An isolation effect in serial memory for spatial information

This paper reports the first demonstration of an isolation effect or von Restorff effect (von Restorff, 1933) in the context of a spatial-memory task: Short-term serial recall was enhanced for both the location and the serial position of one red dot presented amongst a sequence of otherwise black dots. When the serial position of the isolate was fixed, the spatial isolation effect only emerged when participants received a control block of trials before the block of isolation trials (Experiment 1). However, when the serial position of the isolate was varied across isolation trials, an isolation effect was still produced regardless of condition order (Experiment 2). It is suggested that both temporal grouping strategies and greater item-specific processing may have contributed to the enhanced retention of the isolate.     

Median decision techniques as an alternative to the classical statistical inference test

In the research area, the criterion to test a hypothesis is frequently the distance of each subject from the mean of the distribution. This concept of distance is constantly used and re-used as a source of evidence in the search for significant contrasts with respect to models of theoretical probability. This paper proposes a number of ideas regarding the use of new distance indicators related to statistics that rely less heavily on parametric assumptions, in particular, the use of median confidence intervals. We have simulated via EXCEL different data samples for a design of two independent groups under 15 different conditions in two different situations: mean equality and mean differences. The results showed the high sensitivity of the comparison of the confidence intervals, especially if a strict decision criterion is used. However, we did not obtain good results for sensitivity. In fact, in some cases, the comparison of the confidence intervals of the mean worked better than those of median.     

词切分对印-英双语者阅读影响的眼动研究

以25名印-英双语者为被试,采用EyeLink2000眼动仪,探讨词切分对印-英双语者阅读的影响。实验一要求被试阅读印地语句子,实验二要求被试阅读英语句子,词切分方式有三种：正常条件、无空格隔词加灰条件和无空格条件。结果发现：（1）对印-英双语者阅读自己的两种官方语言来说,空格因素在其阅读中发挥着积极作用,删除空格会明显影响他们的阅读;（2）在无空格隔词加灰条件和无空格条件下,印-英双语者阅读英语时下降的速度显著低于阅读印地语的,这表明空格因素的作用会受语言特点的制约。

Open or close the door to the outgroup? Diversity beliefs moderate the impact of group boundary permeability on attitudes toward the outgroup

The present research investigated the moderating role of diversity beliefs with the aim of reconciling inconsistent findings regarding the impact of group boundary permeability on attitudes toward outgroup. In Study 1, all variables were measured with self‐report scales completed by Chinese participants. In Study 2, diversity beliefs were manipulated by randomly assigning Chinese participants to a high or low diversity belief condition. In Study 3, we replicated the moderating model with American participants. Results of all three studies indicated that diversity beliefs moderated the relationship between group boundary permeability and attitudes toward outgroup. Individuals with high diversity beliefs held more positive attitudes toward the outgroup when the group boundary was permeable (vs. impermeable). Conversely, individuals with low diversity beliefs held more negative attitudes toward the outgroup when the group boundary was permeable (vs. impermeable). These findings suggest that when the inflow of the outgroup members is inevitable, attitudes toward the outgroup may be effectively improved by increasing diversity beliefs.     

具身模拟在汉语肢体动作动词理解中的作用

通过3个实验, 考察具身模拟在汉语肢体动作动词理解中的作用。实验1考察在整字启动下具身模拟对运动通道中箭头方向判断的影响, 发现理解肢体动作动词在运动通道中存在着动作-汉字相容效应, 汉字的具身方向与箭头方向一致促进被试对箭头方向的判断。实验2考察在整字启动下具身经验对视觉通道中字母位置判断的影响, 发现理解肢体动作动词在视觉通道中存在着动作-汉字相容效应, 汉字的具身方位与字母方位一致促进对字母方位的识别。实验3采用义符启动范式考察义符与整字的具身模拟, 发现理解汉语肢体动作动词不仅在整字层次上存在着具身模拟, 在部件层次上也存在着具身模拟。义符在汉字加工中期被激活了, 并且持续到加工晚期。整个研究表明, 汉语肢体动作动词理解是一个跨通道的具身模拟过程, 具身模拟在汉语肢体动作动词的理解中起着非常重要的作用。     

颜色词的语用关系影响颜色认知

在汉语中, 红、紫、蓝、绿都有各自的语言标签。但在日常语用中, “红”与“紫”比“蓝”与“绿”的语用关系更加密切。“红”与“紫”具有更多的联合表达, 具有更为类似的颜色感应。采用颜色相似性判断、颜色分类和颜色再认任务, 考察汉语母语者对“红–紫”色块和“蓝–绿”色块的认知, 探讨语用关系对颜色认知的影响。结果表明, 语用关系不影响汉语母语者的颜色相似性判断, 却影响颜色分类和颜色再认。与“蓝–绿”色块比, 汉语母语者在包含记忆成分任务中对“红–紫”色块具有认知劣势。整个研究表明, 由语用关系引起的颜色感应在颜色认知中起着重要调节作用, 记忆编码在此过程中起着直接作用。     

基于IAT和SEB的内隐性别刻板印象研究

采用内隐联想测验(IAT)和刻板解释偏差(SEB)两种测量内隐社会认知的方法考察了120名大学生被试的内隐性别刻板印象。结果表明,大学生中普遍存在着较强的内隐性别刻板印象,人们对于男性以及男性本身持有的刻板印象符合传统的认知习惯,而对于女性及女性持有的刻板印象则与传统的认知习惯有所不同。用IAT和SEB这两种方法测量大学生的内隐性别刻板印象,在被试的性别变量上得到的结果不一致。     

性别刻板印象维护的心理机制

性别刻板印象对人们有着重要影响。反性别刻板的行为违背了人们对性别角色的期望和要求,人们为了维护自己的性别刻板印象会采用不同的策略来对反性别刻板的行为作出反应。文章介绍了认知过程中对反性别刻板信息的抗拒和行为反应中对反性别刻板行为的抵制功能模型,分析了人们维护性别刻板印象的心理机制,并对有关性别刻板印象维护的研究进行了评价和展望
