Contextual effects on prejudiced attitudes: When the presence of others leads to more egalitarian responses

In the present paper, we tested the hypothesis that the physical presence of other ingroup members may ameliorate Whites’ spontaneous affective responses toward Blacks. Results of Study 1 demonstrated that IAT-assessed attitudes toward Blacks were indeed less negative when participants were tested in small groups rather than individually. Study 2 shed light on the underlying processes by demonstrating that respondents at the presence of others displayed increased accessibility to egalitarian-related concepts after Black primes, as compared to respondents tested individually. Overall, results point to the wide malleability of spontaneous affective responses and to the possibility that contextual factors, like the presence of other individuals, might automatically activate egalitarians goals. Results are discussed in relation to current models of automatic intergroup bias and preconscious control over it.     

Psychometric evaluation and further validation of the Hagedoorn et al. modified EVLN measure

The aim of the present study was to evaluate and further validate a modified Exit, Voice, Loyalty and Neglect (EVLN) instrument (Hagedoorn, Van Yperen, Van de Vliert & Buunk, 1999), in a Swedish sample (n= 792). To test the underlying scaling assumptions, the convergent and divergent validity, a multitrait/multi-item analysis was conducted and factor analyses were used to evaluate the factor structure. The concurrent validity was tested by using the modified EVLN instrument as predictor and three different forms of justice as criteria in the analysis. The criterion-related validity was tested and an association between exit behavioral response and actual exit behavior was found (predictive validity). The results showed that the instrument may be considered to be a valid measure with the exception of the aggressive voice scale.     

幼儿自我调控的中日比较

实验以中日77名大班幼儿为被试(其中中国幼儿40名,日本幼儿37名).在实验中,根据幼儿园的日常生活,设置幼儿与同伴间矛盾场面(抑制场面和主张场面)的测试问题,采用逐张呈现图片并一对一询问的方式进行实验.根据幼儿在测试问题上的情绪反应与行为反应数据,比较中日幼儿自我调控的特征,结果表明:(1)在与同伴间的矛盾场面中,中国幼儿发生情绪反应的人数比率显著小于日本幼儿;(2)在表现出情绪反应的幼儿中,不论在抑制场面还是在主张场面,日本幼儿都比中国幼儿有更多的"自我抑制"或"自我抑制"倾向,而中国幼儿比日本幼儿出现了更多的"依赖教师"和"冲动行为"倾向;(3)中国幼儿的行为反应因情绪反应强度的变化表现出了差异,而日本幼儿的行为反应没有随着情绪反应强度的不同表现出差异.     

The Passion to Heal: A Theological Pastoral Approach to HIV/AIDS

Abstract. The global pandemic of HIV/AIDS is the most significant challenge of our time. The ongoing conversation between religion and science comes to a critical juncture in this pandemic. The global community has not yet found a vaccine or cure for this virulent virus, which will likely claim five million more lives in the coming year. The global statistics challenge even the most sophisticated imagination, with projections in the tens of millions of people dead, orphaned children, and many more living in various stages of incapacitation or diminished lives. There is a common prophetic religious imperative among Western faith communities that urgently requires both science and religion to respond. Both disciplines define their scope and purpose as universal, and the global pandemic provides a significant challenge to that universal claim. Regardless of the many differences among the nations and peoples challenged by this pandemic, there is a common moral foundation to which the Western religious and scientific traditions must respond. Religion and science cannot deny their respective social responsibilities by claiming the role of neutral bystander. There are several critical ethical choices to be made in response to the pandemic, and the disciplines of religion and science are critical in formulating those choices.     

短声强度为95dB时猫的两耳听现象

研究短声强度为95dB时猫的两耳听现象,探讨两耳干涉作用和交叉听力在听觉脑干电反应(ABR)上的表达。以ABR为检测指标,观察和比较耳蜗破坏前后对侧耳负荷75dB SWN时95dB短声诱发的ABR各波振幅的变化。结果：(1)耳蜗破坏前对侧耳负荷的75dB SWN可使95dB短声诱发的ABR之PⅢ、PⅣ波振幅增大(P＜0．01)。(2)耳蜗破坏后对侧耳负荷的75dB SWN对95dB短声诱发的ABR各波振幅无影响(P＞0．05)。(3)耳蜗破坏前对侧耳负荷75dB SWN时95dB短声诱发的ABR之PⅣ波振幅比耳蜗破坏后95dB短声诱发的ABR之PⅣ减小(P＜0．05)。结论：短声强度为95dB时,交叉听力现象在ABR之PⅢ、PⅣ波上均有表达,与75dB5WN产生的两耳干涉作用仅在ABR之PⅣ波有表达。     

Stepping Responses in Young and Older Adults Following a Perturbation to the Support Surface During Gait

The objective of this work was to investigate the influence perturbation direction has on postural responses during overground gait, and whether these responses are age related. Differences in stepping patterns following perturbations of the support surface were examined in the frontal and sagittal planes during forward walking. Eleven young and 10 older adults completed Mini BESTest, hip strength tests, and 45 perturbed walking trials, triggered on heel contact. Lateral perturbations were more challenging to postural stability for both groups. Step length measures showed young adults recovered in the step proceeding the perturbation, while older adults needed additional steps to regain balance. Young adults arrested center of mass movement by producing larger step widths than older adults following the support surface perturbation.     

不同情绪诱发方法有效性的比较研究

采用自我报告和生理反馈法,从强度、纯度、时间进程三方面考察图片、音乐、电影和回忆四种常用情绪诱发方法诱发出的高兴、激动、悲伤和恐惧四种不同维度的情绪的有效性。得出结论：（1）总体上,音乐诱发情绪的强度最高,图片最低;在积极情绪中,音乐诱发的强度普遍较高,图片较低;消极情绪中,回忆诱发的强度普遍较高,音乐较低。（2）音乐诱发情绪的纯度较高,图片较低。（3）效价和激活度不同,情绪的时间进程不同,高兴能持续将近1分钟,激动能持续2分30秒,悲伤能持续1分30秒,而恐惧能持续2分钟。     

动物信号追踪和目标追踪行为及其神经机制

信号追踪和目标追踪的实质是条件刺激和非条件刺激结合诱导的条件性接近反应.条件刺激的预测作用和诱因作用是信号追踪和目标追踪的重要机制;伏隔核、中央杏仁核和前扣带回在信号追踪和目标追踪过程中具有重要作用;然而,大脑皮层和海马损伤对两者影响较小.DA功能降低可损害信号追踪获得和表达;而脑内DA含量增加可提高目标追踪.未来的研究中,应该规范条件刺激和非条件刺激的类型和设置方法,针对不同的研究目的个别地或同时地测量信号追踪和目标追踪.     

Establishing books as conditioned reinforcers for preschool children as a function of an observational intervention

We tested the effects of an observational intervention (Greer & Singer-Dudek, 2008) on establishing children's books as conditioned reinforcers using a delayed multiple baseline design. Three preschool students with mild language and developmental delays served as the participants. Prior to the intervention, books did not function as reinforcers for any of the participants. The observational intervention consisted of a situation in which the participant observed a confederate being presented with access to books contingent on correct responses and the participant received nothing for correct responses. After several sessions of this treatment, the previously neutral books acquired reinforcing properties for maintenance and acquisition responses for all three participants.     

Punitive versus compensatory reactions to injustice: Emotional antecedents to third-party interventions

The almost exclusive focus on punishment and inattention to compensatory alternatives in studies involving experimental games may yield patterns that do not accurately reflect how and when people respond to injustice, particularly if punishment and compensation are not psychologically equivalent approaches to justice restoration. In the current study, we examined participants' preference for punitive and compensatory actions, while also exploring emotional determinants and boundary conditions. Our results indicated that participants actually compensated victims more than they punished offenders and that the majority of participants assigned both. Furthermore, although both interventions were associated with emotional experiences of moral outrage toward the offender, self-focused emotions reflecting feelings of threat only predicted compensation and only when victims were aware that they had been victimized. These findings augment our understanding of third-party interventions, emphasizing the importance of considering response alternatives when studying the psychology of justice.
