网络欺负中的旁观者行为

网络欺负中的旁观者是指“目击网络欺负事件的个体”。旁观者目击欺负后的行为反应可以分为：亲社会行为和反社会行为。影响旁观者行为的因素有旁观者的个人特质(冲动性、外向性和开放性)、旁观者的心理因素(同理心、自我效能感、社会支持和孤独感)、受欺负个体的自我表露程度和生态环境中的关系等。旁观者效应、道德脱离和旁观者干预模型可以对旁观者目击网络欺负事件后的反应进行解释。未来可以从具身认知、脑神经机制、跨文化和网络环境塑造等方面作出进一步探索。     

社会信念的自信判断:自我一致性模型的验证

采用重复测验的自信判断范式,检验自我一致性模型。项目一致性与项目共识性的分析表明:被试从大量共享的信念总体中抽取样本进行正误判断,自信判断则基于各个样本信念的一致性,并反映新样本做相同判断的可能性;建立在代表性样本上的判断有更高的一致性或共识性,信念建构的反应时更短且自信更高;项目一致性与项目共识性存在交互关系:高一致性的判断也是高共识性的判断。结果验证了自我一致性模型在中国文化背景下的存在。     

Alcohol interlocks and prevention of drunk-driving recidivism

IntroductionAlcohol interlock programs (AIP) are aimed at preventing drunk-driving recidivism. They first appeared in Europe in the nineties.ObjectivesThe purpose of this study was investigate whether AIPs are effective in reducing recidivism and determine what factors of such programs contribute to their positive impact.MethodWe performed a follow-up of AIP participants (n = 175) and control participants (n = 234) for five years. Data such as blood alcohol concentration (BAC) at time of arrest, previous and subsequent violations (alcohol-related or other types) were collected from the official driver's license files. For self-evaluation and evaluation of the program (since November 2009 only), we used questionnaires based on two theoretical models: the Transtheoretical Model of Change (Prochaska & DiClemente, 1984) and the Diamond of Change Model from the DRUID project, build to explain which are the elements of driver rehabilitation training courses that favor behavioral modification (Bukasa et al., 2009).ResultsThe data obtained allowed us to describe these populations of alcohol-drinking offenders, for both the interlock program group and the control group. Two salient features were male proneness to alcohol-related violations and a very high BAC (between 1.5 and 2 g/l) among the majority of drivers who drink under the influence of alcohol. In terms of recidivism reduction, the interlock program was not clearly linked to a beneficial effect. An analysis of behavioral change among the AIP participants showed that consciousness raising took effect more quickly than did environmental reevaluation or reinforcement management.ConclusionsThe application of Prochaska et al.’s model to the follow-up of AIP programs would be more fruitful in the future if psychologists are involved in the program. As we have seen, medical/psychological monitoring may not have been strong enough in the program studied here.     

The role of media and peer influences in Australian women's attitudes towards cosmetic surgery

The study aimed to examine the influence of media and peers on attitudes towards cosmetic surgery using a sociocultural framework. A sample of 351 Australian women aged 18–69 years completed measures of media exposure, friend conversations, internalisation of appearance ideals, appearance comparison, body dissatisfaction, and attitudes towards cosmetic surgery. Correlational analysis showed that almost all media and friend variables were significantly correlated with positive attitudes towards cosmetic surgery. A structural equation model based on the sociocultural model showed a good level of fit to the data. The effects of media exposure and friend conversations on body dissatisfaction and attitudes towards cosmetic surgery were mediated by internalisation. We concluded that media exposure and friend conversations affected attitudes towards cosmetic surgery both directly and indirectly. Our results contribute to the understanding of the sociocultural mechanisms underlying women's motivations for cosmetic surgery.     

K-means、潜在类别模型和混合Rasch模型的比较

基于模拟研究比较了K-means方法、潜在类别模型和混合Rasch模型在二分外显变量情境下的聚类效果.结果表明：（1）潜在类别数量、变量数量、样本量、样本平衡和变量间相关对K-means方法、潜在类别模型和混合Rasch模型的分类准确性均有影响且因素间的交互作用存在;（2）除了在2个潜在类别的样本不平衡条件下K-means方法表现较差外,在其他条件下与潜在类别模型和混合Rasch模型的表现相当;（3）混合Rasch模型的分类一致性在2个潜在类别的情境下要好于潜在类别模型,但是在4个潜在类别的情境下要差于潜在类别模型.     

暴力电子游戏对攻击行为的影响及其争论

以Anderson为核心的研究者通过数十年研究发现, 暴力电子游戏是攻击行为产生的前因变量, 并且提出可以用一般攻击模型(General Aggression Model, GAM)来解释这一结论。然而, Ferguson等人的研究表明, 暴力电子游戏不是攻击行为产生的前因变量, 而是攻击行为产生的催化剂, 并提出催化剂模型(Catalyst Model, CM)来解释该结论。由于社会心理研究中, 实验研究难以严格控制, 导致研究结果大径相庭, 暴力电子游戏影响攻击行为的争论还在不断扩大。未来要加强对暴力电子游戏和攻击行为的测量, 同时还需整合一般攻击模型和催化剂模型指导实证研究, 最后从认知偏差以及社会认知神经科学视角寻求暴力电子游戏对攻击行为影响的新证据。     

儿童攻击行为的短期追踪干预研究:从社会信息加工的角度

以社会信息加工模型(Social Information-Processing Model,简称SIP)为理论依据设计社会认知干预方案,将被试(包括132名攻击性儿童)分为实验组、安慰剂(阅读)组和控制组进行短期追踪干预研究,在此基础上考察该干预方案对减少儿童的攻击行为以及提高社会信息加工能力的作用。研究结果表明:(1)该干预方案对提高攻击性儿童的社会信息加工能力有明显的即时效果和持续效果,具体表现为该方案有效地减少了攻击性儿童的敌意归因偏见和攻击行为的产生,有助于攻击性儿童建立关系目标并正确认知攻击行为的后果;(2)班主任评定三组儿童的攻击行为显著减少,评定结果可能受到期望效应的影响。     

Five-Factor Model and alcohol outcomes: Mediating and moderating role of alcohol expectancies

The aim of the present study was to examine the relationship between the Five-Factor Model of personality and alcohol expectancies (AEs) with different alcohol outcomes. The sample was composed of 738 participants (63.7% females). Path and regression analyses were performed to test the mediation and moderation effects. The results indicated that Neuroticism was related to alcohol consumption through Positive Alcohol Expectancies, and that Negative Alcohol Expectancies, but also Positive Alcohol Expectancies, partially mediated the relationship of Neuroticism to alcohol-related problems. In addition, Positive Alcohol Expectancies partially mediated the associations of extraversion and low conscientiousness with weekend Standard Drink Units (SDUs), and they completely mediated the associations of these personality variables with alcohol-related problems. Additional direct paths were found from low agreeableness to weekly SDUs and alcohol-related problems; and from low openness to weekend SDUs. Moderation effects of alcohol expectancies on personality and both alcohol use and alcohol-related problems were also found. The present research contributes new evidence on the influence of the five factors of personality on alcohol outcomes, and the mediation/moderation role of alcohol expectancies. These findings can be useful to develop prevention/intervention programmes.
