Changing Gender Roles in Prime-Time Commercials in Malaysia,Japan, Taiwan,and the United States

This study showed that during prime time, a new paradigm of gender role depiction has emerged in prime-time commercials in Japan, Taiwan, and Malaysia. Even though some stereotypes about the presentation of gender in commercials persist (for setting, product type, voice-over), the study found an equal number of males and females appearing as primary characters in commercials during prime time. In Japan, Malaysia, and Taiwan, the majority of commercials depicted males and females in nonstereotypical gender roles. Some shifts were also observed for role depiction in prime-time commercials in the United States. Reasons for these changes are discussed.     

正性情绪诱导下的自我参照加工：来自ERPs的证据

采用事件相关电位考察正性情绪对自我参照加工程度效应的影响。实验采用图片启动范式, 先呈现情绪图片, 然后再呈现自我参照刺激。实验发现, 在P2上, 中性情绪条件比正性情绪条件激发了更大的波幅, 高自我相关的刺激比其它刺激诱发了更短的P2潜伏期; 在N2上, 高自我相关名字比中等自我相关名字和非自我相关名字诱发了更小的N2的波幅和更长潜伏期; 在P3上, 高自我相关名字比中等自我相关名字和非自我相关名字诱发了更大的P3波幅, 中等自我相关名字比非自我相关名字诱发了更大的P3波幅。实验结果表明, 人类大脑对正性情绪刺激的加工可能是不敏感的。无论在正性情绪启动还是中性启动的影响下, 自我参照加工都能展现出稳定的特征, 而且高自我相关的刺激会得到更为深入和精细的加工, 表现出自我参照加工的程度效应。     

面孔审美加工的神经机制及个体差异

外显和内隐的面孔审美加工的脑成像研究表明,美的面孔比不美的面孔导致眶额皮层、伏隔核、杏仁核等奖赏脑区更大的激活。脑电研究则发现了与面孔审美加工有关的早期负波和晚期正成分。面孔审美加工有关的脑区活动也受到性别、生理周期等个体因素的调节。未来的研究需要比较美的面孔与其它奖赏刺激加工的神经机制,探讨面孔审美加工的不同阶段及时间进程,在面孔知觉的框架下形成合理的面孔审美加工的神经模型。     

心理韧性、孤独感、自我效能感预测老年人主观幸福感的优势分析

心理韧性、孤独感、自我效能感都会影响老年人的主观幸福感,但三者影响程度的相对大小尚不清楚。为考察其影响力的大小,本研究采用了优势分析的方法。选取心理韧性量表、UCLA孤独量表、一般自我效能感量表分别测量老年人的心理韧性、孤独感、自我效能感,主观幸福感量表、费城老年中心信心量表测量老年人主观幸福感。优势分析结果表明,孤独感对老年人主观幸福感的预测力大于心理韧性与自我效能感;心理韧性的预测力大于自我效能感。本研究提示减少孤独感是提升老年人主观幸福感的重要途径,而老年人的心理韧性和自我效能感对提升老年人主观幸福感有一定的作用。     

先前知识、超文本层次深度和类型对低结构化信息搜索的影响

探讨先前知识、超文本层次深度和类型对低结构化中文信息搜索的影响。采用2(先前知识)×8(文本组织形式)的被试间设计,以平均搜索时间和迷路指数为因变量。结果发现:(1)先前知识对线性文本和超文本(尤其是层次型超文本)的搜索均有利;(2)随着层次深度的增加,对超文本的搜索时间显著增加,迷路指数也呈增加的趋势;(3)搜索线性文本的迷路指数显著低于超文本;(4)不同类型超文本的搜索绩效基本无显著差异。因此,先前知识、层次深度对超文本信息搜索的影响比超文本类型和信息的结构化水平更重要。     

面孔—人格知觉的影响因素

人们会迅速地对目标人物的面孔线索进行人格特质分析,进而形成对目标的人格第一印象。在这个面孔—人格知觉的过程中,知觉结果会受到知觉对象、知觉者以及两者交互作用的影响。本文基于这三个方面对影响面孔—人格知觉的因素进行了综述和展望,以期更系统、科学地研究与看待面孔—人格知觉,并为人际印象设计与管理等提供理论参考。     

失眠患者静息态脑网络的改变：网络内与网络间的功能连接异常

失眠已成为现代人群中的一种高发健康问题。静息态功能磁共振以其数据采集便利性和无创性, 成为失眠研究的主要成像手段之一。基于近年来静息态功能磁共振的发现, 失眠患者存在前额叶、颞叶、前扣带回、脑岛等认知-情绪神经环路的异常。大尺度脑网络是涵盖多个脑区、功能相对单一的大脑结构。失眠患者存在默认网络、突显网络、认知控制网络和负性情绪网络内部活动与连接异常, 而且呈现出以默认网络为核心, 包含认知控制网络、突显网络、负性情绪网络的网络间连接异常模式。此外, 结合症状、治疗和大尺度脑网络的视角, 可为失眠的“精准治疗”提供神经理论依据。未来研究可结合大数据和多模态分析技术, 验证静息态功能磁共振已有发现。而失眠的纵向追踪和队列研究会有利于进一步阐释失眠的神经机制。     

Suicidal Ideation of Psychiatrically Hospitalized Adolescents has One-Year Predictive Validity for Suicide Attempts in Girls Only

Clinicians commonly incorporate adolescents’ self-reported suicidal ideation into formulations regarding adolescents’ risk for suicide. Data are limited, however, regarding the extent to which adolescent boys’ and girls’ reports of suicidal ideation have clinically significant predictive validity in terms of subsequent suicidal behavior. This study examined psychiatrically hospitalized adolescent boys’ and girls’ self-reported suicidal ideation as a predictor of suicide attempts during the first year following hospitalization. A total of 354 adolescents (97 boys; 257 girls; ages 13–17 years) hospitalized for acute suicide risk were evaluated at the time of hospitalization as well as 3, 6, and 12 months later. Study measures included the Suicidal Ideation Questionnaire-Junior, Multidimensional Anxiety Scale for Children, Children’s Depression Rating Scale-Revised, Beck Hopelessness Scale, Youth Self-Report, and Personal Experiences Screen Questionnaire. The main study outcome was presence and number of suicide attempt(s) in the year after hospitalization, measured by the Diagnostic Interview Schedule for Children. Results indicated a significant interaction between suicidal ideation, assessed during first week of hospitalization, and gender for the prediction of subsequent suicide attempts. Suicidal ideation was a significant predictor of subsequent suicide attempts for girls, but not boys. Baseline history of multiple suicide attempts was a significant predictor of subsequent suicide attempts across genders. Results support the importance of empirically validating suicide risk assessment strategies separately for adolescent boys and girls. Among adolescent boys who have been hospitalized due to acute suicide risk, low levels of self-reported suicidal ideation may not be indicative of low risk for suicidal behavior following hospitalization.     

“蚁族”群体的公正世界信念与幸福感研究

以居住在北京小月河地区的304名“蚁族”为被试,采用公正世界信念问卷、积极消极情感问卷和生活满意度问卷,考察了一般公正世界信念、个人公正世界信念以及幸福感之间的关系,结果表明:(1)“蚁族”的生活满意度偏低,但其情绪状态仍然乐观,积极情感体验较高,且具有较高水平的公正世界信念;(2)公正世界信念对幸福感有显著的正向预测作用,公正世界信念水平越高的“蚁族”越幸福;(3)个人公正世界信念在一般公正世界信念和幸福感间起中介作用,即越相信世界是公正的“蚁族”更倾向于相信自己已经或即将受到的对待是公正的,最终提升幸福感。
