媒体多任务的效用：听觉信息干扰和视听信息整合的实验证据

采用心理旋转范式和词汇判断范式,探讨媒体多任务经验不同者在听觉信息干扰和视听信息整合情境下对图形一致性和真假词的判断表现。结果发现：（1）以判断图形一致性为实验任务,在无声和低音干扰条件下,低经验组的正确率均显著高于高经验组,两组的反应时差异均不显著;在高音干扰条件下,高经验组的反应时显著短于低经验组,正确率则没有显著差异。（2）以真假词判断为实验任务,对真词进行判断,在三种听觉条件下,高经验组在语音匹配条件下的反应时最短,与低经验组无显著差异,但正确率显著高于低经验组,与另两种听觉条件没有显著差异;低经验组在语音匹配条件下的反应时显著长于另两种听觉条件,正确率则显著高于无声条件,与不匹配条件差异不显著。对假词的判断,低经验组在三种听觉条件下的反应时均显著短于高经验组,正确率与高经验组均无显著差异。研究表明,媒体多任务经验丰富者相比经验缺乏者受到任务无关的纯短高音干扰的影响要小,在需要视听通道语义整合的加工中具有一定的优势。     

社会性线索对内隐和外显元认知监控的影响

本研究以词图匹配材料为学习材料,以“大多数人选择的情况”为社会性线索,通过分析行为表现和眼动指标,探讨了社会性线索对内隐和外显元认知监控的影响。结果显示：（1）第一次信心判断时,外显信心判断显著高估,内隐信心判断较为准确。第二次信心判断时,在线索一致条件下,外显信心判断等级显著高于内隐信心判断。（2）在提供社会性线索阶段和第二次再认阶段,与线索一致条件相比,线索不一致条件下被提示项的注视时间更短,而未提示项的注视时间更长,且个体改变选择的次数显著增多。结果表明：内隐和外显元认知监测存在分离,内隐监测的准确性更高,外显监测受社会性线索的影响更大;而内隐和外显的元认知控制受社会性线索的影响趋同。     

数字媒体使用与心理健康的理论争议和研究证据

采用系统综述的方法对数字媒体使用与心理健康的不同关系类型做了详细梳理并总结了争议的原因。结果发现,目前理论上的争议可归纳为四大类：负相关、正相关、不相关以及U形关系。研究结果不一致的原因可能与数字媒体的使用性质、心理健康的内涵、研究的取向和设计形式以及被试群体有关。该结果有助于从宏观上把握数字媒体使用与心理健康的研究动态并批判性地看待既有研究结果。未来应将数字媒体使用做精细化区分并加强实验研究准确揭示因果关系,以便厘清该领域的争论。

     

HPV疫苗如何走入大众视野？——基于微博相关视频的内容分析

以微博相关视频为研究对象,对选取样本进行内容分析,探究有可能影响公众健康态度和疫苗健康决策的社交媒体内容如何呈现人乳头瘤病毒(human papillomavirus, HPV)疫苗相关议题,并利用扩展的平行过程模式(expended parallel process model,EPPM)对其内容中的“威胁”和“效能”信息分析得出,兼具大众传播功能和人际传播影响力的微博中,不同来源的HPV疫苗视频对HPV健康风险及疫苗改善措施的信息呈现上存在差异,对于HPV疫苗的接种信息呈现不足,有可能影响用户的健康效能,对公众的健康促进需要更加全面、准确、平衡的HPV疫苗信息呈现。

     

The Pedophile and the Pious

Abstract

This chapter is an attempt at providing heretofore unpublished and essential background information and historical understanding about clerical sexual abuse, which might allow some to contextualize differently the serious problem in the Roman Catholic and other faith based communities in the United States. Discussion indicates some variables that might provide researchers with clear markers for differentiation. Directions for future research are discussed.     

Make the manikin move: Symbolic approach–avoidance responses affect implicit and explicit face evaluations

The present research aimed to replicate and extend findings of Huijding, Muris, Lester, Field, and Joosse (2011), investigating whether symbolic approach–avoidance responses can induce implicit and explicit evaluation biases. Faces with a neutral expression were shown on a computer screen, and participants were instructed to repeatedly move a manikin towards some faces (approach) and away from other faces (avoidance). An affective priming task and a face rating task were used to assess training-compatible differences in implicit and explicit face evaluations, respectively. Results showed that the manikin training was successful: The priming task revealed more positive implicit evaluations of approached than avoided faces, and approached faces were rated more positively than avoided ones in the face rating task. These findings replicate those of Huijding and colleagues by demonstrating training effects on explicit evaluations, and they extend them by demonstrating effects on implicit evaluations.     

Crones, Dirty Old Men, Sexy Seniors: Representations of the Sexuality of Older Persons

The representations of the sexuality of older persons in American society are neither flattering nor accurate. Often what is presented is filled with confusion, uncertainty, and contradictions. Sexuality of old people, like sexuality of adolescents, frightens most adults in between. Evidence suggests hope that in popular culture, conventional representations of sexless older people are finally undergoing a change. The popular literature aimed at elderly or midlife audiences increasingly portrays older persons as healthy, vigorous, and not unattractive. Since in the popular mind attractiveness and sexuality are believed to be closely linked, this change signals an increased willingness to credit old people who are aging well (i.e., who look and act young) with being sexually interested and probably active.
