潜伏期更短。结果表明, 相比较其他信息, 玩家不仅能够迅速注意到化身相关信息, 还对化身相关信息进行了更加精细和深入地加工。综上所述, 无论是记忆结果还是加工时间进程, 都存在网络游戏中的化身参照加工优势。     

Longitudinal relationships among interpersonal openness trait,hostile attribution bias,and displaced aggressive behaviour: Big Five treated as covariates

Displaced aggressive behaviour is associated with many negative outcomes. Although certain personality traits predict displaced aggressive behaviour, the uniquely longitudinal effect of indigenous interpersonal traits on displaced aggressive behaviour is ignored. To address this gap, we explored the longitudinal relationship among an indigenously interpersonal trait of China (interpersonal openness), hostile attribution bias, and self-reported displaced aggressive behaviour. Additionally, we tested whether hostile attribution bias mediated the relationship between interpersonal openness and self-reported displaced aggressive behaviour. The Interpersonal Self-Support Scale for Undergraduate Students, Word Sentence Association Paradigm for Hostility, Displaced Aggression Questionnaire, and the NEO Personality Inventory-3 were administered to 942 undergraduates on two occasions, 6 months apart. A cross-lagged model showed that, after controlling for the Big Five personality traits, interpersonal openness predicted subsequent hostile attribution bias, and hostile attribution bias predicted self-reported displaced aggressive behaviour 6 months later. Hostile attribution bias at time 2 mediated the relationship between interpersonal openness at time 1 and self-reported displaced aggressive behaviour at time 2. These results were consistent with the interpersonal self-support theory's appraisals of interpersonal openness, and they extended the social information processing and general aggression models to explain displaced aggressive behaviour.     

Discrete‐trial training performance of behavior interventionists with autism spectrum disorder: A systematic replication and extension

Further research is needed on strategies to improve employment outcomes for individuals with autism spectrum disorder (ASD). We replicated and extended prior research by examining the acquisition, maintenance, and generalization of discrete‐trial training (DTT) performance of adults with ASD who were interested in careers as behavior technicians. Three participants received training on how to implement DTT with children and we assessed the maintenance and generalization of DTT performance in the absence of feedback. Results indicated that procedural integrity generalized across children and targets and maintained for 6 to 17 session days without feedback. Results have implications for the successful employment of individuals with ASD as behavior technicians and for future research on strategies to enhance their performance on the job.     

Jeux vidéo violents : leur impact sur la désensibilisation émotionnelle des jeunes

BackgroundThis research aims to evaluate the relationship between the use of violent video games (VVG) and emotional desensitization (ED).MethodTwo hundred and one pupils between the ages of 12 and 16 years completed a questionnaire measuring VVG exposure, empathy and ED.ResultsCorrelations and regression analyses revealed links between exposure to VVG and ED. The VVG experience is a risk factor in the presence of two moderating variables: preexisting empathy and the amount of time spent playing VVG.ConclusionsThe results suggest that exposure to VVG is a risk factor for ED.     

Self-concept as a risky driver: Mediating the relationship between racing video games and on-road driving violations in a community-based sample

PurposeThe mediating relationship of self-conceptions as a risky driver on self-reported driving violations was examined for players of “drive’em up” and “circuit” racing video games using an Internet survey of automobile and racing club members. Structural equation modelling (SEM) tested Fischer et al. (2012) extended socio-cognitive model on the effects of risk-glorifying media on cognitions and actions.MethodAn Internet questionnaire was developed and relied upon validated instruments or questions derived from previous surveys. Driver club members were asked about: (1) their frequency of video game playing, (2) self-perceptions as a risky driver and (3) self-reported driving violations. SEM was performed to examine mediating effects of racing video game playing on self-reported driving violations.ResultsPlaying “drive‘em up” video games positively predicted risky self-concept (β = .15, t = 2.26), which in turn, positively predicted driving violations (β = .73, t = 8.63), while playing “circuit racing” games did not predict risky self-concept, although risky self-concept did predict driving violations (β = .72, t = 8.67).ConclusionsSelf-concept as a risky driver mediated the relationship between racing video game playing and self-reported driving violations for “drive’em up”, but not for “circuit racing” video games. These findings are congruent with Fischer and colleagues’ experimental model that self-concept as a reckless driver mediated the relationship between racing video game playing for “drive’em up”, but not for “circuit racing” games and risk-taking behavior in a video of road traffic scenarios.     

Effects of minimal social cues on trust in the investment game

In anonymous game tasks, individuals’ prosocial behaviour was shown to increase when those individuals were provided with social cues from a third party or bystander. It has been suggested that those social cues can be presented using a configuration suggestive of a face with ‘watching eyes’. This led us to question whether it was possible to provide the watching‐eyes configuration with even weaker facial information, such as a simple dot pattern. By using a minimal social cue paradigm, such as the one described above, the present research found that individuals’ trust toward the trustee increased when they detected the watching‐eyes dot pattern as a source of social cues in two settings: a hypothetical investment game for both college students (Study 1) and customs officers (Study 2); and an actual investment game for college students (Study 3).     

利用游戏log-file预测学生推理能力和数学成绩——机器学习的应用

以360名初中生为被试, 使用推箱子游戏, 结合游戏日志文件(log-file)和机器学习技术预测学生的推理能力和数学成绩。预测变量是从推箱子的过程数据中提取的一系列特征指标, 结果变量是瑞文推理测验成绩和数学成绩, 且均以25%为高低分组的临界值转换为二分变量。结果发现, 训练的模型预测推理能力最高能获得76.11%的查准率、65.72%的精确率、63.10%的查全率以及65.01%的F1得分; 预测数学成绩最高能获得83.07%的查准率、73.70%的精确率、73.33%的查全率以及75.57%的F1得分。研究结果说明, 机器学习建立的区分模型具有较好的预测效果, 利用log-file所记录的游戏过程数据可以对个体的能力进行有效预测。
