Guanxi networks and members' effectiveness in Chinese work teams: Mediating effects of trust networks

The present study examined 33 teams with a total of 206 team members (excluding team leaders) to explore the effects of intrateam guanxi and trust networks on individual effectiveness in Taiwan. Guanxi networks included non-job, departmental and past team networks, while trust networks included affective and cognitive trust networks. Results showed that: (i) guanxi networks could better explain members' effectiveness compared with relational demography, and different guanxi networks had different effects; (ii) the more central an individual's position was in the cognitive trust network, the higher the individual's effectiveness; (iii) the past team guanxi network of a team member displayed a positive effect on the centrality of cognitive trust network, while non-job and departmental guanxi networks showed negative effects; and (iv) the effects of members' guanxi networks on individual effectiveness were mediated by the centrality of trust networks.     

Ask me why,don't tell me why: Asking children for explanations facilitates relational thinking

Identifying abstract relations is essential for commonsense reasoning. Research suggests that even young children can infer relations such as “same” and “different,” but often fail to apply these concepts. Might the process of explaining facilitate the recognition and application of relational concepts? Based on prior work suggesting that explanation can be a powerful tool to promote abstract reasoning, we predicted that children would be more likely to discover and use an abstract relational rule when they were prompted to explain observations instantiating that rule, compared to when they received demonstration alone. Five- and 6-year-olds were given a modified Relational Match to Sample (RMTS) task, with repeated demonstrations of relational (same) matches by an adult. Half of the children were prompted to explain these matches; the other half reported the match they observed. Children who were prompted to explain showed immediate, stable success, while those only asked to report the outcome of the pedagogical demonstration did not. Findings provide evidence that explanation facilitates early abstraction over and above demonstration alone.     

基于贝叶斯网模型的多级计分诊断测验分类及比较研究

贝叶斯网模型提供了一种方便和直观的框架结构来表示变量间的关系,非常适合在诊断测验中对教育评估的内容进行建模。本研究将两种贝叶斯网分类模型与序列多级计分诊断模型S-GDINA进行综合比较。考察两种贝叶斯网分类模型与S-GDINA在Q矩阵正确界定和包含一定比例(25%、 30%)的错误时,两者对被试的分类性能;并将贝叶斯网分类模型应用到实证数据中,展示贝叶斯网分类模型在实证数据中的分类过程和分类性能。研究结果表明：当Q矩阵由专家正确界定时,朴素贝叶斯分类模型的分类效果与S-GDINA模型相差不大,同样可以达到很好的分类效果,树增广的朴素贝叶斯分类模型的分类性能也能达到良好。实证结果进一步表明,将贝叶斯网分类模型应用于教育测量领域中的诊断分类工具是有其优势和可行的,尤其是当测验数据对于所选用诊断模型的拟合较差、测验的Q矩阵中包含错误或测验数据中包含较多的噪音时。     

Freedom in the Body: The Physical, the Causal, and the Possibility of Choice

Abstract. In Minding God Gregory Peterson takes a careful look at the kind of freedom that human persons have. He concludes that humans are constrained to be free and unpacks this into a version of compatibilism. That is, humans are not metaphysically free under current existence because of the causal determination inherent in their physical nature, but they can take credit for the origination of selfforming decisions because the causes occur inside of us. Peterson does advocate an eschatological hope looking forward to the breaking of causal determination by God's own action. Thus, Minding God presents an eschatologically limited compatibilism. Compatibilism of any kind, however, presents serious challenges to most Christian theologies and to many religious traditions broadly considered. After I interpret Peterson's position I make the argument that compatibilism is neither desirable nor required for a theological anthropology intent on serious engagement of cognitive science.     

Connecting the Many Levels and Facets of Cognitive Aging

Basic cognitive mechanisms, such as the abilities to briefly maintain, focus, and process information, decline with age. Related fields of cognitive aging research have been advancing rapidly, but mostly independently, at the biological, information processing, and behavioral levels. To facilitate integration, this article reviews research on cognitive aging at the different levels, and describes a recent integrative theory postulating that aging-related deficiencies in neurotransmission cause increased noise in information processing and less distinctive cortical representation, which in turn lead to cognitive deficits. Aging-related attenuation of catecholaminergic modulation can be modeled by lowering a neural network parameter to reduce the signal-to-noise ratio of information processing. The performance of such models is consistent with benchmark phenomena observed in humans, ranging from age differences in learning rate, asymptotic performance, and interference susceptibility to intra- and interindividual variability and ability dedifferentiation. Although the details of the conjectured sequence of effects linking neuromodulation to cognitive aging deficits await further empirical validation, cross-level theorizing of the kind illustrated here could foster the coevolution of related fields through cross-level data synthesis and hypothesis testing.     

Revisiting a meta-analysis of helpful aspects of therapy in a community counselling service

This small scale mixed methods study examines helpful events in a community counselling setting, categorising impacts of events according to Timulak’s [(2007). Identifying core categories of client-identified impact of helpful events in psychotherapy: A qualitative meta-analysis. Psychotherapy Research, 17, 305–314] meta-synthesis of significant events research. Comparisons were made between the types of impacts reported as helpful by clients receiving cognitive behavioural therapy (CBT) or relational integrative counselling. Seventy-five clients identified 291 significant events on 216 Helpful Aspects of Therapy (HAT) forms. The findings broadly reflect all nine impacts identified by Timulak (2007). The study also suggests that a potential new category, ‘voicing’ may exist. Differences between the types of impacts reported as helpful by clients in CBT and integrative therapy showed a higher percentage of CBT clients reporting ‘behavioural change/problem solution’, ‘reassurance’ and ‘client involvement’ as helpful. Differences in other categories were not statistically significant.     

The longitudinal association between social status insecurity and relational aggression: Moderation effects of social cognition about relational aggression

Previous research has shown that adolescents’ insecurity about their social status is related to their use of relational aggression. However, little is known about how adolescents’ social cognition may moderate this association. Employing a mixed-method approach and a short-term longitudinal design, this study addresses this issue by examining the moderation effects of attribution and outcome expectancies regarding relational aggression on the associations between social status insecurity and relational aggression among 476 Chinese adolescents (238 girls). The main results showed that self-serving attributions and instrumental outcome expectancies strengthened the positive and longitudinal association between social status insecurity and self-reported relational aggression. The findings of this study enrich our knowledge about the social cognitive processes pertinent to peer status and relational aggression among adolescents.     

社会交往对老年人认知功能的影响

社会交往是影响老年人认知功能的重要因素。社会交往主要包括社会网络, 社会支持和社会参与三方面。研究发现, 社会交往对老年人的认知功能具有积极的影响, 但是网络类型比网络规模更有利于揭示社会网络与认知功能的关系, 而且社会支持并非越多越好, 对于易感性人群而言, 适度的支持才能避免造成认知损伤。此外, 尽管社会参与能够对认知功能产生持续的保护作用, 但不同活动类型作用于不同的认知领域。未来研究应该继续深化社会网络类型的作用, 进一步考察社会支持与认知功能的中介和调节变量, 并同时关注社会活动对认知功能的干预研究。     

贝叶斯网在认知诊断属性层级结构确定中的应用

K. K. Tatsuoka和她同事研究的规则空间模型(RSM)是一种在国内外有较大影响的认知诊断模型, 但是Tatsuoka的RSM是由学科专家先从已编制的测验中抽取出属性, 然后给出测验的关联Q阵, 再由该Q阵导出属性间的层级关系。已有研究证明, 这种做法所得到的属性间的层级关系难以保证是正确的, 甚至难以保证属性间的层级关系是唯一确定的。这里利用贝叶斯网进行结构学习, 从被试的属性掌握模式中挖掘出属性间的层级关系, 学习所得到的层级关系可以用来验证由RSM中的方法得到的层级关系。模拟实验和实证研究的结果都显示了该方法所得到的属性层级关系是有参考价值的, 可以为命题或测量专家带来有用的信息。

From relation to the field: Modes of unconscious fantasy elaborations1

Abstract

Relational and field theories have much in common, despite divergent foundations. In this paper, several areas of divergence are selected, including the structure of the field as a relational matrix or as an unconscious joint fantasy of the couple; the fate and form of insight; and the nature of the unconscious as relational or ubiquitous. Differences in cognitive and attentional sets are identified and linked to different modes of insight. Using a clinical vignette, these divergences will be illustrated with an attempt to compare and contrast the two approaches through a discussion of how each lens highlights, expands, or forecloses different features of the analytic process. A mode of conceiving the unconscious as unstructured and multiple in potential is offered to reconcile divergent assumptions in therapeutic action. A consideration of Sandor Ferenczi’s clinical emphasis on relaxed technique, elasticity, and especially mutuality suggests that he would have been a field theorist were he among us today.     

Teaching Genesis: A Present-Day Approach Inspired by the Prophet Nathan

The prophets Nathan (2 Samuel 12:1–15) and John the Baptist (Mark 6:16–28) had comparable tasks before them: to convince their respective kings about the wrongs of taking somebody else's wife and marrying her. Nathan succeeded, while John failed and furthermore lost his life. What made the difference? One possible explanation is that Nathan proceeded in two steps: (1) Tell an interesting, nonthreatening story that nevertheless makes the point at issue; (2) transfer that message to the case at hand. In contrast, John used a direct approach, which raised apprehension, even fear (on the part of Herodias, the woman involved), and led to failure. That lesson has wider applications, as illustrated here for teaching the biblical Genesis narration. The other ingredient in this teaching is relational and contextual reasoning (RCR), the use of which is also indicated for other issues besides teaching Genesis.

Evaluations of relational aggression as a function of relationship type and conflict setting

The present study examined influences on girls' evaluations of relational aggression situations. Second‐, third‐, fifth‐, and sixth‐grade girls evaluated four relational aggression conflict scenarios in terms of attributions of aggressor's intentions, evaluator's behavioral response, evaluator's affective state, and how likely the situation was to actually occur. Girls evaluated intentions of a best friend more positively, reported being more mad at an enemy, and perceived conflict to be more likely to occur with an enemy than a best friend. Aggressor intentions in direct conflict scenarios (aggressor said something mean to evaluator) were perceived as more negative than aggressor intentions in indirect conflict scenarios (aggressor said something mean about evaluator to another peer). Younger girls reported intentions of their enemy as being more positive than did older girls. Further, older girls reported intentions of their best friend as being more positive than intentions of their enemy. Older girls also were more accurate in conceptualizing variations in the conflict setting (direct, indirect) and responding in a context‐consistent manner. Findings are discussed in terms of the social‐relational and social‐situational processes that influence children's evaluations of relational aggression and how the current study extends previous research on relational aggression.

The Development of Family Loyalty and Relational Ethics in Children

Despite little research investigating how family loyalty and relational ethics develop in children, theorists suggest that children's early family loyalty experiences play a significant role in their future relationships. Twenty-four children, ages 5–10 years, were interviewed to examine developmental trends in children's conceptualizations of family and family loyalty and their reasoning through parent-child ethical dilemmas. Results indicate (a) younger children possess a simpler, more concrete schema for family and family loyalty than do older children and (b) younger children are less able than older children to adopt their parents' perspectives in reasoning through ethical dilemmas.A psychotherapist with T.
