Fostering Change-Oriented Behaviors: A Broaden-and-Build Model

Purpose

The purpose of this study was to develop and test a broaden-and-build model relating LMX to employees’ change-oriented behaviors (creative performance and taking charge) through the mediators of positive affect and psychological capital.

Design/Methodology/Approach

Time-lagged, two-source data were collected from 248 participants and 40 direct leaders, which composed a heterogeneous sample of professional jobs from a three-wave data collection strategy. Mplus was employed to test the proposed hypotheses.

Findings

We found that LMX predicts employees’ change-oriented behaviors through two sequential paths: (a) the positive affect mediates the relationship between LMX and employee psychological capital, and (b) psychological capital mediates the relationship between positive affect and employees’ creative performance and taking charge. Our results provide a logical explanation of the ‘broadening’ and ‘building’ mechanisms through which LMX enhances employees’ change-oriented behaviors.

Implications

This study specifically suggests affective and psychological mechanisms by promoting the broadening and building phases that facilitate the transformation of individual perceptions of LMX, positive affect, and psychological capital in explaining employees’ creative performance and taking charge.

Originality/Value

This study develops a broaden-and-build model of change-oriented behaviors and contributes to research on proactive behaviors in the context of leader-member relationships.

     

A Scanpath Analysis of the Risky Decision‐Making Process

In the field of eye tracking, scanpath analysis can reflect the sequential and temporal properties of the cognitive process. However, the advantages of scanpath analysis have not yet been utilized in the study of risky decision making. We explored the methodological applicability of scanpath analysis to test models of risky decision making by analyzing published data from the eye‐tracking studies of Su et al. (2013); Wang and Li (2012), and Sun, Rao, Zhou, and Li (2014). These studies used a proportion task, an outcome‐matched presentation condition, and a multiple‐play condition as the baseline for comparison with information search and processing in the risky decision‐making condition. We found that (i) the similarity scores of the intra‐conditions were significantly higher than those of the inter‐condition; (ii) the scanpaths of the two conditions were separable; and (iii) based on an inspection of typical trials, the patterns of the scanpaths differed between the two conditions. These findings suggest that scanpath analysis is reliable and valid for examining the process of risky decision making. In line with the findings of the three original studies, our results indicate that risky decision making is unlikely to be based on a weighting and summing process, as hypothesized by the family of expectation models. The findings highlight a new methodological direction for research on decision making. Copyright © 2016 John Wiley & Sons, Ltd.     

The dynamic influence of emotional words on sentence comprehension: An ERP study

In the present study, we explored the influence of emotional words on the semantic integration of their following neutral nouns during sentence comprehension. We manipulated the emotionality of verbs and the semantic congruity of their following (neutral) object nouns in sentences. Event-related potentials were recorded to the verbs, which were either negative or neutral, and to the object nouns, which were either semantically congruent or incongruent relative to the preceding contexts. We found an N400 and a P600 effect in response to the semantic congruity of the nouns when they followed the neutral verbs. However, the P600 (but not the N400) semantic congruity effect may have been attenuated when the nouns followed the negative verbs. Meanwhile, the negative verbs elicited a larger P2 and N400 than did the neutral verbs. The results indicate that the attention captured by emotional words impaired reanalysis of the following incongruent information, demonstrating a dynamic influence of emotional words on the semantic processing of following information during sentence comprehension.     

Functional connectivity dynamics during film viewing reveal common networks for different emotional experiences

Recent theoretical and empirical work has highlighted the role of domain-general, large-scale brain networks in generating emotional experiences. These networks are hypothesized to process aspects of emotional experiences that are not unique to a specific emotional category (e.g., “sadness,” “happiness”), but rather that generalize across categories. In this article, we examined the dynamic interactions (i.e., changing cohesiveness) between specific domain-general networks across time while participants experienced various instances of sadness, fear, and anger. We used a novel method for probing the network connectivity dynamics between two salience networks and three amygdala-based networks. We hypothesized, and found, that the functional connectivity between these networks covaried with the intensity of different emotional experiences. Stronger connectivity between the dorsal salience network and the medial amygdala network was associated with more intense ratings of emotional experience across six different instances of the three emotion categories examined. Also, stronger connectivity between the dorsal salience network and the ventrolateral amygdala network was associated with more intense ratings of emotional experience across five out of the six different instances. Our findings demonstrate that a variety of emotional experiences are associated with dynamic interactions of domain-general neural systems.     

后经验主义时代的理论心理学

随着经验实证主义的衰落,心理学迎来了后经验主义时代。在后经验主义时代,人们对理论和经验观察的关系有了新的理解。理论不再是经验观察的附属物,相反,经验事实是被理论决定的。理论不是经验事实的概括和归纳,而是一种文化历史的建构。后经验主义时代的理论心理学以库恩的范式论、现象学、释义学和社会建构论作为自己的哲学基础。理论的评价标准不再是与经验事实的一致性。因为经验事实由于受到理论的污染,不再是一种客观的标准。在后经验主义条件下,理论的评价标准可建立在概念和逻辑、价值观和意识形态、修辞与叙事以及实践和应用的水平上     

Age differences in recollection: three patterns of enhanced encoding

Memory encoding conditions can be manipulated in a variety of ways, and many of these methods result in improved recollection for both younger and older adults relative to baseline conditions. Previous results have shown differential age-related patterns of improvement, however, with some manipulations giving equal improvement to young and old participants, some benefiting older adults more, and others benefiting younger adults more. In 2 experiments, the authors show that presenting pictures with words benefited older more than younger participants, word generation benefited both groups equally, and an encoding condition requiring novel integrative processing benefited younger more than older adults. The authors discuss these results in terms of the enhanced elaboration afforded and processing demanded by differential combinations of age groups and encoding conditions.     

为教育公平辩护

当了四十多年教书匠,天天同学生打交道,常常想的是如何“传道、授业”,做一个好教师,从未认真思考过“什么是教育”、“教育的本质”这类“形而上”的问题。这次同李小鲁同志一块学习和研究,才浮光掠影地读了一些教育哲学方面的论著,结合教育领域的问题,作了一些粗浅的思考。自开放改革起动以来,各行各业的改革都红红火火,惟有教育战线的改革举步为艰。教育领域存在的问题关系到千家万户,尤以教育公平问题最突出,是广大群众最为关心、意见最大的问题之一。小鲁同志是从事教育管理的官员,面临着层出不穷的矛盾与困难,他并没有埋没在各种繁杂…     

胰岛素抵抗与非酒精性脂肪性肝病

非酒精性脂肪性肝病是一种以肝细胞脂肪变性和脂肪贮积为病理特征但无过量饮酒史的临床综合征。肥胖、2型糖尿病和高脂血症被认为是非酒精性脂肪性肝病的重要危险因素。有研究表明胰岛素抵抗与非酒精性脂肪性肝病密切相关。脂质代谢异常、氧应激反应、瘦素、脂联素等与胰岛素抵抗的发生有相互作用,也影响着非酒精性脂肪肝病的发生发展。胰岛素抵抗在非酒精性脂肪性肝病发病机制上的作用以及与胰岛素抵抗相关的发病因素值得关注。通过体育锻炼与控制饮食热量逐渐减轻体重,并配合血糖及血脂的控制对非酒精性脂肪性肝病患者十分重要。
