情绪性工作记忆对选择性注意的影响

选取大学本科生33名,采用情绪启动范式与再认范式相结合,要求被试依次完成情绪词识记、目标面孔性别判断及情绪词再认任务,探讨保存于工作记忆中的情绪性刺激对面孔性别判断任务的影响。结果显示:(1)在中性和恐惧情绪启动刺激条件下,被试对目标面孔性别判断的反应时要显著长于悲伤条件。(2)在愉悦情绪启动词条件下,线索提示有效性差异显著;在无效线索提示条件下,启动刺激的不同情绪效价差异显著。(3)对情绪面孔性别与被试性别一致性/非一致性两种条件下反应时对比发现,男、女被试在情绪面孔性别判断任务中均表现出异性相吸效应。综上所述,保存在工作记忆中情绪刺激会对面孔性别的识别产生自上而下的影响。     

在押毒品犯人格的基本特征及其相关因素的研究

本研究以 3 78名在押毒品犯为被试 ,以CPI为测量工具 ,探讨了在押毒品犯的基本特征和类型特征 ,并采用方差分析技术研究了影响毒品犯人格的若干因素。结果发现 ,与对照组相比 ,在押毒品犯除了在“自我控制”分量表上未发现显著差异外 ,其余的 1 9个分量表上均有显著差异 ;在押毒品犯在四种人格类型上的分布不平衡 ,主要集中在Delta类型 ;年龄、关押时间对毒品犯的人格特征的变异有一定影响 ,而减刑次数的影响不显著     

中小学生阅读图文课文的眼动实验研究

本研究采用眼动方法,对85名小五、实二和高二年级学生阅读图文课文的阅读理解指标和眼动指标进行考察。结果表明：（1）学生阅读不同呈现方式和难度课文的阅读理解指标和眼动指标,一般都具有明显的年龄发展特征;（2）学生阅读不同呈现方式课文的阅读理解指标和眼动指标,有图课文大多显著优于无图课文;（3）学生阅读不同难度课文的阅读理解指标和眼动指标,易课文显著优于难课文。     

汉语语句重音的分类和分布

通过两个独立进行的重音标注实验对汉语语句重音的分类和分布进行了初步探讨。实验l是由60位普通被试参加的音节重音突显度的知觉实验。实验2是由本文三位作者参加的重音类别标注实验,在此实验中语句重音被划分为节奏重音和语义重音。实验2中对于语句重音的分类性标注结果得到了实验l中普通被试对音节重音突显度知觉结果的支持,这说明人们确实能够感知到两种不同类型的重音。实验结果还表明,节奏重音倾向于出现在较大韵律单元内的最末韵律词的末音节上,并且与适当的停延相伴生,语义重音的分布则与语句的韵律结构的关系不大。     

移植免疫中微嵌合现象给我们的思考

随着移植免疫学研究的不断深入发展,诱导免疫耐受克服移植排斥反应已成为器官移植的主要研究目标。Starzl提出“双向移植排斥理论”并阐述临床使用免疫抑制药物下移植排斥反应的特点,突破了原有单向移植排斥理论的框架。“双向移植排斥理论”及理论内存在的问题给予我们众多有益的思考,在移植免疫学研究中,只有坚持用系统原则动态的看待事物间的联系与矛盾,进行科学实践,才能获得正确的理论,从而进一步推动移植免疫学的发展。     

Factors Influencing Household Waste Recycling Behavior: Test of an integrated Model1

Although there has been an official household waste recycling system in Taiwan, the system still works rather inefficiently because of problems such as resistance from citizens, political complexity, and those arising from culture. This study examines the antecedents of the behavior of household waste recycling in the context of an integrated model. This model incorporates a wide variety of important factors from previous research on environmental behavior into a single theoretical framework provided by the theory of planned behavior (TPB). This model was tested using data from a sample of 386 community residents in Kaohsiung, each of whom completed a survey. The results suggest that in addition to the TPB variables, perceived moral obligation further improved the prediction of intention to recycle household waste. Implications for operating household waste recycling systems are discussed.

A two‐part mixed effects model for cigarette purchase task data

The Cigarette Purchase Task is a behavioral economic assessment tool designed to measure the relative reinforcing efficacy of cigarette smoking across different prices. An exponential demand equation has become a standard model for analyzing purchase task data, but its utility is compromised by its inability to accommodate values of zero consumption. We propose a two‐part mixed effects model that keeps the same exponential demand equation for modeling nonzero consumption values, while providing a logistic regression for the binary outcome of zero versus nonzero consumption. Therefore, the proposed model can accommodate zero consumption values and retain the features of the exponential demand equation at the same time. As a byproduct, the logistic regression component of the proposed model provides a new demand index, the “derived breakpoint”, for the price above which a subject is more likely to be abstinent than to be smoking. We apply the proposed model to data collected at baseline from college students (N = 1,217) enrolled in a randomized clinical trial utilizing financial incentives to motivate tobacco cessation. Monte Carlo simulations showed that the proposed model provides better fits than an existing model. We note that the proposed methodology is applicable to other purchase task data, for example, drugs of abuse.     

Analgesic effect of Facebook: Priming with online social networking may boost felt relatedness that buffers against physical pain

Social networking sites (SNSs) are extremely popular for providing users with a convenient platform for acquiring social connections and thereby feeling relatedness. Plenty of literature has shown that mental representations of social support can reduce the perception of physical pain. The current study tested whether thinking about SNS would interfere with users’ perceptions of experimentally induced pain. Ninety‐six undergraduate Facebook users were recruited to participate in a priming‐based experiment. They were randomly assigned to one of the three study conditions (SNS prime, neutral prime, or no prime) via rating the aesthetics of logos. The results showed that participants exposed to SNS primes reported less pain of immersion in hot water than did both control groups (neutral‐ and no‐prime). Felt relatedness mediated the link between SNS primes and diminished pain perceptions. This research provides the first demonstration that thinking about SNS can lower experienced physical pain among Facebook users. Online social networking may serve as an analgesic buffer against pain experience than previously thought. The SNS‐enabled analgesia has far reaching implications for pain relief applications and the enhancement of well‐being in human‐interaction techniques.
