Enhanced conflict-driven cognitive control by emotional arousal,not by valence

Emotion is widely agreed to have two dimensions, valence and arousal. Few studies have explored the effect of emotion on conflict adaptation by considering both of these, which could have dissociate influence. The present study aimed to fill the gap as to whether emotional valence and arousal would exert dissociable influence on conflict adaptation. In the experiments, we included positive, neutral, and negative conditions, with comparable arousal between positive and negative conditions. Both positive and negative conditions have higher arousal than neutral ones. In Experiment 1, by using a two-colour-word Flanker task, we found that conflict adaptation was enhanced in both positive and negative contexts compared to a neutral context. Furthermore, this effect still existed when controlling stimulus–response repetitions in Experiment 2, which used a four-colour-word Flanker task. The findings suggest emotional arousal enhances conflict adaptation, regardless of emotional valence. Thus, future studies should consider emotional arousal when studying the effect of emotion on conflict adaptation. Moreover, the unique role of the emotional context in conflict-driven cognitive control is emphasised.     

网络与现实:人际关系的质量差异

研究探讨网络与现实人际关系质量的差异。实验一考察匿名下被试在网络与现实中自我表露水平;实验二考察被试在网络和现实情境中对他人人格品质的评价;实验三使用内隐联想测验探讨被试对网络维持不同亲疏关系的态度。结果:(1)匿名下被试在现实中更多表露自我;(2)被试对现实他人的品质有更积极的评价,同时交友意愿更强;(3)无论亲疏关系,被试对网络维持人际关系持否定态度。结论:现实人际关系质量优于网络人际关系。     

刺激前负波:奖赏期待的电生理指标

刺激前负波(Stimulus-Preceding Negativity,SPN)是从关联性负变化中分离出来的非运动性慢电位,其波幅随着反馈刺激的临近逐渐升高。先前研究侧重于将SPN视为一种认知性成分,而最近的研究支持了SPN是奖赏期待的可靠指标。本文从奖赏的基本属性、结果评价、神经发生源以及特殊人群等角度,对SPN反映奖赏期待这一假说进行了梳理,并提出了未来的研究方向,旨在为研究奖赏期待受损的神经精神类疾病提供可靠的生物学标记。     

The stories we keep: autobiographical memory in American and Chinese middle-aged adults

One hundred and eight European American and Chinese adults, aged between 38 and 60, participated in this questionnaire study. They each recalled 20 memories from any period of their lives. Memory content was analyzed as a function of culture (U.S. and China), life period (childhood, youth, early midlife, and peak midlife), and gender (female and male). Across the four life periods, Americans provided more memories of individual experiences and unique, one-time events and focused on their own roles and emotions. In contrast, Chinese were more inclined to recall memories of social and historical events and placed a great emphasis on social interactions and significant others in their memory narratives. Chinese also more frequently drew upon past events to convey moral messages than did Americans. In addition, memory content evidenced age-related increases in both autonomous and social orientations. Findings are discussed in light of the self-definitional and directive functions of Autobiographical memory in the context of culture.     

Agreement in personality judgments within and between nonoverlapping social groups in collectivist cultures

The social context hypothesis states that people behave differently in different social groups because group norms and context-specific interpersonal relationships uniquely affect behavior. Consequently, a person who is a member of different, nonoverlapping social groups (i. e., the members of different groups are unacquainted) should be judged consensually on personality traits within each group; however, between groups there should be less agreement in judgments. This research focused on cultural moderation of the social context effect in two collective cultures (China and Mexico) with different norms for interpersonal relationships. Among Chinese, there was greater consensus in trait judgments within groups than between groups, whereas in Mexico, agreement within and between groups was equivalent. Culturally based relationship norms that affect cross-context consistency of behavior and, in turn, the consistency of trait judgments across groups were described.     

Earliest recollections of self and others in European American and Taiwanese young adults

This study examined the age and content of earliest childhood memories of self and others. European American and Taiwanese participants (N= 111) retrieved their earliest memories in response to the cue words self, mother, family, friend, and surroundings. Memory for mother was from an earlier age than memory for self, and memories for mother, family, and friend were more socially oriented in content than memories for self or surroundings. In addition, in response to all cue words, Euro-Americans recalled memories from an earlier age than did Taiwanese. Euro-Americans also had a greater tendency to report memories of specific events and focused more on their own roles and autonomy than did Taiwanese, who more often described routine events and emphasized the roles of others. These findings have important implications for infantile amnesia and the memory-self interplay.     

企业职工的工作价值观特征分析

企业管理者可以借助三种不同的力量来激励和影响职工的工作行为 ,一种是外在的经济力量 ,一种是与工作相关的内在激励 ,还有一种是以人的信念和价值观念为基础的影响力。前两种行为激励是组织行为学研究的传统领域 ,而工作价值观则是近来随着组织文化的兴起而提出的新课题。本研究以企业现场调查为基础 ,分析了企业职工的工作价值观的特点 ,指出工作价值观是由工作行为评价因素、组织集体观念因素和个人要求因素三个方面构成 ,它们与职工的工作动机有着显著的相关。职工的工作价值观还表现出年龄的差异 ,年轻职工 (3 0岁以下 )的工作价值观并不是与年长的职工 (3 0岁及以上 )完全不同 ,他们在工作行为评价因素、组织集体观念因素方面有着共同之处 ,但是他们在考虑问题和判断时 ,思想更复杂 ,更多地考虑个人要求因素。不同所有制企业中的职工 ,其工作价值观也存在着一定的差异 ,其中 ,国有 /集体企业职工的组织集体观念显著地高于外资 /合资企业职工。     

运算动量效应的理论解释及其发展性预测因素

了解运算偏差的形成与发展对探索算数运算系统的内在机制具有重要意义,早期的算数运算能力是儿童理解和进行复杂数学运算的基础。运算动量偏差是指个体在进行基本数学运算时倾向于高估加法运算结果而低估减法运算结果的一种运算偏差,主要包括三种理论解释,即注意转移假说、启发式解释和压缩解释。鉴于运算动量效应在成年群体中相对稳定却在不同发展阶段儿童中存在不一致的证据,数学能力的提高与空间注意的成熟可结合不同的理论解释来阐明儿童发展过程中运算动量效应的变化趋势。未来可以进一步整合多种研究任务以揭示运算动量效应的发展轨迹,考察数量表征系统与运算动量效应间的关联,探究运算动量效应在不同运算符号中的稳定性,探讨不同因素共同作用对运算动量效应的影响,并设计有关数学能力的干预措施以减少运算动量效应这一运算偏差。     

婴儿客体永久性发展机制的研究

客体永久性是婴儿早期发展中一项重要的心理能力,本研究以２０８名８－１１个月的婴儿为被试,采用实验法和访谈法探讨了婴儿客体永久性的发展机制及其发展趋势问题。结果表明：１）我国婴儿的爬行与其客体永久性的发展无直接关系,支持了爬行对婴儿客体永久性发展的作用可能来自爬行经验而不是爬行动作的假设：２）我国婴儿的客体永久性随年龄增长而持续发展,提示爬行并不是客体永久性发展的唯一途径,爬行不能发挥作用时,婴儿的客体永久性可以通过其它途径得到发展;３）在８－１１个月间,我国婴儿的客体永久性达到了阶段Ⅳ水平,８个月的婴儿已经具备了初步的客体永久性。从发展速度来看,婴儿的客体永久性在８、９个月间发展较为迅速,出现了显著的发展性变化,在９－１１个月间没有显著的差异。
