自尊的认知神经机制

自尊是个体对自己总体的情感性评价。自尊有助于促进个体的心理健康,帮助个体应对威胁,具有重要的适应价值。近年来随着社会认知神经科学的兴起,关于自尊的认知神经机制的研究日益增多,主要涉及三个方面:1)自尊与大脑的结构(如海马体积、前扣带回等区域的灰质体积)和功能(静息态下的默认网络活动以及脑区之间的功能联结性)存在一定的关联;2)自尊调节大脑对威胁的反应,与高自尊个体相比,低自尊个体面对威胁时产生更强的防御性反应,自尊通过影响个体面对威胁时的大脑活动帮助个体更好地应对威胁;3)自我评价过程涉及大脑前额叶、眶额叶、扣带回等多个脑区,自尊调节个体在自我评价过程中的大脑活动。总之,自尊作为个体重要的人格特质,与大脑的结构、功能以及活动状态等都具有一定的关系;这些发现在一定程度上揭示了自尊的神经机制,加深了对自尊及其功能的理解。     

Attention‐shift vs. response‐priming explanations for the spatial cueing effect in cross‐modal tasks

The task‐irrelevant spatial location of a cue stimulus affects the processing of a subsequent target. This “Posner effect” has been explained by an exogenous attention shift to the spatial location of the cue, improving perceptual processing of the target. We studied whether the left/right location of task‐irrelevant and uninformative tones produces cueing effects on the processing of visual targets. Tones were presented randomly from left or right. In the first condition, the subsequent visual target, requiring response either with the left or right hand, was presented peripherally to left or right. In the second condition, the target was a centrally presented left/right‐pointing arrow, indicating the response hand. In the third condition, the tone and the central arrow were presented simultaneously. Data were recorded on compatible (the tone location and the response hand were the same) and incompatible trials. Reaction times were longer on incompatible than on compatible trials. The results of the second and third conditions are difficult to explain with the attention‐shift model emphasizing improved perceptual processing in the cued location, as the central target did not require any location‐based processing. Consequently, as an alternative explanation they suggest response priming in the hand corresponding to the spatial location of the tone. Simultaneous lateralized readiness potential (LRP) recordings were consistent with the behavioral data, the tone cues eliciting on incompatible trials a fast preparation for the incorrect response and on compatible trials preparation for the correct response.     

固守与突破——从日常生活的变迁看国人工作中的人际关系

按照一般思维,日常生活与工作是两个相对对立的概念（无论是时间上还是空间上）,但通过日常生活中人与人的交往所形成的观念和衍生的人际关系,使得两者看似对立,实则紧密相联。本文以日常生活和非日常生活的理论范式为着眼点,通过历史维度的考证,来探讨日常生活诸多现象对工作中人际关系的影响及其对构建和谐社会的作用。研究表明：人的种种行为及观念的确立经历了传统日常生活的深厚积淀,而在社会发展和转型过程中又受到现代日常生活的猛烈冲击。在两者的“夹击”中,突破与固守共存,形成了中国人微妙的人际关系和复杂的人际关系网。     

Personal attitudes toward time: The relationship between temporal focus,space‐time mappings and real life experiences

What influences how people implicitly associate “past” and “future” with “front” and “back?” Whereas previous research has shown that cultural attitudes toward time play a role in modulating space‐time mappings in people's mental models (de la Fuente, Santiago, Román, Dumitrache & Casasanto, 2014), we investigated real life experiences as potential additional influences on these implicit associations. Participants within the same single culture, who are engaged in different intermediate‐term educational experiences (Study 1), long‐term living experiences (Study 2), and short‐term visiting experiences (Study 3), showed their distinct differences in temporal focus, thereby influencing their implicit spatializations of time. Results across samples suggest that personal attitudes toward time related to real life experiences may influence people's space‐time mappings. The findings we report on shed further light on the high flexibility of human conceptualization system. While culture may exert an important influence on temporal focus, a person's conceptualization of time may be attributed to a culmination of factors.     

The associations between space and order in numerical and non-numerical sequences

Spatial-numerical associations have been found across different studies, yet the basis for these associations remains debated. The current study employed an order judgment task to adjudicate between two competing accounts of such associations, namely the Mental Number Line (MNL) and Working Memory (WM) models. On this task, participants judged whether number pairs were in ascending or descending order. Whereas the MNL model predicts that ascending and descending orders should map onto opposite sides of space, the WM model predicts no such mapping. Moreover, we compared the spatial-order mapping for numerical and non-numerical sequences because the WM model predicts no difference in mapping. Across two experiments, we found consistent spatial mappings for numerical order along both horizontal and vertical axes, consistent with a MNL model. In contrast, we found no consistent mappings for letter sequences. These findings are discussed in the context of conflicting extant data related to these two models.     

受艾滋病影响儿童的歧视知觉在歧视经历和心理健康之间的作用分析

本研究旨在考察中国农村地区受艾滋病影响儿童(包括双孤儿童、单孤儿童和非孤儿童)在经历了父母感染艾滋病、父母因为艾滋病丧亡后的歧视经历和歧视知觉状况,及其对心理健康的影响.采用问卷调查了1221名被试,测查了他们的歧视经历、歧视知觉、心理健康(抑郁、孤独、自尊).经过数据分析发现:(1)歧视经历和歧视知觉存在显著的年龄段和儿童类别的差异,12岁及以下的儿童得分显著高于13岁及以上的,双孤儿童得分显著高于单孤儿童和非孤儿童;抑郁、孤独和自尊存在显著的儿童类别差异,双孤儿童、单孤儿童差于非孤儿童;且孤独和自尊还存在显著的年龄段差异,12岁以下的儿童差于13岁以上的;(2)不同歧视经历和歧视知觉的儿童在抑郁、孤独和自尊上存在显著差异,均是歧视经历、歧视知觉多的儿童抑郁和孤独严重、自尊低;(3)歧视经历对抑郁、孤独和自尊都有显著的预测作用,歧视知觉在其中起到了部分中介作用.     

大学生对艾滋病的乐观偏差

研究采用问卷法,以北京6所高校的278名被试为样本,考察了大学生对艾滋病的乐观偏差。结果表明,被试对艾滋病的感染和治愈存在着双重乐观偏差;艾滋病知识掌握程度既与感染艾滋病的乐观偏差无显著相关,也与治愈艾滋病的乐观偏差无显著相关。     

眼音距：一个揭示朗读过程中词汇加工的核心指标

朗读是一种出声的阅读方式,而测量朗读过程的一个重要的眼动指标就是眼音距。眼音距是指朗读过程中注视点和发音点之间的时间或空间距离,虽然这个概念早在1920年就提出来了,但直到近十年才受到较多关注,而对于其适用范围及心理学意义,认识尚不充分。本文从眼音距的概念提出和发展入手,分别分析了起始眼音距和结尾眼音距的计算方法和心理学意义,以及它们在快速命名和自然文本朗读任务中对阅读能力和认知控制的反映。未来研究可借助眼音距的特点和优势,进一步探讨朗读过程中副中央凹预视加工的特点和认知控制,以及揭示特殊群体在语言加工缺陷上的发生机制。     

背景音乐的节奏与歌词语言熟悉程度对驾驶行为和眼动的影响

摘要：采用3D模拟驾驶情景结合眼动技术探讨音乐节奏和歌词语言熟悉程度对驾驶行为和眼动规律的影响,研究结果表明：（1）驾驶经验对驾驶行为及眼动影响显著,新手与老手相比速度更慢、错误数更多;（2）音乐节奏对驾驶速度、眼跳和垂直搜索广度影响显著,快节奏与慢节奏相比,驾驶速度更快、平均眼跳距离更短、垂直搜索广度更短;（3）歌词语言熟悉程度对驾驶速度、错误数和平均注视时间影响显著,熟悉语言与陌生语言相比,驾驶速度更慢、错误数更多、平均注视时间新手更长,老手无影响。（4）节奏与语言共同影响驾驶过程中的水平搜索广度,陌生语言时快节奏的水平搜索广度高于慢节奏,熟悉语言时快节奏的水平搜索广度低于慢节奏。通过本实验,建议驾驶员在选择音乐时选择陌生语言歌词的音乐,音乐节奏则可视情况而定。
