心理契约破坏对组织公民行为的影响：同事支持感的调节作用

采用问卷调查法,研究了同事支持感（perceived coworker support）在心理契约破坏和组织公民关系间的调节作用。研究结果表明：同事支持感会削弱心理契约破坏和组织公民行为的关系的强度,即当个体感知到较高程度的同事支持,虽然个体感受到心理契约被破坏,也会维持较高程度的组织公民行为。     

Social Support at Work and Affective Commitment to the Organization: The Moderating Effect of Job Resource Adequacy and Ambient Conditions

ABSTRACT

This study investigated whether both supervisor and coworker support may be positively related to affective commitment to the organization on one hand; and on the other hand, it examined the moderating effect of job resource adequacy and ambient conditions on these relationships. The sample included 215 participants working within a health care organization. Results of regression analysis showed that supervisor and coworker support have an additive effect on affective commitment. Hierarchical regression analyses indicated that supervisor and coworker support are more strongly related to affective commitment when job resource adequacy is high. Furthermore, ambient conditions moderate the relationship between supervisor support and affective commitment in such a way that favorable ambient conditions strengthen this relationship. Overall, these findings reinforce the importance of taking into account contingent factors in the study of antecedents of affective commitment to the organization.     

Job crafting mediates how empowering leadership and employees’ core self-evaluations predict favourable and unfavourable outcomes

ABSTRACT

Based on job crafting theory and workplace resources theories, the present study develops a model of both antecedents and consequences of job crafting. We hypothesized subordinates’ perceptions of empowering leadership and core self-evaluations influence employee job crafting behaviours, which subsequently influence four outcomes: improving three employee well-being outcomes, (a) work-family enrichment, (b) flourishing, and (c) life satisfaction; and simultaneously reducing the organizational outcome of (d) deviant behaviours. Three-waves of data over nine months were collected from U.S. full-time employees (n = 276). Results showed empowering leadership and core self-evaluations positively related to expansive/approach forms of job crafting behaviours, which in turn related to the three different well-being outcomes. However, job crafting did not affect employee deviant behaviour. Instead, empowering leadership and core self-evaluations directly predicted less deviant behaviour. With the imputed data, we also found job crafting had a significant but weak relationship with deviant behaviour. These findings provide an integrated understanding of how and why employees engage in job crafting, and the important influence that job crafting has on employees’ subjective well-being. The present study advances leadership and job crafting theories, providing practical recommendations for promoting employee well-being and decreasing undesirable behaviours in the form of workplace deviance.     

2~4岁普通话儿童前注意阶段的声调感知机制

以MMN、p-MMR作为汉语词汇声调感知的神经关联物,探究2~4岁汉语普通话儿童前注意阶段对声调刺激的失匹配响应,关注范畴信息和偏差大小两个因素对儿童感知水平的影响。结果显示:在范畴间大偏差条件下(T1/T3),诱发明显的MMN;在范畴内或小偏差条件下(T3a/T3、T3b/T3、T2/T3),都未诱发显著的MMR。表明:2~4岁普通话儿童正处于声调感知能力的发展过程中,音位信息和声学信息共同影响其声调感知。     

Memory for temporal order in novel sequential action

ABSTRACT

Order is critical for many daily activities. Developmental research has shown that memory for order in action is the least prioritised in a processing hierarchy, and is sensitive to deviant input. The current research investigated these aspects of sequence learning are also present in adults. Participants learned a novel sequence across several exemplars with either easy- or difficult-to-categorize items, which either did or did not involve a deviant order on one exemplar, and were later asked to recall the sequence. Memory for individual sub-actions and order was stronger in the easy conditions, and the deviant order significantly deteriorated ordered recall in the difficult condition only. These findings support the theorised processing hierarchy, with the presence of a deviant order having a larger effect on memory when the load at the earlier item stage is increased. These results have implications for theories of working memory and learning in real-world contexts.
