In‐group representation and social value affect the use of in‐group identification for maintaining and enhancing self‐evaluation

Individuals with independent self‐construals identify with their in‐group in order to buffer threats to self‐esteem to a greater degree than do those with interdependent self‐construals. This study focused on the effect of the in‐group's social value and representation on this identification process among individuals who reported various real‐world threats to their self‐esteem. We conducted a questionnaire survey for university students and we examined how self‐construal, the in‐group social value, and the in‐group representation either moderate or mediate the relationship between threat to self‐esteem and identification with their academic departments. The results of multiple‐group analyses of structural equation modelling showed that independents who reported more threats to their self‐esteem identified with the in‐group when it was high in social value. In contrast, they did not exhibit in‐group identification when it was low in social value. Interdependents showed less in‐group identification regardless of the in‐group's social value. The representation of the in‐group as a common identity group mediated the relationship between threat to self‐esteem and in‐group identification for independents, whereas the representation of a common bond group played the same role for interdependents. These findings suggest the importance of considering the role of self‐construal and the in‐group social value, along with the representation of in‐group, in understanding in‐group identification in situations of threat to self‐esteem.     

两种训练方法对幼儿在园欺负行为的影响

该研究为了减少幼儿在园欺负行为,采用情境讨论法、角色扮演法对36名中班幼儿和39名大班幼儿的欺负行为进行为期一个月的训练.结果发现:角色扮演法和情境讨论法对减少幼儿的在园欺负行为都产生了一定的影响,但角色扮演法对幼儿在园欺负行为的影响效果显著,而情境讨论法的影响效果不显著,同时这两种训练方法的影响效果之间无显著性差异;训练对中班和大班幼儿的欺负行为都起到了一定的矫正作用,中班幼儿的在园欺负行为下降水平略高于大班幼儿,但并没有达到显著性差异;训练对减少中班男生和大班女生的在园欺负行为更有效果.     

Temporal Relationship Between Change in Subjective Distress and PTSD Symptom Decrease During Prolonged Exposure Therapy for Posttraumatic Stress Disorder

There is growing evidence that change in distress is an indicator of change during Prolonged Exposure (PE) for posttraumatic stress disorder (PTSD). However, temporal sequencing studies investigating whether change in distress precedes PTSD symptom decline are lacking. These studies are essential since the timeline between indicators of change and treatment outcome is a key assumption for mediation. The aim of the present study was to assess the temporal relationship between within- and between-session change in subjective distress and PTSD symptom decrease. We analyzed session data from 86 patients with PTSD. Data were analyzed using dynamic panel models. We distinguished temporal effects (within-persons) from averaged effects (between-persons). Results regarding the temporal effect showed that within-session change in subjective distress preceded PTSD symptom improvement while the reversed effect was absent. Averaged within-session change in subjective distress was also related to PTSD symptom improvement. Results regarding the temporal effect of between-session change in subjective distress showed that it did not precede PTSD symptom improvement. Averaged between-session change in subjective distress was related to PTSD symptom improvement. This study provides evidence for within- but not between-session change in subjective distress as indicator of change during PE. We also found that the way of modeling potential indicators of change affects results and implications. We recommend future studies to analyze mediators during treatment using temporal rather than averaged effects.     

第三方惩罚中的规范错觉：基于公正世界信念的解释

惩罚规范在一定程度上会影响个体的惩罚行为, 但个体对惩罚规范的感知与实际规范之间可能存在差异, 这被称为规范错觉。为了更好地从这一角度理解第三方惩罚, 我们需要回答的是：第三方惩罚中是否存在规范错觉?如果存在, 其方向如何?会对个体自身的惩罚行为产生何种影响?实验1 (N = 449)和实验2 (N = 134)的结果表明, 在违规情境中, 人们往往低估了他人的惩罚水平, 这导致自身较低的惩罚行为。实验3 (N = 164)和实验4 (N = 284)进一步发现, 较弱的公正世界信念导致人们对他人惩罚水平的低估, 从而影响了自身的惩罚行为, 而社会距离调节了公正世界信念对规范错觉的影响。上述结果表明, 规范错觉会受到内部(公正世界信念)和外部(社会距离)两个参照点的影响, 同时也在一定程度上说明第三方惩罚是一种注重维护规范的积极行为、而非注重个人收益的策略行为。     

儿童期虐待对大学生公正世界信念的影响:有调节的中介模型

为探讨儿童期虐待对公正世界信念的作用及心理机制,本研究采用问卷法对929名大学生进行了调查,并采用潜变量模型对数据进行了分析。结果发现:(1)儿童期虐待显著负向预测大学生公正世界信念;(2)控制感在儿童期虐待与公正世界信念之间起完全中介作用;(3)家庭社会经济地位调节了儿童期虐待与控制感的关系,高家庭社会经济地位放大了儿童期虐待与控制感间的负相关。研究结果表明,可以通过预防儿童虐待和增强控制感等干预措施来提升公正世界信念,并且需要对高社会经济地位家庭的儿童虐待加大关注。     

流动儿童主观社会经济地位与问题行为的关系:公正世界信念与社会自尊的作用

采用问卷法对北京市897名流动儿童的主观社会经济地位、社会自尊、公正世界信念和问题行为进行问卷调查,探讨主观社会经济地位与问题行为的关系,并进一步考察公正世界信念的中介作用和社会自尊的调节作用。结果发现:(1)主观社会经济地位与社会自尊、公正世界信念呈显著正相关,主观社会经济地位、社会自尊、公正世界信念与问题行为呈显著负相关。(2)公正世界信念在主观社会经济地位与问题行为的关系中起中介作用。(3)社会自尊调节主观社会经济地位通过公正世界信念影响问题行为的中介路径。社会自尊水平较高时,公正世界信念的中介作用显著; 社会自尊水平较低时,公正世界信念的中介效应不显著。

Interaction strategies with advanced driver assistance systems

When using advanced driver assistance systems (ADAS) drivers need to calibrate their level of trust and interaction strategy to changes in the driving context and possible consequent reduction of system reliability (e.g. in harsh weather conditions). By investigating and identifying categories of drivers who choose inadequate interaction strategies, it is possible to address unsafe usage with e.g. tutoring lessons tailored to the respective driver category. This paper presents two studies investigating categories of drivers who apply different interaction strategies when using ADAS. Study I was designed as an exploratory field study with 37 participants interacting with a SAE level 2 system. For the exploratory study, it was important to observe and understand the interaction strategies in a driving context which entails the real complexity of the driving task. The experimental set-up of study II (simulator study), however, allowed to clearly interpret the interaction strategies as either calibrated or un-calibrated by varying the situational risk. Participants (N = 33) were driving in a situation where the system was either working reliably (low-risk condition) or in a situation where the system displayed repeatedly errors under harsh weather conditions (high-risk condition). Cluster analyses with the variables trust, monitoring behavior towards the system and usage behavior were performed to analyze potential categories of drivers. Extreme driver categories with interaction strategies indicative for both misuse and disuse were observed in both studies. In study I, drivers were categorized as either highly trusting attentive, moderately trusting attentive, moderately inattentive, inattentive or skeptical. In study II, drivers were categorized as either un-calibrated, calibrated, inconsistent or skeptical. Taken together, results underline the need of tutoring systems that are tailored for different driver categories.     

How the initial level of trust in automated driving impacts drivers’ behaviour and early trust construction

Trust in Automation is known to influence human-automation interaction and user behaviour. In the Automated Driving (AD) context, studies showed the impact of drivers’ Trust in Automated Driving (TiAD), and linked it with, e.g., difference in environment monitoring or driver’s behaviour. This study investigated the influence of driver’s initial level of TiAD on driver’s behaviour and early trust construction during Highly Automated Driving (HAD). Forty drivers participated in a driving simulator study. Based on a trust questionnaire, participants were divided in two groups according to their initial level of TiAD: high (Trustful) vs. low (Distrustful). Declared level of trust, gaze behaviour and Non-Driving-Related Activities (NDRA) engagement were compared between the two groups over time. Results showed that Trustful drivers engaged more in NDRA and spent less time monitoring the road compared to Distrustful drivers. However, an increase in trust was observed in both groups. These results suggest that initial level of TiAD impact drivers’ behaviour and further trust evolution.     

工作记忆训练诱发的神经可塑性——基于系列fMRI实验的脑区分布递减时空模型

工作记忆训练(Working Memory Training, WMT)诱发神经可塑性, 但其具体机制尚不明晰。为探索WMT改变正常人群大脑功能的时空特性, 以“扩展的智力顶额整合理论”和“神经效率假说”为依据, 采用逐层递进的5种方法, 分6个步骤来查究近20年来正常人群WMT的37篇fMRI文献。第一步, 用叙述性综述、频数分析和卡方检验法比较脑区激活模式和脑网络功能连接在WMT前后发生的改变, 发现WMT改变了大脑的5个联合区、7个宏观区和3个子区。其中, 额上回、顶下小叶和扣带回这3个子区各自激活减弱的报道文献数量多于其激活增强的, 且这种差异分别具有统计学意义。第二步, 采用激活似然估计法对其中26篇开展元分析, 发现大脑的3个子区激活减弱水平在WMT前后的差异具有统计学意义, 即额中回(BA6和8)、额上回(BA6)和前扣带回(BA24和32)。第三步, 综合定性和定量分析结果, 提出WMT脑区分布递减时空模型, 产生5个结果和讨论。第四步, 采用非参数检验进一步追踪WMT效应的调节因素, 发现训练的任务类型和时间分别对脑区激活的影响具有统计学意义。第五步, 针对正常人群WMT诱发神经可塑性的时空特性, 得出3个结论：第一, WMT改变了正常人群相应脑区的神经活动, 表现为减弱或增强, 但减弱更加突出, 且更新和较短时间的WMT倾向于诱发较多减弱; 第二, 这些神经活动变化主要发生在额顶叶联合区, 但也包括分别以颞叶、枕叶、扣带回及纹状体为主的联合区, 在一定范围内体现了整脑功能联合。这体现了WMT诱发神经可塑性的空间特性, 且符合“扩展的智力顶额整合理论”; 第三, 额中回、额上回、顶下小叶和扣带回(尤其前扣带回)这4个子区在激活减弱水平上重点展示了WMT神经可塑性的时间特性, 且符合“神经效率假说”, 恰好体现出“聪明的大脑更懒惰”。第六步, 指出WMT诱发神经可塑性的未来研究可能关注脑可塑性中的低活跃性、辨析额中回、额上回、顶下小叶和扣带回(尤其前扣带回)这4个子区在激活减弱水平上体现的时间特性、找寻训练减弱或增强大脑活动的综合性影响因素。
