Les profils recherchés et rejetés par des recruteurs professionnels en France

This research explores the expectations of recruiters in terms of what they think are prerequisite qualifications of applicants at different job levels. The professional recruiters (N=384) practicing in France, read a job profile (managers or blue-collar workers) and subsequently indicated the five most advisable and inadvisable characteristics for performance on the job. The results confirm our hypothesis and are evidence of a strong prevalence of personality traits in recruiters’ choices. Moreover, the profiles of the « ideal » and « unacceptable » personality mentioned by the recruiters differ according to the job level. Finally, for the management level as well as for the blue-collar worker level, the « ideal » profile is not a simple reversal of the « unacceptable » profile, each profile implies specific personality traits.     

企业组织的学习结构

在理论综述的基础上,通过访谈、预试和大规模调查,对企业组织学习结构进行了实证研究。根据访谈和预试,初步确定组织学习问卷的项目。采用探索性因素分析和验证性因素分析,对来自全国不同地区43家企业的管理者和员工的调查数据进行了分析。结果表明,我国企业组织学习是一个6因素的结构模型：组织间学习、组织层学习、集体学习、个体学习、利用式学习、开发式学习;组织学习问卷具有一定的信效度。组织学习的作用和影响因素以及这三者之间的复杂作用机制还有待更为深入的研究     

Insular activity during passive viewing of aversive stimuli reflects individual differences in state negative affect

People differ with regard to how they perceive, experience, and express negative affect. While trait negative affect reflects a stable, sustained personality trait, state negative affect represents a stimulus limited and temporally acute emotion. So far, little is known about the neural systems mediating the relationship between negative affect and acute emotion processing. To address this issue we investigated in a healthy female sample how individual differences in state negative affect are reflected in changes in blood oxygen level-dependent responses during passive viewing of emotional stimuli. To assess autonomic arousal we simultaneously recorded changes in skin conductance level. At the psychophysiological level we found increased skin conductance level in response to aversive relative to neutral pictures. However, there was no association of state negative affect with skin conductance level. At the neural level we found that high state negative affect was associated with increased left insular activity during passive viewing of aversive stimuli. The insula has been implicated in interoceptive processes and in the integration of sensory, visceral, and affective information thus contributing to subjective emotional experience. Greater recruitment of the insula in response to aversive relative to neutral stimuli in subjects with high state negative affect may represent increased processing of salient aversive stimuli.     

恶性肿瘤皮肤表现

恶性肿瘤皮肤表现可分为肿瘤直接效应与间接效应。直接效应是指恶性肿瘤或其转移灶生长影响周围器官或组织正常功能;间接效应是指恶性肿瘤或其转移灶经复杂生物学效应影响远处器官或组织正常功能,也称为副肿瘤性皮肤病。恶性肿瘤皮肤表现发病率根据原发肿瘤而束同,可能是患者潜在肿瘤首发临床表现,并且与肿瘤复发转移相关。     

Contextual control of human fear associations in a renewal paradigm

The original model of behavior change suggests that extinction is context dependent whereas fear acquisition is context independent [Bouton, M. E. & Ricker, S. T. (1994). Renewal of extinguished responding in a second context. Animal Learning and Behavior, 22, 317-324]. Supportive evidence stems mainly from animal studies, showing that after acquisition (conditioned stimulus-unconditioned stimulus (CS-US)) in Context A and extinction in Context B, fear is renewed by presenting the CS in acquisition Context A (ABA renewal) or in a novel Context C (ABC renewal). By implication, the model predicts equal ABA and ABC renewal. However, there is also evidence to suggest that the context dependency of extinction and the context independency of acquisition may be less stringent than originally proposed. The present study investigated renewal in humans using a differential fear conditioning paradigm with a shock US and online shock expectancy ratings and electrodermal responses as dependent variables. Experiment 1 compared an ABA condition with an AAA condition. Experiment 2 compared three conditions: ABA, ABC, and AAA. Both experiments demonstrated ABA renewal. Most importantly, Experiment 2 showed larger ABA than ABC renewal. Overall, results for expectancy ratings were more convincing than for electrodermal responses. In line with the extinction model, the present findings support the context dependency of extinction in humans. In contrast to the model, the findings suggest that in humans not only extinction learning, but also fear acquisition is controlled by its current context.     

Temporal distance and ease of retrieval

Construal Level Theory (CLT; Trope & Liberman, 2003) proposes that pro-arguments (pros) constitute high-level construals and counter-arguments (cons) low-level construals. Therefore, pros are more salient for distant-future actions than are cons and the reverse holds for near-future actions (Eyal, Liberman, Trope, & Walther, 2004). We further predicted and results from one experiment show that participants found it easier to generate pros if an action pertained to the distant rather than the near future. For cons the effect was reversed: participants found it more difficult to generate cons if the action pertained to the distant rather than the near future. Consequently, people were more in favor of the action if it pertained to the distant rather than the near future. Ease of retrieval mediated the effect of temporal distance on attitudes. The mutual relevance of the CLT framework and research on ease of retrieval is discussed.     

Explaining sex differences in infants' preferences for groups

Social organization of a species influences myriad facets of individuals’ behavior. Much research indicates that human social organization consists of males in large groups and females in smaller groups or interacting with individuals. This study analyzed the initial factors that produce greater preferences for groups by human male versus female infants. To this end, using a looking preference paradigm, fifty-nine 6–8-month-old infants viewed individual versus group images of actual children. On the basis of several controls, results demonstrated that male more than female infants are attracted to the complex level of stimulation provided by groups. Discussion centers on further identifying male versus female patterns of group interaction from a perceptual and cognitive standpoint.     

图片和汉字的激活水平及知觉干扰效应的比较

研究使用8个残缺水平下的图片及其中文名（汉字双字词）为实验材料．试图比较图片与汉字双字词识别激活水平的差异,接着比较二者产生知觉于扰效应的条件,并把二者产生知觉于扰的条件与英文单词产生知觉于扰的条件进行比较。实验一结果发现,在材料较清晰的条件下,汉字双字词的命名成绩高于图片,表明汉字双字词的激活水平不比图片低,但在材料很残缺的条件下,汉字双字词的命名成绩低于图片。实验二发现双字词和图片在没有事先学习情况下都产生知觉干扰效应,已有研究表明单个汉字无需事先学习也可以产生干扰效应,而英文单词需要事先学习。因此,图片和汉字的干扰效应与英文单词的差别跟图片、汉字的激活水平比英文单词高有关。     

联想启动与知觉启动的比较研究

采用快速命名方法探讨不同加工水平对联想启动效应的影响。被试分别在深、浅加工条件下学习一系列颜色词,然后完成颜色命名和再认任务,并设立词命名任务,以比较联想启动和知觉启动的异同。结果表明,在颜色命名任务中,深、浅加工条件下均可形成对颜色词的启动效应,但浅加工条件下的再认成绩明显低于深加工,出现了联想启动和再认的分离现象。词命名表现出与颜色命名相似的结果,但它们在有意识回忆方面仍存在一定的差异,提示知觉表征系统单独并不能支持联想启动,联想启动可能是多个记忆系统共同作用的结果。     

干预不同个体记忆内容对负性刺激诱发的情绪水平影响*

探讨记忆在情绪发生和调节中的作用,通过干预个体对负性刺激的记忆内容,研究了积极干预、消极干预和不干预三组被试在接受负性刺激后产生的情绪水平差异,以及不同认知方式个体对诱发情绪的不同反应。结果表明,干预类型对负性刺激诱发的消极情绪产生了一定影响:积极干预组和不干预组在消极情绪后测上的得分显著低于消极干预组,积极干预组与不干预组的得分差异不显著。认知方式、性别及干预顺序对诱发情绪的影响不显著。结论:干预记忆内容可影响负性刺激诱发的消极情绪水平,接受积极干预比消极干预产生的消极情绪水平更低,因此对记忆内容的积极干预可有效降低产生的消极情绪水平。
