The relationship between career growth and organizational commitment

This research examines the relationship between employees' career growth and organizational commitment. Career growth was conceptualized by four factors: career goal progress, professional ability development, promotion speed and remuneration growth, while organizational commitment was conceptualized using Meyer and Allen's (1997) three component model. Survey data, collected from 961 employees in 10 cities in the People's Republic of China, showed that the four dimensions of career growth were positively related to affective commitment, and that three of the facets were positively related to continuance and normative commitment. Only three of eighteen two-way interactions among the career growth factors affected organizational commitment, suggesting that the career growth factors influence commitment in an additive rather than a multiplicative manner.Results focus on how career growth can be used to manage organizational commitment.     

Moral Credentialing and the Rationalization of Misconduct

Recent studies lead to the paradoxical conclusion that the act of affirming one's egalitarian or pro-social values and virtues might subsequently facilitate prejudiced or self-serving behavior, an effect previously referred to as "moral credentialing." The present study extends this paradox to the domain of academic misconduct and investigates the hypothesis that such an effect might be limited by the extent to which misbehavior is rationalizable. Using a paradigm designed to investigate deliberative and rationalized forms of cheating (von Hippel, Lakin, & Shakarchi, 2005), we found that when participants had credentialed themselves (versus a non-close acquaintance) via a set of hypothetical moral dilemmas, they were more likely to cheat on a subsequent math task, but only if cheating was highly rationalizable. When cheating was difficult to rationalize, moral credentialing had almost no impact on cheating.     

Role stressors and counterproductive work behavior: The role of negative affect and proactive personality

Based on the stressor‐emotion model, we propose that negative affect mediates the relationship between three role stressors (i.e., role ambiguity, role conflict, and role overload) and counterproductive work behavior (CWB), while proactive personality moderates the relationships between negative affect, role stressors, and CWB. We tested our hypotheses using data from 332 employees in Mainland China. We found that negative affect mediated the relationships between the three dimensions of role stressors and CWB. Role ambiguity was most strongly associated with CWB, followed by role conflict and then role overload. Proactive personality moderated the role ambiguity‐negative affect, role conflict‐negative affect, and negative affect‐CWB relationships, but not the relationship between role overload and negative affect.     

荷包牡丹碱对受低强度训练的小鸡的记忆形成的影响

在小鸡一次性被动回避行为中,低强度训练的动物其长时记忆保持不良,而训练前１０或２０分钟注射γ－氨基丁酸能颉颃剂荷包牡丹碱,可明显提高长时记忆的保持水平,这一作用可被激动剂蝇蕈碱反转。记忆保持曲线进一步显示,受低强度训练的动物其记忆仅能保持至训练后２０分钟,而注射荷包牡丹碱可使记忆至少延长至训练后１２０分钟。上述结果提示：小鸡的记忆形成受γ－氨基丁酸能系统的调节;γ－氨基丁酸能系统虽然直接参与中时记忆,但对长时记忆的形成似乎也是必需的。     

不同注意条件下的知觉启动及其机制

采用快速命名方法探讨不同注意条件下的知觉启动效应及其机制。实验中呈现一系列颜色词,要求被试分别完成集中和分散注意任务,然后进行词命名和再认测验。在词命名任务中．实验1包括旧词、重组颜色词和新词,而在实验2中重组颜色词改为新颜色词。结果表明,在实验1中,只有在集中注意条件下,被试对旧词的命名时间明显短于重组颜色词．即表现出知觉启动效应。而在实验2的两种注意条件下,被试对旧词的命名时间均明显短于新颜色词。这提示,在不同注意条件下的学习会影响其后的颜色知觉启动,并且与词和颜色的联结捆绑有关。

人类技巧学习的脑功能成像研究进展

近10年来的脑功能成像研究表明,人类技巧学习是一个动态过程。在这一过程中,有关脑区的活动发生了阶段性的变化。在学习的早期阶段,由于神经元选择性提高,有关脑区的活动减弱;而在晚期,由于新神经元的参与,有关脑区的活动增强。脑区活动的阶段性变化还可能与学习过程中被试对任务的意识和加工策略的转变有关。在学习过程中,不同脑区之间逐渐建立联系并组成临时任务指向性系统,这一系统受到额叶等联合皮层的调控。     

Adaptive influence of long term high altitude residence on spatial working memory: An fMRI study

With an increasing population living at a high altitude (HA), the impact of HA residence on human cognitive function has raised concerns. We recruited two groups of college students with one group born and grew up at HA until early adulthood and the control group born and grew up at near sea level (SL); the two groups were matched at age, gender ratio, educational level, the ancestral lines, and peripheral physiology (especially the hemoglobin concentration). A 2-back spatial working memory task was performed by each subject in the scanner while fMRI data were acquired. Compared to the SL control group, the HA group showed equal response accuracy, with more variance in reaction time and a larger average value. fMRI data indicated that both groups showed common activation patterns in the neural pathway typically associated with working memory. The HA group had greater activation at the left pyramis, the left superior temporal gyrus and less activation at the left middle occipital gyrus. Significant correlations were found within each group between the reaction times and BOLD signal change amplitudes at the frontal cortex and the precentral cortex.     

Perceived racial discrimination as a barrier to college enrollment for African Americans

African Americans trail European Americans in terms of academic achievement, even when accounting for differences in socioeconomic status. One cause of this gap may be racial discrimination. In the current article the authors hypothesized that early perceived racial discrimination (by 5th grade) would predict college enrollment, mediated by changes from 7th grade to 10th grade in academic orientation, college aspirations and expectations, and deviance tolerance. Participants were 750 African Americans from the Family and Community Health Study. A structural equation model that controlled for socioeconomic status and earlier academic performance supported the hypothesis, with the exception that discrimination did not influence aspirations. The effect of discrimination on expectations, however, was moderated: Participants with high future orientation maintained high expectations in spite of discrimination. These results suggest that discrimination discourages some African Americans from pursuing higher education and that increasing future orientation may promote African Americans' college enrollment.     

Competition and sensemaking in ethical situations

Competition was examined in relation to ethicality. The effect of a competitor being an in‐group vs. out‐group member, the competitor offering uncorroborated or corroborated information, and the impact of the competitor goals were examined. The findings suggest that the way competition is presented has an important influence on how individuals make sense of an ethically ambiguous situation and make ethical decisions. A main effect was found, such that when a competitor offered uncorroborated information, participants made less ethical decisions and used pro‐ethical reasoning strategies less often. An additional main effect was found suggesting that participants made more ethical decisions when working with an in‐group competitor rather than an out‐group competitor. Complex interactive effects were also found and discussed.
