风险偏好预测中的性别差异和框架效应

11 8名大学生被试在得益和损失两种任务框架下对自己、其他男性和女性的风险偏好进行了预测。结果发现 ,被试在损失框架下对各类对象风险偏好的预测均高于得益框架 ,且都高估了男性的风险偏好 ,低估了女性的风险偏好。在损失框架下 ,女性被试对各类对象的风险偏好预测高于男性的预测。研究认为 ,性别原型知识、任务框架和即时情绪共同影响被试的风险偏好预测。     

多动症儿童与认知事件相关电位的实验研究

本研究通过对29名多动症(MBD)儿童与正常儿童认知事件相关电位各成份的比较,结果发现多动症组与正常儿童组在反映大脑认知功能P300潜伏期有明显的差异,从而说明P300可以作为检测多动症儿童的参考性的客观指标。     

IAT效应在不同目标概念水平上的差异研究

采用IAT实验设计,考察大学生对不同概念词的内隐态度之间的差别。结果发现,八组实验材料都产生了显著的IAT效应;不同性别的测验材料的IAT效应间不存在显著差异,不同喜好程度的测验材料的IAT效应间存在显著差异,且两个因素存在显著的交互作用。研究表明,IAT效应既可在上位概念水平上产生,亦可在下位概念水平上产生。     

The Organizational Principles of Online Political Discussion: A Relational Event Stream Model for Analysis of Web Forum Deliberation

The structure of online political discussion has proven important to deliberative democracy. However, the organizational mechanisms of the structure receive little attention in scholarship. This study employed a random‐effects relational event model to differentiate and examine the effects of a set of organizational principles in web forum discussions. By analyzing more than 175,000 forum replies, the study found that cross‐ideological debate is an independent organizational mechanism even when accounting for the effects from common interests, opinion congruity, purely structural effects, and conversational norms. These findings differ from the selective exposure thesis and previous incidental claims of political disagreement. In addition, the findings indicate that endogenous mechanisms and opinion congruity could influence the tendency of cross‐ideological debate to varying degrees.

成就目标对青少年成就动机和学业成就影响的研究

本研究在迈尔（Maehr）等人研究的基础上,考察了成就目标（任务目标和能力目标）与动机和学业成就之间的关系。结果表明,任务目标通过内部动机对学业成就产生积极的影响,能力目标通过外部动机对学业成就产生消极的影响。     

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.

两岁儿童对母亲的依恋类型

本研究采用实验室观察法,考察122名21-27个月龄的儿童对母亲的依恋类型,实验室程序包括儿童的自由活动、与陌生人的交往、在多种压力情境下的行为表现,与母亲的分离-重聚等.结果发现(1)本研究中使用的实验室观察程序能够有效地测查两岁儿童对母亲的依恋行为.(2)中国两岁儿童对母亲的依恋有四种类型淡漠型依恋、安全型依恋、缠人型依恋、混乱型依恋,分布比例分别为11%,73%,7%,9%.其中安全型和混乱型依恋的表现与国外研究者描述的美国、日本等国家儿童的行为大体相同,但淡漠型和缠人型依恋为我国儿童所特有,其表现特点与国外研究者描述的焦虑-回避型不安全依恋及焦虑-矛盾型不安全依恋有明显区别.     

厌恶情绪与自杀行为的关系

自杀导致人类死亡的人数与日俱增,然而自杀的心理机制却并不清楚。最近研究发现,厌恶情绪是导致自杀的主要情绪因素,个体因为自身厌恶而走向自杀。厌恶情绪是一种对自己和他人排泄物等反感的基本情绪,促进个体远离毒性和疾病,从而产生“免疫行为”。许多心理问题来自于对周围人或事物的厌恶,有自杀行为的个体对自身极其厌恶,说明他们的厌恶情绪出现了问题。如同躯体免疫攻击自身一样,自身厌恶是自杀意念的关键因素,早年创伤是其根源,生活压力和精神疾病也参与厌恶诱发自杀意念。厌恶诱发自杀意念的神经基础与HPA轴和五羟色胺系统有关。未来研究可利用神经影像和电生理等神经科学技术,检验自杀行为的神经机制,探讨厌恶情绪影响自杀行为的心理和神经机制。
